How Long Will $4 Million Last in Retirement?
Short answer: withdrawing 4% a year ($13,333/month) with 5% returns and 2.5% inflation, $4 Million lasts about 38.5 years. At 5% withdrawals it lasts about 27.4 years. Your spending and returns change that a lot — run your own numbers below.
$4 Million: years it lasts by withdrawal and return
Each cell is how long the balance survives when withdrawals start at the monthly amount shown and then grow 2.5% a year with inflation. "∞" means growth outpaces withdrawals and the balance never runs out.
| Monthly withdrawal | Annual rate | 3% return | 5% return | 7% return |
|---|---|---|---|---|
| $10,000/mo | 3% | 36.5 years | 68.0 years | ∞ |
| $13,350/mo | 4% | 26.8 years | 38.4 years | ∞ |
| $16,650/mo | 5% | 21.2 years | 27.5 years | 46.4 years |
| $20,000/mo | 6% | 17.5 years | 21.4 years | 29.6 years |
| $26,650/mo | 8% | 13.0 years | 15.0 years | 18.1 years |
What $4 Million actually buys you
Retirement math is an income problem, not a lump-sum problem. $4 Million at a 4% withdrawal rate is $159,996 a year. The typical retired worker receives about $1,976 a month from Social Security, so a single person with $4 Million saved is looking at roughly $15,309 a month before tax. A couple with two benefits does materially better.
At $4 million a 3% withdrawal is $10,000 a month and the portfolio still grows in real terms under most assumptions. Running out is no longer a plausible risk; the live questions are estate tax thresholds in states like Oregon and Massachusetts, charitable structure, and Roth conversions before required distributions begin.
Three things that move the answer more than the starting balance
- Withdrawal rate. The gap between 4% and 6% is not "a bit shorter" — in the table above it is often the difference between lasting 30+ years and running dry in the early 20s.
- Sequence of returns. The calculator uses a steady average. Real retirees who hit a bear market in years one through three of retirement fare worse than the average suggests. Keeping one to two years of spending in cash or short-term bonds is the standard defence.
- Inflation. At 2.5% inflation, spending doubles in about 28 years. The calculator raises your withdrawal every year to preserve purchasing power; fixed-dollar withdrawals would last longer on paper but leave you poorer in real terms.
How to make $4 Million last longer
- Delay Social Security. Each year you wait from 62 to 70 raises the benefit roughly 7–8%. Bridging a few years from savings can be worth it if you're healthy.
- Use a flexible withdrawal rule. Cutting spending 10% after a bad year (the "guardrails" approach) adds years of survival in most historical scenarios.
- Mind the tax wrapper. Drawing from taxable accounts first, then traditional, then Roth is the textbook order; it often beats pro-rata withdrawals by a year or two of portfolio life.
- Part-time income. Even $1,000 a month of work in the first five years cuts the withdrawal rate dramatically during the most dangerous sequence-risk window.
Frequently asked questions
Can I retire on $4 Million?
It depends on spending, not the number alone. At a 4% withdrawal rate $4 Million produces about $13,333 a month before tax. Add Social Security (the average retired-worker benefit is about $1,976/month) and compare that total to your real monthly expenses. If expenses are covered with a margin, $4 Million can work; if not, you need lower spending, more income, or a later retirement date.
How much can I withdraw from $4 Million each month?
To make $4 Million last 30 years at 5% average returns and 2.5% inflation, the calculator shows a starting withdrawal of about $15,685 per month, rising with inflation each year. For a 25-year horizon it is about $17,848.
What return should I assume?
A balanced 60/40 portfolio has historically returned roughly 6–8% a year nominal, but sequence risk means early losses hurt more than the average suggests. Most planners test 4–6% for a conservative plan. Use the calculator above to see how sensitive your result is — that sensitivity is the real lesson.
Does this include taxes?
The table assumes no tax. If the money is in a traditional 401(k) or IRA, withdrawals are taxed as ordinary income — enter your expected tax rate in the calculator and it will gross up each withdrawal accordingly. Roth and taxable-brokerage money behave differently.
