Accounting Average Order Value (Per-Unit) Calculator FAQ
Answers to common questions about net AOV, sales per unit, refund treatment, order counts, and calculator results.
This FAQ explains the inputs, formulas, assumptions, and interpretation of average order value and per-unit sales measures. The calculator provides estimates from the figures entered and does not replace accounting, tax, or financial guidance.
General average order value questions
Basic definitions and uses of the calculator's main metrics.
What does this average order value calculator measure?
It estimates net sales revenue, net average order value, average revenue per unit, average units per order, and refund rate from sales-period inputs.
What is net average order value?
Net average order value is net sales revenue divided by completed orders. Net sales are gross sales less refunds and returns.
What is average revenue per unit?
It is net sales revenue divided by total units sold during the same period.
What is average units per order?
It is the total units sold divided by the number of completed orders.
Inputs and calculation method
How the calculator uses sales, refunds, orders, and units.
Which sales period should I use?
Use any reporting period that is useful for your analysis, such as a week, month, quarter, or year, provided every input covers the same period.
Should cancelled orders be included?
No. Use completed orders consistent with the sales revenue and units sold entered.
How are refunds and returns used?
They are subtracted from gross sales to calculate net sales revenue and are divided by gross sales to calculate refund rate.
Why must units sold be entered separately from orders?
One order can contain several items. Separate unit data allows the calculator to measure revenue per unit and units per order.
What happens if gross sales equal refunds and returns?
Net sales become zero, so AOV and revenue per unit are zero when orders and units are positive. A refund rate of 100% results.
Interpretation and comparison
How to read the outputs without overstating what averages show.
Is a higher AOV always better?
Not by itself. AOV is a revenue measure and does not account for costs, margins, refund patterns, or the mix of products sold.
Why might AOV and revenue per unit move in opposite directions?
AOV is affected by both unit value and the number of units in each order. Larger baskets can increase AOV even if per-unit revenue falls.
Can I compare AOV across months?
Yes, when order definitions and the treatment of refunds, discounts, tax, shipping, and other sales components are consistent.
Does the refund rate show the number of returned orders?
No. It shows the value of refunds and returns as a percentage of gross sales, not the count of orders with returns.
Scope and limitations
What the calculator does not determine.
Does this calculator calculate profit per order?
No. Profit requires cost and expense information, which is not included in the AOV and revenue-per-unit formulas.
Should sales tax be included in gross sales?
Use the treatment that matches your reporting purpose and apply it consistently. The calculator does not determine the correct accounting or tax treatment.
Should shipping revenue be included?
It depends on how your sales figures are defined. Include or exclude it consistently when comparing results.
Are the results accounting advice?
No. The results are estimates based on the data entered and should be checked against your records and applicable accounting policies.
What is the formula for net average order value?
Net AOV = (gross sales − refunds and returns) ÷ completed orders.
