Work out net profit, profit margin and markup from your total cost and revenue. Free and instant.
Enter total cost and total revenue to see how much profit you make, your profit margin as a percentage, and the markup applied to cost.
A profit calculator shows how much money a sale or a whole business keeps after
costs. Enter your total revenue and total cost and it returns the net profit in
money, the profit margin as a percentage of revenue, and the markup on cost.
Use it to sanity-check pricing, compare products, or forecast the profit from a
deal. When cost climbs above revenue the result turns negative, flagging a loss
so you can adjust price or trim costs before you commit.

Frequently asked questions
What counts as cost here?
Use the total cost of the goods or service you are selling — the cost of goods sold. For net profit after overheads, include operating expenses in the cost figure.
How is profit margin different from profit?
Profit is the raw amount you keep; profit margin expresses that profit as a percentage of revenue, which makes it easy to compare across different sale sizes.
Can profit be negative?
Yes. If cost exceeds revenue you make a loss, shown here as a negative profit and a negative margin.
