NDR
Net Dollar Retention
aka Trailing Twelve Month NDR
NDR measures the average percentage change in revenue over the first 12 months of a customer. It is the most cost-efficient way of accelerating revenue growth and value creation. Best-in-class SaaS businesses typically have net dollar retention rates above 110%, and many of the top performing SaaS IPOs of the past few years have had net dollar retention rates above 130%. Net retention below 100% means churn and downgrades were greater than any growth you enjoyed from the expansion of existing customers. [1] [2]
