Useful next calculations
When to use this calculator
- Before pricing a job, setting margin targets or reviewing hiring costs.

A worked example
These are the example figures the calculator opens with.
| Input | Value |
|---|---|
| Revenue ($) | $50,000 |
| Total Costs ($) | $35,000 |
For those figures the calculator returns:
- Profit: $15,000.00
- Margin: 30.00%
- Markup: 42.86%
Common mistakes
- Using an assumption that is not supported by a current local quote, bill, statement or official source.
- Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- Mixing monthly and annual inputs without converting them consistently.
- Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.

Gross margin = (revenue - cost of goods sold) / revenue - it shows product profitability. Operating margin deducts overheads and operating expenses too. Net margin deducts interest, tax, and everything else, giving the final bottom-line margin. A healthy small business typically targets 50%+ gross, 15-20% operating, and 10%+ net depending on sector.
