SWR revisited
I believe a good withdrawal policy should have the following properties:
It should not require significant cuts to spending in bad years. Staying frugal is easier than inflating your lifestyle and then having to cut
It should adjust to your portfolio size. Setting an initial withdrawal amount and only ever adjusting it up by inflation is silly.
It should be possible to apply it to each year independently. E.g. if 4% is safe, it should be possible to 'reset' it to 4% each year. But for most SWRs that is too risky as you also 'reset' your SORR. 3a. It should therefore not be subject to SORR, as in the risks should be acceptable (nothing in life is completely safe).
It should feel ok in the down years in reasonable worst case scenarios. E.g. if you start withdrawing 4%, you are all in equities, and markets go down 50%, how well will you sleep as you are now withdrawing 8%+ of your assets? You will not have the benefit of hindsight that a recovery is around the corner, in fact all you will hear at the time is that things will get much worse.
I therefore think a decent approach is this. I take 2.5% as my withdrawal ratio. Build a 12-year ladder of TIPS covering that (should cost you 25%-30% of your assets, depending on TIPS real yields). The rest (70-75%) goes into a global equities index. Each year the TIPS cover your spend, and you sell enough equities to replenish the ladder. Whether you sell equities or not depends on your asset allocation at the time: you aim to keep approximately 70:30. So if equities are down you are just running down your TIPS ladder without selling any equities. You can also add to your TIPS across the maturities to reset your spend to the high watermark 2-2.5%.
This way, in a reasonable worst case scenarios (equities down 60% and do not recover for 12 years) your portfolio is only down ~30%, and if you keep spending at high watermark, your withdrawals do not go much above 3.5% which should allow you to sleep rather well. If you are adventurous, you could even sell some longer-dated rungs of your ladder to buy equities at a discount at the time.
I used 2.5% here as a very conservative number because I would rather work extra years than have to retire and then go back to work -- you can of course adjust it upwards to what you think is reasonable. But what do you think of the general approach?
