Calculate gross profit, net margin percentage, and markup from cost and revenue.
Calculate final sale price and total money saved with single or stacked discounts.
Calculate X% of Y, percentage increase/decrease, percentage difference, and ratio.
This markup calculator converts between markup percentage and profit margin percentage, two related but frequently confused pricing metrics that use different base numbers. It's designed for retailers, wholesalers, and small business owners setting prices who need to translate a target markup into an equivalent margin (or vice versa) without making a costly pricing mistake. Enter either a markup percentage or a margin percentage along with your cost, and the calculator instantly shows the corresponding value for the other metric along with the resulting selling price. Because markup is calculated on cost while margin is calculated on selling price, the two numbers are never equal for the same product, and mixing them up is a common and expensive error in pricing strategy. The tool is completely free, requires no signup, and every calculation happens locally in your browser, so your pricing data is never uploaded or stored anywhere. Scroll down to enter your numbers and convert between markup and margin instantly.
Markup is profit expressed as a percentage of cost, while margin is profit expressed as a percentage of the selling price — the same dollar profit produces two different percentages depending on which base you use.
Margin = Markup / (1 + Markup), when markup is expressed as a decimal. This calculator performs that conversion instantly.
Markup = Margin / (1 − Margin), when margin is expressed as a decimal. Enter your margin and the calculator returns the equivalent markup.
No, a 50% markup on cost equals a 33.3% margin on selling price — they are only equal at 0%, which is why converting correctly matters for pricing.
Both are expressed as percentages of profit, but because they use different denominators (cost vs. revenue), using them interchangeably can lead to underpricing products.
Selling Price = Cost / (1 − Margin), where margin is a decimal. This calculator computes that automatically once you enter cost and target margin.
