Step-by-Step Examples
Example 1
Standard Bundle
Items at 49/35/25 standalone, costs 22/14/11, bundle price 89.
- Standalone total = 109, cost total = 47
- Bundle margin = 89 − 47 = 42 (47.2%)
- Separate margin = 109 − 47 = 62 (56.9%)
- Effective discount = 18.3%
- Bundle must sell 47.6% more units to match contribution
✓ 47.2% bundle margin, 18.3% discount
Example 2
Light Discount
Items at 60/40 standalone, costs 25/18, bundle 92.
- Standalone = 100, cost = 43
- Bundle margin = 49 (53.3%)
- Separate margin = 57
- Discount only 8% — required volume lift 16.3%
✓ 53.3% margin, modest 8% discount
Example 3
Overly Aggressive
Items at 80/60 standalone, costs 45/38, bundle 95.
- Standalone = 140, cost = 83
- Bundle margin = 12 (12.6%)
- Separate margin = 57
- Bundle must sell 375% more units to match contribution
✓ 12.6% margin — discount too deep
Real-World Applications
Attach Rate
Bundles raise average order value by moving products customers would not have bought separately.
Inventory Movement
Bundling slow movers with strong sellers clears stock that would otherwise incur carrying cost or markdown.
Cannibalisation Test
The required volume lift shows whether a bundle adds sales or just discounts what would have sold anyway.
Perceived Value
A visible discount versus separate purchase drives conversion even when the absolute saving is modest.
Common Mistakes to Avoid
⚠️
Bundling products customers already buy together
If they were going to buy both anyway, the bundle is simply a discount on existing sales with no volume benefit.
⚠️
Discounting too deeply
As the third example shows, an aggressive bundle price can require several times the volume to match separate-sale contribution — rarely achievable.
⚠️
Ignoring the mix effect
A bundle that shifts customers from a high-margin item to a lower-margin combination can reduce total profit even while raising order value.
Frequently Asked Questions
How do I price a bundle? ▾
Set it below the sum of standalone prices to create visible value, but high enough that the required volume lift is realistically achievable.
What discount is typical for bundles? ▾
Commonly 10 to 25% off the combined standalone price. Deeper discounts require disproportionately more volume to justify.
How do I know if a bundle is worth offering? ▾
Compare the volume lift required to match separate-sale contribution against what you realistically expect. If the required lift is implausible, the bundle destroys margin.
Should slow-moving stock be bundled? ▾
It can be an effective way to clear inventory, and avoiding carrying cost or markdown often justifies a thinner bundle margin.
What is bundle cannibalisation? ▾
When customers who would have paid full price for items separately buy the discounted bundle instead, reducing revenue without adding volume.
