Report an error

Found a calculator producing a wrong result, a figure that is out of date, or a page that looks broken? This is the most valuable message you can send us. Please include the calculator name, the inputs you used, what you expected, what you got and — if you can — the source that supports your figure. Corrections are made at the source dataset or engine and noted on the page.

Request a calculator or feature

Missing a calculator you use, or want an option added to an existing one? Tell us the job you are trying to do. The roadmap lists everything planned, and we prioritise requests that come up repeatedly and can run entirely in the browser.

Privacy questions

Questions about how CalculatorManager handles data, or a request relating to your rights under data-protection law. Short version: we do not receive anything you type into a calculator, so there is normally nothing for us to look up, export or delete — see the Privacy Policy.

admin@calculatormanager.com — subject line “Privacy enquiry”.

For a copyright notice or counter-notice, use the procedure on the Copyright & DMCA page so the required details are included.

Why there is no contact form

A form would mean a script that handles and stores what you type. This site collects nothing, and we would rather keep that promise consistent than add one exception. Email reaches a person; you will usually hear back within two to three working days.

Before you write

• Check the calculator's own FAQ and “what this does not model” section — most questions about a result are answered there.
• Individual financial, tax, medical or legal advice is something we cannot give — see the Disclaimer.
• Use the search box in the header; the calculator you want may already exist under a different name.
