What is FIRE?

FIRE — Financial Independence, Retire Early — is the point where your invested savings can cover your living costs indefinitely, so paid work becomes optional. The two levers are how much you invest each year and your FIRE number: annual spending ÷ your safe withdrawal rate (4% → 25×).

FAQ

Does hitting my FIRE number guarantee my money lasts?

No — markets don't rise in a straight line. A single number ignores sequence-of-returns risk. Ember's full planner runs Monte-Carlo and historical simulations so you can see how often your money actually lasts. Open the full planner →

What return should I use?

Use a real (after-inflation) return. A common long-run assumption for a stock-heavy portfolio is 4–6% real; be conservative if unsure.
