Runway tracker

How long your savings last, and how much that changes once income starts arriving. Knowing this number is the difference between a considered decision and a panicked one.

Growth compounds on the previous month. Fifteen percent is optimistic but not fantasy for something early and small; zero is a perfectly honest answer if nothing is growing yet.

Why this matters more than any income number

Runway is what decides whether you get to keep going. People with six months make calm decisions. People with three weeks take bad clients, discount too hard, and quit right before it works.

If the number is small, the fix usually isn't earning more — it's cutting spending or keeping a job longer while you build. Neither is a failure. Both buy time, and time is the actual input.

A note on the growth assumption

Compounding growth flatters plans. Fifteen percent a month is fine for a few months from a small base and unrealistic to sustain for a year. Set growth to zero to see the honest floor, then treat anything above it as upside.
