Systematic introduction of Difference between markup and margin calculations with step-by-step demonstrations
Sarah's big "aha!" moment was realizing she was pricing to cover costs, not for value. Part of that problem often comes from confusing two important business words: markup and margin. They both sound like they're about profit, but they measure it differently — and mixing them up can cost a business a lot of money.
Let's use a simple example. Sarah buys website hosting services for a client at $100 and charges the client $200 for the complete setup. Same $100 profit — but watch what happens when we describe it two different ways.
Sarah's hosting cost is fixed at $100. Drag the slider to change her selling price:
Selling Price: $200
Cost
$100
Profit
$100
Selling Price
$200
Markup — profit vs. cost
100.0%
$100 profit ÷ $100 cost × 100
The green bar grows faster than the gray bar — markup accelerates as price rises.
Margin — profit slice of revenue
50.0%
$100 profit ÷ $200 revenue × 100
The green slice = how much of every revenue dollar Sarah keeps.
Notice: markup always shows a larger percentage than margin for the same profit. At $200 price, markup is 100% but margin is only 50%. They describe the same profit in completely different ways — and confusing them can wreck a pricing strategy.
Before reading the formulas below, see how much you already understand from the charts. Complete these sentences — the answers are all in the visualizer above.
Confirm your answers above with the official formulas:
Markup Formula
Markup = (Selling Price − Cost) ÷ Cost × 100%
Profit as % of what you paid
Margin Formula
Margin = (Selling Price − Cost) ÷ Selling Price × 100%
Profit as % of what the customer pays
Businesses usually care more about margin because it shows how much of each sales dollar they keep as profit. Financial reports almost always use margin — not markup — because it gives investors and managers a clearer picture of efficiency.
Sarah's $5,000 Website Project
- • Cost to deliver: $2,000
- • Markup: 150% — sounds huge, might worry a client if they knew
- • Margin: 60% — tells Sarah she keeps 60¢ of every dollar earned
- When Sarah pitches investors, they will ask for her gross margin — not her markup. Investors think in margin.
