2Business calculator FAQ
- What's the difference between markup and profit margin?
- Markup is profit as a percentage of cost; profit margin is profit as a percentage of the selling price. A product that costs $50 and sells for $75 has a 50% markup but a 33.3% margin. Use the markup and profit margin calculators to convert between them.
- How do I set a freelance or consulting rate?
- Work backwards from the income you need: add business costs and taxes, then divide by the hours you can realistically bill. The consulting rate, service pricing, and freelancer tax calculators walk through each step.
- Do the tax calculators replace an accountant?
- No. The freelancer tax and quarterly tax calculators estimate federal taxes using the published figures for the stated tax year and simplify some rules. Use them for planning, and confirm filings with a tax professional.
