How to Use the Cash Flow Runway Calculator
Estimate runway months, break-even timeline, and projected monthly cash balances from your current burn profile.
Before You Start
- Use your latest cash reserve and monthly revenue/cost data.
- Estimate growth conservatively unless you have signed pipeline coverage.
Step-by-Step
- Enter reserve and cost profile: Add current cash, monthly revenue, gross margin, fixed costs, and debt service.
- Set growth and safety assumptions: Input expected monthly growth and desired safety buffer.
- Run projection: Review runway estimate and monthly net cash flow trend.
- Use the projection table: Watch when cash approaches buffer and where intervention is needed.
How to Read the Output
- Runway is scenario-based and assumes your entered growth/cost pattern continues.
- A positive monthly net trend does not remove short-term cash risk if reserve is already low.
Common Mistakes to Avoid
- Ignoring debt obligations or annualized costs that hit monthly cash reality.
- Using optimistic growth assumptions without lead and conversion support.
