Keep in mind

What it leaves out

  • Industry normsA good margin in retail is a poor one in software. Compare with your sector.
  • TimingAccounting profit and cash in the bank aren't the same thing.
  • One-offsUnusual costs or gains in the period distort the margin.

Use the calculator to compare scenarios rather than as a guaranteed forecast.

About the Profit Margin Calculator

See what share of a business's sales remains after direct costs, operating expenses and other costs. The calculator gives gross, operating and net figures so a founder can identify which layer of spending has the largest effect on profitability.

How it works and an example to tryShow less

How to use the result

Subtract cost of goods sold from revenue for gross profit, then operating expenses for operating profit and other costs and taxes for net profit. Each margin is the relevant profit divided by revenue. Inputs must cover the same accounting period; the tool does not reconcile cash flow or define which items your accounts classify as operating costs.

Example to try

Model a coffee shop with 240,000 in annual sales, then enter ingredients, staff and other running costs into the appropriate fields. Compare gross and net margins after increasing one cost. A healthy gross margin does not protect the business from excessive overheads.

    • Celebrating a strong gross margin while overheads quietly consume the net.
