Factors used by USS

What they are and how they're used

Factors are numbers we use to calculate several different things in relation to your Retirement Income Builder pension, like if you retire early or late. They allow us to work out how much pension to pay you.

If you’re paying in to USS (an active member), below are the most common factors we use and some examples of how they are used.

The factors set out below are set by the trustee, having taken advice from the Scheme Actuary. The factors are reviewed regularly to make sure they remain appropriate, taking into account (amongst other things) the Scheme Rules, legislation, economic factors and the approach to funding. We will continue to review and update our factors as appropriate.

As such, these factors are subject to change from time to time.

The factors on this page and the examples below apply for retirements from 1 April 2024 onwards. For the early retirement factors, a new set of factors will be implemented from 1 October 2024. We have provided details of the current factors and how they will change on 1 October 2024. We have also provided examples of retiring early now compared to retiring on or after 1 October 2024.

All of the examples are for illustration purposes only and the factors are subject to change from time to time. The examples and the factors should not be relied upon when making any decisions in relation to your USS benefits and/or retirement.

Taking your pension early - early retirement factor

Please note: New early retirement factors will be implemented from 1 October 2024 for early retirements on and from this date.

These factors are used to reduce your Retirement Income Builder pension payments when you retire early before your Normal Pension Age (NPA) as you’ll be receiving your pension for longer. The amount of pension you’d expect at your NPA is multiplied by the percentages shown below for the number of years and months before your NPA.

Note that the normal minimum pension age at which a member can retire early (unless retirement is due to incapacity) is age 55 and this is due to rise to age 57 on 6 April 2028.

Working past your Normal Pension Age - late retirement factors

Please note: This may not apply if you are no longer paying in to USS. See your options at different ages and stages for more information.

This factor is used to increase your Retirement Income Builder when you retire late, after your Normal Pension Age (NPA) as you’ll be receiving your pension for a shorter length of time. The amount of pension you’d expect at your NPA is multiplied by the number listed below for the number of years and months after the NPA that you retire.

This is a little more complicated as there are different factors for the different periods for when you reached and exceed your NPA. These are defined as pre-April 2016, April 2016-October 2020 and post October 2020. The NPA changed from 65 to 66 on 6 October 2020 (and will continue to rise in line with the State Pension age going forward).

  • If you reached age 65 before 1 April 2016, and are still paying in to USS, your late retirement factor would be a combination of all three columns.
  • If you reached age 65 between 1 April 2016 and 30 September 2020, and are still paying in to USS then benefits built up before age 65 late retirement factor would be a combination of two tables: April 2016-October 2020 and Post October 2020.
  • If you reached or will reach age 65 after 30 September 2020, and are still paying in to USS, then benefits built up before 1 October 2020 will receive a late retirement uplift based on how long after age 65 you’ve remained in the scheme, and this late retirement factor would be from the Post October 2020 table.
  • If you reached or will reach age 66 after 30 September 2020, and are still paying in to USS, then benefits built up from 1 October 2020 to age 66 will receive a late retirement uplift based on how long after age 66 you’ve remained in the scheme, and this late retirement factor would be from the Post October 2020 table.

The Post October 2020 factors are calculated differently from the other periods. These are compound calculations – multiplying the factor by itself for the number of months past NPA that you retire, and that amount by the amount of pension you’d expect at your NPA.

Taking less pension and more cash lump sum at retirement – commutation factor

This factor would be used when you’re using some of your Retirement Income Builder pension to increase your cash lump sum at retirement. The factor used is dependent on the age you retire. This factor is reviewed regularly. The next review date will take place later this year with any changes implemented from 1 April 2025.

To calculate the lump sum obtained by the exchange, we multiply the amount of pension to be exchanged by the relevant factor.

Taking more pension and less cash lump sum at retirement – reverse commutation factor

This factor would be used when you’re swapping some, or all, of your cash lump sum for extra Retirement Income Builder pension. The factor used is dependent on the age you retire. These factors are reviewed at least annually. The next review date will take place later this year with any changes implemented from 1 April 2025.

The amount of cash lump sum you’re exchanging for extra pension would be divided by this factor to create an extra pension amount.

Converting your Prudential Money Purchase Additional Voluntary Contribution (MPAVC) savings to extra Retirement Income Builder pension

As of 1 April 2022, members no longer have the option to convert their Investment Builder savings into additional Retirement Income Builder pension. This doesn't impact any MPAVCs currently held with Prudential or any MPAVCs with Prudential transferred into the Investment Builder, these savings can still be converted into additional Retirement Income Builder pension.

This factor would be used when you’re using your MPAVCs with Prudential, or MPAVCs you’ve moved from Prudential into the Investment Builder, to create extra pension in the Retirement Income Builder. The factor used is dependent on the age you are when the conversion is applied. This factor is reviewed monthly based on market conditions and other influences.

The amount you’re converting would be divided by the relevant factor to create an extra annual pension. If you convert the fund into annual pension this will also increase your spouse’s or dependant’s pension on the event of your death.
