Quick answer
Burn Multiple Calculator: what it calculates
Burn Multiple Calculator calculates burn multiple from monthly net burn, period months and starting arr. The core method is Burn multiple = total net burn / net new ARR.

Total burn divided by net new ARR.
Net new ARR$550,000.00
61.1% growth over the period.
Total burn$510,000.00
$85,000.00 monthly burn for 6 months.
When the result is unavailable
Burn multiple needs positive net new ARR. If ending ARR is flat or lower than starting ARR, the business burned cash without adding ARR in this simplified model.
Formula
Burn multiple formula
Burn multiple = total net burn / net new ARRUse the same period for burn and ARR change. This simplified metric does not explain why burn or growth changed.
How to use
Steps
- Enter monthly net burn.
- Enter the number of months in the period.
- Enter starting ARR and ending ARR for that same period.
- Review burn multiple, net new ARR, total burn, and ARR growth.

Calculator use
Best for
- Use this burn multiple calculator to compare cash burned against net new ARR over the same period.
- Checking burn multiple formula with the formula and assumptions visible.
- Comparing the result with the sample calculation and benchmark table before using it elsewhere.
- Pricing, runway, cash flow, or work assumptions before an operating decision.
Before relying on it
Check first
- Using the burn multiple without confirming that monthly net burn, period months and starting arr describe the same real-world case.
- Ignoring that use the same period for burn and ARR change. This simplified metric does not explain why burn or growth changed.
- Relying on the number without checking whether the visible assumptions match the real-world task.
- Mixing cash and accounting profit, or monthly recurring items and one-time items.
Benchmarks
How to read the result
The calculator is a decision aid, not a fixed rule. Use the output to compare scenarios and document your assumptions. Benchmark ranges are broad planning heuristics unless this page names a specific source for the range.
Under 1xEfficient
A broad heuristic: the company added more ARR than it burned during the period.
1x - 2xWatch
Often workable, but efficiency and payback should be checked against growth stage.
2x+Heavy burn
Can be concerning unless the company is intentionally investing ahead of strong future growth.

FAQ
Common questions
What is burn multiple?
Burn multiple compares how much cash a startup burns to how much net new ARR it adds over the same period.
Should burn multiple use ARR or MRR?
It is commonly expressed with ARR. If you use MRR, keep the numerator and denominator consistent and label the result clearly.
What if net new ARR is negative?
The calculator marks the result unavailable because burn multiple is not meaningful when ARR did not increase.
Can this replace accounting or legal advice?
No. Business calculators are scenario tools. Contracts, taxes, payment timing, accounting treatment, refunds, and legal requirements can change decisions.
What should I do after using a business calculator?
Save the assumptions, compare a conservative scenario, and review the result with actual books, contracts, or an advisor before making a high-stakes decision.
Why might another calculator show a different result?
Different calculators may use different rounding, assumptions, default rates, formulas, or input timing. Compare the visible formula and inputs before relying on the number.
