Frequently Asked Questions
Common questions about the free online profit margin calculator.
Enter revenue, cost and fees. The margin is the gross profit divided by revenue, shown as a
percentage beside the profit figures.
Margin compares profit with the selling price, while markup compares the same profit with the
cost of the goods.
Net profit subtracts both the cost of goods and every fee you entered from the revenue, so it
is the money you actually keep.
It is the revenue needed to cover your fees at the current cost ratio, so any sale above that
level produces a net profit.
The two use different bases. A fifty percent markup is only a thirty three percent margin,
because the selling price is larger than the cost.
Yes. If the cost and fees are larger than the revenue the net profit turns negative and the
tool warns you that the sale is below break even.
