What is a markup calculator?

A markup calculator helps you set the right selling price for a product by adding a chosen markup percentage on top of what the item costs you. It is one of the most useful pricing tools for online sellers, retailers, wholesalers and any small business that buys products and resells them at a profit. Enter your cost and desired markup, and the calculator instantly shows your selling price, your profit per unit, and the resulting profit margin.

Correct pricing is the difference between a business that grows and one that quietly loses money. Set your markup too low and you will not cover overhead; set it too high and you may price yourself out of the market. This tool lets you experiment with different markups in seconds so you can find the sweet spot.

How the markup calculator works

You provide two numbers: the product cost and the markup percentage. The calculator multiplies the cost by the markup to find your profit, adds it to the cost to find your selling price, and then converts that profit into a margin percentage so you can compare it directly with your target margin.

Markup formula

  • Selling Price = Cost + (Cost × Markup %)
  • Profit = Cost × Markup %

Example calculation

Say a product costs you $50 and you apply a 40% markup. Your profit is $50 × 40% = $20, so your selling price becomes $50 + $20 = $70. That $20 profit on a $70 sale works out to a profit margin of about 28.6%.

The difference between markup and profit margin

This is one of the most common sources of confusion in small business pricing. Markup is your profit measured against your cost, while marginis your profit measured against your selling price. Because the denominators differ, the two percentages are never the same for the same sale.

  • A 25% markup equals a 20% margin.
  • A 50% markup equals a 33% margin.
  • A 100% markup equals a 50% margin.

Understanding this relationship prevents you from accidentally underpricing. When someone says they want a "50% margin," applying a 50% markup will leave you short — you would actually need a 100% markup. Use this calculator alongside our profit margin calculator to keep both numbers in view.

Methodology & Accuracy
