How to Use

  1. Choose which calculation you need from the options above the form.
  2. Enter the cost, and either a markup percentage or a selling price — no need to type a % or $ sign.
  3. The result updates instantly, showing profit and the corresponding profit margin alongside the markup.
  4. Use Copy Result to copy the answer to your clipboard.

Formula

Selling price from cost + markup
selling_price = cost × (1 + markup% ÷ 100)
Markup % from cost + price
markup% = (selling_price − cost) ÷ cost × 100

Worked Example

A $100 cost with a 30% markup.

  1. Convert 30% to a decimal and add 1: 1 + 0.30 = 1.30
  2. Multiply by the cost: $100 × 1.30 = $130.00 selling price
  3. Profit: $130.00 − $100.00 = $30.00
  4. For comparison, that $30 profit is a 23.08% margin (profit ÷ selling price), not 30% — margin and markup are never the same number.

Result: Selling price: $130.00 (profit $30.00, margin 23.08%)

About This Tool

What this tool does

This calculator finds a selling price and profit from a cost and a markup percentage (or the reverse — a markup percentage from a cost and a selling price), and shows the corresponding profit margin alongside every result.

When to use it

Use it for cost-plus pricing (marking a product up by a fixed percentage over cost), or to check what markup a given selling price actually represents.

What the result means

Markup is profit expressed as a percentage of cost. Margin is profit expressed as a percentage of selling price — a genuinely different number for the same sale, always shown alongside the markup result here so the two are never confused. See the Profit Margin Calculator for the tool built the other way around, starting from a margin target instead of a markup.

Assumptions & limitations

Cost and selling price must be zero or greater. A markup below -100% is rejected (it would imply a negative selling price). Markup from a $0 cost is undefined (any positive price is an infinite markup over nothing), so that combination is rejected rather than guessed.

Frequently Asked Questions

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. A 30% markup on a $100 cost gives a $130 price and a $30 profit — but that $30 profit is only a 23.08% margin, not 30%, because margin divides by the larger selling price instead of the smaller cost.
How do I calculate a 30% markup?
Multiply the cost by 1.30 (1 plus the markup as a decimal). A $100 cost at a 30% markup sells for $130.
Should I price using markup or margin?
Either is valid — they're just different ways to express the same underlying profit. If you know the profit percentage you want relative to what a customer pays, use the Profit Margin Calculator instead; if you think in terms of a percentage over your cost, this tool is the more direct fit.
