The Product Profit Estimator calculates how much profit one item or product line produces after unit costs, selling fees, shipping, and other per-order expenses are deducted from sales revenue. It is useful for online sellers, retail operators, and product managers who need a quick unit-economics check before changing a price or approving a promotion.
The result separates profit per unit from total profit and shows the margin earned on revenue. That makes it easier to compare products with different prices, identify cost pressure, and estimate how many sales are needed to reach a target contribution.
Use the customer-facing price before subtracting any product expenses.
Include acquisition or manufacturing cost, marketplace fees, and shipping or packaging paid per sale.
Use completed units sold for an actual period or a forecast volume for planning.
Compare total profit with profit per unit and margin to see whether volume or pricing drives the result.

Assumptions: The estimate excludes fixed overhead, taxes, refunds, and costs not entered as per-unit expenses.

Results are estimates and do not include taxes or unentered overhead.
Given:
Calculation:
Profit per unit = 52 − 21 − 5.20 − 4.80 = $21.00. Total profit = 21 × 180 = $3,780. Revenue = 52 × 180 = $9,360. Margin = 3,780 ÷ 9,360 × 100 = 40.38%.
Result: $3,780 total product profit
Interpretation: Each sale contributes $21 before fixed overhead, and 40.38% of product revenue remains after the entered variable costs.
No. This model focuses on per-unit economics. Deduct monthly overhead separately when you need full business net profit.
Convert the percentage fee into a dollar amount per unit using the selling price, then enter that amount as the selling fee.
Yes. A negative result means the entered per-unit costs exceed the selling price.
Use net completed units if you are measuring realized profit. For a gross sales forecast, estimate refund effects separately.
This page combines unit margin with sales volume to estimate total product profit, while a basic margin calculator may only express profit as a percentage of revenue.
