Formula used

Monthly Burn Rate = (Starting Cash − Ending Cash) ÷ Number of Months

Example calculation

Starting Cash = $100,000, Ending Cash = $76,000, and Period = 3 months. Monthly Burn Rate = (100,000 − 76,000) ÷ 3 = $8,000.00.

What the result means

A higher burn rate means cash is being used faster. This is especially useful for startups and project teams that need to monitor runway and funding needs.
