The Core Equation
Strategic Context
THE STRATEGIC VIEW
Net Dollar Retention (NDR) is the "Proof of Scale" metric for SaaS. While CAC measures acquisition, NDR measures value. An NDR above 120% is the hallmark of world-class companies like Snowflake and Datadog, signifying that growth is compounding organically within the existing base.
Operational Reality
THE POWER OF NET NEGATIVE CHURN
Net Dollar Retention is the only metric that accounts for "Net Negative Churn." When your Expansion Revenue (upsells, seat expansion) exceeds your Gross Churn, your NDR crosses 100%. This is the "Holy Grail" of SaaS, where the business grows even if you never hire another salesperson.
SEGMENTATION IS SOURCE
A single NDR number often hides the truth. Enterprise customers might have a 125% NDR, while SMB customers might have 85% due to higher mortality rates. Segment your NDR calculation by Customer Tier to identify which part of your product has true "Scalability DNA."
THE EXPANSION ARBITRAGE
High NDR companies build "Usage-Based" or "Seat-Based" triggers into their pricing. If a customer gets more value, you get more revenue automatically. If your pricing is "Flat Rate," you are capping your NDR and forcing yourself to rely entirely on new customer acquisition for growth.
