The margin of a product within the product master data is calculated using markdown calculation. That's why it's also referred to as markdown margin or markdown spread. The calculation follows this formula:
Example: You purchase ballpoint pens for €0.30 net per piece and want to sell them for €0.99 gross. To calculate the margin, first determine the gross purchase price, which in our example is €0.357 per piece. Now enter the gross purchase price and gross selling price into the formula:
You get a margin of approximately 63.9%, rounded.
Please note that the backend always calculates using all decimal places, and rounding only occurs at the end of the calculation. So if you arrive at different values, this could be due to rounding differences.
