## What it is

- Calculates your Coast FIRE number: the amount you need invested today so that,
  with compound growth alone, it reaches your FIRE/retirement target by your
  retirement age — even if you stop contributing.
- Shows whether you've already hit Coast FIRE, and if not, how far off you are.
- Free, browser-based, no sign-up.

## Key facts

- Coast FIRE differs from full FIRE: at Coast FIRE you can stop *saving* (but keep
  working to cover current expenses) and still retire on schedule.
- Inputs: current age, retirement age, current invested assets, annual return
  (real, inflation-adjusted), and target retirement (FIRE) number.
- Formula: CoastFIRE number = FIRE number / (1 + r)^(years to retirement).
- Related concepts: Barista FIRE, Lean/Fat FIRE, the 4% rule, compound interest.
