What this tool does
Works backward from a target profit margin to the selling price you need to charge, using your product cost, other fees, and desired margin percentage.
How to use it
Enter your product cost, any other per-unit fees (shipping, packaging, payment processing), and the profit margin percentage you want to hit. Results update immediately; the margin must be between 0% and 99%, since a 100% margin would mean an infinite price.
Worked example
With the defaults of an 18 cost, 4.5 in other fees, and a 40% desired margin, total cost is 22.50. Selling price = 22.50 ÷ (1 − 0.40) = 37.50, giving a profit of 15.00 per unit — 40% of that 37.50 selling price.
Formula
Selling price = total cost ÷ (1 − margin ÷ 100), where total cost = product cost + other fees. This is the algebraic rearrangement of the margin formula (margin = profit ÷ selling price) solved for price instead of margin.
Why margin near 100% breaks the formula
As the target margin approaches 100%, the denominator (1 − margin/100) approaches zero, so the required selling price grows without bound — there's no finite price at which cost is 0% of revenue unless the product is free. That's why this tool caps the input below 100% rather than allowing it.
Limitations
This tells you the price needed for a target margin on the cost and fees you enter — it doesn't check whether that price is realistic for your market, competitive with similar products, or likely to hit your sales volume. Verify the resulting price against what customers will actually pay before using it.
Scope, sources and privacy
The margin-to-price relationship follows the standard definition of profit margin used in retail and e-commerce pricing. Calculations run locally in your browser; the values you enter are never uploaded.
Frequently Asked Questions
- How is this different from the profit calculator?
- The profit calculator starts with a selling price and finds your margin; this one starts with a target margin and finds the selling price.
- What margin should I pick?
- It depends on your industry and costs, but many retailers target 30-50% margins on physical products.
- Can margin be 100% or more?
- No — margin is always below 100% by definition, since it's profit as a share of the selling price itself.
