Coast FIRE Calculator: The Complete Resource Hub for Retirement Math

Coast FIRE Calculator: The Complete Resource Hub

Coast FIRE is one of the most practical milestones in personal finance — the moment your invested portfolio, left alone, will compound to your retirement number by age 65. No more saving required. You can "coast" the rest of the way.

The Formula

Coast Number = Target Retirement / (1 + real_return)^years_to_65

Example: Want $1.25M at 65, currently 35, assuming 7% real return → Coast Number ≈ $164,000 invested today.

Run your own numbers at coastfirecalculator.io.

Why Coast FIRE Matters

Unlike Lean FIRE (extreme frugality forever) or Fat FIRE (massive savings required), Coast FIRE is achievable for normal earners and unlocks optional work without career sabotage.
