Price with Fees & Taxes

Q: How do I calculate a selling price with fees?

Add your fixed costs, then divide that total by one minus the percentage costs and target net margin expressed as decimals. This calculator does that automatically.

Q: Should sales tax count as a cost?

Sales tax does not reduce your listed-price margin when it is added at checkout and passed through to the tax authority. Include it as a cost when you absorb it or it is withheld from your listed price.

Q: What is net profit margin?

Net profit margin is the share of your selling price left after fixed costs, fees, taxes, and other costs deducted from the price.

Q: Why can no selling price work?

A price cannot cover the calculation when percentage costs deducted from the price plus the target net margin equal or exceed 100 percent.

Use this pricing calculator to find the selling price that still leaves the profit you want after shipping, taxes and platform fees. Everything updates as you type.

How to calculate a price with fees and taxes

This pricing calculator, sometimes called a pricing simulator or selling price calculator, starts with every fixed cost you pay per unit, such as product cost, packaging, shipping, materials, or labor. Then add the percentage costs that come out of the listed price, including marketplace and payment-processing fees. Finally, choose the net profit margin you want to keep.

Selling on Amazon? Try the Amazon FBA Fee Calculator, which starts from Amazon referral and fulfillment fees. Selling on Etsy? Use the Etsy Fee Calculator, which starts from Etsy listing, transaction and processing fees. Selling on eBay? Use the eBay Fee Calculator.

The calculator finds the listed price that covers those costs while preserving your target margin. Taxes added on top at checkout are shown separately because the customer pays them in addition to the listed price.
