Definition
MRR means Monthly Recurring Revenue: the recurring subscription revenue you expect from active customers in a given month. It is a standard operating metric for subscription businesses because it updates quickly and connects to retention and expansion.
Common components
- New MRR: from new customers.
- Expansion MRR: upgrades, more seats, add-ons.
- Contraction MRR: downgrades, seat reductions.
- Churned MRR: cancellations and lost recurring revenue.
MRR formula and monthly movement
A practical bridge is: ending MRR = starting MRR + new MRR + expansion MRR - contraction MRR - churned MRR. The bridge explains why MRR changed; it does not by itself forecast what happens next month.
MRR is not cash collected
MRR is a recurring run-rate metric. Cash collections can be lumpy because of annual prepayments, billing dates, refunds, credits, and payment terms, so cash collected should not be substituted for MRR.
Common mistakes
- Including one-time revenue in MRR.
- Mixing revenue recognition with billing/cash timing.
- Changing definitions month-to-month (breaking trend analysis).
- Reporting the ending MRR without showing new, expansion, contraction, and churned MRR.
Compare it with
- MRR vs ARR: MRR is the monthly recurring base; ARR is usually MRR x 12 for a monthly subscription business.
- MRR vs cash collected: MRR is a run-rate; cash depends on billing timing, prepayments, refunds, and payment terms.
Measured as
- Track ending MRR for the period and reconcile it with new, expansion, contraction, and churned MRR.
- Keep the same recurring-revenue policy, discount treatment, and customer scope from month to month.
Misused when
- When annual prepayments, one-time services, or non-recurring fees are counted as monthly recurring revenue.
- When cash collected or recognized revenue is used as a replacement for MRR.
- When the total is reported without a monthly movement bridge.
- Including one-time revenue in MRR.
- Mixing revenue recognition with billing/cash timing.
- Changing definitions month-to-month (breaking trend analysis).
- Reporting the ending MRR without showing new, expansion, contraction, and churned MRR.
Operator takeaway
- MRR is a fast operating signal, but retention and expansion determine whether the base is durable.
- Use the MRR waterfall before interpreting a change as growth, pricing impact, or churn improvement.
Next decision
- Use the MRR calculator for a current total, then use the MRR forecast and waterfall tools when the decision depends on future movement.
- Quantify the impact with MRR Calculator if you need to turn the definition into an operating assumption.
- Read MRR: what it means (and how to track it cleanly) if the decision depends on interpretation, policy, or trade-offs beyond the raw formula.
