AOV measures the average revenue per order. It affects your allowable CPA at a given margin.

Definition

AOV measures the average revenue per order. It affects your allowable CPA at a given margin.

Formula

AOV = revenue / orders

Example

If you had $40,000 of revenue from 500 orders, AOV = $40,000 / 500 = $80.

How to use it

  • Use AOV with gross margin to estimate contribution per order.
  • Track AOV by channel and campaign (intent differs).

Common mistakes

  • Using AOV without accounting for refunds/returns (net revenue can be lower).
  • Comparing AOV across channels with very different product mixes.

Why this matters

This term matters because it affects how you interpret performance and make budget decisions. If you use inconsistent definitions or windows, ROAS/CPA can look "better" while profit gets worse.

Practical checklist

  • Write a 1-line definition for "AOV (Average Order Value)" that your team will use consistently.
  • Keep the time window consistent (weekly/monthly/quarterly) when comparing trends.
  • Segment results (channel/plan/cohort) before drawing big conclusions from blended averages.
  • Use a calculator that references this term (e.g., Paid Ads Funnel Calculator) to sanity-check assumptions.
  • Read the related guide (e.g., Paid ads funnel: CPM, CTR, CVR -> CPC, CPA, ROAS (with profit)) for context and common pitfalls.
