Try your own numbers

A quick demo: six numbers, no sign-up. The engine projects them year by year to 95, with taxes, your 401(k), the withdrawal order in retirement and Social Security, the same way it projects the example households. A free account is where you go deeper and keep it: a partner, a house, kids, one-off costs, and futures side by side.

This is a quick demo, not your plan. Six numbers and a few fixed assumptions, and nothing is kept. To model your real situation (a partner, a house, kids, big one-off costs, several futures side by side) and save it, create a free account.

A plain household, so you can see the shape: single filer; savings split 60% 401(k), 30% brokerage, 10% cash; your 401(k) gets what you can afford up to the limit, the rest of what you don't spend is invested; your state taxes at 5%; spending stays level in today's dollars. Nothing here is saved to an account.
