Startup Runway Calculator
Work out how many months of runway a startup has from its cash and burn rate.
How long the money lasts
Runway is how many months a business can keep operating before it runs out of cash, found by dividing its cash on hand by its monthly burn — the net amount it loses each month. This works it out, the single most watched number in an early-stage company, since it tells you how much time you have.
Enter your cash and monthly burn to see the runway.
Why runway drives every decision
Runway turns an abstract cash balance into a deadline, and that deadline shapes everything a young company does. It tells you when you must either reach profitability, raise more money, or cut costs — and since raising money itself takes months, the practical trigger comes well before zero. Watching runway also makes the effect of decisions concrete: a new hire shortens it, a new customer extends it. The uncomfortable but vital discipline is knowing your runway at all times, because a company that watches it can act early and deliberately, while one that ignores it discovers the problem when it is nearly too late to fix.
