Burn Multiple Calculator: SaaS Formula & Capital Efficiency
Calculate your SaaS Burn Multiple with the standard formula (Net Burn ÷ Net New ARR) to measure capital efficiency.
Burn Multiple measures SaaS capital efficiency: Net Burn ÷ Net New ARR. Example: $100K net burn ÷ $60K net new ARR = 1.67x. Lower is better; under 1x is excellent.
Monthly cash burn (revenue − expenses, negative means losing cash)
New ARR added this month minus churned ARR
Burn Multiple
1.67
Good, efficient burn relative to growth.
Good efficiency. You are burning $1–2 per $1 of new ARR. This is the healthy range for most SaaS companies.
How it works
The Burn Multiple measures how much cash you burn to generate each dollar of new ARR. A lower number is better. Under 1.0 means you burn less than you grow, over 3.0 is concerning for most stages.
How to use this calculator
Follow these steps to get an accurate Burn Multiple result.
- Open the Burn Multiple Calculator.
- Enter Net Burn: your monthly cash operating loss (expenses minus revenue, as a positive number).
- Enter Net New ARR: new ARR added this month minus ARR lost to churn.
- Review your Burn Multiple. Under 1x means you are growing capital-efficiently. Above 3x is concerning for most stages. Combine with Magic Number for a complete efficiency view.
Worked examples
Plug in sample numbers to see how the Burn Multiple formula works in practice.
Growth-stage month
- Net burn
- $120,000
- Net new ARR
- $80,000
Burn Multiple = $120,000 ÷ $80,000 = 1.5x
1–2x is generally considered good for growth-stage SaaS.
Inefficient growth
- Net burn
- $250,000
- Net new ARR
- $50,000
Burn Multiple = $250,000 ÷ $50,000 = 5.0x
Above 3x usually signals a need to cut burn or accelerate net new ARR.

| Context | Guidance |
|---|---|
| Excellent | Under 1x (burn less than you grow) |
| Good | 1–2x |
| Fair / watch | 2–3x |
| Concerning | Above 3x for most stages |
Common mistakes
- Using gross burn instead of net burn — Net burn = cash out − cash in (operating). Use the absolute value of the loss.
- Mixing periods (burn monthly, ARR annual) — Keep net burn and net new ARR on the same time window.
- Ignoring churn in “new ARR” — Use net new ARR (new − churned), not bookings alone.
Frequently Asked Questions
What is the Burn Multiple?
The Burn Multiple compares your net cash burn (operating expenses minus revenue) to net new ARR (new ARR minus churned ARR) in the same period. It answers: how much cash do you incinerate for each dollar of net new recurring revenue?
What is the Burn Multiple formula for SaaS?
Burn Multiple = Net Burn ÷ Net New ARR. Net burn is monthly cash operating loss (use the absolute value). Net new ARR is new ARR added minus churned ARR. Example: $100K net burn ÷ $60K net new ARR = 1.67x Burn Multiple.
How do you calculate the Burn Multiple?
Divide net burn by net new ARR for the same period. Example: $100K net burn ÷ $60K net new ARR = 1.67x. Use this free Burn Multiple calculator to run the formula instantly.
What is a good Burn Multiple for SaaS?
Under 1x is excellent (you burn less than you grow). 1–2x is good for growth-stage companies. 2–3x is fair but warrants monitoring. Above 3x is concerning. Late-stage public SaaS companies average around 1.5–2x. During hypergrowth phases, higher burn may be acceptable with a clear path to efficiency.
How do I improve my Burn Multiple?
Reduce net burn by cutting non-essential expenses and improving gross margin. Increase net new ARR by improving sales velocity, reducing churn, and driving expansion revenue. The best companies improve both sides simultaneously.
What does a negative Burn Multiple mean?
A negative net burn (cash flow positive) means you are generating more revenue than you spend. In this case, the Burn Multiple is not meaningful, you have already achieved profitability. Companies with negative burn should focus on growth rate rather than efficiency.
How does Burn Multiple compare to Rule of 40?
Burn Multiple focuses specifically on capital efficiency (burn vs. growth). Rule of 40 balances growth with overall profitability. Use Burn Multiple when fundraising or managing runway. Use Rule of 40 for overall business health assessment. Both are important for different audiences.
