What this calculation means
Contribution profit here means revenue minus direct costs minus the allocated share of common operating costs. It is an internal planning measure—not accounting, tax, or financial advice.
Equal allocation gives every product the same share. Revenue weighting assigns more of the pool to products that earn more, and falls back to an equal split when every product has zero revenue. Custom percentages reflect a deliberate judgment, such as a pre-launch product using most of a design tool; they must total 100%.
