Flagging a correction
If you’ve spotted a figure, formula, or rate that looks incorrect or out of date, this is the fastest way to get it fixed. Please include:
- The specific page (calculator name and country)
- The figure or formula you believe is wrong
- Where possible, a link to the official source showing the current correct figure
See our Editorial Policy for how corrections are reviewed and our Corrections log for recent updates.
