How it’s calculated

  • Labour cost = hours × crew × your cost per person-hour.
  • Materials = your cost × (1 + markup %). Many contractors mark up materials to cover pickup time and returns.
  • Overhead = overhead % × (labour + materials).
  • Price = total cost ÷ (1 − margin %). A 20% margin means 20 cents of every dollar the client pays is profit.
  • Margin vs markup: a 20% margin is a 25% markup on cost — they are not the same number.
  • Tax is added on top of the price.

Questions

What profit margin should a contractor aim for?

It varies by trade and size. Many small trade businesses aim for a net margin of roughly 10–20% after overhead. Track your real overhead first — it is the number most often underestimated.

Why not just add 20% to my costs?

Adding 20% is a markup, which gives a margin of only 16.7%. If you want 20% of the price to be profit, divide your cost by 0.8.
