Reporting a Calculator Problem
If you believe a calculator is producing an incorrect or confusing result, the most useful report includes:
- the name of the calculator;
- the values you entered;
- the units you selected;
- the result shown;
- the result you expected, if known;
- any warning or message that appeared.
Those details make it much easier to reproduce the issue and determine whether the problem is in the formula, units, rounding, validation, explanation, or an assumption that needs to be made clearer.
Suggesting an Improvement
You can also contact us when a calculator is mathematically correct but difficult to understand.
Useful suggestions include:
- an important input that is unclear;
- a unit that would make the tool more useful;
- an edge case the calculator does not explain well;
- a result that needs a clearer breakdown;
- terminology that could be easier to understand.
We may not add every requested feature. A calculator is often more useful when it asks for only the inputs genuinely needed for its purpose.
