ARPU vs ARPA: what is the difference?
ARPU and ARPA differ only in the denominator: users versus accounts. That small difference changes what the metric tells you and which motion it fits.
Confusing the two overstates or understates per-customer value. A 50-seat account and a 1-user account have very different ARPA even if their ARPU looks similar.
Short answer
ARPU is average revenue per user, dividing revenue by individual users. ARPA is average revenue per account, dividing revenue by companies or accounts. In B2B SaaS, ARPA is usually the better metric because you sell to accounts that contain many users, while consumer and seat-based products often lead with ARPU.
Key takeaways
- ARPU divides revenue by individual users.
- ARPA divides revenue by accounts or companies.
- B2B and account-based selling favor ARPA.
- Consumer and per-seat products often use ARPU.
Which one fits your business
If you sell to companies where one contract covers many users, ARPA reflects the real economics because your unit of sale is the account. If you sell to individuals or price per seat and want to understand per-person value, ARPU is the sharper lens.
Many B2B teams track both: ARPA for deal and pricing strategy, ARPU to understand adoption depth within accounts.
How Ardovo handles it
Ardovo reports both per-account and per-user revenue from the same data, so you never accidentally mix them. Rook flags when ARPA is rising while per-user revenue falls, a sign accounts are adding seats faster than they add value.
Frequently asked questions
What is the difference between ARPU and ARPA?
ARPU divides revenue by individual users; ARPA divides it by accounts or companies. The denominator is the only difference, but it changes what the number means for your motion.
Should B2B SaaS use ARPU or ARPA?
Usually ARPA, because the unit of sale is the account, not the individual. ARPU can still be useful to understand adoption depth, but pricing and deal strategy hinge on ARPA.
Are ARPU and ARPA ever the same?
Only when each account has exactly one user, as in some consumer or single-seat products. In multi-user B2B accounts, ARPA is always higher than ARPU.
