Their $132,000 in retirement savings, left completely alone from age 35 to 65, is projected to reach $5.7M, enough to cover $6,554 a month in retirement spending (roughly $2,700 in today's dollars) for 25 years. The number that makes this work isn't their income or their discipline: it's time. Stopping $11,100 in annual contributions sounds like a sacrifice, but the engine shows their existing balance doesn't need the help.
With $132,000 in retirement accounts and zero new contributions, the engine projects $5.7M 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 $562k in retirement wealth compared to keeping current contributions.
| Scenario | Strategy | Retire NW | Retire SWR/mo | Coverage | Retirement Feasible |
|---|---|---|---|---|---|
| Full save | Keep saving (current plan) | $6,245,634 ($2.6M in today's dollars) | $20,819 | 25 yrs | Secure |
| 50% save | Half contributions | $6,009,363 ($2.5M in today's dollars) | $20,031 | 25 yrs | Secure |
| Coast | Coast, stop all contributions | $5,683,531 ($2.3M in today's dollars) | $18,945 | 25 yrs | Secure |
Coasting assumes markets deliver historical returns. A prolonged downturn early on could derail the math.
