Accounting Gross Profit Margin (Per-Unit) Calculator
Calculate gross profit per unit, gross profit margin, markup, and total gross profit from a product's selling price and direct cost.
Overview
This per-unit gross profit margin calculator shows how much gross profit a product generates after its direct cost is deducted from its selling price. Enter the selling price, direct cost per unit, and units sold to estimate unit profit, margin, markup, and total gross profit.
How it works
Gross profit per unit equals the selling price per unit minus the direct cost per unit. Gross profit margin divides that per-unit profit by the selling price and expresses the result as a percentage. Markup instead compares profit with cost, so it will usually be higher than gross margin. The calculator multiplies per-unit figures by units sold to estimate total revenue and total gross profit.

Cost of Goods Sold per Unit
$30
Units Sold
100
Gross Profit per Unit
$20.00
The product produces $20.00 gross profit per unit and a 40.00% gross profit margin. Selling 100 units produces $5,000.00 in revenue and $2,000.00 in gross profit before indirect expenses.
Frequently asked questions
What is gross profit per unit?
Gross profit per unit is the selling price of one unit minus the direct cost of that unit. It shows the amount available to cover overheads and contribute to profit.
How do I calculate gross profit margin per unit?
Subtract the unit cost from the selling price, divide the result by the selling price, then multiply by 100. For example, a $20 profit on a $50 sale gives a 40% margin.
What is the difference between gross margin and markup?
Gross margin measures gross profit as a percentage of selling price. Markup measures gross profit as a percentage of cost. They use different denominators, so the percentages are not the same.
Should overhead costs be included in cost per unit?
For a standard gross profit calculation, use direct costs or cost of goods sold. Indirect costs such as rent and advertising are normally considered separately when calculating operating profit.
What does a negative gross profit margin mean?
A negative margin means the direct cost per unit is higher than the selling price per unit. Each sale would create a gross loss before indirect expenses.
Can I use this calculator for services?
Yes. Use the fee charged for one service as the selling price and the directly attributable delivery cost, such as billable labour or materials, as the cost per unit.
