Set retail prices from cost with the margin you need
Suppliers quote cost, shops think in markup, and accounts report margin. The calculator shows all three at once, so a price set on markup never surprises you at month end.
How retail teams use Profit Margin Calculator
- Enter the supplier cost and either the markup you use or the margin you need.
- Read the shelf price, profit per unit, margin and markup together.
- Before a sale, enter the discount % to see the margin after the discount and the extra units you must sell.
A 30% markup on cost is only a 23.08% margin; the calculator makes that gap visible before you print price tags.
Worked example: an item that costs 60 and sells for 100, with a 10% marketplace fee, a 0.30 fixed fee and 5 shipping
