How Cash Runway Is Calculated
Cash runway is how many months your business can keep operating at its current burn rate before running out of cash. It's calculated as:
Runway = Current Cash ÷ Monthly Burn Rate
Where Monthly Burn Rate = Monthly Expenses − Monthly Revenue (only when expenses exceed revenue — if revenue covers expenses, you're not burning cash and runway is effectively infinite until that changes).
What Counts as a Healthy Runway?
| Runway | What It Usually Means |
|---|---|
| 18+ months | Comfortable — normal operating range post-fundraise |
| 9-18 months | Fine, but start fundraising conversations soon |
| 3-9 months | Urgent — active fundraising or cost-cutting needed now |
| Under 3 months | Critical — immediate action required |
Fundraising itself typically takes 3-6 months start to close, which is why most advisors recommend starting the process with at least 9-12 months of runway remaining, not waiting until the number gets scary.
