How to use the Cash Flow Forecast Calculator

Enter your opening cash balance.
Enter monthly cash in and cash out, with growth rates.

What does this tool do?

Profitable businesses can still run out of cash. A cash flow forecast tracks money actually coming in and going out each month, so you can see a shortfall coming months ahead.

Burn rate is how much cash you lose per month; runway is how many months your current cash would last at that rate.

Why use it?

Month-by-month table.
Runway and lowest balance.
Growth on both sides.
