What NRR Tells an MSP Owner
NRR answers one question: does your client base grow on its own? Take the clients you had twelve months ago, add up what they pay you now, and divide by what they paid then. Above 100 percent means seat growth, new services and price increases outran every downgrade and cancellation, so the MSP grows even in a year when sales brings in no new logos.
That makes NRR the best single read on whether your agreements are built to expand. An MSP that prices per user or per device, and adds security and compliance services over time, has expansion built in. One that sells a flat monthly fee with no review clause has to win every dollar of growth from new clients. For current targets, see the Net Revenue Retention KPI.
How to Calculate It Without Fooling Yourself
- Fix the cohort first: only clients that were billing twelve months ago. Clients signed during the year belong in growth, not retention.
- Use recurring revenue only, the same number you track as MRR. Project fees and one-time hardware sales swing the result and hide what the agreements are doing.
- Include every movement for that cohort: added seats, new services, price increases, removed seats, dropped services and full cancellations.
- Divide the cohort's current recurring revenue by its recurring revenue a year ago.
The most common mistake is letting new clients leak into the cohort. The second is counting a price increase as expansion without noticing it also caused a cancellation six months later. Both make NRR look healthier than the book really is.
Reading NRR Beside GRR
NRR blends gains and losses into one number, which is exactly why it can mislead. Always read it with GRR, which counts only the losses. The pair tells you which story you are in.
| NRR | GRR | What it usually means |
|---|---|---|
| High | High | Clients stay and buy more. The healthy case. |
| High | Low | A few large expansions are covering steady losses. |
| Low | High | Clients stay but rarely buy more. Pricing or account management is flat. |
| Low | Low | Clients are leaving and not growing. Fix service before sales. |
What Moves It
The levers are mostly in account management, not the service desk. A regular QBR with the decision maker is where most expansion is found: new hires, a compliance requirement, an unprotected office. Annual price increases move it too, and the Raising Prices Without Losing Clients article covers how to do that without turning expansion into churn.
Buyers look at it for the same reason you should. A book that grows without new sales is worth more than one that has to be refilled every year, which is part of how much your MSP is worth.
Common Questions
Should price increases count toward NRR?
Yes. NRR measures what the same clients pay now versus a year ago, so a price increase is expansion. Track it separately as well so you know how much growth came from price rather than new services.
Can NRR go below GRR?
No. NRR adds expansion on top of what GRR keeps, so it is always equal to or higher than GRR for the same cohort and period.
How often should an MSP measure NRR?
Measure it on a trailing twelve months, recalculated monthly or quarterly. A single month is too noisy because one cancellation or one big project can swing it.
Is NRR the same as net dollar retention?
Yes. Net dollar retention and NDR are other names for the same measure.
