The rule of thumb

Your number is spending × 25

The 4% rule says you can withdraw about 4% of your portfolio each year and expect it to last roughly 30 years. Flip it around: to fund $50,000 a year you need about $1.25 million saved. FIRE fans just shrink the year.

  1. Project savings with your current income and rate.
  2. Compare against the 4% rule target.
  3. Add Social Security to see the gap shrink.
  4. Switch FIRE to find your true independence age.

Run the numbers before you hand in your notice

If you're weighing a job change, a career break, or early retirement, you need a reality check on your timeline. This calculator applies the 4% rule to your actual savings rate, current balance, and expected returns so you can see whether your target retirement age is feasible. Toggle FIRE mode to test aggressive savings scenarios, or include Social Security to see how benefits shift your required nest egg. It's built for anyone who wants a concrete answer, not a vague guideline, about when work becomes optional.

Retirement questions

What is the 4% rule?

The 4% rule holds that withdrawing 4% of your portfolio in year one, then adjusting for inflation, historically kept a diversified portfolio from running out over roughly 30 years. Many planners use 3% for longer or more cautious horizons.

How much do I need to retire at 65?

Multiply your annual retirement spending by 25 (the inverse of 4%). Expenses of $50,000 a year call for about $1.25 million, minus whatever Social Security and pensions will cover.

What does FIRE stand for?

Financial Independence, Retire Early. The goal is to grow savings until annual withdrawals from your nest egg cover your living costs — funded by a high savings rate that shortens the working years needed.

Should I include Social Security in my estimate?

Yes if you expect to be eligible — it replaces part of your spending and shrinks the savings gap. Count it conservatively and only from the age you plan to claim it.
