About This Calculator

Burn rate is how much cash a company consumes each month. Gross burn is total monthly expenses; net burn is expenses minus revenue. Net burn divided into cash on hand gives runway — the number of months before the business runs out of money. This is the most critical number for any pre-profitable startup.

Estimates only — not financial, tax, legal, or investment advice. Verify important results with a qualified professional before making decisions.

gross burn = monthly expenses; net burn = max(0, expenses − revenue); annual = net burn × 12
