How the Cash Runway Forecast Calculator works
A plan that dips below zero in month three and recovers afterwards still fails. The lowest balance is what matters, not the ending one, and timing a planned investment differently is often cheaper than raising more money to survive it.

Frequently asked questions
How do I forecast cash runway?
Month by month, with revenue and costs growing at their own rates and any one-off investments placed in the month they occur. Averages hide exactly the dip that kills you.
Why does the lowest balance matter most?
Because you cannot survive a month with negative cash by pointing at a positive twelve-month total. The trough is the binding constraint.
Should I model a downside case?
Always. A plan that only works at the forecast growth rate is not a plan. Model flat revenue and see whether the business survives it.
How do I extend runway without raising?
Delay discretionary investment, negotiate supplier terms, collect faster, and cut the costs that do not produce revenue. All four are available before a raise and all four are usually cheaper.
