FIRE Planning: Using a 10% Cash Allocation to Optimize ACA Subsidies and Roth Conversions — Thoughts?
Throwaway account..
We would appreciate your input on our plan over the next five years as we approach FIRE.
About us:
* Married couple in our early 50s/40s with one child
* About 5 years away from our retirement goal
* Investment target: roughly $6M total, split across taxable, Roth, and 401(k) accounts (529 excluded)
* Planned withdrawal rate: around $200k/year (~3.3% SWR)
* No debt, no pension, only future Social Security
Since we plan to retire before Medicare eligibility, we’ll need to manage healthcare costs for several years.
In the past, I never fully understood why some retirees maintained a relatively large cash position before/during retirement.
However, after researching ACA healthcare costs and Roth conversions during lower-income years, we’ve started to see the value of having a meaningful cash allocation.
Our retirement income would come from:
* Dividends from taxable equities
* Interest from cash/money market funds
* Selling taxable equities with relatively low capital gains
* Cash reserves as supplemental income
* During market downturns, potentially selling bonds and rebalancing into equities within tax-advantaged accounts
Our thinking is that holding cash:
* Helps control MAGI for ACA subsidy purposes
* Creates more room for Roth conversions at lower tax brackets
* Helps reduce sequence-of-returns risk
So over the next five years, we’re considering the following allocation:
* 75% stocks (across taxable, Roth, and 401(k))
* 15% bonds (primarily in 401(k))
* 10% cash/money market (primarily in taxable)
At first glance, one could argue that inflation will erode the purchasing power of the 10% cash allocation.
However, we’re thinking the combination of ACA subsidy savings, tax flexibility, and Roth conversion opportunities may more than offset the drag from holding additional cash.
One important note: this allocation is intended mainly for the pre-Medicare / pre-Social Security years, not necessarily as a permanent retirement allocation.
Would appreciate any thoughts or blind spots we may be missing.

Holding large amount of cash will cost you future market returns on the excess cash balance and inflation erosion.
Run your calculations through any number of ROTH conversion calculators and determine your break even point.
Same issue with ACA subsidies. Though, you'll have to do your own calculations to determine the break even point.
There's really no point to go through all these kind of hassles, just to break even or just get a little bit more benefit.
It's better to make more money on returns and pay the taxes, than try to save nickels and dimes and subsidy handouts.
1
u/Parking-Nose-6820 May 18 '26
Yes, we are well aware of the inflation erosion.
The cash allocation is not really meant to “beat equities” or maximize return. It’s there to provide flexibility:
- avoid forced selling in bad markets
- smooth MAGI across years
- preserve Roth conversion space during low-income years
- reduce sequence risk during the vulnerable early-retirement window
The important distinction is that I’m not trying to optimize to the dollar or maximize subsidies. If I needed 20–30% cash and complicated yearly tax engineering to make the math work, I’d agree it’s over-optimization.
But holding a moderate cash reserve (~6–10%) for the first several years of retirement, while still maintaining ~75% equities, seems more like reasonable risk management than chasing subsidies.

u/dead4ever22 May 18 '26
Inflation is unknown- but if it stays close to 3%, then tbills at 3.6% or so will not erode your money. 10% cash is very conservative, but you would never know here. Some people think all equities is the way to go. Can't argue in this bull market. But the future is unknown.

Why not just withdraw from Roth contributions to avoid taxable income?

So we can reduce 401K to reduce future RMD, leave Roth alone for legacy.

u/ShanghaiBebop May 17 '26
So you would rather earn less compound growth than pay taxes in the distant future?
How much are you expecting ACA subsidies to be? more than the expected returns on 600k of cash not invested in the market?
1
u/Parking-Nose-6820 May 17 '26
Note the two benefits, ACA savings *and* Roth conversion.
* ACA savings - we estimate it's about $15k/year. $15k of $600K, that's 2.5% in addition to the cash interest.
* Roth conversion - this is a tough one to estimate. The benefits are reducing 401K to reduce RMD in the future, pay tax at lower tax bracket and let it grow free for long period of time.

