ARPA (Average Revenue Per Account) Calculator
Enter your ARR (Annual Recurring Revenue) and active customer count to calculate ARPA, the average revenue per account. Includes an SMB / Mid-Market / Enterprise segment reference table.
ARPA customer segment reference table
| Segment | Typical ARPA (annual) | Typical sales motion |
|---|---|---|
| SMB | Under $1,000 | Self-serve — fully online signup minimizes sales cost |
| Mid-Market | $1,000–$25,000 | Inside sales — individual attention via phone/video calls |
| Enterprise | $25,000 and above | Field sales and dedicated customer success |
* The appropriate level varies widely by industry and product. Use these figures as general guidance only.
Tips
- If you don't have an exact ARR figure, MRR (Monthly Recurring Revenue) × 12 works as a reasonable approximation.
- Make sure your active customer count excludes churned customers — including them will understate your true ARPA.
- If your ARPA is far from your intended target segment, it may be a sign to revisit your pricing or your target customer profile.
- Combine this result with other SaaS metrics like money.saas.acv and cac_payback to help size how much you can afford to spend on customer acquisition (CAC).
Frequently Asked Questions
Side Note — Why SaaS companies talk about segments in terms of ARPA
A single ARPA figure matters so much because it reflects a SaaS company's core strategic question: who are we selling to? Two companies with identical $10 million in monthly revenue — one with an ARPA of $500/year (many customers) and another with an ARPA of $50,000/year (few customers) — need completely different organizations and go-to-market motions. The former must efficiently acquire large volumes of customers through marketing and product polish; the latter needs a dedicated sales team carefully closing a handful of large deals.
The SMB / Mid-Market / Enterprise split isn't just a company-size classification — it's also a practical line for which sales motion makes economic sense. Deploying costly field sales against a low-ARPA segment causes customer acquisition cost (CAC) to exceed lifetime value (LTV), which breaks the business model. Conversely, trying to sell to high-ARPA enterprise buyers through self-serve alone often fails to address decision-makers' concerns (security, customization requirements, etc.), leading to lost deals.
Many fast-growing SaaS companies follow a staged expansion path: validating the market early on with a low-ARPA, high-volume SMB model, then adding features that matter to Mid-Market and Enterprise buyers (SSO, audit logs, SLAs, etc.) as the business matures, gradually raising ARPA. Tracking ARPA over time is therefore also a useful way to check whether this "move upmarket" strategy is actually working.
