Markup Percent Calculator: Formula & Examples

This calculator works out the markup percentage you add to a product’s cost to set its selling price. You enter the cost and either the selling price or the desired markup percent, and it returns the missing value plus the gross profit and margin. The standard formula is: Markup % = (Selling Price – Cost) ÷ Cost × 100.

Formula

Markup percent is the amount added to the cost of a product, expressed as a percentage of that cost. In symbols:

Markup % = (Selling Price − Cost) ÷ Cost × 100

• Selling Price – the price you charge customers (in dollars, euros, etc.)
• Cost – what you pay to acquire or produce the item (same currency)
• Markup % – the percentage increase over cost

Related formulas you will often see in the same context:

• Selling Price = Cost × (1 + Markup %/100)
• Gross Profit = Selling Price − Cost
• Gross Margin % = (Selling Price − Cost) ÷ Selling Price × 100 (note the different denominator)

Worked Example

Using the default values from the calculator: cost = $50, selling price = $75.

1. Subtract cost from selling price: $75 − $50 = $25 (this is the gross profit).
2. Divide the profit by the cost: $25 ÷ $50 = 0.5.
3. Multiply by 100 to get a percentage: 0.5 × 100 = 50%.

So the markup percent is 50%, the gross profit is $25, and the gross margin is 25/75 × 100 = 33.33%. The calculator shows the same values: markup 50%, profit $25, margin 33.33%.

Markup vs. Margin: Why the Difference Matters

A very common mistake is confusing markup percent with gross margin percent. They are related but not the same. Markup is a percentage of the cost; margin is a percentage of the selling price. For example, a 50% markup on a $50 cost gives a $25 profit, but that profit is only 33.33% of the $75 selling price. Conversely, a 50% margin means the profit is half the selling price, which requires a 100% markup on cost. Retailers often talk in terms of margin because it directly shows how much of each sales dollar is profit, while suppliers and wholesalers often quote markup because it is simpler to apply to cost. Always know which one you are using when comparing prices or setting your own.

How to Choose a Markup Percent

There is no single “correct” markup. It depends on your industry, operating costs, and competition. A common starting point for many retail products is a 50% markup (often called “keystone pricing”), but this varies widely:

• Groceries and commodities – often 10–20% because volumes are high and competition is fierce.
• Clothing and accessories – frequently 50–100% to cover seasonal markdowns and inventory risk.
• Electronics and appliances – often 20–40% because customers compare prices easily.
• Specialty or handmade items – may use 100% or more to account for labor and low volume.

To choose your own, start by calculating your total cost (purchase price plus shipping, packaging, and any other direct costs). Then decide on a target gross margin that covers your overhead (rent, salaries, utilities) and leaves a profit. Use the formula in reverse: Selling Price = Cost ÷ (1 − Margin%). For example, if you want a 40% margin and your cost is $30, the selling price should be $30 ÷ (1 − 0.40) = $50.

Common Mistakes and How to Avoid Them

• Using the wrong base – markup is based on cost, margin on price. Mixing them up can seriously misprice items.
• Forgetting all costs – if you only include the wholesale price but ignore shipping and fees, your markup will be too low to cover expenses.
• Rounding too early – rounding the markup to a whole number before calculating the selling price can shift the final price by several cents or more. Do the math with full precision, then round the final price.
• Ignoring discounting – if you plan to offer sales, your regular markup needs to be high enough so that the discounted price still yields a profit.

Limits of the Simple Markup Formula

The basic markup formula assumes a single product and a simple cost structure. It does not account for quantity discounts, tiered pricing, or variable costs that change with volume. It also does not factor in the time value of money, opportunity costs, or the fact that some products may be loss leaders. For a business with many products, a more detailed costing model that includes overhead allocation is necessary. The formula is a starting point, not a complete pricing strategy.

Frequently Asked Questions

How do I calculate markup percent from cost and selling price?

Subtract the cost from the selling price to get the profit, then divide that profit by the cost and multiply by 100. For example, if an item costs $20 and sells for $30, the markup is (30−20)/20 × 100 = 50%.

What is a good markup percentage for retail?

There is no universal number. Many retailers aim for 50% markup (keystone), but it depends on your industry and overhead. A good markup is one that covers all your costs and leaves a profit while staying competitive. Calculate your break-even markup first, then add your desired profit margin.

What is the difference between markup and margin?

Markup is the percentage of the cost that you add to get the selling price. Margin is the percentage of the selling price that is profit. For example, a 50% markup on a $50 cost gives a $75 price and a $25 profit, which is a 33.33% margin. They are different numbers because they use different bases.

How do I find the selling price if I know the cost and the markup percent?

Multiply the cost by (1 + markup percent/100). For a $40 cost and a 25% markup, the selling price is $40 × 1.25 = $50. This is the reverse of the markup formula.

Can markup percent be more than 100%?

Yes. A 100% markup means the selling price is double the cost (profit equals cost). Markups above 100% are common for items with high perceived value or low sales volume, such as jewelry or artwork. There is no mathematical upper limit, but market demand will limit what customers will pay.

Does markup percent include taxes?

No. The standard markup formula uses the cost of the product and the selling price before sales tax. Sales tax is added on top of the selling price at the point of sale and is not part of the markup calculation. If you are calculating profit, taxes are an expense that should be considered separately.
