Can I Coast FIRE on $500k income? (married)
At 35 with $660,000 already in retirement accounts, you've crossed the threshold most people spend their entire career chasing — your math says you can stop contributing today and still retire with more money than 99% of Americans ever accumulate.

Here's the counter-intuitive part: your $660,000 in retirement savings, left completely alone for 30 years, is projected to grow to $35M by age 65 — meaning the $60,000 per year you'd stop contributing is essentially noise against the compounding already in motion, and that engine funds $18,204 every single month in retirement across a 25-year coverage window.
With $660,000 in retirement accounts and zero new contributions, the engine projects $35M net worth at age 65 on $18,204/mo of retirement spending (≈ $7,500/mo in today’s dollars). You'd free up ~$5,000/mo but give up $3.6M in retirement wealth compared to keeping current contributions.
| Scenario | Strategy | Retire NW | Retire SWR/mo | Coverage | Retirement Feasible |
|---|---|---|---|---|---|
| Full save | Keep saving (current plan) | $38,359,813 ($16M in today's dollars) | $127,866 | 25 yrs | Secure |
| 50% save | Half contributions | $38,359,813 ($16M in today's dollars) | $127,866 | 25 yrs | Secure |
| Coast | Coast — stop all contributions | $34,792,224 ($14M in today's dollars) | $115,974 | 25 yrs | Secure |
Coasting assumes markets deliver historical returns. A prolonged downturn early on could derail the math.
