Dollar-Based Net Expansion Rate (DBNER)

The Dollar-Based Net Expansion Rate (DBNER) is a measure of how much a company's customer base is growing in terms of the value of the products or services it sells. It is calculated by dividing the total value of new business generated by the company over a given period of time by the total value of its existing business at the start of that period.

For example, let's say a company has existing customers who spend a total of $100,000 on its products or services each year. In a given year, the company adds new customers who spend a total of $50,000 on its products or services. The company's DBNER for that year would be 50%, since the new business it generated was equal to half of its existing business. This metric is useful for tracking a company's growth over time and comparing its performance to that of other businesses in the same industry.
