Overhead and profit — markup vs. margin

Markup and margin are not the same percentage, and the difference is where new contractors quietly go broke. Set the margin first, then back into the markup.

Your direct cost isn't your price

On top of direct cost you have to add two things:

Overhead is the cost of being in business. Your truck, insurance, phone, software, and the hours you spend estimating jobs you don't win.

Profit is your reward for taking the risk.

You add both by applying a markup. Your markup has to cover overhead and profit. If it only covers profit, your profit is quietly paying your phone bill.

The concept most contractors get wrong

Markup and margin are not the same percentage. Same dollars, different denominators.

Take a job that costs you $1,000 and sells for $1,500. The profit is $500.

FormulaThis job
Markupprofit ÷ cost$500 ÷ $1,000 = 50%
Marginprofit ÷ price$500 ÷ $1,500 = 33%

A 50% markup is only a 33% margin. They describe the same dollars from different sides.

Decide the margin first

Pick the margin your business needs, then back into the markup that produces it.

If you want this margin……mark up your cost by
10%≈ 11%
20%25%
33%50%
50%100%

The formula behind the table: markup = margin ÷ (1 − margin). Put it in your estimating spreadsheet once and you never have to think about it again.
