Runway

How many months until you run out of cash at your current burn. The single most important number for an unprofitable startup — it's your countdown clock.

Net vs gross burn

Gross burn is total monthly expenses. Net burn subtracts revenue (expenses − revenue) — the cash you actually lose each month. Investors usually mean net burn.

Why revenue growth matters

If revenue grows faster than expenses, you can reach breakeven before zero cash. Even modest monthly growth can flip a short runway into a sustainable business.

How much runway to keep

A common rule is 6–12 months minimum. Below 6 months you're fundraising or cutting costs; plan your MVP and ad budgets around that buffer.
