Preguntas Frecuentes
How do you calculate MRR and ARR?
MRR (monthly recurring revenue) = active customers × average revenue per customer per month. ARR (annual recurring revenue) = MRR × 12. They are the core metrics for any subscription business.
What is the difference between MRR and ARR?
They measure the same recurring revenue over different periods — MRR monthly, ARR annually. Early-stage and monthly-billed businesses tend to track MRR; later-stage and annually-contracted SaaS lead with ARR.
Should one-time fees count toward MRR?
No. MRR should only include predictable, recurring subscription revenue. One-time setup fees, services, and overages are excluded so the number reflects sustainable run-rate revenue.
What is a good MRR growth rate?
It varies by stage, but early-stage SaaS often targets 10–15% month-over-month, while larger companies grow more slowly in percentage terms. Even 5–8% monthly compounds dramatically over a year.
How do I keep MRR accurate as I grow?
Calculate it from live customer and subscription data in your CRM rather than a spreadsheet. Manual tracking drifts as you add plans, upgrades, downgrades, and churn — and investors notice when the numbers do not reconcile.
