How are the results calculated?
Contribution per unit = selling price − variable cost.
Contribution margin = unit contribution ÷ selling price × 100.
Total contribution = contribution per unit × quantity.
Assumptions and limits
- Contribution is not net profit: fixed costs have not been deducted. Include the full variable cost per unit without counting any item twice.
- A percentage is undefined when its base is zero. The calculated amounts remain visible.

Using the tool and understanding your results
See what remains from sales after variable costs. Enter unit selling price, variable unit cost and quantity to calculate unit contribution, its percentage, total contribution and total sales. The result shows the amount available for fixed costs and profit.
How do I calculate contribution margin?
Contribution per unit is selling price minus variable cost per unit. Divide unit contribution by selling price and multiply by 100 for the contribution margin ratio. An SAR 100 price and SAR 60 variable cost give SAR 40 contribution and a 40% ratio.
Is contribution margin the same as net profit?
Contribution is the amount left after variable costs but before fixed costs. A total contribution of SAR 10,000 must still cover fixed costs and any other relevant period items before it becomes net profit.
How do I calculate total sales contribution?
Multiply contribution per unit by the number of units. An SAR 40 contribution across 250 units gives SAR 10,000 total contribution. Use a price, variable cost and quantity that refer to the same item.
