Bundle profit calculator

How to read the results

Gross profit here is the bundle price minus product costs, packaging, fulfilment and payment fees. Gross margin is that profit as a share of the bundle price.

Accountants often leave fulfilment and payment fees out of gross margin. They're included here because each one is a real cost of shipping that specific bundle, and leaving them out flatters the discount you can afford. If you want the stricter accounting figure, set those fields to zero.

Gross margin is not net profit

This calculator stops at the contribution from a single order. Net profit also has to cover advertising, returns, staff, software, rent and tax, none of which appear here. A bundle with a healthy margin can still lose money if it costs too much to sell.

Why there are two comparisons

A discount only pays for itself if it changes what the customer would otherwise have done, so the right baseline depends on your customers.

• One full-price order assumes the customer would have bought all the items at once anyway. The bundle then simply gives away the discount, so this number is negative whenever you discount.
• Separate full-price orders assumes they would have bought each item in its own order. The bundle saves repeated packaging, postage and fixed payment fees, which can outweigh the discount.

Neither covers a customer who would have bought only one item, which is the case bundles are usually meant to win. Compare your own average order data before and after launch if you can. The bundle pricing guide works through this with examples.

When products have different prices

The calculator assumes every product in the bundle has the same price and cost, which holds only for uniform ranges. In a true mix-and-match bundle customers can choose different items, so run it twice: once with your cheapest eligible product's numbers and once with your most expensive product's. Those two results are the range your margin can land in.
