What to Include in Your Message
A quick note is fine, but a few details help us fix things faster. If you're reporting a calculation that looks wrong, tell us which calculator, the exact numbers you entered, and the result you expected instead — ideally with a link to the source (a tax table, a published rate, a textbook formula) that shows the correct figure.
If you're requesting a new calculator, tell us what it should do and, if you know it, the formula it should use. If you spotted an out-of-date rate or a broken link, the page URL is all we need.
What People Usually Write In About
- A calculation that looks wrong, or a formula that doesn't match a trusted source
- A rate, bracket, or fee that's changed since we last checked it
- A calculator you'd like to see added to the site
- A broken link, a confusing explanation, or a typo
- Advertising, partnership, or press enquiries
- A privacy or data request
How We Handle Reports
Every message goes to a real person on the editorial team, not a ticket queue. If you've flagged a possible error, we check it against the source the calculator is built on before making any change — that way a correction is always backed by something authoritative, not just a guess. Confirmed fixes are made promptly and the calculator's "last updated" date reflects the change.
We can't promise a reply to every message, but we read all of them, and reports that improve accuracy are the ones we act on fastest.
Email us: hello@calculatorplus.us
We read every message ourselves and reply as soon as we can — usually within a few days.
Frequently Asked Questions
How quickly will I get a reply?
We read messages as they come in and typically reply within a few days. Reports of a calculation error get priority, since accuracy is what this site is built on.
Do you take requests for new calculators?
Yes — tell us what the calculator should do, and the formula if you know it. We add tools based on how useful and how verifiable they are, so a request with a clear, sourced formula is more likely to get built.
I think a calculator gave me the wrong answer. What should I send?
Send the calculator's name, the exact inputs you used, the result you got, and the result you expected. A link to an authoritative source showing the correct figure or formula helps us confirm and fix it quickly.
Is there a phone number or live chat?
No — email is the only way to reach us. It lets us actually check a report against its source before replying, rather than guessing on the spot.
