Terms of use

Using the tools

You may use the tools for your own everyday and business calculations. Enter accurate numbers and check that the tool’s assumptions match your situation.

Estimates and limitations

Results are arithmetic estimates, not professional financial, accounting, legal or tax advice. We do not guarantee sales, profit or suitability for any official submission. No tool applies local tax or labour rules automatically.

Check important decisions

Compare important results with your own records or a qualified adviser. Rounding, omitted costs, changing prices and incorrect units can affect the outcome.

Availability and content

Features and explanations may be updated or unavailable. Do not misuse the site, interfere with access or present illustrative examples as guaranteed earnings. These terms do not exclude rights that cannot lawfully be excluded.
