Burn Rate

The rate at which a company spends cash each month — critical for startups tracking their runway.

Burn rate measures how quickly a company consumes its cash reserves, typically expressed as monthly net cash outflow. Gross burn rate is total monthly spending; net burn rate subtracts any revenue, showing the net cash consumption.

For startups and pre-profit companies, burn rate is arguably the most important financial metric because it directly determines runway — how many months the company can operate before running out of cash.

Burn rate management is central to startup financial strategy. Reducing burn extends runway, giving more time to achieve product-market fit, hit growth targets, or raise the next funding round. Common levers include delaying hires, renegotiating vendor contracts, and deferring capital expenditure.

Investors closely monitor the "burn multiple" — net burn divided by net new ARR — as a measure of growth efficiency. A burn multiple below 1.5x is considered efficient; above 3x is a warning sign that growth is too expensive.