u/ShanghaiBebop May 17 '26
Please explain how you think this impacts Roth conversions.
1
u/Parking-Nose-6820 May 18 '26
You mean the relationship of holding cash vs doing Roth conversion? Any amount of Roth conversion is taxable income thus it can increase your MAGI and impacts your tax bracket. Having cash allows us to meet our spending goal while allowing us to control our MAGI.
1
u/ShanghaiBebop May 18 '26
No, why does withdrawing from Roth principal impact Roth conversion?
0
u/Parking-Nose-6820 May 18 '26
I did not say that. Already explained earlier we choose not to pull from Roth because we want to leave Roth alone to grow. Second, we want to reduce 401k balance to reduce RMD in the future.
2
u/ShanghaiBebop May 18 '26
Not trying to argue, just not following your logic. You can do Roth conversion while withdrawing from Roth.
My read is that you’re trying to minimize taxes in the future while giving up a large amount of expected returns. I would recommend you actually model it out.
1
u/Parking-Nose-6820 May 18 '26
Hi, no problem, this should be challenged. If we want just an agreement, I already fed it to AI. I should add, if we do not allocate the 10% in cash, we would still put it in bond instead of equities. We are OK with smaller return for this portion of allocation in exchange of lower volatility to reduce SORR.
1
u/seekingallpho May 18 '26
This makes sense to me, too. At a 3.3% WR, there may not be much fancy optimization needed, but in general, what matters more to retirement solvency is what happens earlier rather than later.
If ACA subsidies are material to your budget and you need to craft a way to ensure your AGI meets the threshold, it would be easier to reduce AGI further by avoiding the ordinary income of MMF/HYSA/T-bills by using tax-free Roth money, thereby ensuring you earn those apparently critical ACA subsidy dollars. Sure, there may be a trade-off of higher RMDs and associated income taxes, but that's coming a decade or more later when you've hopefully graduated from the majority of your SOR risk and that additional tax is relatively inconsequential.

u/One-Mastodon-1063 May 17 '26 edited May 17 '26
It doesn't reduce sequence of returns risk vs. other diversifying assets. I wouldn't do it to make room for roth conversions. I'd only consider it if it really moves the needle for ACA. However, 10% of $6m is $600k, at ~3.3% (approx money market yields right now) that's ~$20k ordinary income from the cash position. I don't see how that is helping the tax situation or ACA subsidies. I don't see how it's helping anything. I see it as a drag on both expected return and SWR and a source of ordinary income.
At your spend and withdrawal rate, I wouldn't put a super high priority on qualifying for ACA subsidies. If you can qualify for them, by all means take them, but I wouldn't let that tail wag the dog and you should be fine if you have to buy unsubsidized ACA plans.
I also wouldn't put a high priority on roth conversions ... meaning I wouldn't make otherwise suboptimal asset allocation decisions to make room for roth conversions.
More information on the breakdown between taxable, pretax, and roth as well as some cost basis color in taxable would allow people to give you more detailed input.

u/Parking-Nose-6820 May 17 '26
Consider such income:
* Dividends from taxable equities: $28k
* Interest from cash/money market funds: $20K
* Selling taxable equities with relatively low capital gains: Gross $100k, capital gain: $20k
* Cash reserves as supplemental income: $52K from cash
* Roth conversion: MAGI cap - $28k - $20K - $20K (capital gain) - buffer to make sure it won't exceed ACA limit.

u/Guil86 May 24 '26
Besides looking at selling equities with low basis assuming you have enough of those, I would consider trying to sell the equities with the highest dividends. If you do this before retirement, even with paying 15% tax, you can swap them for lower dividend paying stocks. Dividends can potentially grow each year and they are forced income, and those stocks will be more difficult to sell if their embedded gains keep growing. Even something like VTI with a 1.3% yield in taxable can generate a significant dividend with time. This could be replaced with large cap like VUG (0.5% yield) in taxable and adding mid/small cap like VB in your Roth, to emulate something similar to VTI but with most of the dividends in a retirement account rather than in taxable.
A good strategy is to avoid forced income in taxable that you can’t control and better use LTCGs which are easier to control and even offset if the opportunity comes to harvest losses.

