How to verify the result
A useful tool should let you verify its output. Start with a small test, keep the original and only then use the result in production. The scenario below helps catch problems before you copy, download or share anything.
Practical check
Try a cost of 60 and sale price of 100: profit is 40; distinguish margin on sales from markup on cost.

Margin on cost vs. markup divisor
Many sellers make the mistake of adding the margin to the cost (e.g. Cost + 30%). That yields a smaller real profit than planned.
The correct formula is: Price = Cost / [1 - (Expenses % + Margin %)], so your net margin is exactly the planned percentage of the final price.
Worked example
Cost $50, expenses 15% and target margin 30%. Markup divisor = 1 - (0.15 + 0.30) = 0.55. Price = $50 / 0.55 = $90.91. Real net profit = $27.27 (exactly 30% of the price).
How to use
Enter the product cost, the expenses percentage (taxes, card fees and fixed costs) and your desired profit margin. The calculator applies the markup divisor and shows the ideal selling price, the markup multiplier and the net profit in currency — ready for you to price without selling at a loss.
Frequently asked questions
Difference between margin and markup?
Margin is profit as a % of the selling price; markup is the multiplier over cost. The tool shows both.
Should taxes go in expenses?
Yes. Add taxes, card fees and fixed costs into the expenses (%) field.
Why can't I use 100% margin?
Because expenses + margin must be under 100% for the markup divisor to exist.
