Do you know exactly who owns this pain day to day?
Runway is the single most important number for a pre-profitability startup, and the one most founders check too infrequently. It should be a monthly ritual, not a once-a-quarter surprise.
This calculator gives you months of runway and the specific calendar month you'd hit zero cash — so you know exactly when you need to have raised, cut costs, or reached profitability.

Why the exact zero-cash date matters
'6 months of runway' feels abstract. 'You run out of cash in June 2027' is a deadline. Founders who track the actual calendar date make sharper decisions about when to start fundraising (typically 6+ months before zero cash) and when to cut burn.
The runway trap
Runway calculated from a single month's burn rate is fragile — burn tends to increase as you hire, and revenue growth is rarely linear. Recalculate monthly, not once at the start, and build in a buffer for burn creeping upward.
How this calculator works
- Enter your current cash on hand.
- Enter your monthly costs (payroll, tools, rent, ads).
- Enter your current monthly revenue.
- The calculator shows net burn, months of runway, and the calendar month you'd hit zero cash.

Frequently asked questions
How often should I recalculate my runway?
Monthly, minimum. Burn rate changes as you hire or cut costs, and revenue rarely grows in a straight line — a runway number from three months ago can be dangerously stale.
When should I start fundraising relative to my runway?
Most experienced founders start the fundraising process with 6–9 months of runway remaining, since raises commonly take 3–6 months from first conversation to funds in the bank.
What if my monthly revenue exceeds my costs?
You're profitable — there's no runway limit in the traditional sense, since you're not burning down cash. The calculator will show this explicitly rather than a misleading runway figure.
