After a lot of varied research, investigations and thinking, I think I'm settling on a withdrawal strategy that works for my lifestyle and expenses.
I'm calling it the "waterfall" for lack of a better term.
The basic structure is like this:
1. At the top of the waterfall: diversified stocks portfolio. The most churn and volatility in the short-term, but the best bet on long-term real returns (or at least, capital preservation). This one has most of my money – around 70%, though it will fluctuate in the short-term.
2. In the middle of the waterfall: inflation-linked bonds. These are in a ladder, mostly concentrated in the next 5-10 years, but with a little at the long end, to take advantage of convexity. These bonds, including coupon, are enough to cover my living expenses adjusted for CPI. These are around 25% of the portfolio.
3. At the bottom of the waterfall: high-interest savings account. This is enough to cover me until the next inflation-linked bond in the ladder matures, minus the inflation-linked bond coupon income, which I already get paid quarterly from my existing bond holdings, so no need to hold it in savings. Currently around 2 years of living expenses, with a little padding for emergencies. These are around 5% of the portfolio.
How I plan to manage it is something like this:
Every quarter, or after a stretch of above-average stock performance, I'll sell a small percentage of the stocks, enough to cover one quarter of living expenses.
- If stocks are up since the last sale, I'll draw down ~3-4% of the cost basis, plus personal realised inflation (as measured by my budget, which I will do monthly, based on examining my bank statements).
- If stocks are down since the last sale, I'll draw down ~2-3% of the cost basis, plus personal realised inflation (measured similar to the above, but perhaps factoring in some budget cuts in response to the lower returns)
By "personal realised inflation", I mean the lower of CPI or personal spending, compounded over the time since early retirement. For example, if I retired in 2023, and inflation was 3% in 2023 and 4% in 2025, then the inflation adjustment will be 1.03 x 1.04 = 1.0712 = 7.12%. So in that case, I will withdraw 7.12% of 1 million or $71,200. Well actually, a quarter of that, so really 17,800. The goal is to keep my living expenses at or below CPI. Of course this might be tricky in the short term, but the idea is to try and keep it this way as much as possible over the long-term.
With the one quarter of living expenses withdrawn, I will invest it immediately into the next step on the inflation-linked bond ladder, such that it covers that future quarter's living expenses after CPI.
For example, suppose the year is 2026 and we're in January. If my next bond is maturing in 2036, and has enough to fund 2 quarters of living expenses (6 months) then I will top it up to 3 quarters (9 months) by buying additional units of that bond.
In this way, there will always be a buffer of 5-10 years between my stock valuation and my living expenses. This buys me time to shift my income, location, lifestyle, etc. in any way necessary to deal with any long-term fluctuations.

Note: I'm motivated to write this mainly to get my thoughts out clearly so I can analyse them, but also to get feedback from anyone else's who's interested/curious. This is not intended to sway anyone else's withdrawal strategy. There are pros and cons to all strategies. This is just what I feel will work best for me and my own needs and personality.
