A famous rule of thumb for retirement spending — and its caveats.

The '4% rule' is a well-known guideline suggesting you can withdraw about 4% of your retirement portfolio in the first year, then adjust for inflation each year, with a good chance the money lasts about 30 years. It's a starting point, not a guarantee. This is educational information, not advice.

How it works

On a $1,000,000 portfolio, 4% is $40,000 in year one; you'd increase that dollar amount with inflation thereafter. The rule came from historical studies of U.S. stock and bond returns and assumes a diversified portfolio held through ups and downs.

Its limits

The 4% rule is a simplification. Actual safe withdrawal depends on your time horizon, portfolio mix, fees, market conditions at retirement, and flexibility to cut spending in down years. Many planners treat it as a rough anchor and adjust. Talk to a professional for a real plan.

Frequently asked questions

Is the 4% rule guaranteed?

No — it's a historical rule of thumb, not a guarantee. Outcomes vary with markets, fees, and how long you need the money to last.

How big a portfolio do I need?

A rough inverse of the rule: to withdraw $40,000/year at 4%, you'd need about $1,000,000. This is educational information, not personalized advice.
