How to read this metric

What it measures

Burn Rate is the rate at which a company spends its capital to finance overhead before generating positive cash flow from operations. It is usually measured on a monthly basis.

Why it matters

For startups, burn rate is the ticking clock. It tells you how much time you have before you either need to reach profitability or raise more capital. High burn rates without corresponding high growth are a major red flag for investors.

How to manage burn rate

  1. Reduce Fixed Costs: Review rent, subscriptions, and other recurring expenses that can be trimmed.
  2. Optimize Headcount: Ensure every hire is essential and directly contributing to growth or product value.
  3. Increase Revenue: Focus on sales and customer retention to move toward “default alive” (profitability).
  4. Deferred Spending: Postpone non-essential equipment purchases or marketing experiments until cash flow improves.
