How to Calculate Margin and Markup Online Free

To calculate profit margin, enter your cost and selling price into the Margin & Markup Calculator and it instantly returns profit, margin (profit as a percentage of price) and markup (profit as a percentage of cost). To find the price for a target margin, switch modes and enter the cost and the margin you want. Everything runs in your browser, so your costs and prices are never uploaded.

What the calculator does

Pricing has three numbers that get tangled together: profit, margin, and markup. This tool untangles them. Give it a cost and a price and it shows all three at once, with margin and markup displayed side by side so you never confuse the two. It also works in reverse — tell it the cost and the margin you are targeting, and it returns the exact selling price you should charge. It is built for retailers, freelancers, resellers, and anyone quoting a job.

Step by step: from cost and price to margin

1. Select your currency so the results display in the symbol you work in.
2. Choose the "cost & selling price" mode. This is the standard direction when you already know both numbers.
3. Enter the cost price of the item — what it costs you to buy or make.
4. Enter the selling price you charge the customer.
5. Read the results: profit, profit margin, and markup appear together. For a $60 cost sold at $100, you will see $40 profit, a 40% margin, and a 66.7% markup.

Step by step: pricing for a target margin

When you know the margin you need but not the price, use reverse mode:

1. Switch to "cost & target margin" mode.
2. Enter the cost price.
3. Enter the target margin as a percentage — say 40%.
4. Read the required selling price. The tool divides the cost by (1 − margin ÷ 100); a $60 cost at a 40% target margin returns a $100 price.

Because a margin of 100% or more is mathematically impossible — it would mean zero or negative cost — the calculator caps the target below 100% and warns you if you enter too high a value.

Margin vs markup at a glance

Cost	Price	Profit	Margin	Markup
$60	$100	$40	40.0%	66.7%
$80	$100	$20	20.0%	25.0%
$50	$125	$75	60.0%	150.0%

Notice the margin is always the smaller number for the same profit, because it is measured against the larger figure (price) rather than the smaller one (cost). Mixing them up is the most common pricing error, which is why the tool shows both.

Why in-browser and private matters

All calculations happen locally in your browser with nothing sent to a server, so your margins, costs, and quoted prices stay confidential — useful when you are pricing against competitors or preparing a sensitive client quote. It also means the tool works offline once loaded, and there is no sign-up. Results are estimates to guide pricing decisions and are not financial advice.

FAQ

What is the difference between margin and markup?

Margin is profit as a percentage of the selling price; markup is profit as a percentage of the cost. The same $40 profit on a $60 cost sold at $100 is a 40% margin but a 66.7% markup, so always confirm which one a supplier or client means.

How do I find the price for a specific margin?

Use the reverse mode: enter the cost and the target margin, and the calculator returns the price by dividing cost by (1 − margin ÷ 100). It saves you from guessing a price and checking the margin repeatedly.

Why won't the calculator accept a 100% margin?

A 100% margin implies zero cost, and anything above it is impossible because profit cannot exceed the whole selling price. The tool caps the target below 100% and warns you, preventing a nonsensical price.

Is my pricing data kept private?

Yes. Every calculation runs in your browser and nothing is transmitted, so your costs, prices, and margins never leave your device.
