Pensions are the financial product most people
know they should care about and consistently
fail to engage with until it is too late. The
good news is that even modest increases to your
pension contribution today make a dramatic
difference to your retirement income — and cost
less than you might think after tax relief.
Here is a plain-English guide to where you
should be at each decade, and what to do if
you are behind.
The UK Pension Benchmarks
There is no single official figure for how
much you should have saved at each age, but
several widely-used guidelines give a useful
target. The most commonly cited is the Fidelity
rule of thumb:
By age 30: 1x your annual salary saved
By age 40: 3x your annual salary saved
By age 50: 6x your annual salary saved
By age 60: 8x your annual salary saved
By retirement: 10x your annual salary saved
So if you earn £40,000 per year, these
benchmarks suggest:
Age 30: £40,000 in your pension pot
Age 40: £120,000 in your pension pot
Age 50: £240,000 in your pension pot
These are targets, not rules. A third of UK
workers are significantly behind these
benchmarks — which means catching up is
more common than you might think.
How Much Are You Actually Contributing?
Under auto-enrolment, the minimum total
pension contribution is 8% of qualifying
earnings — 5% from you and 3% from your
employer.
The problem is that 8% is not enough to
meet the benchmarks above for most people,
particularly if you started saving late.
Here is what you actually need to contribute
at different ages to reach a comfortable
retirement income:
Starting at 22: 8-10% total contribution
Starting at 30: 12-15% total contribution
Starting at 40: 18-25% total contribution
Starting at 50: 30%+ total contribution
The later you start, the more you need to
save to catch up. The earlier you act, the
cheaper it is.
What Does Your Pension Cost You Really?
This is where most people are surprised.
Because of tax relief, pension contributions
cost significantly less than their face value.
For a basic rate taxpayer (earning under
£50,270), every £100 contributed to your
pension costs you just £80. The government
adds £20.
For a higher rate taxpayer (earning over
£50,270), every £100 contributed costs you
just £60. The government adds £40.
If your employer uses salary sacrifice —
where your contribution is taken before
tax and National Insurance — the saving
is even greater. You also save National
Insurance on the contribution, which adds
another 8% on earnings below the upper
earnings limit.
Here is the real monthly cost of increasing
your pension contribution on a £40,000 salary:
Increasing from 5% to 8%:
Additional gross contribution: £100/month
Additional cost to you: £80/month (basic rate)
Extra NI saving with salary sacrifice: £8/month
Real cost with salary sacrifice: ~£72/month
Increasing from 5% to 10%:
Additional gross contribution: £167/month
Additional cost to you: £134/month (basic rate)
Real cost with salary sacrifice: ~£121/month

At 30 — Build the Habit
If you are 30, the most important thing is
not how much you have saved — it is whether
you are saving consistently. The power of
compound growth means that £100 saved at 30
is worth significantly more at 65 than £100
saved at 40.
If you are behind the 1x benchmark, do not
panic. Focus on:
Maximising your employer contribution. Many
employers will match contributions beyond
the minimum — check your employment contract.
If your employer matches up to 8% and you
are only contributing 5%, you are leaving
free money on the table.
Switching to salary sacrifice if available.
The NI saving alone is worth the switch.
Increasing by 1% per year. Each time you
get a pay rise, increase your pension
contribution by 1%. You will never miss
money you never received.
At 40 — Accelerate
By 40 most people are at peak earning years
relative to their career stage. If you are
significantly behind the 3x benchmark, this
is the decade to close the gap.
Key actions at 40:
Find old pension pots. The average UK worker
has 11 jobs over their career. Old workplace
pensions from previous employers are
frequently forgotten. The government’s
Pension Tracing Service at gov.uk can help
you find them.
Consider consolidation. Multiple small pots
are harder to manage and may carry higher
charges. Consolidating into a single SIPP
gives you more control and potentially
lower fees.
Review your investment strategy. The default
funds in most workplace pensions are
conservative. At 40 you still have 25+ years
of growth ahead — a more growth-oriented
allocation may be appropriate.
At 50 — Make It Count
By 50, the State Pension is within sight
(currently payable at 66) and the choices
you make in this decade will define your
retirement income.
Key actions at 50:
Maximise contributions if you can. The
annual allowance for pension contributions
is £60,000 in 2026/27 or 100% of your
earnings, whichever is lower. Higher earners
who can afford to maximise this in the years
before retirement can significantly boost
their pot.
Check your State Pension forecast. Go to
gov.uk/check-state-pension. The full new
State Pension is £221.20 per week (£11,502
per year) in 2026/27. You need 35 qualifying
NI years to receive it in full.
Consider salary sacrifice more seriously.
If you are still working and your employer
offers salary sacrifice, the combined
income tax and NI saving at this stage
can be substantial — particularly if you
are a higher rate taxpayer.
What If You Are Behind?
Most people are behind the benchmarks.
That is the honest truth. Here is what to
do about it:
Do not try to catch up all at once. A
gradual increase of 2-3% per year is
more sustainable than a dramatic jump
that you cannot maintain.
Focus on your employer match first.
Always contribute at least enough to
get the maximum employer contribution.
Anything less is leaving free money
unclaimed.
Use the Payslp calculator to model the
impact. Before deciding on a contribution
level, calculate your take-home at
different percentages. The difference
between 5% and 8% is often less than
£60 per month on a £35,000 salary after
tax relief — far less than most people
expect.
Speak to a regulated financial adviser.
For significant pension decisions —
particularly around consolidation,
drawdown strategy or defined benefit
schemes — independent regulated advice
is worth the cost.
The Bottom Line
The best time to increase your pension
contribution was ten years ago. The second
best time is today.
Even a 1% increase, sustained over 20
years, makes a meaningful difference to
your retirement income. And thanks to
tax relief, that 1% costs you considerably
less than it appears.
