Reporting an error

The fastest way to get a correction made is to include:

1. The full page URL (for example https://ameti.capital/tools/margin-markup/).
2. The inputs you used, if it concerns a calculator. The download button saves them as a text file you can paste into your email.
3. The result you saw and the result you expected, with your working if you have it.
4. The source you are relying on, if you think a definition is wrong.

Confirmed errors are corrected and the page's "last reviewed" date is updated.

What we can help with

• Errors in formulas, tables, worked examples or calculator behavior
• Broken links or accessibility problems
• Suggestions for a pricing-arithmetic topic we have not covered

What we cannot help with

We do not set prices for individual businesses, review business plans, or give accounting, tax, legal, lending or investment advice, and we do not offer capital advisory, succession or M&A services. For decisions about your own business, consult a qualified professional.