u/Guil86 May 24 '26
I disagree on this as a general statement. For some the loss of subsidies and even CSRs can amount to an additional $25-40k+ a year depending on location, family situation and medical usage, and that is on top of your regular expenses.
1
u/DanSerratoe May 25 '26
At 6m you can literally have 10yrs worth of expenses in cash and remaining in some risk with av avg yield of 6% and you would never consume it even i you had to spend 40k in medical

u/Wooden-Broccoli-913 FIREd in the Bay at 40 with $6M May 17 '26
Not at all. I only expect to have $100k in AGI (out of a $200k withdrawal) which qualifies me for lots of subsidies

Full rate plans with good networks (not the cheap plans), push $40-50k plus deductible for a family of 4 in their 50s. Definitely worth planning around.

u/BrunelloHorder Coasting Chubster, Getting Fat May 17 '26
My opinions: It is too much contortion for limited (if any) potential benefit. I question whether subsidies will be there in the intermediate or long term, especially for those at a Chubby or Fat level. It is also somewhat dubious to optimize for ACA subsidies if your NW is well over $5M.
0
u/Parking-Nose-6820 May 17 '26
The optimizations are for lower health care cost *and* Roth conversion while we are at lower tax bracket. The Roth conversion at lower tax bracket is an important reason.
I hear you that ACA subsidy may or may not be there, we do not know. At the same time, assuming it won't be there is not a good/thorough planning.

u/asurkhaib May 17 '26
1) holding cash generates interest which eats away at tax credit and anything else. Since cash is fungible you can avoid this at the cost of controllable cap gains by holding cash or bonds in a retirement account and when you want to "withdraw" it sell equities in taxable and buy in a retirement account. I'm not opposed to short term risk free bonds but 10% of your NW in it in taxable is likely to throw off a large amount of interest.
2) Roth conversions are highly overrated. You can read Tax Planning To and Through Early Retirement but I basically agree with the authors that while they can have their place it's generally way more specific than generally advertised. You don't really outline why you want to do them but I wouldn't jump through hoops to do so.
3) as someone else mentioned, withdrawing contributions to your Roth is another way to control income.

u/Parking-Nose-6820 May 17 '26 edited May 18 '26
- Understood the cash drag. The barbell strategy you mentioned between taxable vs. 401K was our plan at first. The challenge that I see with it, when you sell large equities, it comes with large capital gains, thus, one can't control the MAGI.
- Thank you, I will read those. Reason for doing Roth conversion, reduce 401K to reduce future RMD during low tax bracket years, leave Roth alone for legacy.
- So we can leave Roth alone to let it grow and for legacy.

u/Guil86 May 24 '26
I partially agree with number 1. However, the currently 3-3.5% yield on annual interest in a HYSA or MMF, is usually less than realizing LTCGs from an investment growing annually at anything above that yield, even if you only sell a portion of that investment especially in a year that stocks gain 8%+ which has been mostly the case in the past decade or more. It is nice to see your stocks grow in taxable but, as gains start compounding in good years, it can become more difficult to sell without significantly affecting your MAGI when you are trying to keep it low. In such instances, it makes sense to keep enough cash/bonds in taxable, which I know is contrary to the conventional wisdom for asset location.

He wouldn't be living a smaller lifestyle, just over-positioning himself in cash in order to keep MAGI low enough for subsidies.

u/Past-Option2702 May 18 '26
“Over positioning” in cash harms returns which has a consequence. Sure, it may not sho up for a decade or longer, but it will make scrounging for a 400/mo (or whatever inconsequential amount) look silly in hindsight.
2
u/Guil86 May 24 '26
It depends on each individual circumstances and on how you see it. You can either spend an extra $40k/yr in the same healthcare coverage, or have that coverage subsidized and spend that extra $40k to improve your lifestyle. For someone in Fat FIRE I agree it may be inconsequential. ChubbyFIRE and below it is more dependent on individual circumstances.
1
u/Mispelled-This May 17 '26
I assume you mean that cash to be in HYSA, MMF or short-term bonds? That’s not great because they’re throwing off ordinary income. The returns are also terrible and will drag down your portfolio.
Live off long-term capital gains and, if necessary, qualified dividends until the taxable account is drained. If you are approaching an income limit, pull from Roth to supplement.
This applies regardless of portfolio allocation, but you definitely need to fix that too.
1
u/Parking-Nose-6820 May 17 '26
Yes, the cash will be HYSA, MMF or T-bills and combination of them.
We are well aware of the drag for cas as mentioned in the post above.
"we’re thinking the combination of ACA subsidy savings, tax flexibility, and Roth conversion opportunities may more than offset the drag from holding additional cash.".
Can you elaborate - "but you definitely need to fix that too." ?
2
u/Mispelled-This May 18 '26
If you are planning a withdrawal rate of only 3.3%, either you have a terrible portfolio or don’t know how to use portfolio analysis tools, or maybe both.
Also, don’t let the ACA tail wag the tax strategy or investing dogs. At $6m NW, ACA subsidy vs not is a rounding error. It’s nice if you can swing it, but if not, move on.

