Metrics
Expansion Revenue
Quick definition
Additional recurring revenue from existing customers through upsell, cross-sell, and seat or usage growth.
Expansion revenue is new recurring revenue earned from your existing customer base rather than from new logos, through upsells to higher tiers, cross-sells of additional products, and growth in seats or usage. It is the engine behind net revenue retention above 100 percent, where the existing base grows even before new sales. Because expansion customers are already acquired, expansion revenue carries a far lower CAC than new-logo revenue, which is why efficient SaaS companies build deliberate expansion motions and track expansion as its own line alongside new and churned revenue.
