# Net revenue retention calculator: NRR and gross revenue retention

> Net revenue retention (NRR) = (starting recurring revenue + expansion − contraction − churned revenue) ÷ starting recurring revenue, measured on the same group of customers. Above 100% means existing customers grow revenue on their own. Gross revenue retention (GRR) leaves expansion out and can never exceed 100%; it shows how well you keep the revenue you already have.

## Example result (default inputs)

| Input | Value |
| --- | --- |
| Currency | USD ($) |
| Period | Year |
| Recurring revenue from existing customers at start | 100,000 |
| Expansion (upgrades, add-ons, seats) | 18,000 |
| Contraction (downgrades) | 4,000 |
| Churned revenue (cancellations) | 8,000 |

**Net revenue retention (NRR): 106%.** Net revenue retention is 106% for the year, and gross revenue retention is 88%.

Above 100%: expansion outweighs churn and downgrades, so revenue grows even without new customers.

| Metric | Value |
| --- | --- |

## How it is calculated

- **NRR**: (starting revenue + expansion − contraction − churn) ÷ starting revenue
- **GRR**: (starting revenue − contraction − churn) ÷ starting revenue
- **Annualised**: monthly rate^12 or quarterly rate^4

## NRR vs GRR

|  | Net revenue retention | Gross revenue retention |
| --- | --- | --- |
| Includes expansion | Yes | No |
| Can exceed 100% | Yes | No |
| Tells you | Whether the base grows on its own | How well you keep existing revenue |
| Commonly cited strong level | Above 100%; 120%+ for enterprise SaaS | Above 90% |

## Why investors care about NRR

With NRR above 100%, every cohort of customers is worth more each year, so growth compounds: new sales add to a base that is already growing.

NRR also shows product-market fit inside accounts — customers who expand are getting more value over time.

## Ways to raise NRR

- Price on a value metric that grows with the customer (seats, usage, locations).
- Add higher tiers and add-ons for advanced needs.
- Run customer success reviews that uncover expansion opportunities.
- Reduce downgrades by showing customers the value they get.

## FAQ

### How do you calculate net revenue retention?

Take recurring revenue from existing customers at the start, add expansion, subtract contraction and churned revenue, then divide by the starting revenue.

### What is a good NRR?

Above 100% is good; well above 110–120% is considered excellent, especially for products sold to larger companies.

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

Net dollar retention (NDR) is the same metric as net revenue retention, named after the currency.

### Should new customers be included in NRR?

No. NRR measures only customers who were already paying at the start of the period.
