Markup vs Margin: The Denominator Changes the Price

Understand why markup is measured against cost while margin is measured against selling price, and reconcile both directions.

Calculate both measures from the same amounts

markup = (price - cost) / cost

price
Selling price on the selected basis (currency per unit) โ€” user input
cost
Cost at the selected layer (currency per unit) โ€” user input

margin = (price - cost) / price

price
Selling price on the selected basis (currency per unit) โ€” user input
cost
Cost at the selected layer (currency per unit) โ€” user input

markup = margin / (1 - margin); margin = markup / (1 + markup)

markup
Gross profit divided by cost (ratio) โ€” calculated
margin
Gross profit divided by selling price (ratio) โ€” calculated

Worked example: one profit amount, two percentages

Use a two-way checkpoint

  • Price and cost use the same unit and indirect-tax basis. (not complete)
  • Gross profit equals price minus the selected cost. (not complete)
  • Margin recalculates against price. (not complete)
  • Markup recalculates against cost. (not complete)
  • The result is passed to volume and break-even checks rather than treated as proof of viability. (not complete)
