Runway Formula and Inputs
Runway = cash balance ÷ monthly burn rate.
Business metrics are most useful when the inputs come from the same time period and the same definition. Before comparing results, decide whether you are measuring revenue, profit, customers, orders, units, leads, or another specific business event.
| Input | How to Use It |
|---|---|
| Cash balance | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
| Monthly burn | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
| Revenue trend | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
| Planned expenses | Use a value from the same campaign, product, period, or business scenario as the other inputs. |
Worked Runway Example
If a business has $240,000 in cash and burns $40,000 per month, runway is about 6 months.
After calculating one result, change one input at a time. This makes it easier to see whether price, cost, volume, conversion rate, retention, ad spend, or labor is driving the business outcome.
How to Interpret the Result
Runway is a warning metric. A longer runway gives more time to improve revenue, raise capital, reduce costs, or adjust strategy.
A business calculator can point you toward better decisions, but the number should be reviewed with context: margin, cash timing, customer quality, seasonality, capacity, and whether the result can repeat.
Common Runway Mistakes
- Assuming burn stays constant.
- Ignoring upcoming hires or renewals.
- Waiting too long to raise or cut costs.
- Not separating committed from optional expenses.
