Accuracy tests
408 of 408 checked figures match the official calculators. This page was generated on 19 October 2026 from the same test cases that must pass before any release.
We type each case into the government's own calculator, record what it shows, and store it with the date. Our engine then has to produce the same figure, within the stated tolerance, or the site isn't published. If you find a case where we differ from an official source, please tell us.

Known, deliberate differences
- UK: GOV.UK's estimator shows monthly National Insurance as the annual figure divided by 12. Payroll (and WagePrism) works it out for each month against the monthly threshold, so the two can differ by a few pence a month.
- Australia: annual figures are the tax for the year; pay-packet figures follow the ATO withholding formulas, which round each pay to the dollar.
