How to calculate your state pension

State pension is based on qualifying years of contributions, not on how much you earned. You need a minimum number of years to get anything and a full record to get the maximum, with the amount scaling pro-rata in between.

The rule

State pension = full rate × (qualifying years ÷ years needed for the full rate)

  3. 3Divide by the number of years required for the full amount and multiply by the full rate.
  4. 4Check whether buying voluntary contributions for gap years is worthwhile.

What trips people up

  • Career breaks, low-paid part-time work and time abroad commonly create gap years.
  • Voluntary contributions often pay for themselves within a few years of retirement.
