What the result means
Retail margin shows how much of the sale price remains after direct product and selling costs. A low margin leaves little room for returns, ads, overhead, and profit.
Margin = (Net Selling Price − Total Unit Cost) ÷ Net Selling Price × 100.
Benchmark: margin above 40% is excellent, 25% to 40% is good, 15% to 25% is average, and below 15% is weak.
Example calculation
If cost is $25, shipping is $4, price is $60, and fee is 5%, margin is calculated after marketplace fee and unit costs.
Tips for better results
- Do not confuse markup with margin.
- Include fees and shipping when pricing products.
- Compare target margin price against competitor price before changing price.
FAQ
What is a good retail margin percentage?
A strong retail margin is often above 40%, but acceptable margins vary by product category and sales model.
How do I calculate product margin?
Subtract unit cost and selling fees from selling price, then divide by selling price.
How much markup should I use in retail?
Markup should cover cost, fees, overhead, and desired profit while staying competitive.
What selling price gives a 40% margin?
The required selling price depends on product cost, shipping, fees, and the target margin.
How do fees affect retail margin?
Fees reduce net selling price, which lowers profit per unit and margin percentage.
