Burn multiple measures how much net cash your startup spends to generate new ARR. Use it to assess growth efficiency, but pair the ratio with a clear explanation of the period measured and the factors behind the result.
How do you calculate burn multiple?
Burn multiple compares net cash burned with net new annual recurring revenue (ARR) added over the same period. The calculation is:
Burn multiple = net cash burned ÷ net new ARR
For example, if your company burns $3M and adds $1M in ARR during the same period, the result is 3x. In practical terms, that is three dollars of net cash burned for each dollar of new ARR.
The timeframe matters as much as the arithmetic. Use the same start and end points for both figures. If the cash burn covers one period but the new ARR covers another, the resulting ratio may be misleading. Make sure you use net new ARR, not your company’s total ARR: the metric is intended to compare spending with revenue added during the period.
Before sharing the calculation, check that the inputs are consistent and that you can describe what they include. A ratio without a defined period or understandable inputs can be difficult to assess. Clear measurement makes the number more useful for your own planning and for investor conversations.
What does burn multiple tell investors?
The metric brings two aspects of performance, cash use and ARR growth, into a single ratio. Investors may use it as an early screen for growth efficiency. A high result can lead to questions about the cost of acquiring or sustaining growth, but it does not explain the business on its own.
In 2026, a burn multiple under 2 is considered fundable, while a result under 1.5 is considered strong. Treat these as guideposts rather than automatic judgments. Falling below a benchmark does not guarantee that a company is healthy or will raise capital. A higher figure, meanwhile, does not reveal why spending is high or whether that spending is intentional.
Investors may also want to understand how the metric is changing. If it is improving, explain what is contributing to the improvement. If it is moving in the wrong direction, clarify whether the result reflects planned investment, slower ARR growth, or spending that has not adjusted. The context helps explain what a single ratio cannot.
How can you improve burn multiple without cutting blindly?
The aim is to increase revenue faster than spending. Reducing costs may contribute, but it is not the only route. Retention, stronger-margin channels, and pricing power can also affect the relationship between cash burn and new ARR.
Consider the business’s specific drivers:
- Strengthen retention: Customers who stay and continue paying can support recurring revenue without relying only on new customer acquisition.
- Prioritize higher-margin channels: Growth through channels with stronger margins can improve the relationship between spending and the ARR added.
- Review pricing: Where customers see clear value, pricing can influence revenue growth without spending needing to increase at the same pace.
- Connect costs with outcomes: Assess whether the costs supporting growth are contributing to durable new ARR instead of assuming every expense has the same effect.
A blanket reduction in expenses may lower cash burn, but it can also interfere with growth. Consider which costs support revenue and whether the resulting ARR is durable. The most useful changes will depend on your business, so explain the reasoning behind the actions you choose.
What burn multiple mistakes should you avoid?
A few common errors can make the figure less informative or make it harder to explain.
- Using different time periods: The cash burn and net new ARR must cover the same window. Otherwise, the ratio does not compare spending and growth across a consistent period.
- Substituting total ARR for net new ARR: Existing ARR describes the revenue base. The burn multiple calculation uses the ARR added during the period.
- Treating a benchmark as a verdict: The 2026 guideposts, under 2 for fundable and under 1.5 for strong, do not replace an explanation of your business’s results.
- Focusing exclusively on cost cutting: Retention, higher-margin channels, and pricing power may help improve the ratio too.
- Presenting the number without its drivers: Be ready to explain both the cash burned and the net new ARR, as well as what you are doing to improve the relationship.
How should you explain burn multiple during a fundraise?
Make the calculation easy to follow: state the period, show the inputs, and give the resulting multiple. Then explain what changed during that period and what is influencing the trend. This gives investors more than a standalone figure to evaluate.
If your ratio is high, describe the investment behind it and the operational changes you are considering. If it is improving, connect that shift to factors such as revenue growth, retention, margins, or pricing. Avoid leaving investors to infer the reason from the ratio alone.

Frequently Asked Questions
What is the formula for burn multiple?
Divide net cash burned by net new ARR over the same period. If a company burns $3M and adds $1M in ARR in that period, its burn multiple is 3x.
What is a good burn multiple in 2026?
Under 2 is considered fundable, and under 1.5 is considered strong. These are guideposts, not guarantees or complete measures of a company’s health.
Why do investors look at burn multiple?
It gives investors an early view of how efficiently a startup turns net cash burn into new ARR. A higher ratio may prompt questions about the cost of growth, but it does not explain the reasons behind the number.
What can improve a startup’s burn multiple?
Growing revenue faster than spending can improve the ratio. Better retention, higher-margin channels, and pricing power are potential levers, alongside reviewing whether spending supports durable new ARR.
Does a lower burn multiple prove a company is healthier?
No. The ratio covers cash burned and new ARR, not every aspect of the business. Explain the timeframe, the factors driving the result, and whether the growth is durable.
