Our original analysis, tables and charts may be reused with credit to IsMyPayRight and a link to the relevant report. Keep the version, tax year, source-data status and assumptions alongside the figure. Official source material retains its own licence terms.

These are modelled annual comparisons. Pension choices, household support and a payslip’s year-to-date history can change an individual result. Each report sets out its full scope.

We publish dated versions so a finding remains checkable. For a correction or a question, use our editorial and corrections process. Read our calculation methodology for the wider approach.
