What is CAPE Withdrawal?
A strategy that looks at how expensive the stock market is today to tell you how much you can safely spend tomorrow.
Valuation Matters
The Shiller CAPE (Cyclically Adjusted Price-to-Earnings) ratio is a measure of whether the stock market is cheap or expensive relative to historical earnings.
The Logic: When the market is expensive (high CAPE), future returns are likely to be lower, so you should withdraw less. When the market is cheap (low CAPE), future returns are likely to be higher, so you can safely withdraw more.
How It Works
High CAPE (Expensive Market)
Example: CAPE > 30.
Action: Lower your withdrawal rate (e.g., to 3% or 3.5%).
Low CAPE (Cheap Market)
Example: CAPE < 15.
Action: Consider a higher withdrawal rate (e.g., 4% to 4.5%).
The Formula
A simple rule derived from CAPE is:
Withdrawal Rate = CAEY + 1.5%
*CAEY = Cyclically Adjusted Earnings Yield (1 / CAPE).
Pros and Cons
The Upside
- Data-Driven: It uses objective market valuation data rather than guessing.
- Preservation: It's extremely effective at preserving capital because it reacts to valuation risks before they fully materialize.
- Responsive: Helps you avoid overspending during market bubbles.
The Downside
- Volatile Income: Your allowable spending can fluctuate significantly from year to year as market valuations change.
- Too Conservative? In prolonged bull markets (like the 2010s), it might suggest uncomfortably low withdrawal rates, causing you to underspend and die with too much money.
