The Markup Calculator finds the markup percent, the amount added on top of cost to reach a selling price, expressed as a percentage of that original cost. Enter the cost and the selling price, and the calculator returns the markup percent alongside the equivalent profit margin percent, since the two figures answer related but distinctly different questions from the same two numbers.
Markup and margin are often confused because they are calculated from the exact same inputs, cost and price, but they use different numbers as the base for the percentage. Markup measures against cost; margin measures against price. Getting that distinction right matters for pricing decisions, since the two percentages are never equal except at 0%.

Understand the markup formula
Markup percent is calculated as Markup % = (Price - Cost) / Cost x 100. This expresses the dollar profit as a percentage of what the item cost to acquire or produce, answering the question "how much more than cost was charged."
Take an item that costs $100 and sells for $150. The dollar profit is $150 minus $100, or $50. Dividing that $50 profit by the $100 cost gives a markup of 50%, meaning the selling price is 50% more than what the item cost. The Markup Calculator computes this directly from the cost and price entered.
See how markup differs from margin on the same numbers
Margin percent, calculated from the same two figures, is Margin % = (Price - Cost) / Price x 100, dividing the same $50 profit by the $150 selling price instead of the $100 cost.
That gives a margin of approximately 33.33%, a noticeably different number from the 50% markup calculated above, even though both describe the exact same $100-cost, $150-price transaction.
This gap between markup and margin grows larger as the profit percentage itself grows larger, and it is a common source of pricing errors: setting a price by targeting a markup percentage that was actually intended as a margin target (or vice versa) produces a meaningfully different, and often disappointing, actual result. The Markup Calculator shows both figures together specifically to prevent that confusion.
Set a selling price from a target markup
Because markup is calculated against cost, solving for a selling price given a target markup percent is straightforward: Price = Cost x (1 + Markup % / 100). A retailer wanting a 50% markup on a $100 cost item would set a price of $100 x 1.50, or exactly $150, matching the worked example above.
This forward calculation is often how markup is actually used in practice: cost is known, a target markup percent is set by policy, and the resulting price follows directly.
Understand why markup and margin serve different purposes
Markup is often used at the point of pricing, since it directly answers "how much to add on top of cost," a natural way to think about pricing from a cost basis.
Margin is often used when analyzing profitability after the fact, since it answers "what percentage of each sales dollar is actual profit," which ties more directly to revenue and profitability reporting.
Knowing which one a colleague, a spreadsheet, or an industry benchmark is actually referencing before comparing numbers is essential, since a "40% markup" business and a "40% margin" business have very different actual profit percentages relative to their prices, even though both use the word "40%."
Know the limits of this calculation
This calculation covers cost and selling price only; it does not account for additional expenses such as shipping, payment processing fees, returns, or overhead that might reduce the actual profit realized beyond the simple cost-versus-price comparison shown here. A markup calculated purely from product cost may overstate true profitability once those additional costs are factored in.
Use the Markup Calculator to set pricing policy from a cost basis and to understand the relationship between markup and margin on any given transaction. For a full profitability picture, account for additional operating costs separately.
Frequently asked questions
What is the formula for markup percent?
The formula for markup percent is (Price - Cost) / Cost x 100. This measures the profit as a percentage of the item's cost, distinct from margin, which measures profit as a percentage of the selling price instead.
What is the markup on an item that costs $100 and sells for $150?
An item that costs $100 and sells for $150 has a markup of 50%, since the $50 profit is 50% of the $100 cost.
How is markup different from margin?
Markup divides profit by cost, while margin divides the same profit by selling price. On a $100 cost, $150 price item, markup is 50% while margin is approximately 33.33%, even though both describe the same transaction.
How do I find a selling price from a target markup percent?
To find a selling price from a target markup percent, use Price = Cost x (1 + Markup % / 100). A 50% markup target on a $100 cost item gives a price of $100 x 1.50, or $150.
Why do businesses sometimes confuse markup and margin?
Businesses sometimes confuse markup and margin because both are calculated from the same two numbers, cost and price, and both are commonly expressed as percentages, but they use different bases for that percentage, cost for markup and price for margin, which produces different numeric results from the same transaction.
Summary
The Markup Calculator finds the percentage added on top of cost to reach a selling price using Markup % = (Price - Cost) / Cost x 100, while also showing the equivalent margin percentage calculated against price instead.
A $100 cost item selling for $150 has a 50% markup but only a 33.33% margin, illustrating why the two terms should never be used interchangeably despite describing the same transaction.
