Free Cross Sell Revenue calculator with clear step-by-step results.
Sizes the revenue a cross-sell adds to an existing customer base. Attach rate converts the base into buyers, repeat frequency turns a single purchase into annual revenue, and the per-customer figure is what makes the offer comparable against other uses of the same placement.
Cross-sell revenue
Revenue = base x attach rate x price x purchases per year
Revenue per customer
Per customer = total cross-sell revenue / customers in the base
Five to fifteen percent is typical for a relevant accessory shown at checkout. Category-adjacent recommendations in email or account pages usually land lower, at one to five percent.
Gross margin here. If the cross-sell needs its own picking, packing or support effort, subtract that separately before judging the offer.
