The Metric That Separates Compounding from Treading Water
NRR above 100% means your existing customer base grows on its own, without a single new logo. At 110% NRR, you could stop all new customer acquisition and still grow 10% annually from expansion alone. Below 100%, you are on a treadmill: every new customer you acquire is partially replacing revenue that walked out the door. For a full breakdown of the metrics that drive retention, see the revenue operations guide. Public SaaS net dollar retention held steady at 110% for three quarters after falling from 2022 highs (High Alpha and OpenView, 2024), but private SaaS has compressed meaningfully, with many companies hovering near 100%.The Calculation
NRR = (Starting MRR + Expansion - Contraction - Churn) / Starting MRR x 100Start with your recurring revenue at the beginning of a period. Add upsells, cross-sells, and seat expansion. Subtract downgrades and cancellations. Divide by where you started. The result tells you whether your installed base is a growth engine or a leaky bucket. Segment this by cohort, product line, and customer size, the blended number hides the story.
Why Boards Obsess Over NRR
Existing customers generate a median 40% of new ARR, up five points in a year (Benchmarkit, 2025). Larger companies depend on it more: a median 58% for companies between $50 million and $100 million in ARR, and 67% above $100 million. Investors know that acquiring new customers is expensive and getting more so. A company with 120% NRR needs far less new-logo sales capacity to hit the same growth targets as a company at 95% NRR. That difference shows up directly in pipeline coverage requirements, sales headcount planning, and ultimately valuation multiples.NRR Benchmarks by Company Size
The median SaaS company sits just above 100%. Benchmarkit's 2025 benchmarks put median NRR at 101%, and note that keeping and expanding existing customers is getting harder. High Alpha's 2025 guidance sets good and great marks by ARR band:| ARR band | Good NRR | Great NRR |
|---|---|---|
| Under $1M | 100% | 110% |
| $1M to $5M | 100% | 110% |
| $5M to $20M | 105% | 120% |
| $20M to $50M | 103% | 112% |
| Over $50M | 102% | 107% |
How Do You Calculate NRR from a Revenue Waterfall?
Build a monthly ARR waterfall and NRR sits two lines away from GRR. Here is a made-up company that starts with $10,000,000 in ARR:| Line | Hypothetical example |
|---|---|
| Beginning ARR | $10,000,000 |
| Churned customer, churned product and product decrease ARR | -$900,000 |
| New product and increased product ARR from existing customers | +$1,000,000 |
| New customer ARR (excluded from NRR) | +$1,200,000 |
| Ending ARR | $11,300,000 |
How Do You Forecast NRR?
It depends on how you price. A seat-based business can forecast from contracts, seats, price and renewals. A usage-based business cannot, because revenue follows how customers behave. Forecast what drives usage first, such as past usage, customer growth and product adoption. Then turn that usage into revenue. Last month's usage alone will mislead you.The Levers That Actually Move NRR
Expansion revenue is the fastest lever, but gross retention is the foundation. You cannot expand your way out of a churn problem. Start by understanding why customers leave, is it product gaps, poor onboarding, or wrong-fit customers being sold in the first place? Once gross retention is stable above 85-90%, invest in expansion motions: usage-based pricing, seat expansion triggers, and upsell paths tied to customer maturity. Track NRR alongside quota attainment to ensure your team is balancing new-logo acquisition with base growth.Frequently Asked Questions
How do you calculate net revenue retention?
Start with beginning ARR from existing customers. Add expansion, then subtract churn and contraction. Divide by beginning ARR. New customers stay out of the calculation, which is why NRR measures the installed base alone.
What is the difference between NRR and GRR?
NRR includes expansion from existing customers and can run above 100%. GRR counts only what you keep, so it tops out at 100%. A healthy business needs both, since expansion can hide a churn problem for a while.
What is a good NRR for SaaS?
Benchmarkit's 2025 benchmarks put the median at 101%. High Alpha's 2025 guidance varies by size: 100% to 105% counts as good and 107% to 120% as great, with the bar highest for companies between $5 million and $20 million in ARR.
How much new ARR comes from existing customers?
In Benchmarkit's 2025 benchmarks, expansion is a median 40% of new ARR, up five points in a year. Larger companies lean on it more: a median 58% for companies between $50 million and $100 million in ARR, and 67% above $100 million.
What does NRR below 100% signal?
It means your existing customers shrank as a group. Churn and downgrades outweighed expansion, so new customers are partly replacing revenue that left before they can add growth.
