About Markup Calculator Online
This tool calculates the selling price required to achieve a target markup percentage on top of your cost, or works in reverse to compute the markup percentage from your cost and selling price. Markup is the difference between selling price and cost, expressed as a percentage of cost.
Markup is not the same as margin. A 50% markup on a $10 cost gives a $15 selling price (50% of $10 = $5 markup), but the gross margin on that sale is only 33% ($5 profit on $15 revenue). This tool helps avoid the easy confusion between the two.
Useful for retailers, wholesalers, restaurants, and service businesses when pricing inventory or proposals. Always confirm whether your supplier or industry uses markup or margin when comparing numbers.
How to use this tool
How to compute selling price from cost and markup
Enter the cost
"Cost" is what the item costs you to acquire or produce — supplier price plus inbound freight, but not your overhead. Use the same currency you'll charge in.
Enter the markup %
"Markup %" is the percent over cost you want to add (e.g. 50 turns $10 into $15). Markup ≠ margin: 50% markup is a 33.3% margin.
Press Run
Result returns sellingPrice = cost × (1 + markup% / 100), rounded to 2 decimals. Sales tax and other downstream fees are NOT added — pair with sales-tax-calculator-online if you need the consumer price.
Inverse: from price + margin
If you have a target margin instead of markup, use profit-margin-calculator-online (cost + price → margin). To go from price + margin → cost, solve `cost = price × (1 − margin%/100)` by hand.
