Can I Coast FIRE on $500k income? (single)
At 35 with $660,000 already in retirement accounts, you've hit a number most people spend their entire career chasing — and the question isn't whether you can retire, it's whether you even need to keep saving for it.

Your $660,000 in retirement savings, left completely untouched, is projected to compound to $32M by age 65 — meaning the $100,000 in annual contributions you'd stop making are mathematically irrelevant to your retirement outcome. The engine shows 25 years of coverage on a spend of $13,719 per month in future dollars, which means coasting now doesn't shrink your retirement; it just stops you from over-funding one that's already won.
With $660,000 in retirement accounts and zero new contributions, the engine projects $32M net worth at age 65 on $13,719/mo of retirement spending (≈ $5,652/mo in today’s dollars). You'd free up ~$8,333/mo but give up $4.3M in retirement wealth compared to keeping current contributions.
| Scenario | Strategy | Retire NW | Retire SWR/mo | Coverage | Retirement Feasible |
|---|---|---|---|---|---|
| Full save | Keep saving (current plan) | $36,700,589 ($15M in today's dollars) | $122,335 | 25 yrs | Secure |
| 50% save | Half contributions | $36,700,589 ($15M in today's dollars) | $122,335 | 25 yrs | Secure |
| Coast | Coast — stop all contributions | $32,421,664 ($13M in today's dollars) | $108,072 | 25 yrs | Secure |
Coasting assumes markets deliver historical returns. A prolonged downturn early on could derail the math.
