Unit Economics & Contribution Margin
Unit economics refers to the direct revenues and costs associated with a single unit of a product or service, helping businesses assess profitability on a per-unit basis. Contribution margin is the amount remaining from sales revenue after variable costs are deducted, indicating how much each unit contributes to covering fixed costs and generating profit. Together, these metrics are crucial for evaluating business sustainability, pricing strategies, and scalability.

❓ Frequently Asked Questions
What is unit economics?
Unit economics analyzes the direct revenues and costs for a single unit of a product or service to determine if selling that unit is profitable on its own.
What is contribution margin?
Contribution margin is the revenue per unit minus the variable cost per unit; it shows how much each unit contributes to fixed costs and profit.
How do you calculate contribution margin per unit?
Subtract variable costs per unit from price per unit; you can express it as a dollar amount or as a percentage (CM ratio = CM / price).
What is the difference between fixed and variable costs in unit economics?
Variable costs change with volume (materials, direct labor); fixed costs stay the same per period (rent, salaries). Unit economics focuses on variable costs to compute contribution margin.
How can unit economics inform pricing and scaling decisions?
If the per-unit contribution margin covers fixed costs at projected volumes, the product is scalable; if not, you may need price adjustments or cost reductions.
