How long will your cash last?
Model uncertainty with Monte Carlo simulation and scenario planning.
Spreadsheet forecasts assume your burn rate stays constant. It won't. Model the uncertainty instead of ignoring it.
You'll get a runway range with confidence intervals, scenario comparisons, a funding gap estimate, and a decision deadline.
What You'll See
Most runway calculations divide cash by burn. That's a guess dressed as maths.
Runway range
Three scenarios, not one: pessimistic, likely, and best-case months of runway. Based on 1,000 Monte Carlo simulations of your cashflow.
Cash-out probability
Chance of running dry in 6 months. Likelihood of reaching 9+ or 12+ months. Know the odds, not just a projection.
Milestone probability
Will you hit your revenue target before cash runs out? Set the number and see the odds.
Scenario modelling
Adjust growth rate, cost inflation, cash injection. See how each decision shifts your runway outlook.
Funding gap
How much do you need to raise? The gap between where you are and where you need to be. With 80% confidence, not best-case optimism.
Decision deadline
When do you need to start raising? The date you lose negotiating leverage, not the date the cash runs out.
How It Works
Enter Financials
Current cash, monthly burn, and revenue (if any).
Set Variance
Define how much your numbers might vary month-to-month.
Run Simulation
1,000 Monte Carlo scenarios, calculated in seconds.
