Types of Issues We Handle
Formula error — The calculator produces a mathematically incorrect result based on the inputs given. This is our highest priority.
Wrong unit conversion — Metric or imperial output is off, or units are misapplied in the calculation.
Incorrect assumption — The formula is correct but uses a default value — an interest rate, activity multiplier, or constant — that no longer matches the current accepted standard.
Broken calculator — The calculator does not load, inputs do not respond, or the result field stays empty.
Display or layout issue — Formatting, overlapping elements, or readability problems on a specific device or browser.
Typo or content error — An incorrect label, unit name, description, or spelling mistake on a calculator page.
What Happens After You Submit
- We read your report and identify the calculator and inputs involved.
- We reproduce the issue and check the formula against the authoritative reference source.
- If a genuine error is confirmed, we correct the calculator and update the page.
- We reply to let you know the outcome — whether it has been fixed, explained, or is under further review.
