MRR & ARR Calculator
Monthly & annual recurring revenue
Track your recurring revenue. Enter your paying customers and the average revenue each one pays per month to get MRR, ARR, and a 12-month ARR projection at your growth rate.
MRR vs. ARR
MRR (monthly recurring revenue) is your paying customers multiplied by average revenue per account (ARPU). ARR (annual recurring revenue) is just MRR × 12. 200 customers at $50/month is $10,000 MRR and $120,000 ARR. Add an expected monthly growth rate and the calculator compounds it across 12 months to project where ARR lands — a quick sanity check on a growth plan.
MRR & ARR Calculator: frequently asked questions
How do I calculate MRR?
Multiply your number of paying customers by the average revenue per account per month. Only count recurring subscription revenue, not one-off fees.
Is ARR just MRR times 12?
Yes — ARR is MRR × 12 for a steady book of business. The projection above instead compounds your monthly growth rate over the year.
