Methodology
This tool assumes:
- 2025-26 Small Profits Threshold £6,845 — below this, Class 2 NI is voluntary at £3.50/week (~£182/year).
- A qualifying NI year requires sufficient contributions in that tax year (Class 1, Class 2, or Class 3 voluntary).
- Full new State Pension typically requires 35 qualifying years; 10 years for any State Pension at all.
- New Style ESA contribution conditions look at the two complete tax years before the year you claim.
- If you have other qualifying NI sources (e.g. employment Class 1, NI credits while claiming UC/Carer's Allowance), voluntary Class 2 may be unnecessary.
