Frequently asked questions
What is a good profit margin for an online store?
There is no single perfect number, but most online stores aim for a 20 to 40 percent margin after all costs. Digital products can support higher margins, while competitive physical products may run lower. Use the calculator above to test different prices and find a margin that keeps your store sustainable.
How is profit margin calculated?
Profit margin is your profit divided by your selling price, shown as a percentage. First subtract the cost price and all fees from the selling price to get your profit. Then divide that profit by the selling price and multiply by 100. The calculator above does this math for you instantly.
Should I include shipping costs in my profit margin?
Yes. Any cost you pay on a sale, including shipping, packaging, and marketplace or payment fees, reduces your real profit. Add them all to the fees and shipping field above so the margin you see reflects what you actually keep.
