How this calculation works
Net monthly burn equals expenses minus cash revenue. Cash divided by positive net burn estimates runway; non-positive burn is shown as cash-flow positive.
Useful output
What you receive
Estimated runway, net burn, operating result, assumptions, and CSV.
Decision guardrail
What this does not decide
Runway is a planning estimate, not a solvency opinion. Timing, growth, taxes, and one-off payments can materially change it.
