SaaS METRIC OF THE WEEK
Gross Dollar Retention (GDR) measures the percentage of recurring revenue retained from existing customers over a specific period (excluding any upsells or expansion revenue). It focuses solely on revenue lost due to customer churn and downgrades, providing insight into the stability of your customer base - high GDR indicates strong customer satisfaction and product value. To calculate GDR, subtract churned and downgraded revenue from starting MRR, then divide by starting MRR. For example, if you start with $1M MRR and lose $25K to churn and downgrades, your GDR is 97.5%.
