- Under Cost price (net), enter what the product costs you to source. Both comma and period work as decimal separators.
- Under Selling price (net), enter the price at which you offer the product.
- Done: the calculator updates the three result tiles instantly with every input – no button or sign-up needed.
You can change the values as often as you like and play through different price scenarios in seconds, such as a planned price increase or new terms from your supplier.
How to read the three result values
Profit per unit shows the absolute amount in euros you keep per product sold. The margin expresses this profit as a percentage and makes products with different prices directly comparable. The markup is the second percentage and always sits above the margin – don’t let that confuse you; both values describe the same profit.
Important is the red warning: it appears as soon as your selling price is below the cost price and explicitly tells you that you make a loss on every sale. In that case you should review your price or sourcing immediately.
Practical tips for your pricing
Don’t calculate your prices once, but recalculate them regularly: suppliers often raise cost prices quietly, and what was profitable a year ago can be a loss-maker today. A fixed appointment each quarter where you run your most important products through here protects you from creeping margin erosion.
Also think in scenarios rather than single values: test in the calculator how small price adjustments – say from €49.99 to €54.99 – affect profit per unit. And if you sell with paid advertising, check with our ROAS calculator whether your campaigns are eating up the margin you calculated.

Frequently asked questions
- How do I calculate the margin from selling price and cost price?
- Subtract the cost price from the selling price and divide the result by the selling price. Multiplied by 100 you get the margin as a percentage. The calculator above does this automatically and additionally shows you profit and markup.
- What is the difference between margin and markup?
- Both values use the same profit but relate it to a different base: the markup refers to the cost price, the margin to the selling price. That is why the markup percentage is always higher than the margin, even though the absolute profit is identical.
- What is a good margin for an online store?
- It depends on the industry: fashion often sits at 50 to 70 percent, electronics more at 10 to 25 percent. What matters is that profit remains after deducting shipping, fees, advertising, and returns. So always calculate with your complete costs, not just the cost price.
- Should I calculate the margin with net or gross prices?
- Always calculate with net prices, i.e. without sales tax. Sales tax is a pass-through item and not part of your profit. The calculator above therefore also works with net values – simply enter cost price and selling price without tax.
- How much discount can I give without making a loss?
- Your maximum discount equals your margin: if the margin is 40 percent, the discount may at most be just below that, otherwise you sell below cost price. Note that fees and shipping squeeze the margin further. Use the calculator above to check how much headroom remains before every promotion.
