A selling price has to cover what the product costs you, pay you for your time, absorb selling fees and still leave a profit. The guides here turn that rule into formulas you can drop into Excel or Google Sheets.
Three common ways to set a price

| Cost-plus |
Total unit cost × (1 + markup) |
Simple products with stable costs |
Ignores what customers are willing to pay |
| Target margin |
Unit cost ÷ (1 − target margin) |

Selling fees must be counted in cost or margin |
| Market-based |
Start from comparable prices, then check your margin |

Can hide a loss if your costs are not checked |
The core formulas
- Margin % = (price − cost) ÷ price
- Markup % = (price − cost) ÷ cost
- Price for a target margin = cost ÷ (1 − margin)
- Markup from margin = margin ÷ (1 − margin)
Example: with a unit cost of $12 and a target margin of 40%, the price is $12 ÷ 0.6 = $20. The markup on that price is 66.7%, not 40%.
Percentage selling fees are charged on the sale price, so they come straight off your margin. If percentage fees add up to 10% of the price, a 40% margin before fees becomes 30% after them. Build the fees into your formula instead of hoping the margin will absorb them.
