How to use it

  1. Enter your product cost in USD.
  2. Enter the selling price in USD.
  3. Click the Calculate button.
  4. Read the profit amount and margin percentage displayed.

What it does – The Cost Sell Margin Calculator takes the cost you pay for a product and the price you plan to charge, then instantly shows two numbers: the dollar profit you’ll earn and the margin expressed as a percentage of the selling price.

Why it matters – Profit tells you the cash left after covering cost, while margin lets you compare profitability across items that have different price points. A higher margin means more of each sale contributes to overhead and growth.

How to read the results – The profit line is the raw difference between sell price and cost. The margin line shows that profit divided by the sell price, expressed as a percent, so you can see what share of each sale is pure gain.

Pro tips

  • Add a small waste allowance to cost before calculating to protect against defects
  • Round profit to two decimals for accounting consistency
  • Enter sell price first if you’re pricing up from cost to avoid transposition errors
  • Double‑check that both numbers are in the same currency

Real-life examples
