What is Net MRR Retention?
Net MRR Retention (NRR) — also called Net Revenue Retention or Net Dollar Retention — measures what percentage of last period’s recurring revenue you kept from existing customers, after accounting for upgrades, downgrades, churn, and reactivations.
An NRR above 100% means your existing customers are spending more than they were — expansion outpaces losses. Below 100% means you’re shrinking without new sales.
New business is deliberately excluded — NRR measures whether your existing base is healthy, not whether you’re acquiring.
The NRR formula
| Variable | What it captures |
|---|---|
| Starting MRR | Total MRR from existing customers at the beginning of the period |
| Expansion | Revenue increase from upgrades, add-ons, and seat additions |
| Reactivation | Revenue from customers who previously canceled and returned |
| Contraction | Revenue decrease from downgrades and reduced usage |
| Net Churn | Revenue lost from customers who canceled entirely — excluding same-period signups who left, since they were never in the starting base |

Benchmark My NRRWorked example
July 2026: Your existing customers started the month at $50,000 MRR.
| Movement | Amount |
|---|---|
| 3 customers upgraded plans | +$2,500 |
| 1 previously churned customer returned | +$800 |
| 2 customers downgraded | −$600 |
| 4 customers canceled fully | −$3,000 |
| Churn excludes $200 from a same-period signup who left (joined-and-churned). | |
At 99.4%, losses slightly outpaced expansion — you need new business to grow. An NRR above 100% would mean your existing customers alone are driving revenue growth.
What drives NRR above 100%?
Three levers move NRR above 100%:
- Usage-based pricing. As customers grow, they naturally pay more. The easiest path to high NRR.
- Seat expansion. Teams grow, seats increase, revenue follows.
- Upsell to higher tiers. Customers start on a lower plan and upgrade as they see value.
Companies with flat per-seat pricing and no upsell path structurally cannot exceed ~100% NRR. The pricing model determines the ceiling.
Cross-validation
NRR and GRR have been cross-validated against ChartMogul across multiple months. Results: exact or rounding-level match on all comparable months (within 0.04 percentage points), with one month showing a 1.3 percentage point gap due to differences in how each tool reconstructs historical plan amounts — a common divergence between state-comparison and event-sourced architectures.
How NRR feeds into your Health Score
NRR has a 20% weightin North Metric’s composite Health Score. Scoring maps linearly from 70% NRR (score = 0) to 120% NRR (score = 100). GRR adds another 20% weight. Together, retention metrics drive 40% of your overall health grade.
NRR vs GRR — when to use which
| NRR | GRR | |
|---|---|---|
| Includes expansion | Yes | No |
| Includes reactivation | Yes | No |
| Can exceed 100% | Yes | No (capped at 100%) |
| Best for | Overall business health, investor readiness | Measuring stickiness without upsell masking losses |
GRR shows the floor.If your GRR is 85%, you lose 15% of revenue every period from downgrades and churn alone. If your expansion engine slowed, 85% is where you’d land.
NRR shows the net. If NRR is 115%, your existing customers are growing your revenue 15% per period.
Use both. A company with 120% NRR and 70% GRR has a churn problem masked by aggressive upsell. A company with 105% NRR and 95% GRR has strong retention and modest expansion — healthier long-term.
Common NRR mistakes
- Including new business. NRR measures existing customers only. Adding new sales inflates the number and hides churn.
- Using end-of-period MRR as the denominator. The denominator is MRR at the start of the period. Using end-of-period double-counts expansion.
- Ignoring contraction. A customer going from $500/mo to $100/mo is an 80% revenue loss even though they didn’t cancel. Make sure your NRR includes downgrades.
- Mixing periods. Monthly NRR and annual NRR are different numbers. Be explicit about which you’re reporting.
- Not excluding same-period signups from churn. A subscription that started and ended within the same month was never in the starting cohort — including it as churn deflates your NRR unfairly.
SaaS NRR benchmarks
NRR benchmarks are segmented by MRR tier. Your NRR is scored against peers at your revenue level — top 25% (75th percentile or above) and bottom 25% (25th percentile or below).
| MRR Tier | Range | Bottom 25% | Median | Top 25% |
|---|---|---|---|---|
| Seed | < $10K | 98.2% | 99.1% | 100.0% |
| Early | $10K – $50K | 99.1% | 100.0% | 100.8% |
| Growth | $50K – $100K | 99.7% | 100.3% | 101.2% |
| Scale | $100K – $500K | 100.0% | 100.6% | 101.5% |
| Enterprise | $500K+ | 100.4% | 101.2% | 101.9% |

Benchmark My SaaSFrequently asked questions
What is a good NRR for SaaS?
Above 100% is best-in-class — it means existing customers grow your revenue without new sales. 90-100% is acceptable at early stage. Below 90% signals a retention or monetization problem. The right benchmark depends on your pricing model — usage-based companies structurally achieve higher NRR than flat-rate.
Is NRR the same as Net Dollar Retention?
Yes. Net MRR Retention, Net Revenue Retention, and Net Dollar Retention all refer to the same metric. The formula is identical — the naming varies by convention depending on the analytics tool. North Metric uses “Net MRR Retention” because MRR is the native unit of measurement for monthly SaaS operations.
Can NRR be above 100%?
Yes — and that’s the goal. NRR above 100% means expansion from existing customers (upgrades, seat growth, usage increases) outpaces revenue lost to churn and contraction. Your existing customer base is actively growing your revenue without any new sales, which is the strongest signal of product-market fit and pricing power.
How often should I measure NRR?
Monthly for operational tracking, trailing-twelve-month (T12M) for board reporting. Monthly NRR can be volatile — a single large upgrade or churn event can swing it several percentage points. T12M smooths the noise and reveals the real trend, making it the preferred format for investors and fundraising decks.
Why does North Metric exclude same-period signups from NRR churn?
NRR is a cohort metric — it measures retention of the starting cohort. A subscription that was never in the starting MRR base can’t churn from it. Including same-period signups as churn would deflate NRR unfairly, especially in periods with high trial activity.
