What is Cash Runway?
Cash runway is how long your business can operate before it runs out of money, given current cash and net burn. It's the single most important number for any pre-profitability startup.
Runway (months) = cash on hand ÷ net monthly burn
How to read your result
- If net burn is zero or negative, you're sustainable — runway is effectively unlimited.
- Most investors want to see 18–24 months of runway after a raise.
- Cutting burn extends runway faster than almost anything else.
- Recalculate whenever spend or revenue changes materially.
