About the Startup Runway Calculator
Runway is the number of months a startup can keep operating before it runs out of cash, assuming spending and revenue stay at their current pace. It's one of the most closely watched numbers by founders and investors alike.
Formula: Net Burn = Monthly Expenses − Monthly Revenue · Runway (months) = Cash on Hand ÷ Net Burn
If monthly revenue already exceeds monthly expenses, net burn is zero or negative and runway is effectively infinite — this calculator applies to companies still spending more cash than they bring in. Most investors expect startups to raise their next round with at least six months of runway to spare.
