At this contribution rate, you're not projected to reach Coast FIRE before age 65 — you'd still be actively saving for retirement right up to that age, which is a normal FIRE trajectory, just not a “coasting” one.

Assumes you keep contributing $500/mo. Blue = already coasted by that age.

Estimate only. All figures are in today's dollars — the return rate should be a real (after-inflation) rate, and retirement spending is assumed constant in real terms, which is the standard simplification most FIRE calculators use to avoid separately modeling inflation. Assumes a constant return every year (no market volatility), doesn't account for Social Security, and doesn't model taxes on withdrawals. Not financial advice.
