How to use the markup calculator

This guide explains the inputs, formula, assumptions, example calculation, and the difference between markup and margin.

What this calculator does

It calculates selling price and markup amount from cost and markup percentage. It also shows gross margin so you can compare the two terms.

Who should use it

Sellers, shop owners, and small business operators who need a quick pricing rule for products or menu items.

Input definitions

  • Cost: what it costs you to make or buy the item
  • Markup percentage: the extra amount you add on top of cost

Formula

  • Markup amount: cost × markup percentage
  • Selling price: cost + markup amount
  • Gross margin: markup amount ÷ selling price

Assumptions

  • Cost and markup apply to the same item or product line
  • The example uses USD, but the math works for any currency
  • Taxes, shipping, discounts, and fees are excluded unless you build them into cost

Quick example

A bakery item costs $30 and uses a 40% markup.

Markup amount = 30 × 40% = $12

Selling price = 30 + 12 = $42

Gross margin = 12 ÷ 42 = 28.6%

How to interpret the result

If you want a 40% markup, you are adding 40% of cost. That is not the same as a 40% gross margin.

Common mistakes

  • Using selling price instead of cost as the base
  • Confusing markup with margin
  • Ignoring overhead or fees that should be part of cost
