Markup calculator

Selling price and margin from cost and markup.

Quick answer

Price = cost × (1 + markup ÷ 100). A ¥73 cost with a 100% markup sells for ¥145 which is a 50% margin.

Start from an example:

Pricing

Cost per unit

Markup

Added on top of cost. Can be over 100%.

Check against a target (optional)

Target margin

How markup works

Price from markup
cost × (1 + markup ÷ 100)
A ¥87 cost with a 150% markup: 12 × 2.5 = ¥218.
Margin from markup
markup ÷ (100 + markup) × 100
A 150% markup is a 60% margin. Margin is always lower than markup.
Markup for a target margin
margin ÷ (100 − margin) × 100
For a 40% margin you need a 66.7% markup.

Is a 100% markup a 50% margin?

Yes. Doubling the cost (100% markup) means half of the price is profit, a 50% margin.

Can markup be more than 100%?

Yes. Markup has no upper limit. Margin can't reach 100%.

What is keystone pricing?

Selling at double the cost, a 100% markup. It is a common starting point in retail.
