This calculator estimates your FIRE number, the savings that can cover your annual expenses at a chosen withdrawal rate, and how many years of monthly saving it takes to get there. Enter your expenses, savings, contribution, and expected return to see a target and a timeline. Use it to sanity-check an early-retirement plan.
How this is calculated
The FIRE number is annual expenses divided by the withdrawal rate, so a 4 percent rate gives the well-known 25 times expenses. The timeline grows your current savings plus monthly contributions at the expected return, month by month, until the balance reaches the target.

FAQ
- What is the 4 percent rule?
- It is a guideline that a portfolio can sustain annual withdrawals of about 4 percent of its starting value, adjusted for inflation, for roughly 30 years. A 4 percent rate gives a FIRE number of 25 times your annual expenses.
- What withdrawal rate should I use?
- Many plans use 3.5 to 4 percent. A lower rate is more conservative and needs a larger nest egg, while a higher rate needs less but carries more risk of running short.
- Does this account for inflation?
- The expected return you enter should be a real, after-inflation return if you want the timeline in today dollars. The withdrawal-rate rule already assumes inflation-adjusted spending.
