Lump Sum Calculator

Did you know you can take up to 30% of the value of your Unified Scheme pension in cash at retirement?
You do this by exchanging some of your annual pension for cash.

You can use this modeller to see how the amount of cash lump sum you take could affect your pension. Or if you know how much pension you want to receive each year, you can see how this will affect the amount of cash lump sum you can take.

To use the modeller you need to be an active member of the Unified Scheme or a deferred member who was an active member of the Scheme on or after 1 April 2012. Click the icon for more information about each field.

Please be aware that any results you produce from this modeller are for illustrative purposes only. The final and definitive calculations will be performed by the Public Sector Pensions Authority.

  1. The calculations are based on the current rules of the Unified Scheme. To take a cash lump sum you will need to give up some of your pension, the PSPA Unified Scheme page provides further details about your benefits and how they are calculated.
  2. In most cases, your pension lump sum will be tax-free. However, if tax laws change in the future, this may also change.
  3. Dependants' benefits are based on your original pension entitlement and are not affected by the amount of cash lump sum taken.
  4. Your pension will increase every year in line with price inflation. If inflation is zero, pensions in payment will not increase.
  5. This version of the lump sum modeller is only for use by active members of the Unified Scheme and deferred members who were an active member of the Scheme on or after 1 April 2012.
  6. It is recommended that you take independent financial advice when considering your retirement options.
