### The one number every founder should check monthly

Runway is the difference between a pivot and a panic. This calculator takes your cash on hand, monthly revenue, monthly expenses, and growth rates — then simulates your bank balance month by month so you know exactly when the money runs out, and what moves the date.

### Key features

– **Runway headline** — months remaining plus the exact calendar month your cash hits zero.
– **36-month cash chart** — green/red monthly bars show burn shrinking (or growing) as revenue compounds.
– **Dual growth modeling** — revenue growth and expense growth modeled independently, because hiring and sales rarely move together.
– **Break-even detection** — automatically flags the month the business turns cash-positive, if it does inside the window.
– **One-time injections** — model a fundraise, loan, or founder top-up landing in month one.
– **5-lever comparison table** — see exactly how many months a 10% cost cut, 25% cost cut, faster growth, a $100k raise, or frozen expense growth each buy you.
– **Under-6-months alert** — a prominent warning appears when runway gets dangerous.
– **Private by design** — your financial numbers never leave your browser.

### How it works
