Startup Runway Calculator
Estimate how many months a startup can operate before its available cash is depleted.
How to Use the Startup Runway Calculator
Enter the cash currently available and the startup’s monthly net burn rate. The calculator divides cash by monthly burn to estimate how many months the business can continue before cash is exhausted if conditions remain unchanged.
Practical Example
A startup with USD 900,000 in cash and a USD 75,000 monthly net burn has about 12 months of runway.
Factors That Affect the Result
Revenue growth, hiring, marketing spend, financing, one-time expenses and changes in operating costs can quickly change runway. Update the inputs regularly.
Frequently Asked Questions
What is startup runway?
Runway is the estimated number of months a company can operate before its available cash is depleted.
Should I use gross or net burn?
Net burn is usually more useful for runway because it accounts for cash revenue as well as cash expenses.
Can runway increase without new funding?
Yes. Higher revenue or lower expenses can reduce net burn and extend runway.
Runway and Burn Rate
Cash runway estimates how long available cash can support the current net burn rate. If revenue, expenses or financing change, runway changes as well. Scenario analysis is more useful than treating a single runway number as a fixed forecast.
