Decide whether a bundle improves contribution
Compare bundles with standalone orders and the products they displace.
Build both order scenarios
Two products together generate $100 at standalone prices and cost $55 to fulfill. A $90 bundle leaves $35 before ads rather than $45 if both items would have sold at full price. If the buyer would have ordered only one item, the comparison changes.
Estimate what the bundle replaces
Compare buyers who choose a bundle with typical standalone baskets and use an experiment where practical. Look for customers shifting from a higher-contribution combination. Include changes to returns and delivery costs.
Set the success metric before launch
Track total contribution across comparable groups, along with order volume and inventory effects. A higher bundle conversion rate may support another goal, such as introducing a new product. Name that goal and its cost explicitly.
