About this tool
Profit is the selling price minus the cost. Margin is that profit divided by the selling price and multiplied by 100, so it shows what share of each sale you keep as profit. The selling price must be above zero, and a price below cost gives a negative margin, meaning a loss.
Frequently asked questions
What is a good margin?
It depends on the business and its overheads. This tool reports the margin; whether it is enough depends on your other costs.
What does a negative margin mean?
A negative margin means the selling price is below cost, so each sale loses money.
