How to Calculate Burn Rate and Runway

Formula

Gross Burn = Monthly Expenses Net Burn = Monthly Expenses - Monthly Revenue Runway = Cash Balance / Net Burn

Burn rate is how fast a startup spends its cash reserves. Gross burn counts all spending. Net burn subtracts revenue, giving the actual cash outflow. Runway is the number of months until the cash runs out at the current net burn rate. Startups typically aim to maintain at least 12-18 months of runway to give themselves time to reach profitability or raise the next round.

Exemplo Resolvido

A startup has $500,000 in the bank, spends $80,000/month, and earns $30,000/month in revenue.

  1. Gross Burn = $80,000/month
  2. Net Burn = $80,000 - $30,000 = $50,000/month
  3. Runway = $500,000 / $50,000 = 10.0 months