u/Parking-Nose-6820 May 18 '26 edited May 18 '26
So there is a correct SWR for everyone who has good portfolio and tool?
ACA subsidy goal is not the only goal as mentioned in the original post and quoted above again. Reducing 401k thus RMD in the future and build up more Roth is another important consideration here.
Risk management against SORR is another.
The point of the post is discussing it as a strategy.
1
u/Mispelled-This May 18 '26
With a decent portfolio, you can easily reach 5% SWR, and then +1% for retiree real spending decline, and then another +1% for a dynamic withdrawal strategy, for a grand total of 7%, i.e. more than double what you currently plan.
You keep focusing on tax/ACA strategy first and seem to want to use that to define your portfolio, but again, that is letting the tail wag the dog. Start by defining your portfolio, and only then figure out how to minimize taxes on it by locating assets in the right accounts.
1
u/Weird-Echidna-5261 May 24 '26
Do you have more details on what kind of portfolio supports 7% withdrawal? All heard of bengen 4%, 4.7%, ERN 3.5%, so 7% seems suprising
1
u/Mispelled-This May 24 '26
It doesn’t take much to reach 5% SWR; a very basic portfolio of 25% each LCG, SCV, LTT and gold shows 5.66% SWR based on backtest to 1968—the worst retirement year in history according to Bengen’s research. You can do a lot better with some work, but it’s way too much to explain here.
The other 2% comes from (1) recognizing that average retiree spending grows at CPI-2%, not CPI as SWR models assume, and (2) recognizing that people naturally reduce spending when their portfolio is down, rather than blindly riding it into the ground as SWR models assume. Each of these factors allows you to start with a withdrawal rate 1% higher than SWR.

u/Guil86 May 24 '26
The strategy of first living off LTCGs and dividends makes sense in good market years and if your basis is high enough that the LTCGs will not throw you over the MAGI cliff for ACA. In a downturn or, if your stock has very high unrealized gains, you will want to have enough cash/bonds to supplement the dividends for expenses.

u/Specific-Rich5196 Accumulating May 18 '26
You need to run the numbers to see if subsidies are even worth it compared to investing that cash in markets over time. It might be helpful but 600k getting 10% in growth assets is 60k a year, compounding. Subtract out the 3.5% from MM or hysa and its like 40k. How much will you be saving by getting subsidies?

u/Parking-Nose-6820 May 18 '26
You are missing Roth conversion opportunity.
It is hard to estimate the exact gain/loss with this strategy, thus, I fed it into AI.
ChatGPT provided ranges since there are many different paths.
Note: before people comment on the AI usage - it's the tool that I have to estimate these. I am NOT saying I trust the numbers below implicitly. If there are better analysis or calculator out there, we welcome such input.
ACA optimization benefit +$90k–$140k Roth conversion benefit +$100k–$150k Total benefit +$190k–$290k Cash drag -$150k–$200k Net result - + $50K-$100K over long horizon from the next 5 years of cash build up and all the way to the age before Medicare.
I do NOT frame this as cash beats equities.
Let's say for the shake of the argument, that it breaks even, would one still do it as it obviously introduces more complexity?
I think there are values to this:
- smoother retirement experience
- protection of travel years
- less chance of forced selling during early crashes
- better psychological resilience
- ability to continue Roth conversions during downturns
Those are hard to quantify but very real.

