Questions, corrections or calculator ideas? Get in touch.
Use the contact option that best matches your message. Clear, specific feedback helps us investigate calculator issues and improve the site.
We welcome messages about calculator accuracy, confusing inputs, broken links, usability problems, accessibility concerns, missing calculators and general website questions. If you are reporting a calculation issue, including the exact values you entered is usually the fastest way to make the report useful.

sonocalculatorbusiness@gmail.comReporting a calculator problem
If a result looks wrong, please send enough information for the calculation to be reproduced. A message such as “the calculator is wrong” is difficult to investigate, while a short example with the exact inputs makes it much easier to check the formula, units and rounding behavior.
This information helps distinguish a genuine calculation problem from a unit mismatch, a different formula convention or an assumption that needs clearer explanation.
Suggesting a new calculator
New calculator ideas are welcome. The most useful suggestions describe the real task the calculator should solve rather than only providing a title. Tell us what someone would normally know before using the calculator, what answer they need, and whether there are important options or units that should be supported.
Examples of helpful details include whether a tool should support metric and US customary units, whether a rate should be entered by the user, whether results should be shown per month or per year, or whether there are multiple accepted calculation methods.
Questions about a result
We can receive feedback about how a SonoCalculator page works and whether the explanation is clear, but the website is not a substitute for a professional who can evaluate your complete personal situation. We cannot determine whether a specific medical treatment, legal decision, tax filing position, investment, building method or lending decision is right for you.
For high-stakes decisions, use the calculator as a starting point and verify the result against the authoritative rules, documents, professionals or service providers that apply to your situation.
Privacy when you contact us
Please avoid sending passwords, authentication codes, full payment-card details, government identification numbers, medical records or other highly sensitive information. Calculator feedback normally requires only the inputs relevant to the calculation and a description of the problem.
For information about website data practices, review the Privacy Policy and Cookie Policy.
What kinds of messages are most useful?
- A calculator produces a result that does not match the stated formula.
- A unit label, percentage, currency symbol or result description is confusing.
- A page behaves incorrectly on mobile or has a broken link.
- An edge case causes an error, impossible value or misleading output.
- A calculator explanation is missing an important limitation or assumption.
- You have a practical calculator idea that would help visitors solve a recurring problem.
We value precise feedback because it helps us improve both the calculation and the explanation around it.
General website inquiries
For questions that do not fit the categories above, use the general contact address. Business inquiries should use the dedicated business address so they can be separated from calculator-correction reports.
