Burn Multiple Calculator

Use this burn multiple calculator to compare same period monthly net burn, total burn, net new ARR, ARR growth, burn multiple, and cash efficiency before reviewing runway or SaaS growth assumptions.

Planning estimate

Live calculator

Burn multiple

Burn multiple0.93x

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.

Planning comparison only. Check estimates, omitted costs, timing, and constraints before making an operating decision.

What it calculates

Burn Multiple Calculator uses monthly net burn, period months, starting ARR, and ending ARR to estimate total burn, net new ARR, ARR growth, burn multiple, and cash efficiency over the same period.

Formula

Burn multiple formula

Burn multiple = total net burn / net new ARR

Use the same period for burn and ARR change. This simplified metric does not explain why burn or growth changed.

How to use

Steps

  1. Enter monthly net burn.
  2. Enter the number of months in the period.
  3. Enter starting ARR and ending ARR for that same period.
  4. Review burn multiple, net new ARR, total burn, and ARR growth.

Calculator use

Best for

  • Estimating business pricing, margin, retention, runway, dilution, revenue, or profitability before an operating decision.
  • Comparing base, conservative, and optimistic assumptions with the revenue, cost, churn, or payment timing visible.

Before relying on it

Check first

  • Mixing cash flow, accounting profit, bookings, revenue recognition, one-time fees, and recurring revenue.
  • Leaving out taxes, refunds, discounts, churn, payment delays, support cost, contractor cost, or owner time.
  • Using one optimistic case as the operating plan without checking downside assumptions.

Details

What to know before using the result

Same period inputsMatch burn and ARR movement

Monthly net burn multiplied by period months should cover the same period used for starting ARR and ending ARR so burn multiple compares one cash period to one ARR movement.

Positive net new ARRRequired for a meaningful ratio

Burn multiple is not meaningful when ending ARR is flat or lower than starting ARR because the business spent cash without adding net new ARR in this simplified model.

Efficiency vs runwayDifferent cash questions

Burn multiple shows cash efficiency per ARR added. Runway shows how many months cash lasts, so it should be checked separately before changing hiring or spend.

Next decisionConnect cash burn to SaaS health

After checking burn multiple, review MRR, churn rate, LTV/CAC, startup runway, and small-business cash flow before changing hiring, acquisition, or retention plans.

Benchmarks

How to read the result

Under 1x: Efficient.

A broad heuristic: the company added more ARR than it burned during the period.

1x - 2x: Watch.

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.

Is a lower burn multiple always better?

Lower burn multiple usually signals better cash efficiency, but it should be read with ARR growth rate, stage, runway, gross margin, and the quality of revenue added.
