How Much Should I Put in My Pension?
5 July 2026 · 4 min read
Nobody can tell you the exact right number to put into your pension without knowing your income, age, other savings, and what kind of retirement you want. But there are a few widely-used rules of thumb that give a sensible starting point, plus some practical trade-offs worth thinking through.
The "half your age" rule of thumb
One commonly used guide: take the age you started saving for retirement, halve it, and that's roughly the percentage of your pre-tax income you should aim to contribute each year (combining your contribution and your employer's) for the rest of your working life. Start at 30, and the rule suggests aiming for around 15%. Start at 40, and it suggests around 20%. It's a rough guide, not a rule — but it illustrates a real point: the later you start, the more you need to put away to catch up, because your money has less time to grow.
At minimum, get the full employer match
If your employer offers to match extra contributions above the auto-enrolment minimum — for example, matching your contribution up to a higher percentage if you choose to pay in more — that match is effectively free money. Before doing anything else with your savings, it is generally worth contributing at least enough to get the full match, since no investment return can reliably beat "instantly doubling your money."
Think in terms of income replacement, not a lump sum
Rather than aiming for a scary-sounding lump sum figure, it can be more useful to think about what percentage of your current income you'd like to replace in retirement. Many people aim for somewhere between half and two-thirds of their pre-retirement income, accounting for the fact that outgoings like commuting, mortgage payments, and saving itself usually reduce or disappear by then. Your pension provider's projection tool (usually in their app or annual statement) will show you an estimate based on your current contributions.
Balance pension saving against other goals
Pensions are extremely tax-efficient, but the money is locked away until at least your late 50s. If you have short-to-medium-term goals — a house deposit, an emergency fund, paying off high-interest debt — it can make sense to balance pension contributions against those, rather than maximising your pension at the expense of everything else. A common approach: build a small emergency fund first, pay down expensive debt, get the full employer pension match, then split further saving between pension and more accessible options like an ISA (see our pension vs ISA guide).
Small increases add up more than people expect
Because pension contributions are invested over long periods, small changes made early compound significantly by retirement. Increasing your contribution by even one or two percentage points in your 30s or 40s — something many people don't notice much in their take-home pay — can make a meaningfully larger difference to your eventual pot than the same increase made in your 50s.
Revisit the number as life changes
Your ideal contribution isn't a one-time decision. Pay rises, bonuses, and changes in your other financial commitments are all natural points to reconsider whether you can afford to increase what you're putting away — many people find it easiest to increase their pension contribution at the same time as a pay rise, before they get used to the extra take-home pay.
This is general information, not personalised financial advice. Rules and allowances change, and your right decision depends on your own circumstances — for anything that affects your money long-term, it is worth checking the current figures on GOV.UK or speaking to a regulated financial adviser (MoneyHelper offers free, impartial guidance).
Common questions
Is there a maximum I can put into my pension each year?+
Yes — there is an annual allowance on how much pension saving can benefit from tax relief each year, and a separate rule for very high earners. Most people are nowhere near these limits, but if you earn a high income or receive a large bonus, it is worth checking the current annual allowance on GOV.UK.
Should I prioritise my pension or paying off my mortgage?+
It depends on your mortgage interest rate versus your likely investment returns, and on your employer match. As a rule of thumb, get any free employer match first, since that is close to a guaranteed return no mortgage overpayment can match.
What if I cannot afford to increase my contribution right now?+
That is fine — even the auto-enrolment minimum, kept up consistently, builds a meaningful pot over a working life. Revisit your contribution level whenever your income increases rather than trying to jump to an ideal number immediately.
Does contributing more reduce my take-home pay by the same amount?+
No — because of tax relief, an extra £1 into your pension typically costs you less than £1 of take-home pay (the exact amount depends on your tax rate), which is part of why pensions are considered tax-efficient.
Do self-employed people need to think about this differently?+
Yes — without an employer contribution, self-employed savers only benefit from their own contributions plus tax relief, so many aim to save a higher percentage of income than employees do, often through a personal pension or SIPP.
