Here's the counter-intuitive part: Rosa can stop making the $100,000 in annual retirement contributions entirely, and the engine still projects a $36M net worth at 65. That's because $660,000 compounding untouched for 30 years does the heavy lifting, while the $220,000 in liquid taxable savings stays available for anything life throws at her before retirement. The projected spend of $13,719 a month in retirement dollars is covered with 25 years of runway.
With $660,000 in retirement accounts and zero new contributions, the engine projects $36M 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 $4.1M in retirement wealth compared to keeping current contributions.
| Scenario | Strategy | Retire NW | Retire SWR/mo | Coverage | Retirement Feasible |
|---|---|---|---|---|---|
| Full save | Keep saving (current plan) | $39,618,588 ($16M in today's dollars) | $132,062 | 25 yrs | Secure |
| 50% save | Half contributions | $39,618,588 ($16M in today's dollars) | $132,062 | 25 yrs | Secure |
| Coast | Coast, stop all contributions | $35,534,657 ($15M in today's dollars) | $118,449 | 25 yrs | Secure |
Coasting assumes markets deliver historical returns. A prolonged downturn early on could derail the math.
Rosa's an illustrative example, but if you're in your 30s with serious savings already stacked, your own Coast number might be closer than you think. Run your actual plan and find out.