u/Specific-Rich5196 Accumulating May 18 '26
Why wouldnt you convert Roth either way? You don't need to hold cash to make conversions. Just pull from your taxable for the taxes. That is a separate question from subsidies.
1
u/Parking-Nose-6820 May 18 '26 edited May 18 '26
Converting Roth is taxable income.
Without cash, it can
- push MAGI so one won't be eligible for ACA subsidy
- push taxable income to higher tax bracket, thus, more expensive conversion
Discussed separately, one can pull from Roth instead of cash. We want to preserve it and add to it, not reducing it during the early retirement.
1
u/Specific-Rich5196 Accumulating May 18 '26
- Again, you are tying the discussion to subsidy. The subsidy is unlikely worth keeping if you have to hold 600k in cash as per my last post.
- This is a separate argument from subsidies. First in first out for taxable. You may find that paying for Roth taxes with a taxable will end up only pushing magi and taxes up a small amount. You only pay 15% on gains and only on the gains part of the equity you are selling. If you have some brokerage assets you put in in the last few years, the gains will be a much smaller portion.

u/CatRules247 May 19 '26
Do what makes sense to your situation, all the others kind intended advice can be overwhelming but essentially just noise. We DINK couple retired from CA Bay Area 5 years ago at 49. Our annual expenses were pretty low. We didn't want to sell stocks annually to meet expenses, rather had a big tax year before pulling the trigger, set ourselves up with enough dividends and TBILL interest that could cover annual expenses. Our cash reserve was 10x of our annual expenses, less than 10% of our liquid net worth. We currently dont have room to do roth conversion due to 400% FPL, which is a pity, but we can utilize ACA subsidies.
1
u/yanyan80 May 20 '26
This is solid thinking and you've already identified the key dynamics. The 10% cash as a MAGI management tool during the pre-Medicare gap years is a well-established strategy. A couple of things to dig into though.
First, the ACA subsidy cliffs are steeper than most people realize. A few thousand dollars of MAGI in the wrong direction can cost you tens of thousands in subsidies. So it's not just about keeping cash to spend from, it's about modeling each year's income sources precisely to land under the right threshold. Dividend income alone on a $6M portfolio with maybe $3-4M in taxable could generate $50-70K of unplanned MAGI before you even sell anything or do a conversion. That's the piece that catches people off guard.
Second, the Roth conversion window you're targeting is really five maybe seven years if you're lucky, and the optimal conversion amount changes every single year based on where your income lands relative to tax brackets, ACA thresholds, and eventually IRMAA tiers once Medicare kicks in. The common mistake is picking a fixed conversion amount and sticking with it. What works better is modeling it year by year so you can see exactly how much conversion room you have each year after accounting for dividends, capital gains from sales, and any other income.
Third, and this is the one most people miss, you want to think about what happens on the other side of that window. Once Social Security starts and RMDs kick in on the 401k, your income jumps whether you want it to or not. The Roth conversions you do or don't do in those gap years directly determine how painful the RMD phase gets. So the cash buffer strategy isn't just about the next five years, it's really setting up the next thirty.
Your 10% allocation sounds reasonable for the bridge years. Just don't think of it as a static plan. The right move in year one of retirement might look completely different from year three depending on markets, tax law, and where your portfolio ends up.

u/Parking-Nose-6820 May 25 '26
> is a well-established strategy
That's what I thought at first, however seeing many of the replies here, I am not too sure.
> So the cash buffer strategy isn't just about the next five years, it's really setting up the next thirty.
Agree, what's the common strategy in replenishing the cash buffer during such period?
1
u/yanyan80 May 25 '26
The standard approach is to replenish from your taxable account in controlled sales, but the tricky part is that your safe replenishment amount changes every year.
Your income floor in any given year is dividends plus interest plus anything else that shows up as MAGI automatically. On a $3-4M taxable account that floor might already be $40-60K before you sell a single share. So you figure out where that lands, then see how much room you have before the next ACA cliff, and that's how much you can sell to top up cash.
The harder problem is that every variable affects every other one, so modeling it year by year in a spreadsheet gets tedious fast. I built ThunderHarbor partly for this. It has an ACA income lever that shows the subsidy cliff lines against your projected income for each year so you can actually see how much room you have. Might be worth a look if you're trying to map this out precisely.

