Calculating Gross Dollar Retention (GDR) is a crucial metric for any business that wants to understand how much revenue it retains from its existing customers. GDR is a measure of the total amount of revenue that a company retains from its customers over a specific period of time, usually a year, after accounting for any churn or lost revenue. In this article, we will explain what GDR is, why it is valuable to calculate, and how to calculate it.

## What Is Gross Dollar Retention?

Gross Dollar Retention is a metric that measures the percentage of revenue that a company retains from its existing customers over a specific period of time. It takes into account the revenue that a company loses due to customer churn, cancellations, or downgrades. GDR is an important metric for companies that rely on recurring revenue, such as subscription-based businesses, because it helps them understand how much revenue they can expect to generate from their existing customer base.

GDR is calculated by dividing the total revenue generated from existing customers at the end of a specific period by the total revenue generated from those same customers at the beginning of that period. The resulting percentage is the GDR for that period. For example, if a company generated \$100,000 in revenue from its existing customers at the beginning of the year and \$120,000 at the end of the year, its GDR for that year would be 120%.

## When Is It Valuable To Calculate Gross Dollar Retention?

Gross Dollar Retention is valuable to calculate for any business that wants to understand how much revenue it retains from its existing customers. It is particularly important for businesses that rely on recurring revenue, such as subscription-based businesses, because it helps them understand how much revenue they can expect to generate from their existing customer base. GDR is also useful for businesses that want to identify areas where they can improve customer retention and reduce churn.

By calculating GDR, businesses can identify which customers are most valuable and which ones are at risk of churning. They can then take steps to retain those valuable customers and reduce churn. For example, businesses can offer loyalty programs, personalized customer experiences, and proactive customer support to retain their most valuable customers.

In conclusion, Gross Dollar Retention is a crucial metric for any business that wants to understand how much revenue it retains from its existing customers. By calculating GDR, businesses can identify areas where they can improve customer retention and reduce churn, which can ultimately lead to increased revenue and profitability.
