Bundle Margin Calculator

Bundles can lift AOV and still quietly damage the order if discount, fulfilment, and fee drag are not held in the same view. Use this calculator to see what the bundle actually leaves after the bundle logic is applied.

Compare bundle discount against real retained profit

Calculate bundle margin

Enter the normal unit price, bundle size, discount rate, product cost, fee rate, fulfilment, and extra packaging. The result shows how much the bundle really leaves once the order is sold as a discounted pack instead of as separate units.

Unit selling price Normal list price per unit before bundling. Units in bundle How many units are sold inside the bundle. Bundle discount % Discount applied against the separate list total. Product cost per unit Direct product or sourcing cost per unit. Fulfilment cost per bundle Pick-pack and shipping burden for the whole bundle. Extra packaging cost Any added packing drag caused by bundling. Fee rate % Marketplace, store, or processor take on the bundle revenue.

Three bundle scenarios.

Formula

What the bundle model includes

Bundle selling price = (Unit price × Bundle units) × (1 - Discount rate)

Bundle gross profit = Bundle selling price - Fees - Product cost - Fulfilment - Extra packaging

Bundle economics get distorted when the team looks only at AOV lift and ignores what the discount plus operational drag does to the retained margin. This calculator keeps the bundle honest before it gets promoted harder.

Where bundles disappoint

Discount depth can outrun the shipping or fulfilment gain.
Bundles can raise AOV while quietly reducing profit per dollar sold.
Extra packaging drag gets missed because it feels operational, not commercial.

Useful next step

Once the bundle is clean, compare it against Shopify fees and payout margin to see whether the pack deserves its own landing page, campaign, or upsell flow.
