Should You Increase Your Pension Contributions After a Pay Rise?

A pay rise is one of the best moments to increase your pension contribution, precisely because you haven’t adjusted your spending to the new amount yet. Here’s the case for doing it, and how to think about how much - a mirror image of the challenge facing self-employed savers without a fixed salary to benchmark against, who have to build the same discipline in without a single pay-rise moment to anchor it to.

Why timing a pension increase to a pay rise works so well

The reason so many people never seem to save more even as their income grows is ‘lifestyle creep’ - spending rising automatically to match income, without a deliberate decision to do so. If you increase your pension contribution by the same percentage as your pay rise, your take-home pay stays roughly where it was before the rise, so there’s no adjustment to feel - you simply never get used to spending the extra money in the first place.

A simple worked example

Say you earn £35,000 and get a 5% pay rise to £36,750 - an extra £1,750 a year. If you increase your pension contribution by roughly that same amount, you keep your take-home pay close to what it was before the rise, while adding £1,750 a year (plus tax relief) to your pension - money you’d likely never have missed, since you hadn’t yet adjusted your budget to include it.

Check whether it also helps with your employer match

If your employer matches contributions up to a certain percentage and you’re not yet contributing enough to get the full match, a pay rise is a natural moment to close that gap - see our separate article on making sure you’re not leaving employer match on the table.

Consider salary sacrifice if it’s on offer

If your employer offers salary sacrifice, directing part of a pay rise into your pension this way saves National Insurance as well as getting standard tax relief - see our salary sacrifice series for the full mechanics, including how this interacts with thresholds like the £100,000 Personal Allowance taper if the rise pushes you close to it.

Watch for threshold effects, not just percentage increases

If a pay rise pushes your income past £50,270 (the higher-rate threshold) or £100,000 (where the Personal Allowance taper begins), increasing pension contributions can do double duty - reducing your tax bill on the portion of income that’s now taxed at a higher rate, or restoring allowances that would otherwise be lost entirely (see our articles on the 60% tax trap and Tax-Free Childcare thresholds).

It doesn’t have to be all-or-nothing

You don’t need to redirect 100% of a pay rise into your pension to benefit from this approach - splitting it, for example half toward pension contributions and half toward take-home pay, still meaningfully increases your retirement saving without feeling like you’ve received no benefit from the rise at all.

The bottom line

A pay rise is one of the lowest-friction moments to increase pension contributions, because you’re adjusting from a baseline you haven’t yet gotten used to spending. Even directing a portion - rather than all - of a pay rise toward your pension compounds meaningfully over a working life.
