How This Calculator Works

This calculator uses official 2026/27 Agenda for Change data, HMRC tax and NI thresholds, and NHS Pension Scheme contribution rates. Figures are estimates based on standard assumptions — your actual amounts may differ depending on your individual tax code, trust-specific policies, or other personal circumstances. Always check with your payroll department or HR for precise figures.
