Markup Calculator

What Is a Markup Calculator?

A markup calculator turns cost into a selling price. You enter what a unit costs you and the markup percentage you want to add, and it returns the price you should charge, along with the gross margin that price produces. This tool runs three ways: cost plus markup to price, cost plus price back to markup, and the one most calculators leave out, the markup you need to hit a target margin.

Selling price = Cost × (1 + Markup % / 100)

A product that costs $40 with a 50% markup sells for $60. That $20 of profit is a 50% markup on the $40 cost, but only a 33% margin on the $60 price. Keeping those two numbers straight is the whole job, and it is where most pricing goes wrong.

Markup vs Margin

Markup and margin describe the same profit against different bases:

• Markup = profit ÷ cost
• Margin = profit ÷ price

Cost is always the smaller number, so markup is always the bigger percentage. This trips up more pricing decisions than any other single mistake. If a supplier or a spreadsheet tells you to "mark it up 40%," you do not get a 40% margin, you get about 29%. If you actually want a 40% margin, you have to mark up around 67%.

Markup on cost	Resulting gross margin
25%	20%
50%	33%
67%	40%
100%	50%
150%	60%

If you want to check any pairing the other direction, or solve from profit and price, use the margin calculator, which handles the full four-way relationship between cost, price, margin, and profit.

How to Set a Markup That Hits a Target Margin

Most pricing starts from the margin you need, not the markup you want. To convert a target margin into the markup that reaches it:

Required markup % = Margin % / (100 − Margin %) × 100

For a 40% target margin: 40 ÷ 60 = 0.667, so you need a 67% markup. For a 50% target margin you need a 100% markup. The calculator's third mode does this for you: enter your unit cost and the gross margin you want to end up with, and it returns the exact markup and the selling price.

This matters most when you price a whole catalog off a single rule. A flat "2x cost" rule (100% markup) gives you a 50% gross margin on every SKU, which is fine, as long as you know that is what it does and you have priced the downstream costs in.

Ecommerce Pricing Context

Markup sets the shelf price. It does not tell you whether the sale makes money, because the cost you mark up is usually just the product cost, and an ecommerce order carries several more costs after that:

• Shipping and fulfillment, often $5 to $9 per order.
• Payment processing, roughly 3% of the order.
• Discounts and promo codes, which come straight out of margin.
• Returns, the refund plus the cost to process it.
• Ad spend to acquire the customer in the first place.

A healthy-looking 100% markup and 50% gross margin can land at a 15% to 25% contribution margin once those are counted. That is not a reason to stop using markup, it is the fastest way to set a price, but it is the reason to check the price against contribution margin before you commit. Use the contribution margin calculator to see what a marked-up price actually leaves you per order.

Worked Example

A homewares brand sources a ceramic mug for $6.20 landed and wants a 60% gross margin.

Input	Value
Unit cost	$6.20
Target gross margin	60%
Required markup	150%
Selling price	$15.50
Profit per unit	$9.30

A 150% markup on a $6.20 cost sets the price at $15.50 and delivers the 60% gross margin the brand wanted. If instead they had "added 60%" as a markup, the price would have been just $9.92 and the margin only 37.5%, a $5.58 difference per unit that would have quietly capped the business well below its target. That is the markup-vs-margin gap doing damage, and it is exactly what this calculator is built to prevent.

From Markup to the Margin You Need

Markup is applied to cost to set a price; margin measures the profit that price leaves. A markup calculator is the fastest way to price from cost, and the target-margin mode bridges the two so you can price by markup while landing on the margin you actually need.
