Average Order Value Lift Calculator

Enter the base and new AOV to get the lift.

Result

10.42%
$6.50

How it is calculated

The tool compares two average order values (AOV), each being revenue divided by the number of orders for a period or test group. lift amount = new − base and lift % = (new − base) ÷ base × 100. The base AOV must be above zero, because it is the denominator. The new AOV may be lower than the base, in which case both results are negative and show a drop. Amounts are in US dollars with two decimals and the percentage has two decimals. The tool only compares the two numbers you give it: it does not test whether the difference is statistically reliable, and it ignores any change in the number of orders.

Worked example

A shop's average order was $62.40. After adding a "frequently bought together" bundle, the test group averaged $68.90. Step 1: lift amount = 68.90 − 62.40 = $6.50. Step 2: lift % = 6.50 ÷ 62.40 × 100 = 10.42%. The tool shows a lift of 10.42% and $6.50 per order. Before rolling out, check that fewer shoppers did not complete checkout, since a higher AOV with fewer orders can reduce total revenue.

Common mistakes

  • Computing each AOV from different periods, such as a holiday week against a normal week, so the lift reflects seasonality rather than the tactic.
  • Dividing the dollar lift by the new AOV instead of the base AOV, which understates the percentage (6.50 ÷ 68.90 is only 9.43%).
  • Judging success by AOV alone: if the bundle lowers conversion, total revenue per visitor may still fall.
  • Letting a few very large orders sit in a small test group, which can create a lift that disappears with more data.
  • Entering revenue totals instead of per-order averages; both fields expect the average value of one order.

About this calculator

Average order value (AOV) is total revenue divided by number of orders — one of the core metrics ecommerce teams watch alongside conversion rate and traffic. The lift from a specific tactic (a product bundle, a free-shipping threshold, a "frequently bought together" upsell) is calculated two ways: the dollar lift (new AOV − base AOV) and the percentage lift ((new AOV − base AOV) ÷ base AOV × 100), since a $5 increase means something very different on a $30 cart than on a $300 cart.

Ecommerce merchandisers, growth marketers, and CRO (conversion-rate-optimization) teams use this figure to justify a bundling or upsell strategy before rolling it out storewide, and to A/B-test one offer against another using a single comparable number rather than raw revenue, which is skewed by traffic volume.
