Quick answer

What does the Monthly recurring revenue calculate?

How to use the Monthly recurring revenue

  2. Review the result and supporting figures as they update automatically.
  3. Check the formula and assumptions before using the estimate for a decision.

Inputs used

  • Starting monthly recurring revenue
  • New MRR this period
  • Expansion MRR this period
  • Churned MRR this period

Monthly recurring revenue formula

Ending MRR = starting + new + expansion − churned. ARR = ending MRR × 12.

Assumptions

  • Recurring means the same customer is billed again next month. One-off invoices stay out of these boxes.
  • ARR here is 12 times ending MRR. That is a planning annualization, not a GAAP revenue total and not cash collected.

Practical guide

Monthly recurring revenue example and edge cases

Monthly recurring revenue is the run-rate you expect to bill again next month. Add new and expansion, subtract churned, and annualize the ending figure as 12 times that month.

Example: Twenty thousand, then a net add

Start the month at 20,000 of recurring revenue. New customers add 4,000. Expansions add 1,000. Accounts that left take 2,000 with them.

Calculated result$23,000.00ending monthly recurring revenue

Ending MRR is 23,000. ARR on this page is 276,000, which is 12 × 23,000. That is a planning annualization, not a GAAP year and not cash in the bank.

Example results use the default display profile. The calculator above follows your selected country and units.

How to read the result

  • Read ending MRR first. Net new MRR tells you whether the book grew this period.
  • ARR here is just 12 times the ending month. A seasonal business should not treat that as next year’s collected cash.

Edge cases worth checking

A large one-off invoice landed this month

Leave it out. Recurring means the same customer is billed again. One-off work belongs on a profit-margin page, not in MRR.

A customer prepaid a year

Count the monthly slice you will recognize each month, not the whole prepayment. Otherwise the starting month looks huge and the next eleven look empty.

Common mistakes

Check starting monthly recurring revenue

Recurring means the same customer is billed again next month. One-off invoices stay out of these boxes. Make sure this matches the number you enter.

Keep churned mrr this period consistent

ARR here is 12 times ending MRR. That is a planning annualization, not a GAAP revenue total and not cash collected. Use the same units and time period throughout the calculation.

Do not rely on one monthly recurring revenue scenario

Run a cautious case and an optimistic case. The range is often more useful than one exact-looking number.
