How it works
- Revenue = price × units
- Gross profit = (price − unit cost) × units
- Net profit = gross profit − fixed costs
- Gross margin = gross profit ÷ revenue × 100; net margin = net profit ÷ revenue × 100
- Profit per unit = net profit ÷ units (fixed costs spread across every unit sold)
Use figures for one period — a month or a year — so fixed costs and units match.
Example
You sell 400 candles a month at R250, each costing R140 to make, and your monthly fixed costs are R25,000.
Revenue is R100,000; gross profit is (250 − 140) × 400 = R44,000 (44% gross margin); net profit is 44,000 − 25,000 = R19,000 (19% net margin).
How many candles before you start making money? See the break-even calculator.
Frequently asked questions
What is the difference between gross profit and net profit?
Gross profit is revenue minus the direct cost of the goods you sold. Net profit also subtracts your fixed or operating costs, such as rent, salaries and software, for the same period.
Should I include VAT?
If you are a registered VAT vendor, use VAT-exclusive prices and costs — the VAT you collect is paid over to SARS and isn’t your revenue. If you’re not registered, VAT you pay on purchases is part of your cost.
Is this profit before or after tax?
Before income tax. For a fuller picture with several income and expense lines and an optional tax estimate, use the Profit & Loss Calculator.
