The burn rate is how much more your business spends each month (net losses); the runway is how many months your current cash lasts before running out. Not financial advice.

This startup runway calculator works out how many months your business can survive from your available cash and monthly burn rate.

Know your deadline before it’s urgent

Runway is the clock every founder should watch: it tells you exactly how much time you have before you need to be cash-flow positive or raise more funding. Recalculating it as your burn rate changes helps you plan hiring, spending and fundraising with a clear deadline in mind. Not financial advice.
