When can I stop?
Financial Independence, Retire Early. Two answers, equally important: the dollar number you need, and the calendar year you reach it.

The cost of waiting
Start 5 years later and you'll have $120.0k less in compound — and FIRE moves to year 29.5.
The first $50.0k took years. The last $50.0k toward FIRE takes months — because compound is doing the work, not you.

COAST FIRE
$159.3k
If you stop contributing today and just let the portfolio grow at 8%, you'll still reach $1.05M by year 24.5 — but only if your balance today is at least $159.3k. That's the COAST FIRE threshold.
