About Coast FIRE Calculator

Empowering everyday people to harness compound interest and design lives of autonomy, purpose, and balance.

Why We Built This Tool

The traditional retirement paradigm asks you to defer living for 40+ years in exchange for freedom at age 65. The FIRE (Financial Independence, Retire Early) movement flipped that script, but often creates extreme frugality burnout.

Coast FIRE offers the sweet spot: front-load your investments in your 20s and 30s until compound interest guarantees your retirement nest egg. From that point on, you only need to earn enough to pay your day-to-day bills. No more retirement savings required.
