Your Runway
7months
Healthy
6+ months gives you room to operate. Use it to hit the milestones that make your next raise (or profitability) easier — don't get comfortable and let it slip to 3 months.
Know your runway before it knows you
The fastest way to kill a startup is to run out of cash without seeing it coming. This calculator turns three numbers — cash in the bank, monthly expenses and monthly revenue — into the one number that should sit on your wall: how many months you have left. Check it every month, and let it drive your decisions on hiring, spending and when to raise.
Common questions
What is startup runway?
Runway is how many months your startup can keep operating before the cash runs out, at your current burn rate. It's the single most important number for an early-stage founder — it tells you how much time you have to hit your next milestone or raise.
How is it calculated?
Runway = available cash ÷ net monthly burn, where net burn is your monthly expenses minus any monthly revenue. If revenue covers expenses, your runway is effectively unlimited — you're at break-even.
When should I start raising?
Start while you still have 6+ months, because fundraising almost always takes longer than you expect. Trying to raise with 2 months left puts you in a weak position — investors can smell desperation.
