Then, they’ll need to estimate the amount of activity or work that will be performed in that same time period. For this contribution margin example, we’ll say the marketing agency estimates that it will work 2,500 hours in the upcoming year.

Small companies typically use activity-based costing, while large organizations will have departments that compute their own rates. Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing. The allocation base (also known as the activity base or activity driver) can differ depending on the nature of the costs involved.

This is related to an activity rate which is a similar calculation used in Activity-based costing.
