Contact us
CalQlate is run by a small team. There is no contact form, no ticket queue and no chatbot — just an email address that a person reads.
Found a wrong number?
This is the message we most want to receive. Please include the calculator name, the exact values you entered, the result you got, and the result you expected. Every calculation is backed by automated tests against published reference values, so a genuine discrepancy is something we will fix quickly and want to know about.
Want a calculator that is not here yet?
Tell us which one and what you would use it for. We prioritise by what people actually ask for, and requests that describe a real situation are much more useful than a bare name.
What we cannot help with
We cannot interpret your results for you, advise on your health, or comment on your financial situation. Those need a qualified professional who knows your circumstances — see our disclaimer.
