Frequently Asked Questions
How is MRR calculated?
Start with the sum of all monthly subscription fees, add expansion revenue from upgrades, subtract contraction from downgrades, and remove churned revenue. The result is net MRR, the clearest single measure of subscription health.
What is the difference between MRR and ARR?
ARR is simply MRR multiplied by 12. MRR suits month to month tracking and spotting short term shifts, while ARR is common for annual planning and fundraising conversations. The calculator gives you the monthly figure to build from.

Yes. It is free after creating a Brainito account, so you can recalculate every month in 2026 and keep a consistent record of how your recurring revenue is compounding over time.
