Bundle Gross Margin (%) 69.2%
Break-Even Sales Volume 756 Bundles

Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Bundle Profit = Bundle Price - Combined COGS | Profit Uplift = (Bundle Profit × New Volume) - (Single Profit × Old Volume)

Step-by-Step Mathematical Derivation

1
A la Carte Unbundled Value

Combined Full Retail = Item A ($45.00) + Item B ($35.00) = $80.00.

2
Consumer Promotional Discount

Savings = $80.00 - $65.00 = $15.00. Discount % = ($15.00 / $80.00) × 100 = 18.75% ≈ 18.8% off.

3
Unit Profit Economics

Bundle Gross Profit = $65.00 - $20.00 COGS = $45.00. Gross Margin % = ($45.00 / $65.00) × 100 = 69.2%.

4
Baseline Comparison & Break-Even

Baseline profit on Item A alone (assuming $11 COGS) = $34.00 × 1,000 = $34,000. Break-even bundle volume = $34,000 / $45.00 = 756 bundles.

Frequently Asked Questions

Why do bundles improve marketing efficiency? +
Bundles immediately raise Average Order Value (AOV). Because shipping a two-item box costs almost the same as shipping a single item, bundling leverages fixed shipping and ad acquisition costs across more gross margin dollars.
What is the recommended discount percentage for bundles? +
Bundles typically perform best with a discount between 15% and 22%. Lower discounts fail to convert hesitant shoppers, while discounts above 25% unnecessarily erode contribution margins.
