How markup and margin work

Markup and margin describe the same dollars from two directions. Markup is your profit as a percentage of what the item cost you, while gross margin is that same profit as a percentage of the price the customer pays. Because the price is always larger than the cost, the margin is always the smaller number, and the gap widens as the markup goes up.

Mixing the two up is expensive. A contractor who wants a 40% gross margin and marks everything up 40% ends up with a 28.6% margin, which is more than 11 points short on every job.

The two formulas

Markup % = profit ÷ cost × 100
Gross margin % = profit ÷ selling price × 100

Profit is the selling price minus your cost in both formulas, and the only thing that changes is what you divide it by.

  • Small parts usually carry higher markups than equipment and fixtures, because the dollars per item are small and the cost of stocking and handling them is proportionally high.
  • Plumbing contractors commonly mark up fixtures 30% to 60% and small parts 75% to 150% or more.
  • HVAC contractors commonly mark up equipment 25% to 50% and parts 50% to 100% or more.
  • The margin shown here covers materials only, so labor, overhead, and profit on the whole job still need their own math.

For typical ranges and how to set your own numbers, see our guides to plumbing material markup and HVAC material markup. To find what an hour of field labor costs you, use the Labor Burden Calculator.
