What is this tool for?

Profit margin is the share of the selling price that is profit. Markup is the profit as a share of the cost. They are often mixed up: a product bought for 100 and sold for 150 has a markup of 50% but a margin of 33.3%. Knowing both helps you price without losing money.

How to use it

Choose what you want to find: profit and margin, or a selling price from a target.
Enter the cost per unit and the selling price or target percentage.
Add other costs per unit, such as packing and delivery, and the units you expect to sell.
Add fixed costs such as rent to see how many units you must sell to cover them.
Read the result and copy it.

Tips

Include every cost, not only the purchase price: packing, delivery, payment fees and a share of rent and salaries. A product that looks profitable can lose money once all costs are counted.

Frequently asked questions

What is the formula for profit margin?

Margin % = (selling price − cost) ÷ selling price × 100.

What is the formula for markup?

Markup % = (selling price − cost) ÷ cost × 100.

How do I find the price for a 30% margin?

Divide the cost by 0.70. For a cost of 70, the price is 100.

The number of units you must sell so that the profit covers your fixed costs.
