Why use this e-commerce contribution margin scenario calculator?
Estimate e-commerce contribution margin with editable commercial assumptions and a transparent browser-based calculation. The model subtracts direct and allocated costs from revenue to estimate operating contribution and contribution margin.
Inputs used in this model
- Revenue / contract value: default example 300,000
- Direct cost: default example 180,000
- Other allocated cost: default example 30,000
How to interpret the result
Contribution margin is sensitive to which costs are classified as direct or allocated, so keep the cost scope consistent across scenarios. Change the most uncertain inputs and compare multiple scenarios rather than relying on a single default case.
Example
Replace the sample figures with values from your own quote, contract, policy, cloud bill, payroll report or operating plan. Compare a base case with at least one higher-cost or lower-volume scenario.
Important note
