With $378,000 in retirement accounts and zero new contributions, the engine projects $5.0M net worth at age 65 on $5,960/mo of retirement spending (≈ $3,300/mo in today’s dollars). You'd free up ~$1,375/mo but give up $469k in retirement wealth compared to keeping current contributions.

| Full save | Keep saving (current plan) | $5,489,768 ($3.0M in today's dollars) | $18,299 | 25 yrs | Secure |
| 50% save | Half contributions | $5,388,266 ($3.0M in today's dollars) | $17,961 | 25 yrs | Secure |
| Coast | Coast, stop all contributions | $5,020,718 ($2.8M in today's dollars) | $16,736 | 25 yrs | Secure |
