How it works & examples

What is cash burn rate?

Cash burn rate measures the average monthly decline in a cash balance. It is useful for understanding recent spending pace and estimating cash runway.

How to use this tool

Monthly burn = (starting cash − ending cash) ÷ months. Use balances from the beginning and end of the same period and a positive number of months.

Example

A cash balance falling from $150,000 to $90,000 over three months gives average monthly burn of $20,000.

Understanding your result

A negative result means the cash balance grew. Fundraising, loans, asset sales, and one-time purchases affect balances, so this simple measure may differ from recurring operating burn.
