A product costs 60. You add 40%. The selling price becomes 84. So the margin is 40%, right? Nope. It is 28.6%—and that difference can quietly wreck a pricing plan.

Markup and margin describe the same profit from different starting points. They sound interchangeable, which is exactly why the mistake survives in spreadsheets, quotes and team conversations.

The trap in one sentence

Markup measures profit against cost. Margin measures profit against the selling price. Because the selling price is higher than cost, the same profit becomes a smaller percentage when expressed as margin.

Unit cost$60.00
40% markup$24.00
Selling price$84.00
Actual margin28.57%

Put any cost and markup into the Markup vs Margin Calculator to see the selling price and resulting margin immediately.

Two formulas, two different bases

Markup(Profit ÷ Cost) × 100
Margin(Profit ÷ Selling price) × 100

The arithmetic is easy. The business consequence is not. If a target margin is entered as markup, every sale starts below plan before discounts, payment fees, returns or overhead appear.

What markup actually creates a 40% margin?

With a unit cost of 60, a 40% margin requires a selling price of 100. Profit is 40, and 40 divided by the selling price of 100 gives the target margin.

To achieve a 40% margin, you need a 66.67% markup.Margin target and markup rate move further apart as the target margin rises.

Once you know revenue and cost, the Profit Margin Calculator gives margin, gross profit, markup and cost ratio in one view.

Discounts expose the mistake fast

Return to the $84 selling price. A 10% discount reduces it to $75.60. With cost still at $60, profit falls to $15.60 and margin drops to 20.63%. A discount that looks modest has removed 35% of the original $24 profit.

Use the Percentage Calculator to test price changes, then recalculate margin from the discounted revenue. This is especially useful when promotions are planned by one team and margin is owned by another.

A pricing workflow that avoids the trap

  1. Define the full unit cost on a consistent basis.
  2. Set the margin the business needs after direct cost.
  3. Convert that margin target into the required selling price.
  4. Stress-test planned discounts and transaction fees.
  5. Label every spreadsheet percentage as markup or margin.
