Profit margin calculator
What counts as healthy depends entirely on the trade — grocery lives at 3%, software at 80%.
Profit margin is profit divided by selling price. A product costing 50 and selling at 100 has a 50% margin and a 100% markup — the same 50 of profit, divided by two different numbers. To hit a target margin, divide cost by one minus that margin.
How to calculate profit margin
This page calculates gross margin — revenue minus the direct cost of goods. It is deliberately not net margin, which subtracts everything else: rent, wages, marketing, payment fees, returns and tax. A retailer running a 45% gross margin can easily end up at 4% net, and it is the net figure that determines whether the business survives. Gross margin is still the right number for a pricing decision on one product, because it is the only part of the chain that product controls.
