MRR = mensal + anual/12. ARR = MRR ร 12. ARPU = MRR / clientes.
MRR and ARR: the SaaS revenue metrics
MRR (Monthly Recurring Revenue) adds up every active monthly subscription you have: MRR = ฮฃ(active monthly subscriptions). ARR (Annual Recurring Revenue) is ARR = MRR ยท 12, or the sum of your annual contracts. Most teams break it down into New MRR from new customers, Expansion MRR from upgrades and upsell, Contraction MRR from downgrades, and Churned MRR from cancellations. Put those together and you get Net New MRR = New + Expansion โ Contraction โ Churn. Say 100 customers pay R$ 200/month: that is MRR R$ 20,000 and ARR R$ 240,000. When a contract is paid annually upfront, normalize it first โ a R$ 12,000/year deal is R$ 1,000 of MRR.
Context and benchmarks
When a SaaS company gets valued, ARR is usually the number people quote first; private rounds often land somewhere between 5รโ15ร ARR. VC investors lean on it, boards report against it, and growth plans like T2D3 (triple, triple, double, double, double) are framed around it. If you would rather not assemble the New/Expansion/Churn split by hand, tools like ChartMogul and Baremetrics do it for you.
FAQ
Do one-time fees count toward MRR? No. Leave out setup fees, professional services, and anything else that does not repeat. MRR is only the predictable recurring subscriptions.
MRR or ARR โ which should I report? MRR fits day-to-day operational tracking; ARR is what comes up with investors and in valuation talks. Since one is just the other times 12, you are looking at the same thing through a different lens.
How do I treat annual prepayments? For MRR, divide the annual contract by 12 to get the monthly equivalent and recognize the revenue as it is earned. The cash you collected upfront sits as deferred revenue; it is not the MRR for that one month.

Calculate your SaaS MRR and ARR
In a subscription business, recurring revenue is the number that rules all the others. MRR measures that revenue month by month, and ARR is the yearly read of the same thing. Together they tell you how a SaaS is doing, and the calculator consolidates both from your monthly and annual subscriptions.
Plans on different billing cycles get normalised into a real MRR, and from there comes the matching ARR projection. ARPU, the average revenue per user, comes along too. These are the numbers investors ask for, the ones that back decisions on growth, pricing and targets.
