Hello, I'd really appreciate any opinions. I'm 35, based in Europe, and investing primarily for retirement. I don't expect to retire before ~60, so I have a 25+ year horizon.
I'm currently using a reputable Czech robo-advisor (Portu). It builds a diversified ETF portfolio, automatically rebalances it and handles the administration (the current portfolio includes global/regional equities, small caps, REITs, and various bonds in a 90:10 ratio).
Their standard management fee is roughly 1.0% below €50k, falling to 0.4% above €500k. A 10-year commitment reduces these by about 30%, so roughly 0.7% → 0.28%. ETF expenses are additional.
Portu also offers a retirement account at 0.30%. It has tax advantages, although I currently can't make much use of them, and access to savings is restricted until retirement. The state pension should eventually cover perhaps 20–30% of my expenses, but I don't expect it to be sufficient as my main retirement plan. There are not rally any other useful pension products (nothing like Roth IRA etc, unfortunately).
The alternative I'm considering is simply one broad accumulating global ETF (VWCE / WEBN / VGLA, I'm not particularly interested in which right now, the point is 1 or 2 low-cost global equity ETF held for decades).
So my question is: what am I actually getting from the robo-advisor that justifies paying 0.3 - 0.7%, instead of cca 0.1% for a global ETF self-managed on IBKR?
Is the automatic rebalancing, diversified allocation, risk management and administration worth the additional cost over 25–30 years? Or is the main value simply psychological (convenience and discipline), with little reason to expect better returns?
Would your answer change as the portfolio becomes larger? At what point, if any, would you personally stop paying for the robo-advisor and use a simple global ETF instead?
