Key takeaways
- AOV = total revenue ÷ orders—segment before you optimize a blended average.
- Raising AOV only helps unit economics when variable cost does not rise one-for-one.
- Free shipping thresholds and bundles are the usual levers; discounting is the lazy one.
- AOV sits at the top of contribution margin, LTV, and CAC payback—move it with margin in view.
- Model AOV lifts in the Ecommerce Simulator and confirm conversion does not collapse.
Definition
AOV (average order value) — total revenue divided by the number of orders in the same period. It answers: when someone checks out, how big is the basket on average?
AOV formula
AOV = Total revenue ÷ Number of orders
Use the same date range and revenue definition throughout. Net paid revenue after discounts is standard for DTC; wholesale or marketplace orders often belong in a separate AOV line. Exclude gift cards redeemed as revenue only if your finance team does—consistency beats perfection.
Example: $126,000 net sales ÷ 2,100 orders → AOV = $60.00. If mobile AOV is $52 and desktop is $71, a site-wide “raise AOV” project should start on mobile cart and PDP, not on a blended $60 target.
What AOV hides
- Margin mix — hero SKUs and accessories have different COGS. AOV can rise while gross margin falls if customers buy discounted bundles.
- Shipping subsidy — free shipping thresholds lift AOV but transfer margin to carriers. Net shipping belongs in contribution margin.
- Conversion trade-off — aggressive upsells or high thresholds can suppress checkout rate. Read AOV with conversion rate and revenue per visitor.
- Returns — higher AOV in apparel often means higher return dollars. See refund rate.
- Customer type — returning buyers inflate blended AOV; new-customer AOV drives CAC payback on first order.
Worked example: threshold vs discount
A home goods store runs at $58 AOV, 42% gross margin, $7 net shipping cost per order, and $41 blended CAC on new customers. First-order contribution ≈ $58 × 0.42 − $7 = $17.36. Payback ≈ 2.4 orders— tough if repeat is weak.
Option A — 15% sitewide sale: AOV drops to $54, conversion rises 8%. Contribution per order falls to ~$14. Payback lengthens; LTV may train discount behavior.
Option B — free shipping at $75: AOV rises to $67 among affected carts; 22% of orders qualify. Added COGS on attach items + $4 incremental shipping subsidy → contribution ≈ $21.50 on qualifying orders. Blended contribution rises if conversion holds.
AOV lifts that add proportional COGS or free-shipping cost can improve revenue while worsening contribution. Measure net margin per order, not AOV alone.

How to use AOV in the Ecommerce Simulator
In the Ecommerce Simulator, lock COGS, shipping, fees, CAC, and conversion. Increase AOV $5–$15 and watch contribution per order, payback in orders, and monthly cash. Try margin-first when AOV tactics are really margin tactics in disguise.
- Model a $75 free-shipping threshold vs flat 10% off.
- Add a bundle with +$12 AOV and +$4 COGS—does payback improve?
- Stress-test conversion −5% if the cart feels pushy.

- LTV — AOV × repeats over time.
- CAC — payback uses contribution per order, not raw AOV.
- ROAS — scales with AOV at constant conversion.
Back to the ecommerce glossary. AOV is the top line of every order-level model—raise it with margin, conversion, and repeat in the same breath.
