Quick answer
There is no universal pension target.
The pension you need depends on the income gap between what you want to spend in retirement and what you'll receive from other sources — particularly the State Pension.
The right question isn't "how big should my pension be?" It's "how much income does my pension need to provide, and for how long?"
Why your pension target is personal
Two people can have identical pension pots and completely different retirement outcomes.
One might have a full State Pension, a defined benefit pension from a previous employer, no mortgage and modest spending plans.
The other might have a reduced State Pension, no other guaranteed income, a mortgage still to pay and significantly higher spending expectations.
The same pension pot could be more than sufficient for the first person and nowhere near enough for the second.
That's why pension targets quoted online — "you need £500,000" or "aim for 10 times your salary" — can be misleading. They don't know your circumstances.
Steve's observation
I often meet people who are worried they haven't saved enough, but when we actually look at the numbers, they're in a much better position than they thought.
And I meet others who feel reassured by a pension balance that looks substantial, but haven't accounted for how much income they actually need or how long it needs to last.
The pension balance is only half the picture. The other half is what you're asking it to do.
Step 1 — Identify your income gap
Start with the retirement you want and what it will cost.
If you haven't done this yet, our completed guide How Much Money Do I Need to Retire? takes you through the lifestyle-first calculation.
Once you have an annual spending figure, subtract the income you expect to receive from other sources:
- State Pension;
- defined benefit or final salary pension income;
- rental income;
- or other reliable sources.
What remains is the income gap your pension needs to fill.
For example:
Desired annual income: £32,000
State Pension: £12,548
Income gap: £19,452 per year
That £19,452 is what your pension and other savings need to provide.
Step 2 — Understand how long the gap needs filling
The size of pension pot you need depends not just on the annual gap, but on how many years it needs to last.
Someone retiring at 55 may need their pension to last 35 years or more.
Someone retiring at 68 may need it to last 20 years.
The earlier you retire, the more your pension needs to provide — both because the gap period is longer and because State Pension may not begin for several years.
Pause for thought
- If you retire before State Pension age, your pension may need to provide considerably more income during the early years than it will later.
- Once State Pension begins, the amount your pension needs to provide each year may reduce significantly.
- This phased approach — higher withdrawals early, lower later — is one reason retirement planning is more complex than simply dividing a pot by years.
Step 3 — Estimate what pot you might need
Once you know the annual gap and the likely duration, you can start to estimate the pot required.
A simple approach is to multiply the annual gap by the number of years you expect to need it. But this ignores investment returns, inflation, charges and the variability of actual outcomes.
A more sophisticated approach considers:
- the investment return you might reasonably expect;
- inflation and how it affects spending over time;
- charges deducted from the pension;
- tax on withdrawals;
- and the risk that returns are lower than expected.
This is where retirement modelling becomes genuinely useful — testing different scenarios rather than relying on a single estimate.
The State Pension matters
For 2026/27, the full new State Pension is £241.30 per week, approximately £12,548 a year.
For a couple who each qualify for the full amount, that's potentially more than £25,000 a year between them.
That's a significant contribution to retirement income — and it substantially reduces the amount your private pension needs to provide.
But don't assume you'll receive the full amount. Your State Pension depends on your National Insurance record. Get your own forecast before building your plan.
Defined benefit pensions
If you have a defined benefit or final salary pension, it provides a guaranteed income in retirement rather than a pot of money.
That guaranteed income reduces the gap your defined contribution pension needs to fill.
For example, if your desired income is £35,000 and your defined benefit pension provides £15,000, your State Pension provides £12,548, the remaining gap is only £7,452 — a very different calculation from someone with no defined benefit pension.
If you have a defined benefit pension, make sure you understand what it will pay and when.
What if I have several pensions?
Add them together to understand your total pension provision.
You might have:
- a current workplace pension;
- one or more old workplace pensions;
- a personal pension;
- or a combination.
Each pension may have different features, charges and options. But for the purpose of understanding whether you have enough, the combined value is what matters.
If you've lost track of old pensions, our completed guide How Do I Find an Old or Lost Workplace Pension? explains how to trace them.
Coaching point
Write down these four things:
- Your desired annual retirement income
- Your expected State Pension (from your forecast)
- Any other guaranteed income
- The resulting annual gap
That gap is your pension's job description. Once you know what you're asking your pension to do, you can start to assess whether what you've saved is enough — and what you might need to do if it isn't.
What Should I Do Next?
Get your State Pension forecast. Add up all your pension values. Estimate your desired retirement income. Calculate the gap.
Then ask: can what I've accumulated reasonably fill that gap for the length of retirement I need to plan for?
If the answer is unclear, or if the decision is significant, regulated financial advice can help you model the numbers properly.
The Open Door Wealth View
The question "how much pension do I need?" is really asking: "is what I've saved enough to support the retirement I want?"
You can't answer that without knowing what the retirement you want will cost, what other income you'll have, and how long you need the money to last.
Once you know those things, the pension target becomes much clearer — and so does the gap between where you are and where you need to be.
