Example: How to calculate a 20% profit margin

Say, you add umbrellas to your webshop’s offering. The umbrellas cost you £10 a piece until they’re ready to ship to your customers. How much should you charge for an umbrella to reach a 20% profit margin? Hint: it’s not £12:

To sell at a 20% profit margin, you need to work out the markup you need to add over your expenses. Here’s a simple formula to reverse-engineer your asking price based on a desired profit margin.

Target price = Cost of goods / [1 - (Target margin / 100)]

So in the case of the umbrellas it looks something like this: 10 / [1 - (20 / 100)] or 10 / 0.8, which gives us an asking price of £12.5. So you need to sell your umbrellas with a 25%, or £2.5 markup to reach a 20% profit margin.

Gross profit margin vs. net profit margin

The key difference between gross profit margin and net profit margin is the costs included in the calculation.

The gross profit margin formula includes deducted costs associated only with production (manufacturing costs including packaging and parts), whereas the net profit margin also accounts for operating expenses as well as debt, taxes, and any other overhead costs.

  • Profit margin is a percentage – it’s an important indicator of profitability, also often expressed as ‘cents on a dollar’

Profit margin vs markup – What's the difference?

When considering return on equity calculations, knowing the difference between profit margin and markup will help you get your head around ROE with relative ease.

Both profit margin and markup use revenue and costs as a core aspect of their calculations.

The key difference between profit margin and markup is that profit margin refers to sales minus the cost of goods you sell while markup quantifies the amount by which the cost of a good is increased to reach the final selling price.

Think of them as metrics for the same thing, but used at different points in time: you use markup to set a target profit you want to generate by selling a product or a service, and profit margin to measure the success after you actually make the sale.
