Report an Incorrect Calculator Result

Every calculator on AjaxCalculators is individually tested and reviewed before or after significant publication changes.

However, software bugs, unusual input combinations, changes in reference information, or differences between accepted calculation methods can occasionally produce unexpected results.

If you believe a calculator is producing an incorrect result, please include as much of the following information as possible:

• Calculator name

• Calculator URL

• Values entered

• Units selected

• Result displayed

• Result you expected

• How you calculated the expected result

• Relevant formula, methodology, or source

• Screenshot, if useful

These details help the Admin reproduce the calculation and investigate the issue accurately.

Suggest a Better Formula, Method, or Source

Some calculations have more than one recognised formula or methodology.

If you believe a calculator uses an outdated method, incorrect reference value, or a less appropriate source, you are welcome to suggest an improvement.

Please include:

• the calculator URL;

• the method currently used, if known;

• the alternative method you recommend;

• a reputable or authoritative supporting source; and

• a short explanation of the difference.

Suggestions are reviewed before any changes are made.

• calculator not loading;

AjaxCalculators was created to help people solve real everyday problems.

If there is a calculation you regularly need and believe would genuinely help other users, you are welcome to suggest it.

• expected inputs;

• expected result;

New calculators are considered based on their usefulness, clarity of methodology, and whether AjaxCalculators can provide genuine value for the user.

Response and Review Process

Messages are reviewed by the Admin according to their subject.

For calculator-error reports, the Admin may attempt to reproduce the reported result and compare it with the calculator’s formula, methodology, source, or expected behaviour.

For technical issues, the Admin may test the affected functionality on different devices or browsers.

For source or methodology suggestions, the supporting reference may be reviewed before deciding whether a change is appropriate.

Submitting a suggestion or report does not guarantee that a calculator or page will be changed, but genuine issues are taken seriously.
