How to use Cash Runway Scenario Calculator
Net cash burn is outflow minus inflow. Positive burn depletes available cash above the reserve; zero or negative burn does not deplete it in this model.
- Enter opening cash, protected reserve, monthly cash inflow, monthly cash outflow.
- Check the model, units, and supported limits before calculating.
- Run the tool, inspect the result, then copy or download it.
