Monthly Recurring Revenue (MRR)
Last updated September 2026
Monthly recurring revenue (MRR) is the total predictable revenue an agency collects each month from retainers and ongoing contracts, excluding one-time project fees. It is the metric that matters most for agency valuation and planning, because it shows revenue reasonably expected to repeat, not a snapshot inflated by a single large project.
MRR is the number that separates a stable agency from one that looks busy but is really just chasing the next project. It counts only the revenue an agency can reasonably expect to collect again next month, without closing anything new, the same distinction Stripe draws between recurring and total revenue.
01
How MRR is calculated
Add up every active client's recurring monthly fee, retainers, ongoing management fees, subscription-style service contracts, and exclude anything one-time: a website build, a rebrand, a single campaign. What remains is MRR, the baseline the agency can plan payroll and hiring against.

Why MRR matters more than total monthly revenue
- 01
It reveals whether growth is coming from repeatable relationships or one-off projects that will not recur
- 02
It is the metric buyers and investors weight most heavily in an agency valuation
- 03
It exposes the real impact of churn, since losing a retainer client removes MRR permanently, not just for one month
- 04
It supports realistic capacity planning, since staffing should track predictable revenue, not project spikes

MRR in a white label context
For a reseller, MRR should be tracked on both sides of the relationship: the MRR the agency collects from its clients, and the wholesale cost owed to the fulfillment partner each month. The spread between the two is the margin that makes the retainer worth running, and tracking both numbers separately, not just net profit, shows which client segments are actually the healthiest.
Agencies that grow MRR steadily, rather than in project-driven spikes, tend to have an easier time forecasting hiring and negotiating better wholesale rates with fulfillment partners, consistent with the 91% of agencies that now offer retainers as a stable revenue base, since consistent volume is worth more to a partner than sporadic large orders.
Tracking MRR by channel, not just in aggregate, shows an agency which services are actually building a durable base versus which ones churn out almost as fast as they come in. A rising MRR number that comes entirely from a handful of large accounts is a different, riskier story than the same number spread across many smaller clients.