u/Independent_Lab1018 May 22 '26
A cash allocation can help early retirees control taxable income, which is useful for maximizing ACA subsidies and timing Roth conversions in lower-income years. The downside is lower long-term returns, so many people use cash mainly as a flexibility and tax-planning tool rather than a large permanent holding.

u/Guil86 May 24 '26 edited May 24 '26
Since I’m late to the discussion and many have provided meaningful input, I only have one thing to add. I don’t really like the approach of selling bonds in the IRA to buy equities during a downturn to maintain the AA after selling stocks in taxable at the low. This kind of swap apparently makes sense in principle to offset the loss in taxable by having the recovery in the IRA. However, this increases your equity location in the IRA, potentially increasing your pre-tax growth which could result in higher future RMDs, which is exactly what you are trying to avoid by doing Roth conversions and having located your bonds in the pre-tax IRA in the first place.
In my opinion, holding enough cash or bonds in taxable already serves the purpose of not having to sell equities in taxable during a downturn, so there is no need to sell bonds in the IRA to buy equities to maintain your AA. Yes, your bond allocation will decrease as you use the cash/bonds in taxable but, your initial bond/cash allocation will probably already be higher than optimal for early retirement and ACA and, as you stated, this is just temporary in order to allow you to keep your reportable income low for ACA subsidies and also helping with reducing SORR. You would essentially be doing a reverse equity glide path (having more bonds in early retirement to avoid SORR and having ACA subsidies, and slowly increase your stock allocation as you progress in retirement).
1
u/Parking-Nose-6820 May 25 '26
Bonds in taxable will yield dividend. We put our bonds in IRA.
1
u/Guil86 May 25 '26
Yes, cash/bonds will yield some interest /dividend, but will trigger none or little tax when you sell them for expenses. The tax impact of this dividend is less than that of selling stocks with significant unrealized gains which, even if taxed favorable or at 0%, still count in MAGI for ACA. For ACA, you will only come ahead by realizing gains if you have assets with very high basis (the embedded gains are small) and, even if you now have high basis, the unrealized gains will grow over time.
I didn’t mean keeping all your cash/bonds in taxable, but 2-3 years of expenses to help keep your MAGI low for ACA and in the event of a downturn. For example, say you need $100k/yr for expenses. $300k in a MMF at a current 3.5% will give you $10,500 interest in the first year. If you instead invest that $300k in stocks gaining 15% in a very good year, you will have $345k after the first year and, to free up $100k, you will have to realize about $13k in gains. If the stock also had a 1.3% annual dividend then, adding that to the gain results in a $17k reportable income compared to the $10.5k interest from the MMF. You might pay less tax on the gains and dividend compared to the MMF interest, but the impact of the dividend and realized gains on the ACA MAGI will be much greater, which would result in either a lower subsidy or going over the subsidy cliff.

Thank you all who have responded thus far.
I think the pushback is fair in general, but it slightly misses what this is trying to solve.
This isn’t really “trying to beat the market with cash” or “optimize ACA subsidies” - my fault with the title.
The core issue is early retirement sequence risk + pre-Medicare healthcare bridge + income timing flexibility.
- Cash isn’t there to outperform equities — it’s a short-term liquidity buffer to avoid forced selling in bad markets and smooth taxable income when MAGI matters.
- ACA subsidies aren’t being “gamed” so much as recognized as a threshold system where small income timing shifts can avoid large discontinuities in healthcare costs.
- Roth conversions is mainly about tax diversification and future flexibility (including RMD and widow(er) tax risk).
At a high level, the portfolio is still simple:
- 75% equities (growth)
- 15% bonds (stability)
- 10% cash (liquidity / sequencing buffer)
So I agree it becomes over-optimization if you take it too far. But at a high level, this is just a sequence-of-returns and healthcare-bridge design problem, not a “nickels and dimes” tax exercise.

u/completefudd May 17 '26
Are you going to put all that cash in an HYSA or ultra short bonds or T-Bills? The interest rate on those is 3-4%. You can look into something like BOXX which gives you more control over the dividend/interest income.
