Burn Rate

Quick Summary

Burn rate is like measuring how fast you're spending your savings - it tells you exactly how many months you have left before you run out of money.

In-depth Explanation

Burn rate is a critical metric for startups and growing companies that measures how quickly they're consuming their available capital. It's essentially the speed at which a company is spending money relative to its revenue.

Types of Burn Rate

Gross Burn Rate

  • Total spending: All company expenses combined
  • Includes everything: Salaries, rent, marketing, operations
  • Shows total consumption: How much cash is leaving the bank

Net Burn Rate

  • Revenue-adjusted: Gross burn minus monthly revenue
  • True consumption rate: Net amount of capital being depleted
  • More accurate picture: Accounts for incoming revenue

Calculating Burn Rate

Monthly Formula

Monthly Burn Rate = (Starting Cash - Ending Cash) / Number of Months

From Expenses

Monthly Burn Rate = Total Monthly Expenses - Monthly Revenue

Runway Calculation

Runway (months) = Current Cash / Monthly Burn Rate
