About the Burn Rate Calculator

Burn rate measures how quickly a company spends its cash reserves each month. Runway is how many months of operation remain at the current burn rate before cash runs out.

Formula: Monthly Burn Rate = (Starting Cash − Current Cash) ÷ Months Elapsed · Runway = Current Cash ÷ Monthly Burn Rate

Startups and growing businesses track burn rate closely to plan fundraising timelines and avoid running out of cash before reaching profitability or the next funding round.
