Subscription Bundle Calculator
This calculator compares the economics of selling subscription items separately with offering them as a discounted bundle.
Merchandising teams can see customer savings, bundle revenue, total cost, and contribution margin before launching a curated box or multi-plan package.

Bundle price = Combined standalone price × (1 − Bundle discount rate)
Contribution per bundle = Bundle price − Product cost − Fulfillment cost
Contribution margin = Contribution per bundle ÷ Bundle price × 100
The model assumes every bundle has the same composition and does not include percentage payment fees, taxes, refunds, or fixed overhead.
What the result means
The main result is the customer-facing bundle price after applying the entered discount to the combined standalone price.
A positive contribution margin does not guarantee overall profitability; acquisition, overhead, refunds, and inventory risk also matter.
Given
A wellness bundle contains plans worth $64 separately, offers a 12% discount, costs $24.50 in products and $4.20 to fulfill, and sells 700 bundles.
Calculation
Bundle price = $64 × (1 − 0.12) = $56.32.
Contribution = $56.32 − $24.50 − $4.20 = $27.62.
Margin = $27.62 ÷ $56.32 × 100 = 49.04%.
Result
The bundle price is $56.32, saving customers $7.68 and producing $19,334 in period contribution.
Should shipping be included in fulfillment cost?
Include shipping when the business absorbs it. If customers pay shipping separately, analyze that revenue and cost consistently.
Can I enter a bundle discount of 100%?
Yes, but the bundle price becomes zero and contribution margin is not meaningful; the calculator displays 0% margin.
What if contribution is negative?
The bundle price does not cover the entered direct costs. Reduce the discount, change the contents, or lower fulfillment cost.
Does the standalone total include existing discounts?
Use the prices customers would otherwise pay for the same items. This makes the displayed savings understandable.
How is this different from average order value?
This calculator designs one bundle’s economics. AOV measures actual average revenue across completed orders.
