Enter your cost and selling price — results update as you type.
Profit per sale
—
Contribution profit: what remains after variable costs, before fixed monthly overhead and taxes.
Contribution margin
—
Share of effective revenue left after variable costs. This is not net profit.
Original selling price
—
Effective revenue after discounts and returns
—
Revenue reduced by discounts and returns
—
Processing fees
—
Charged on revenue you actually collect, not the list price.
Total variable costs
—
Cost, shipping and packaging, processing fees and other variable fees combined.
Contribution margin is not net profit. Fixed monthly overhead — rent, software, salaries — and taxes still come out of the profit shown here. Treat the reading above as a prompt to investigate further, not universal financial advice.
