Frequently Asked Questions
This tool takes your current cash and monthly burn as direct inputs to compute runway. Burn Rate Calculator Tool instead takes monthly expenses and revenue, derives your net burn from those, and then computes the same runway figure — use whichever inputs you already have on hand.
Runway (months) = Total Cash ÷ Monthly Burn, rounded down to whole months. It also shows the equivalent in years.
No — it assumes your monthly burn stays constant. If your burn is expected to rise (e.g. from hiring) or fall (e.g. from cost cuts), the actual runway will differ from this estimate.
Your net cash outflow per month — total expenses minus any revenue. If you're not sure, use the Burn Rate Calculator Tool first to derive it from your expenses and revenue.
