Your $132,000 in retirement savings, left untouched for 30 years, is projected to compound to $5.3M by age 65 — enough to fund $6,554 per month in retirement spending for 25 years. The trade-off is real: coasting means forfeiting $11,100 per year in contributions, but the math says your existing balance no longer needs them.
With $132,000 in retirement accounts and zero new contributions, the engine projects $5.3M net worth at age 65 on $6,554/mo of retirement spending (≈ $2,700/mo in today’s dollars). You'd free up ~$925/mo but give up $702k in retirement wealth compared to keeping current contributions.
| Scenario | Strategy | Retire NW | Retire SWR/mo | Coverage | Retirement Feasible |
|---|---|---|---|---|---|
| Full save | Keep saving (current plan) | $6,031,728 ($2.5M in today's dollars) | $20,106 | 25 yrs | Secure |
| 50% save | Half contributions | $5,725,696 ($2.4M in today's dollars) | $19,086 | 25 yrs | Secure |
| Coast | Coast — stop all contributions | $5,329,899 ($2.2M in today's dollars) | $17,766 | 25 yrs | Secure |
Coasting assumes markets deliver historical returns. A prolonged downturn early on could derail the math.
