ARPA Growth Calculator
ARPA growth is the cleanest signal of pricing power and expansion success. Calculate ARPA trajectory and decompose it into price increases, seat expansion, and product attach.

ARPA (Average Revenue per Account) growth is the cleanest signal of pricing power and expansion success. Best-in-class SaaS grows ARPA 15-30% YoY through expansion within existing accounts, price increases, and up-market mix shift. Bessemer Cloud 100 top quartile averages 18% ARPA growth.
Three Growth Levers
(1) Expansion within accounts: seat growth + product attach contributes 60-70% of ARPA growth in best-in-class SaaS. (2) Price increases: 5-10% annual list price increases compound to 27% over 3 years. (3) Up-market mix shift: net-new customers landing at higher ACV pulls the average up. Bessemer Cloud 100: companies with 18%+ ARPA growth use all three; companies with flat ARPA rely only on net-new and watch their average stagnate over time.
Diluted vs Accretive Lands
If new logos land at lower ACV than existing ARPA, your average dilutes — even with healthy expansion. Watch for this pattern: existing ARPA $30K, new lands at $15K, customer count grows 30% but ARR only grows 15%. Solution: either move new lands up-market through better ICP targeting, or commit aggressively to expansion timeline (90-day to value, 6-month upsell motion). Diluted ARPA at fast logo growth is a common Series B trap that surfaces only when investors normalize metrics.
