Coast FIRE Runway & Pitfall Simulator

Saved principal one hundred forty-five thousand times seven percent gives ten thousand one hundred fifty annual growth before additions. Bars compare principal and annual growth at point zero zero three pixels per dollar. Constant return is a scenario assumption rather than a guaranteed investment result. At the initial below-coast balance, source applies growth to starting principal and then adds twelve thousand annual savings, yielding one hundred sixty-seven thousand one hundred fifty. Bars compare growth-only balance one hundred fifty-five thousand one hundred fifty and balance after contribution at point zero zero three pixels per dollar. Timing matters; savings do not earn the first year's growth in this recurrence. Saved target sixty-two less current thirty-two gives thirty years. Bars share zero at ten pixels per age year. Coast criterion tests whether accumulated balance times one point zero seven raised to remaining years reaches target one million five hundred thousand; contributions stop when criterion passes. Complete raw schedule/parameters/reset/resize preserved. Inflation and stress scenarios do not validate retirement sufficiency.
