How Long Will $1 Million Last in Retirement? (And Is It Enough?)

By the Can I Retire Calc team · Last updated October 30, 2026 · General education, not personal advice

"Is $1 million enough to retire?" is one of the most common retirement questions, and the honest answer is: it depends on how much you spend, how long you live, what your investments earn and what other income you have. The good news is that you can work it out with simple math. This guide shows how long $1 million can last under different assumptions.

The quick answer

A common rule of thumb says you can withdraw about 4% of your savings in the first year of retirement and adjust for inflation afterward. On $1,000,000, that is $40,000 a year, or about $3,333 a month, before taxes. If that, plus Social Security and any pension, covers your spending, $1 million may be enough. If you want to spend much more, it may run out within your lifetime. Read more about the 4% rule and its limits.

How many years will $1 million last?

The table below shows roughly how long $1,000,000 lasts if you withdraw a fixed amount each month in today's dollars. Withdrawals rise with inflation so your buying power stays the same. It assumes a steady yearly return before inflation, 2.5% inflation, and no taxes.

What the table tells us

Is $1 million enough for you? Four questions

  1. How much will you spend each month? Start with your current spending and adjust for expenses that will end or begin, such as a mortgage, commuting, healthcare and travel.
  2. How much guaranteed income will you have? Social Security and pensions reduce how much you must take from savings. For example, if you spend $5,000 a month and receive $2,000 from Social Security, you only need $3,000 a month from savings, and the table shows that $1 million at a moderate return can cover that for several decades.
  3. How long do you need it to last? Many people plan to age 90 or 95, because living longer than planned is a bigger risk than leaving money behind.
  4. What are your taxes and healthcare costs? Withdrawals from traditional 401(k)s and IRAs are generally taxed, and healthcare can be a major cost, especially before Medicare begins at 65. See your options before 65.

How to stretch your money

  1. Delay Social Security to receive a larger monthly benefit for life. See how claiming age matters.
  2. Keep a flexible budget. Cutting spending a little after a bad market year helps a great deal. Learn why early bad years matter most.
  3. Work part-time for a few years to reduce early withdrawals.
  4. Watch fees. A 1% yearly fee can reduce a long-term balance by about a quarter.

Key takeawaysThere is no single answer to whether $1 million is enough. It is enough for some people and not for others, depending on spending, guaranteed income, retirement age, taxes and healthcare. Use the table as a guide and test your own plan with cautious assumptions.

Frequently asked questions

How long will $1 million last if I withdraw $4,000 a month?

Roughly 25 years at a 4% return, 29 years at 5% and 36 years at 6%, assuming 2.5% inflation, steady returns and no taxes. Real markets vary, so actual results will differ.

Can I retire at 55 with $1 million?

Possibly, if your spending is modest, but you would need the money to last 35 to 40 years and would have years before Social Security and Medicare. A lower withdrawal rate, a cash cushion and a plan for health insurance are important. Read about retiring before 65

At a 4% withdrawal rate, about $3,333 a month before taxes in the first year, adjusted for inflation afterward. A more cautious 3.5% is about $2,917 a month. Social Security or a pension would come on top of that.
