Calculate normalized ARR
Monthly plans count at their monthly price. Annual plans are divided by 12 first. One-time fees stay visible but never enter MRR or ARR.
Excluded one-time fees: $5,000. This calculator does not forecast churn, expansion, failed payments, taxes, or cash timing.

An ARR calculator estimates normalized annual recurring value by converting every active recurring plan to a monthly equivalent, summing MRR, and multiplying by 12. It excludes setup fees, non-recurring work, taxes, and unsigned pipeline, so the result is a planning metric—not recognized revenue, profit, or proof of business quality.

The calculator returns normalized ARR, not revenue or profit
The calculator returns normalized ARR, not recognized revenue or profit: it converts each active recurring plan into monthly recurring revenue (MRR), sums those monthly values, and multiplies the total by 12.
Stripe’s recurring-revenue guidance describes this MRR-to-ARR relationship: a monthly subscription contributes its monthly price, while an annual subscription contributes its annual contract value divided by 12.
This output makes different contract schedules comparable. It does not show revenue recognized under accounting rules, whether customers will renew, or whether the business is profitable. The SEC’s financial-statement guidance distinguishes income-statement reporting from operating metrics such as ARR.
For the monthly starting point, see what MRR means. For the annualized view, see what ARR means.
Enter each plan as an active monthly or annual recurring commitment
Enter active customer counts and recurring prices separately for monthly and annual plans, then normalize the annual values into monthly equivalents.
Use these steps:
- 1.Enter active monthly customers and their monthly recurring price.
- 2.Enter active annual customers and their annual contract value.
- 3.Divide annual contract value by 12 to obtain monthly equivalent value.
- 4.Add monthly-plan value and annual-plan value to calculate total MRR.
- 5.Multiply total MRR by 12 to calculate ARR.
- 6.Leave setup charges, taxes, non-recurring services, and unsigned opportunities outside the calculation.
The key input is recurring commitment, not simply cash collected. An annual customer may pay upfront, but the calculator treats that contract as a monthly equivalent so monthly and annual plans share one comparison base. Annual contract value must not be added as though the full amount represented one month of MRR.
Make the assumptions visible. A plan that is paused, canceled, unsigned, or not genuinely recurring should not be treated as active recurring value. This treatment is consistent with Stripe’s recurring-revenue guidance.
The mixed-plan example produces $82,800 in ARR
The mixed-plan example produces $6,900 in MRR and $82,800 in ARR.
| Plan | Calculation | Monthly equivalent | Annualized value |
|---|---|---|---|
| Monthly plans | 100 × $49 | $4,900 MRR | $58,800 ARR |
| Annual plans | 20 × $1,200 ÷ 12 | $2,000 MRR | $24,000 ARR |
| Combined recurring plans | $4,900 + $2,000 | $6,900 MRR | $82,800 ARR |
The monthly group contributes $4,900 in MRR; multiplying by 12 gives $58,800 in ARR. The annual group contributes $24,000 in contracted recurring value for the year. Dividing by 12 gives $2,000 in MRR, and annualizing that monthly equivalent returns $24,000 in ARR.
Together, the plans produce $6,900 MRR and $82,800 ARR. A $5,000 setup fee remains outside both figures because it is one-time.
This method prevents double counting: annual contracts enter once through their monthly equivalent, and the combined MRR is annualized once through the final MRR × 12 calculation. The same recurring dollars are not counted separately as annual cash and monthly revenue.
Include recurring value and exclude one-time or unsigned items
Include active recurring plans and exclude items that do not represent an ongoing recurring commitment.
| Item | Include in ARR? | Treatment |
|---|---|---|
| Active monthly subscription | Yes | Count monthly price |
| Active annual subscription | Yes | Divide annual value by 12 |
| One-time setup fee | No | Keep outside ARR |
| Non-recurring services | No | Keep outside ARR |
| Taxes | No | Exclude from recurring value |
| Unsigned pipeline | No | Exclude until it becomes active recurring business |
A recurring service charge belongs in the calculator when it is part of an active plan. A one-time implementation project does not become recurring merely because it appears on the same invoice as a subscription.
Taxes may be collected from customers, but they do not represent normalized recurring plan value. Unsigned pipeline also stays outside the result because it is not active contracted business; including it would turn a current operating metric into a forecast.
ARR supports planning and comparison, but it should not be described as recognized revenue or profit. Use it alongside broader analysis, including unit economics, rather than treating it as a complete business assessment.
A good ARR has no universal threshold
There is no universal answer to “what is a good ARR?” because ARR is meaningful only in context. The same figure can come from different customer counts, pricing structures, contract terms, renewal patterns, cost profiles, and business models.
For internal planning, accuracy and consistency matter: apply the same inclusion and exclusion rules each time. For comparison, match definitions and measurement periods before evaluating the numbers.
ARR does not prove profit or success. A company may have recurring contracts and still face high operating costs, weak retention, or other financial pressures. A smaller ARR may be appropriate for an early or narrowly focused business.
The calculator answers, “How much active recurring value does this plan base normalize to annually?” It does not answer whether a company is successful or whether the ARR should be considered good; those questions require more evidence.
Compare public ARR claims only after aligning definitions
Public ARR claims are useful only after definitions, timing, scale, and evidence are aligned.
Use this comparison sequence:
- 1.Confirm that the figure is based on active recurring plans.
- 2.Check that annual contracts were normalized rather than double counted.
- 3.Separate setup fees and non-recurring services.
- 4.Exclude unsigned pipeline.
- 5.Align the measurement period and business scale.
- 6.Review supporting evidence rather than relying only on the headline number.
ProvenStartups describes its evidence approach on How It Works. That context helps assess public claims because a numerical result should be interpreted alongside the quality and scope of its evidence.
A concise calculator result message can say:
> Your normalized ARR is ready. Compare evidence-graded, same-scale examples in Projects.
Continue with projects to compare the result against examples at a similar scale and with clearly defined evidence. The goal is consistency, not a universal pass-or-fail threshold.
The verdict is to use ARR as a normalized planning metric
Use the ARR calculator as a normalized planning metric for active monthly and annual recurring plans. The formula is:
ARR = total normalized MRR × 12
For the worked example, 100 monthly customers at $49 produce $4,900 MRR, while 20 annual customers at $1,200 produce $2,000 normalized MRR. The combined result is $6,900 MRR and $82,800 ARR, with the $5,000 setup fee excluded.
The output is strongest when its boundaries remain clear. It measures normalized recurring value; it does not measure recognized revenue, profit, customer retention, or overall business quality. Document the inputs, apply consistent rules, and use evidence-based comparisons for context.

Frequently Asked Questions
The key ARR answers are straightforward: normalize recurring plans, exclude one-time items, and interpret the result in context.
How do you calculate ARR from MRR?
Multiply total normalized MRR by 12. First include only active recurring plans, convert annual contracts into monthly equivalents, add all eligible monthly values, and then annualize the total.
Do annual contracts count in ARR?
Yes. Annual contracts count in ARR when they are active recurring contracts, but their value should be divided by 12 when calculating MRR. A $1,200 annual contract contributes $100 in normalized MRR and $1,200 in ARR.
Should setup fees count in ARR?
No. A setup fee is a one-time charge, so it should remain outside both MRR and ARR. The calculator excludes it even when it appears on the same invoice as a recurring subscription.
What is a good ARR for a startup?
There is no universal good ARR threshold. The answer depends on the business model, stage, contract quality, costs, retention, and the purpose of the comparison. ARR alone does not prove profit or success.
