How the Profit Margin Calculator works

Margin measures profit as a share of the price you charged. Not a share of your costs. That distinction is where most trades lose money: a 50% markup is only a 33% margin.

Margin % = (price − cost) ÷ price × 100
  1. You invoice a job at £1,500. Materials, labour and overheads cost you £1,050.
  2. Profit = £1,500 − £1,050 = £450.
  3. Margin = £450 ÷ £1,500 × 100 = 30%.
  4. The same £450 profit on £1,050 of cost is a 43% markup. Always quote from the price, not the cost.

Include your overheads (van, insurance, tools, admin) before you call it profit. A 'gross margin' that ignores overheads flatters the number and hides a loss-making job.
