What this planner helps you decide
Best for
Owners allocating a scarce production or delivery resource across two products.
Outputs
Priority product, feasible units, resource use and total contribution.
Start here
Define the genuinely scarce resource and realistic demand limits for both products.
Use a different tool when: Do not use this to choose the highest-contribution use of a constrained operating resource; use Capacity Constraint Profit Planner for that decision. Use this tool to allocate scarce capacity to a profitable product mix.

Capacity-constrained Profit Mix: priority product
Total constrained contribution allocates the scarce resource to contribution per constrained unit within both demand limits.
Formula summary
- Primary formula
- priority = highest contribution per resource unit; allocate whole product units until demand or capacity is exhausted
Data used here
- The estimate uses your inputs and the general business formula documented in the methodology.
Decision checks
Stress-test the decision
Retest Product A demand limit and Product B demand limit as whole units per planning period.
When this estimate can be misleading
- Results depend on complete, consistently classified inputs.
- Demand, timing, quality and strategic fit remain separate decisions.
- This is educational business decision support, not accounting, tax, legal or financial advice.
- Total constrained contribution allocates the scarce resource to contribution per constrained unit within both demand limits.
