Multi-product Price Architecture: portfolio revenue
The weighted portfolio margin shows whether the expected product mix supports the target price architecture.
Formula summary
- Primary formula
- portfolio margin = total contribution ÷ total revenue
Data used here
- The estimate uses your inputs and the general business formula documented in the methodology.
Decision checks
Stress-test the decision
Run a lower-volume case for the higher-margin product before changing list prices.
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 weighted portfolio margin shows whether the expected product mix supports the target price architecture.
