Calculating the ROI of Your Shopify Bundle Programme

The Three ROI Drivers of a Bundle Programme

A Shopify bundle programme creates value through three mechanisms. First, immediate AOV uplift: bundle buyers spend more per order than non-bundle buyers. Second, incremental volume: the bundle incentive converts some visitors who would otherwise have bought nothing into buyers. Third, LTV improvement: bundle buyers, exposed to more products, return more frequently and spend more over their customer lifetime. A complete ROI analysis captures all three, not just the immediate AOV effect.

Measuring Incremental AOV

Compare the average order value of orders that include bundle products to the average order value of orders that do not, over the same period. The difference, multiplied by the number of bundle orders, gives you the gross revenue impact of the bundle programme. Subtract the total discount cost (sum of all bundle discounts applied) from this gross impact to arrive at the net incremental revenue from AOV improvement.

Measuring Incremental Volume

Estimating incremental volume requires a control period. Compare your conversion rate before bundle activation to the conversion rate after, controlling for traffic volume and seasonal variation. If your conversion rate increased after bundle activation, some portion of that increase is attributable to the bundle offer converting visitors who would otherwise have left without buying. This is the incremental volume contribution. See the conversion rate guide.

LTV Contribution

Run a cohort analysis comparing the 180-day LTV of bundle buyers to non-bundle buyers. If bundle buyers show a meaningful LTV premium, this premium represents additional long-term ROI beyond the immediate order impact. See the cohort analysis guide and install Bundle MixMatch free.
