Burn Rate Calculator









Burn rate is a financial metric that shows how quickly a company is spending its available cash. It is particularly important for startups and businesses that are not yet profitable. Burn rate helps founders and investors understand how long a company can operate before needing additional funding.


💡 Burn Rate Formula

The standard formula to calculate burn rate is:

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

This gives you the average monthly cash outflow, indicating how fast your business is “burning” its cash reserves.


🧮 How to Use the Burn Rate Calculator

  1. Starting Cash ($): Enter your beginning balance for the period.
  2. Ending Cash ($): Enter your ending balance after the period.
  3. Time Period (in Months): Input the duration between the starting and ending cash amounts.

Click Calculate to see your monthly burn rate.


📊 Example

If your company starts with $200,000, ends with $140,000 after 3 months:

nginxCopyEditBurn Rate = ($200,000 - $140,000) / 3 = $20,000 per month

This means your business is spending $20,000 per month.


🚀 Why Burn Rate Matters

  • Operational Planning: Adjust hiring, marketing, and R&D based on your cash runway.

  • Survival Metric: Helps predict when the business will run out of cash (runway).

🧠 FAQs

1. What is a good burn rate?
Depends on your business stage. In early phases, a high burn rate is common, but it should correlate with growth or milestones.

2. What is negative burn rate?
This means you're generating more cash than you're spending — a positive sign.

3. What’s the difference between burn rate and cash runway?
Burn rate = how much you're spending monthly.
Cash runway = how many months your cash will last at the current burn rate.

4. Is burn rate pre- or post-revenue?
Burn rate typically refers to net cash outflow regardless of revenue.

5. Can a profitable company have a burn rate?
Yes, especially if investing in future growth causes expenses to exceed revenue temporarily.
