Net Revenue Retention

101.0%

What This Means

Above 100% means expansion revenue from existing customers is outpacing downgrades and churn, growth on top of a stable base.

The Formula

NRR = ((Starting MRR + Expansion MRR - Downgrade MRR - Churned MRR) / Starting MRR) × 100

Why It Matters

A company can post strong headline growth while its existing base is quietly shrinking underneath it, entirely masked by new sales. NRR strips that out, which is why investors treat it as one of the clearest single indicators of whether a product is actually sticky once customers are already inside it.

Example

A company starts the month with $100,000 in MRR, gains $8,000 from upgrades, loses $3,000 to downgrades, and $4,000 to churn. NRR is (($100,000 + $8,000 - $3,000 - $4,000) / $100,000) times 100, which equals 101%.

Frequently Asked Questions

  • Above 100% is generally considered healthy, and best-in-class SaaS companies often post 110% to 130%, meaning the existing base grows meaningfully even with zero new customers.

  • Gross revenue retention excludes expansion revenue and only measures how much of the starting base survives, capping out at 100%. NRR includes expansion, so it can exceed 100%.
