There is no single pension contribution amount that is right for everyone. How much you should contribute depends on your income, your current finances, how much you have already saved and the retirement you want to achieve.
A useful way to approach the question is from two directions:
What can I afford to contribute today?
What do I need to contribute to reach my retirement goal?
Ideally, these two figures will be reasonably close. If they are not, the difference helps identify whether you need to increase contributions over time, adjust your retirement target or consider retiring later.
The first approach starts with your finances today.
Your pension is important, but contributions need to be affordable alongside your normal living costs, debts, emergency savings and other financial commitments.
Start by considering your monthly income and expenditure:
Monthly income
- Essential expenditure
- Debt repayments
- Short-term savings and other commitments
= Amount potentially available for pension contributions
You do not necessarily need to contribute all of the remaining amount. The objective is to find a contribution that is sustainable and that you are comfortable maintaining.
If you have a workplace pension, check how much your employer will contribute.
Some employers offer contribution matching, where increasing your own contribution causes your employer to contribute more as well.
For example:
Your contribution = 5%
Employer contribution = 5%
Total going into pension = 10%
If your employer would increase their contribution to 8% if you also increased yours to 8%, contributing more could be particularly valuable.
Before deciding how much to contribute, it is therefore worth checking the maximum employer contribution available to you. MoneyHelper specifically recommends checking whether your employer offers contribution matching.
The amount reaching your pension can also be greater than the amount it effectively costs you.
For example, under a relief at source arrangement, a basic-rate taxpayer can make a £80 personal contribution and normally have £20 basic-rate tax relief added, resulting in £100 being invested into the pension. Higher and additional-rate taxpayers may be able to claim further relief depending on their circumstances.
This means it is useful to distinguish between:
What comes out of your pocket
and
What actually goes into your pension
when deciding what you can afford.
If the amount you can afford today is lower than you would ideally like to contribute, that does not mean you should do nothing.
You could start with an affordable amount and plan to increase it when your circumstances improve.
For example, you might review your contribution:
when you receive a pay rise
when a loan or mortgage payment ends
when your expenditure falls
when you change jobs
once a year as part of a financial review
Small increases made over a long period can make a meaningful difference because contributions have more time to benefit from potential investment growth.
The second approach works backwards.
Instead of asking "What can I afford?", ask:
"What retirement income do I want, and how much do I need to contribute now to get there?"
This requires a few assumptions.
Choose your target retirement age.
For example:
Current age = 35
Target retirement age = 65
Time until retirement = 30 years
The longer you have until retirement, the longer your contributions have to potentially grow.
Think about what you would like your retirement to look like and how much monthly income you may need to support it.
Consider expenses such as:
household bills
food and everyday spending
holidays and travel
hobbies and leisure
transport
housing costs
helping family
unexpected expenditure
Your spending in retirement may be very different from your spending today. For example, you might no longer have commuting costs or pension contributions, while you may want to spend more on travel and leisure.
MoneyHelper recommends estimating your likely retirement costs rather than relying solely on a percentage of your current salary.
Your private pension may not need to provide your entire retirement income.
Consider other expected sources, including:
State Pension
Workplace pensions
Personal pensions
Defined benefit/final salary pensions
Other investments or retirement income
For example:
Desired retirement income = £3,000 per month
Expected State Pension = £1,000 per month
Required from private pension = £2,000 per month
The figures used should reflect the income expected at the relevant retirement ages and whether the amounts are before or after tax.
Once you have established the amount of income your private pension needs to provide, you can estimate the pension fund required at retirement.
This will depend on assumptions including:
retirement age
how long the pension needs to last
expected investment growth
pension charges
desired monthly income
other retirement income
inflation
The result gives you a target pension value at retirement.
Once you know your target pension value, you can estimate how much needs to be contributed each month to reach it.
The calculation can take account of:
Current pension value
Existing monthly contributions
Employer contributions
Tax relief
Expected investment growth
Pension charges
Time until retirement
This produces a target monthly contribution.
You can then compare that figure with what you are currently contributing.
For example:
Current contribution = £300 per month
Calculated contribution required = £500 per month
Contribution gap = £200 per month
You now have something much more useful than a general rule of thumb: you know approximately what needs to change to improve the probability of reaching your goal.
The most useful pension contribution decision comes from comparing the two figures:
Affordable Contribution = What you can comfortably contribute today
Target Contribution = What you are estimated to need to contribute to achieve your retirement goal
If: Affordable Contribution ≥ Target Contribution
You appear to be contributing enough, based on the assumptions used. You should still review the calculation regularly because investment performance, inflation, income and retirement plans can change.
If: Affordable Contribution < Target Contribution
You have identified a potential retirement funding gap.
That does not necessarily mean you need to find all of the difference immediately.
You could consider:
gradually increasing contributions
contributing some or all of future pay rises
maximising employer contribution matching
making additional contributions when affordable
reviewing the retirement income target
changing the planned retirement age
reviewing existing pensions and charges
The important thing is that you now understand the difference between what you are currently able to save and what your retirement objective is estimated to require.
Rather than asking:
"What percentage of my salary should I put into my pension?"
consider asking two better questions:
"How much can I comfortably afford to contribute?"
and
"How much do I need to contribute to achieve the retirement I want?"
Your pension plan can then be built around closing any gap between the two.
There are also tax rules and allowances to consider when making larger contributions.
For the 2026/27 tax year, the standard pension Annual Allowance is £60,000, although a lower allowance can apply in certain circumstances, including for some higher earners and people who have flexibly accessed defined contribution pensions.
Tax relief on an individual's personal pension contributions is also subject to earnings-related rules. HMRC states that tax relief is generally available on private pension contributions up to 100% of annual earnings, subject to the applicable rules.
The value of your investment can fall as well as rise and is not guaranteed.
