Bundle Pricing and Margin Calculator
List the items in the bundle with their costs and solo prices, then try a bundle price. The calculator shows the bundle's margin, the shopper's saving, and how it compares to selling the items separately.
Bundle margin
67.8%
$40.00 profit on a $19.00 cost. Sold separately the margin is 75.0% — the gap is what the bundle discount costs you.
Bundle discount
22.4%
What the shopper saves versus buying each item alone. Keep it visible on the page; an invisible discount sells nothing.

Why bundles work when discounts don't
A bundle raises the order value and moves more units per transaction, and the discount hides inside a new product instead of marking down your catalog. It's also the classic way to attach a slow mover to a best seller — the discount does a job instead of just costing margin.
Pricing the bundle
Anchor on the solo total and make the saving visible — a bundle that saves nothing sells nothing, and one that saves too much trains shoppers never to buy items alone. Check the margin line: the bundle should still clear your floor after the discount, including any extra packaging.

Frequently asked questions
How much discount should a bundle offer?
Enough to be visibly better than buying separately — often in the 10–20% range — but the right answer comes from your margin, not a benchmark. Price the bundle so the saving is obvious on the page and the margin line in this calculator still clears your floor.
How do I calculate bundle profit margin?
Sum the unit costs of everything in the bundle (plus any extra packaging), subtract from the bundle price for profit, and divide by the bundle price for margin. Comparing it to the separate-items margin shows exactly what the discount costs you per bundle sold.
Should I bundle my best seller with a slow mover?
It's one of the best uses of bundling: the best seller supplies the demand, the slow mover gets movement without a public markdown, and the combined margin often beats discounting the slow item alone. Make sure the pairing makes sense to the shopper, or the bundle will stall.
Do bundles increase average order value?
Yes — that's their main job. A shopper who came for one item leaves with three, and the discount costs you less than the extra contribution the added units bring. Track AOV and attach rate after launching one; a bundle nobody adds needs a better pairing or a clearer saving.
