Summary: Calculate NRR and gross revenue retention from one cohort, and see what the same customers are worth in three years with no new acquisition.

NRR above 100% means your existing customers are worth more this year than last, with no new acquisition at all. That single property is why it is the first metric investors ask about.

## Summary

Above 100% the customer base grows on its own. GRR strips out expansion and shows pure retention. 110%+ is strong; 120%+ is best-in-class. The most common error is including new customers in the cohort.

## NRR versus GRR

**What each measures**

|  | Includes expansion | Can exceed 100% | Tells you |
| --- | --- | --- | --- |
| NRR | Yes | Yes | Whether the base grows on its own |
| GRR | No | No | How much you keep before upsell |

Both matter, and reporting only NRR is a common way to flatter a retention problem. A company with 115% NRR and 80% GRR is losing a fifth of its customers and covering it with expansion from the rest — impressive, and fragile if expansion stalls.

## Benchmarks

**Typical NRR by segment**

| Segment | Median NRR | Strong |
| --- | --- | --- |
| Consumer | Under 90% | 100% |
| SMB SaaS | 95–100% | 110% |
| Mid-market | 100–110% | 120% |
| Enterprise | 110–120% | 130%+ |

> **Why it compounds so hard:** At 120% NRR a cohort worth $100,000 today is worth roughly $173,000 in three years with no new customers. At 90% it decays to about $73,000. Same starting point, a 2.4× difference in outcome.

## The mistake that inflates it

Including customers acquired during the period. NRR measures one cohort over time — the customers you had twelve months ago, and what that same group is worth now. Adding new customers to the numerator produces a number that is not NRR and is always higher.

## How to raise it

- **Give the product room to grow with the customer** — seats, usage, or capability tiers.
- **Reduce involuntary churn**, which subtracts from NRR without anyone deciding to leave.
- **Land smaller, expand deliberately.** A customer who starts at the top tier has nowhere to go.
- **Price on a value metric that grows** with the customer's own success.

**Stop losing revenue to failed cards** Involuntary churn subtracts from NRR every month, quietly. — [See pricing](https://www.paydude.io/pricing)

## Frequently asked questions

### What is a good NRR?

Above 100% is the threshold that matters — it means the base grows without new customers. 110% is strong, 120%+ is best-in-class. SMB products typically sit near 100%; enterprise products with seat-based expansion routinely exceed 120%.

### What is the difference between NRR and GRR?

NRR includes expansion revenue and can exceed 100%. GRR excludes it and never can — it measures pure retention. Reporting only NRR can hide a real churn problem being masked by upsell.

### How do I calculate NRR correctly?

Take the MRR of the customers you had twelve months ago, add their expansion, subtract their contraction and churn, then divide by the starting figure. Customers acquired during the period must be excluded entirely.

### Why do investors care about NRR most?

Because it separates growth from acquisition. A company with 120% NRR grows 20% a year even if it never signs another customer, which makes its revenue far more predictable and far more valuable per dollar.
