Burn rate is the rate at which a startup spends cash, typically measured monthly. Gross burn is total spending; net burn is spending minus revenue.

What is Burn Rate?

Burn rate measures how fast a startup is spending money. It's called "burn" because early-stage startups typically lose money (burning cash) before becoming profitable.

Types of Burn Rate

Gross Burn:

  • Total monthly operating expenses
  • All money going out

Net Burn:

  • Gross burn minus revenue
  • Actual cash decrease per month
