Corrections Policy
Last updated: June 9, 2026
We aim to be accurate, but rules are complex and they change. If something looks wrong, we want to know and fix it.
How to report an error
Email hello@online-calc.com with:
- The calculator or page (a link is ideal).
- The exact inputs you used.
- The result you received and the result you expected.
- An official source for the expected figure, if you have one.
What happens next
- We acknowledge credible reports, usually within a few business days.
- We reproduce the issue and check it against the official source.
- If confirmed, we correct the calculation or content and refresh the calculator's verified date.
- For significant factual corrections, we note what changed so the record is transparent.
Estimates versus errors
Some tools are clearly labeled as estimates or pre-checks because the underlying rules vary by location or personal circumstances. A figure being an estimate is not an error; we still welcome reports where an estimate looks materially off. For how we build and verify tools, see our Methodology and Editorial Policy.
