Contact
Have a question, spotted a wrong number, or want to use a calculator on your own site? Here is how to reach us.
The best way to reach us is [email protected]. Use it for general questions, data corrections, privacy requests, embedding and press. We read every message and usually reply within a few working days.
Report a wrong number or a bug
Accuracy matters to us. If a result looks off, email [email protected] and tell us the country, which calculator, the input you used and the figure you expected. We check it against the official primary source and fix it if it is wrong.
Embed or reuse a calculator
Every calculator has a "copy for your site" option that gives you a ready-made embed. If you need something specific for your site or article, get in touch and we will help.
Who you are contacting
paycalceu is operated by Radim Sekera (sekera.dev), who is also the data controller for the processing described in the Privacy Policy.
