Burn Rate Calculator

Calculate monthly net cash burn from an opening balance, a closing balance, and the months between.

Monthly burn

How it works

The change in cash between the two dates is divided by the months in between, giving net burn rather than gross spending.

Example

Falling from $640,000 to $415,000 over nine months is $225,000 of cash used and $25,000.00 a month.

This tool is for estimation and education, not financial, tax, or legal advice.

No. The calculation runs locally in your browser.

Which figures should I use?

Whatever period you are judging — a month, a quarter, a year — as long as every input covers the same one.
