Product Bundle Pricing & Profit: bundle discount
The contribution difference shows whether bundle discount and incremental volume outperform separate sales.
Formula summary
- Primary formula
- period delta = base orders × bundle contribution difference + incremental orders × bundle contribution
Data used here
- The estimate uses your inputs and the general business formula documented in the methodology.
Decision checks
Stress-test the decision
Retest incremental volume and cannibalisation independently.
When this estimate can be misleading
- Results depend on the accuracy and consistent basis of your inputs.
- The planner does not predict demand, competitor behaviour or supplier terms.
- Use the result as educational business decision support, not accounting, tax or legal advice.
- The contribution difference shows whether bundle discount and incremental volume outperform separate sales.

How do I test a product bundle?
Set the bundle only where its expected attach volume covers the contribution surrendered per bundle.
Which planning assumptions should I stress-test?
