How this calculator works
Runway starts with cash balance and subtracts monthly net burn. When growth rates are entered, revenue and expenses compound monthly.
Formula
runway_months = cash_balance / (monthly_expenses - monthly_revenue)Example calculation
With 120,000 cash, 20,000 expenses, and 5,000 revenue, simple runway is about 8 months.
Important considerations
Runway is a planning model. It does not include fundraising probability, one-off costs, delayed receivables, or seasonality.
FAQs
What if revenue is higher than expenses?
The calculator reports the business as sustainable or cash-positive instead of forcing a runway date.
