Markup Calculator Online
Calculate selling price, profit and equivalent margin from cost and a markup percentage, right in your browser. Estimates only, not financial advice.
The Markup Calculator runs entirely in your browser. The cost and markup figures you enter never leave your device and are not uploaded to ArrayKit. Results are estimates only, not financial or tax advice.
The Markup Calculator turns a product cost and a markup percentage into a selling price, a profit amount, and the equivalent gross margin percentage. Enter what you paid for an item and the percentage you want to add on top, and it instantly shows the price you should charge, how much profit that leaves, and how that markup translates into margin — a distinction that trips up a lot of retailers, since a 40% markup is only about a 28.6% margin, not 40%. It's useful for retailers pricing inventory, freelancers quoting cost-plus work, and small-business owners checking whether a price covers their target profit. These are estimates only, not financial or tax advice, and everything computes locally in your browser — your cost and pricing figures stay on your device.

Common errors & troubleshooting
Selling price looks too low for the markup entered. — Enter the markup as a whole percentage, e.g. 40 for 40%, not 0.4 — the Markup Calculator multiplies by markup% / 100 internally.
Expected the margin to match the markup percentage. — Markup is a percentage of cost while margin is a percentage of selling price, so they are never equal above 0% — a 40% markup always works out to a lower margin percentage.
Result shows a banner instead of a price. — Check that cost is 0 or more and markup percentage is -100 or more; a markup below -100% would imply a negative selling price.
Need margin as the starting point instead of markup. — Use the Margin Calculator below if you know the target margin percentage and want to work backward to the markup and price.
Frequently asked questions
What does the Markup Calculator compute?
It computes selling price, profit and equivalent margin percentage from a cost and a markup percentage: selling price = cost × (1 + markup% / 100), profit = selling price − cost, and margin% = profit ÷ selling price × 100.
What is the difference between markup and margin?
Markup is profit as a percentage of cost; margin is profit as a percentage of selling price. The Markup Calculator shows both so a 40% markup on a $50 cost is clearly a 28.6% margin, not 40%.
Can I enter a negative markup percentage?
Yes, down to -100%. A negative markup models a discount off cost and produces a selling price below cost, useful for checking a clearance price against your break-even point.
Does the Markup Calculator work in any currency?
Yes. Cost and selling price are plain numbers, so enter figures in dollars, euros, rupees or any currency and read the results in the same unit.
Is the Markup Calculator financial advice?
No. It gives fast pricing estimates only, not financial or tax advice. Verify pricing and profit decisions with a qualified professional before finalizing them.
Does the Markup Calculator upload my cost and pricing figures?
No. The Markup Calculator runs entirely in your browser. The numbers you type never leave your device and are not uploaded to ArrayKit.
