If you run a subscription business, Net Revenue Retention (NRR) is the single metric that tells you whether your existing customer base is growing or quietly shrinking — independent of new sales. A company can have a leaky bucket of new logos coming in the front door while existing accounts churn and downgrade out the back. NRR is what exposes that.
What Is Net Revenue Retention?
Net Revenue Retention measures the percentage of recurring revenue you retain from your existing customer base over a given period, including expansion (upsells, cross-sells) and contraction (downgrades, churn) — but excluding revenue from new customers.
An NRR above 100% means your existing customers are growing their spend faster than they're churning or downgrading. Below 100% means your existing base is shrinking, even if new sales make total revenue look fine on paper.
The NRR Formula
NRR = (Starting MRR + Expansion − Contraction − Churn) / Starting MRR × 100
A Practical Example With Numbers
Say your company starts the quarter with $500,000 in Monthly Recurring Revenue (MRR) from existing customers.
Quarterly NRR Breakdown — Example Company
Illustrative quarterly movement for a company starting at $500K MRR
Using the formula:
NRR = ($500,000 + $45,000 − $18,000 − $32,000) / $500,000 × 100
NRR = $495,000 / $500,000 × 100
NRR = 99%
Even with $45,000 in expansion revenue, this company is sitting at 99% NRR — just under the break-even line. This is a common trap: expansion revenue feels good in a dashboard review, but if churn and contraction eat more than expansion adds, the base is still shrinking.
NRR Benchmarks: What's Actually Good in 2026?
Benchmarks vary meaningfully by customer segment and deal size. Here's how NRR typically breaks down across company types:
| Segment | Weak NRR | Solid NRR | Best-in-Class NRR |
|---|---|---|---|
| SMB-focused SaaS | Under 90% | 95-105% | 110%+ |
| Mid-market SaaS | Under 95% | 100-110% | 115%+ |
| Enterprise SaaS | Under 100% | 105-115% | 120%+ |
| PLG (product-led growth) | Under 95% | 100-115% | 125%+ |
Enterprise and PLG companies tend to post the highest NRR because expansion (seat growth, usage-based upsells) is baked into the product itself, rather than depending entirely on a sales team pushing renewals.
NRR vs. Gross Revenue Retention (GRR): What's the Difference?
This is one of the most common points of confusion, so it's worth being precise:
- GRR (Gross Revenue Retention) only counts churn and contraction — it excludes expansion entirely. GRR can never exceed 100%.
- NRR (Net Revenue Retention) includes expansion, so it can exceed 100%.
If your GRR is low but your NRR looks healthy, expansion revenue from a small group of accounts may be masking a real churn problem underneath. Always look at both numbers together, not NRR alone.
How to Improve Net Revenue Retention
- Fix onboarding first. Most churn and low expansion trace back to customers who never reached real value in the first 90 days.
- Build expansion into the product, not just the sales process — usage-based tiers, seat-based pricing, and feature gating create natural upsell paths.
- Segment your health score by expansion likelihood, not just churn risk, so CSMs know which accounts to push for growth versus which to protect.
- Track NRR monthly, not just quarterly — by the time a quarterly NRR report shows a problem, the accounts driving it may already be three months into disengagement.
Frequently Asked Questions
What is a good NRR for a SaaS company? Most healthy mid-market SaaS companies target 100-110% NRR. Best-in-class companies, particularly in enterprise and product-led growth, often exceed 120%.
Is NRR the same as churn rate? No. Churn rate only measures revenue or customers lost. NRR nets churn and contraction against expansion revenue, giving a fuller picture of how the existing base is trending.
Can NRR be over 100%? Yes — and it should be, ideally. NRR above 100% means expansion revenue from existing customers more than offsets churn and downgrades.
How often should NRR be calculated? Monthly is best practice for fast-moving SaaS companies, with quarterly and annual NRR reported for board and investor updates.
A rising NRR is one of the clearest signals that a product is actually solving a problem customers want to keep paying more for. A flat or declining NRR, even with strong new sales, is usually the earliest warning sign of a retention issue — long before it shows up in total revenue.
Net Revenue Retention isn't just a metric for investors. Tracked monthly and segmented by customer type, it becomes one of the most actionable numbers a CS or RevOps team has — a direct read on whether the business is compounding or just replacing what it loses.
