Expansion revenue

Expansion revenue is the increase in recurring revenue that comes from customers a company already has, rather than from new logos. It takes several forms: upselling to a higher plan tier, cross-selling an additional product, adding seats or usage within an existing account, or a price increase a customer accepts. It is tracked as one component of the monthly recurring revenue bridge alongside new, contraction, and churned revenue.

Expansion revenue is the piece that separates net revenue retention from gross revenue retention: GRR excludes it entirely and caps at 100%, while NRR adds it back in and can exceed 100% when expansion outweighs contraction and churn rate within the existing base. A company with weak new-customer acquisition can still grow overall revenue if expansion revenue from its installed base is strong enough.

Expansion revenue matters because it is usually cheaper to generate than new-customer revenue, since it does not carry the same acquisition cost, and strong expansion is a signal that a product is delivering enough value for customers to buy more of it over time. A common pitfall is engineering short-term expansion through pricing changes or bundling that customers later resist, which shows up as a spike in expansion revenue now and elevated contraction or churn later.
