What it is
Expansion / upsell rate tracks revenue growth from the existing customer base — specifically upgrades, additional seats, and cross-sells — excluding new logo revenue. The formula is expansion ARR (upgrades + seats + cross-sell, excluding new logos) divided by total new ARR.
How to calculate it
Sum all incremental ARR booked from current customers in a period — seat expansions, tier upgrades, and cross-sell — then divide by total new ARR booked (new logos plus that expansion). Express as a percentage.
Why it matters
Expansion revenue is generally higher-margin and lower-CAC than new-logo revenue. For B2B SaaS and usage-based models, a rising expansion share signals that the product delivers durable value and that the land-and-expand motion is working. Above ~$50M ARR, expansion tends to dominate growth.
Benchmarks & pitfalls
OpenView research suggests expansion accounts for roughly 40% of new ARR across B2B SaaS companies, rising above 50% once companies exceed $50M ARR. These figures are directional — they reflect practitioner observation rather than a rigorous published study. Net Revenue Retention (NRR) is the more standardized metric for comparing expansion health across companies; this expansion percentage is best treated as an internal compass rather than a hard external benchmark.
