Terms of Use

The service

Crown Calculator is run by Abdul Manan and provides free online calculators and explanations for general information. You don't need an account to use it.

Accuracy

Results are calculated with standard formulas and rounded for display, usually to two decimal places. Care is taken to keep them correct, but no guarantee is given that every result or explanation is free of errors. Check important figures independently before relying on them. The calculators are not a substitute for professional, medical or engineering advice; see the disclaimer.

• Don't use automated tools to make large numbers of requests, scrape the site or interfere with how it works for others.
• Don't attempt to gain unauthorised access to the site or the systems behind it.
• Don't click on ads or interact with them in any way intended to inflate their numbers.
