Contribution

Throughput Accounting is used to measure and optimise the flow of products or services in order to maximise throughput, which is the rate at which the system generates money through sales.
It focuses on identifying and managing constraints that limit the system’s throughput. The bottleneck that occurs. The thing that stops production.

In throughput, contribution refers to the increase in profit resulting from an increase in throughput.
It is calculated by subtracting the direct material costs directly related to sales from the revenue generated. The assumption is that all other costs are essentially fixed in nature.
Contribution is used to assess the profitability of different products or services and to make decisions regarding resource allocation and product prioritisation.
