How going part-time can impact your DB pension

Here are a few things to consider as a DB member if you're thinking about reducing your hours at work
This article is for active defined benefit (DB) members of the Railways Pension Scheme (RPS).
You might be thinking about reducing your hours to achieve a better work-life balance, spend more time with family, ease into retirement, or simply have more flexibility in your week.

Whatever your reason, you might be wondering what will happen to your pension.

The good news is that the pension you've already built up is protected. But working fewer hours could affect:

  • how much pension you build up in future
  • how much you pay into your pension
  • any Additional Voluntary Contributions (AVCs) you're making
In this article, we'll explain some of the main ways reducing your hours could affect your pension to help you decide whether part-time work is right for you.

What happens to the pension you’ve already built up?

The pension you've already built up doesn't disappear because you decide to work fewer hours. The benefits you've earned before moving to part-time hours will still belong to you and are based on your pensionable salary and service at that time. 

Going part-time will only affect how much pension you build up from that point onwards.

Will you build up less pension if you work part time?

You could build up your pension benefits more slowly.

That's because we calculate your pension benefits using:

  • your full-time rate of pay
  • the hours you've worked
  • the number of years you've worked
If you go part-time, your pension benefits will be based on your full-time rate of pay, but they're adjusted to reflect the hours you now work.

For example:
  • 20 years of working 40 hours a week (full time) = 20 years’ pensionable membership
  • 20 years of working 20 hours a week (part time) = 10 years’ pensionable membership
If you change your working hours during your career, we calculate each period separately and then add them together to work out your total membership.

That means the longer you work part-time, the greater the impact could be on the pension benefits you build up in the future.

How could your pension contributions change?

When you work part-time, your employer will reduce your pension contributions to reflect the hours you've worked.

We calculate your contributions using the full-time contribution rate for your job and then adjust that amount to reflect your part-time hours.

For example, if you work half of your employer's full-time hours, you'll pay about half of the full-time contribution amount. 

Your employer will change your contributions the first payroll date after:

  • you start working part-time
  • your working hours change, or
  • you return to full-time work. 
This means you'll usually pay less into your pension when you reduce your hours, but you'll also build up pension more slowly

What happens to your Additional Voluntary Contributions (AVCs)?


If you pay AVCs as a percentage of your pay, reducing your hours could reduce the amount you contribute each month.

If you pay a fixed amount, your contributions may stay the same.

The impact will depend on how you set up your AVC contributions. If you pay AVCs, check how your arrangement works before you reduce your hours.

You can also read our guides for BRASS and AVC Extra members for more information about contributions.

What should you check before going part time?

Before making a decision, you may want to: 

  • ask your employer how your pensionable pay and contributions would change
  • check how working fewer hours could affect the pension benefits you build up in the future
  • check how any Additional Voluntary Contributions (AVCs) you make could be affected
  • get an estimate of your pension benefits through your myRPS account

Your employer can explain how a change in your hours and pay would affect your contributions and the benefits you build up for your DB pension.
