Coast FIRE Calculator · Launching Jun 8

Your Coast FIRE number.
And the plan to get there.

Coast, Barista, Lean, Fat. Every FIRE type, one calculator. And a $19 PDF report you can save and send to your spouse, or hand to your CPA.

I'm shipping this on June 8, 2026. Leave your email and you'll get day-one access at $19 lifetime instead of the $29 launch price. I won't send you anything else unless you want me to.

Stress-test the plan.

Returns drop to 5%. You bump savings to 30%. You retire at 50, not 55. The PDF runs every scenario you care about and lays them on the same chart.
