The Cash Runway Calculator.

Your cash runway is the number of months your business can keep the lights on before the bank account hits zero. This free cash runway calculator does the math in seconds: enter your cash on hand, monthly revenue, and monthly expenses, and it tells you exactly how long your money lasts. Learn about your monthly burn rate, your net cash flow, and the month you’d run out.
 
Think of it as your business’s fuel gauge. You wouldn’t drive across the desert without checking how much gas is in the tank. Running a business without knowing your runway is the same bet except just with rent, payroll, and your paycheck riding on it.
 
It works for any local service business like lawn care, cleaning, contracting, salons, food, you name it.
