Frequently asked questions
What is MRR?
Monthly Recurring Revenue is the normalised, predictable revenue from your subscriptions each month. It’s the core health metric for any subscription business.
What is ARPA?
Average Revenue Per Account — your total MRR divided by the number of paying accounts. Multiply it by your customer count to get MRR.
How is ARR different from MRR?
ARR (Annual Recurring Revenue) is simply MRR multiplied by 12 — the same recurring revenue expressed on a yearly basis.
How do I calculate MRR for my SaaS?
Multiply your number of paying customers by your average revenue per account (ARPA): MRR = customers × ARPA. This MRR calculator does it instantly and also shows your annual recurring revenue (ARR) and quarterly figures.
How do I convert MRR to ARR?
Annual Recurring Revenue is simply your Monthly Recurring Revenue multiplied by 12 (ARR = MRR × 12). Enter your customers and ARPA above and this calculator shows MRR and ARR side by side.
How do I grow my MRR?
MRR grows through more customers (new signups), higher ARPA (upsells, price increases, add-ons) and lower churn (keeping existing customers). Because MRR = customers × ARPA, improving either lever compounds — and reducing churn protects the base you already have.
Does MRR include one-time fees?
No. MRR counts only predictable, recurring subscription revenue. Leave out one-time setup charges, professional services and usage overages — normalise annual plans to a monthly figure (annual price ÷ 12) so everything is on the same monthly basis.
Is my data sent anywhere?
No. Everything is calculated in your browser with JavaScript — nothing you enter is uploaded.
