Contact Us
We'd like to hear from you.
Whether you've spotted an error in a calculation, have an idea for a new calculator, or just want to say hello, here's how to reach us.
For all enquiries, feedback, and error reports, write to us at support@calculatormax.example. We try to respond to every message, though response times may vary depending on volume.
Reporting a calculation error
If you believe a calculator is producing an incorrect result, please include the following in your message so we can investigate quickly:
- The name of the calculator page (and its URL, if possible)
- The exact input values you entered
- The result you received, and what you expected instead
Suggesting a new calculator
CalculatorMax is actively growing. If there's a calculator you'd find useful that isn't on the site yet, let us know what it should calculate and any formula or example you have in mind — we review every suggestion.
