How the numbers shift across typical situations for this calculator:
| Scenario | Cost per unit |
|---|---|
| $12,000 / 800 | $15.00 |
| $50,000 / 2,500 | $20.00 |
| $3,200 / 150 | $21.33 |
| $240,000 / 20,000 | $12.00 |
How This Calculator Works
Enter the total production cost for a period — fixed costs plus variable costs — and the number of units produced. The calculator divides one by the other to give the cost per unit, the floor below which a sale loses money.
The Formula
Cost per Unit
Total Amount is the full cost or price, Quantity is the number of units it covers
Worked Example
A run that costs $12,000 and produces 800 units has a cost per unit of $15. Any selling price above $15 contributes margin; any price below it sells the unit at a loss.
Key Insight
Cost per unit falls as volume rises, because fixed costs spread over more units. That is economies of scale — and it is why a price that loses money at low volume can become profitable once production grows.
Frequently Asked Questions
What is cost per unit?
It is the total cost of production divided by the number of units made. It tells you the minimum price at which a unit can be sold without a loss.
What costs should I include?
Include both fixed costs, such as rent and salaries, and variable costs, such as materials. A figure that omits fixed costs understates the true cost of a unit.
Why does cost per unit fall as volume rises?
Fixed costs do not change with volume, so spreading them over more units lowers the share each unit carries. That is the essence of economies of scale.
How does cost per unit set the price?
It is the floor. The selling price must exceed it to make a profit; the gap between price and cost per unit is the margin on each sale.
Is this the same as marginal cost?
No. This is average cost per unit. Marginal cost is the cost of producing one additional unit, which can differ once fixed capacity is already covered.

Methodology & Review
Cost per unit is total production cost divided by units produced. Total cost should include both fixed and variable costs for the period, so the figure reflects the full cost of a unit.
