ARR Calculator
Calculate ARR metrics for ecommerce, SaaS, marketing, and operations.
This ARR (Annual Recurring Revenue) calculator finds a subscription business's annualized recurring revenue, either by multiplying MRR by 12 or by directly summing annual-equivalent values from all active subscriptions.
Enter your MRR (or subscription details), and the calculator returns your ARR.
Worked Calculation Examples
| Scenario | Result | Calculation Step |
|---|---|---|
| MRR of $10,000 | ARR = $120,000 | ARR = 10,000 × 12 = $120,000. |
| MRR of $25,000 | ARR = $300,000 | ARR = 25,000 × 12 = $300,000. |
The ARR Formula
ARR = MRR x 12. Because ARR is simply an annualized view of the same recurring revenue captured by MRR, the two metrics always move together - ARR is generally preferred for reporting to investors or board members who think in annual terms, while MRR is more useful for month-to-month operational tracking.
ARR Should Exclude One-Time Revenue
ARR is meant to represent only predictable, recurring revenue - one-time fees like setup charges, professional services, or non-recurring add-ons should be excluded from the calculation, since including them overstates the business's actual recurring revenue base and can mislead growth and valuation analysis.

Frequently Asked Questions
How do you calculate ARR?
Multiply MRR by 12: ARR = MRR x 12, or alternatively sum the annual-equivalent value of all active recurring subscriptions directly.
Should one-time fees be included in ARR?
No - ARR should reflect only predictable recurring revenue. One-time charges like setup fees or professional services should be excluded, since they don't represent ongoing recurring revenue.
Why do SaaS companies report ARR instead of just total revenue?
ARR isolates the predictable, recurring portion of revenue, which is generally considered a more reliable indicator of business health and growth trajectory for subscription companies than total revenue, which can include one-time or lumpy income.

What does the ARR Calculator calculate?
Calculate ARR metrics for ecommerce, SaaS, marketing, and operations. It is designed for fast browser-based calculations without sign-up, downloads, or manual spreadsheet setup.
What formula does this arr use?
The formula is: ARR = MRR × 12. ARR became the preferred SaaS metric for board-level and investor reporting because it presents recurring revenue on the same annual basis investors use for most other company valuation and comparison metrics, while MRR remains the operational metric of choice internally, since it surfaces month-to-month changes in new sales, expansion, and churn more immediately than a yearly figure would.
