Runway calculator
See how many months your current cash lasts. Values stay in your browser and are never stored.
What is calculated
- Monthly cash out = labor cost + other spending
- Monthly net burn = monthly cash out − monthly cash in
- Runway = cash on hand ÷ monthly net burn
How the bands are set
- 12 months or more — long-range view
- 6 to 12 months — time to review the plan
- 3 to 6 months — review this first
- Under 3 months — review immediately
Common questions
- Are the amounts I enter stored anywhere?
- No. Everything is calculated in your browser and nothing is sent to a server. Reloading the page clears it.
- How much should I trust this number?
- It is a rough estimate. It divides cash by a steady monthly burn, so seasonality and one-off spending are not reflected.
- How is BetaFIN different from this?
- This calculator looks at one moment. BetaFIN organises cash and profit on the same basis every month and connects why they moved to what to check next.
