Runway & burn
Runway is the one number that decides how much time you have to be right. Enter your cash, monthly spend, and revenue to see your net burn, months of runway, the date you hit zero, and when to start raising so you are not negotiating from desperation.
- Net burn / month
- $0
- Runway
- 0 mo
- Out of cash

Estimate only; assumes flat spend and revenue. Reality compounds both ways.
Raise before you need to
The cruel rule of fundraising is that the best time to raise is when you do not yet need the money, because runway is leverage. A round takes months to close, so the practical deadline is not when cash hits zero but several months earlier. Aim to start the raise with six months still in the tank; the calculator flags that line for you.
