Net revenue retention, or NRR, measures how much recurring revenue a company keeps and grows from its existing customers over a period, after accounting for expansion, contraction, and churn. It answers a single sharp question: if you signed no new customers at all, would your revenue from the current base grow or shrink? An NRR above 100% means the base expands on its own; below 100% means it leaks faster than it grows.

The calculation works from the recurring revenue of a customer cohort at the start of a period, adjusted by what happens to that same group:

• Add expansion. Revenue gained from upgrades, added seats, or higher usage within the existing base.
• Subtract contraction. Revenue lost to downgrades and reduced commitments.
• Subtract churn. Revenue lost from customers who left entirely.
• Divide by the starting revenue. New-customer revenue is excluded deliberately, because NRR measures the existing base, not sales’ ability to win logos.

A company at 115% NRR grew its existing accounts 15% net of all losses; a company at 90% lost a tenth of its base before adding a single new customer.

NRR matters because it captures the compounding health of a business in one number. Strong retention means growth gets easier over time, since each year starts from a larger, expanding base rather than running to replace what churned. It is also one of the clearest signals of whether pricing and packaging are working: a base that expands naturally is usually one where price scales with the value customers receive, and a base that contracts often points to a structure that does not grow with the account.

That link to structure is where NRR becomes a pricing question, not just a retention metric. Expansion revenue depends heavily on the value metric: when the unit you charge by grows as the customer succeeds, accounts expand without a renegotiation and NRR climbs on its own. When the metric does not track value, expansion requires a fresh sales motion every time. Tiering, expansion paths, and upgrade triggers are all pricing and packaging decisions that show up directly in the NRR number.

For B2B and PE-backed companies, net revenue retention is among the most watched metrics in diligence and value creation, because it predicts how efficiently a business can grow. Improving it is often less about chasing new logos and more about fixing the pricing structure so the existing base expands the way a healthy one should.
