Get in touch.
Have a question, spotted something that looks wrong, or want a calculator that does not exist yet? Send an email and it comes straight to me.
This inbox is read by me, Jean, the person who builds the site. Include the calculator name and what you were trying to work out so I can help quickly.
Send an email ›What you can reach me about
Three good reasons to write.
Ask a question
Not sure which calculator to use, or how to read a result? Ask away and I will point you the right way.
Report a wrong result
Accuracy comes first. Send the inputs you used and the answer you expected, and I will check the maths and fix it.
Request a calculator
Need a tool that is not here yet? Tell me what it should do. Many calculators on the site started as a single email.
Before you email
Response time
freecalculators.pro is run by one person in Malta, so replies usually take a few days rather than minutes. Every message is read, and the most common questions tend to turn into clearer help text or a new feature on the site.
For how your information is handled when you get in touch, see the privacy policy.
Prefer to just email?
Send your question, correction or calculator idea straight to my inbox and I will get back to you.
