How we calculate. ARPA = revenue ÷ average account base. See our methodology and accuracy policy .
Real-world scenario: A typical Telecom ARPA case uses service revenue 48000000 and average accounts 320000. Enter the same figures below to reproduce the worked path.
What is Telecom ARPA?
Account-level unit revenue. Distinct from ARPU (per subscriber/SIM) and from SaaS ARPU.
- Accounts = billing entities
- Use when SIMs per account vary
- Same period as revenue
The Formula
Worked Example
Common Use Cases
- B2B/enterprise: account yield
- Family plans: account vs SIM gap
- Pricing: account-level ARPU twin
Pro Tips
- Label ARPU vs ARPA clearly
- Don’t mix SIMs into the account denominator
- Pair with subscriber churn
| Scenario | When to use |
|---|---|
| Percent of a number | Finding a part of a whole (tax, tip, score) |
| Percent change | Comparing old vs new values |
