Calculating net revenue retention is an important metric for any business that wants to understand how much revenue it is retaining from its existing customers. This metric is particularly valuable for subscription-based businesses, as it helps them understand how much revenue they are generating from their existing customer base, and how much they are losing due to customer churn.

## What Is Net Revenue Retention?

Net revenue retention is a metric that measures the amount of revenue a business is retaining from its existing customers over a given period of time. It takes into account the revenue generated from existing customers at the beginning of the period, as well as any revenue generated from upsells, cross-sells, and renewals during the period. It also takes into account any revenue lost due to customer churn during the period.

Net revenue retention is calculated by dividing the total revenue generated from existing customers during the period by the total revenue generated from those same customers at the beginning of the period. The resulting percentage represents the net revenue retention rate.

## When Is It Valuable To Calculate Net Revenue Retention?

Calculating net revenue retention is valuable for any business that wants to understand how much revenue it is retaining from its existing customers. This metric is particularly valuable for subscription-based businesses, as it helps them understand how much revenue they are generating from their existing customer base, and how much they are losing due to customer churn.

By calculating net revenue retention, businesses can identify areas where they can improve customer retention and increase revenue. For example, if a business has a low net revenue retention rate, it may indicate that customers are not finding value in the product or service, or that the business is not providing adequate customer support. By addressing these issues, the business can improve customer retention and increase revenue.

Overall, net revenue retention is a valuable metric for any business that wants to understand how much revenue it is retaining from its existing customers, and how it can improve customer retention to increase revenue.
