Your 40s are a critical decade for retirement planning. Here is what you should realistically have saved, what most people actually have, and how to close the gap.
Fidelity's widely cited savings milestones suggest having three times your annual salary saved by age 40. For someone earning the UK median full-time salary of roughly £35,000, that means a target of approximately £105,000. For someone on £50,000, the target is £150,000.
These numbers include everything: workplace pension, personal pension (SIPP), ISAs, and cash savings. When you add them all up, many people are closer to these targets than they realise — particularly because workplace pension pots tend to be out of sight and out of mind. The Fidelity benchmarks assume you will continue saving at a similar rate through your 40s and 50s, ultimately reaching ten times your salary by retirement.
A more grounded UK-specific range is £50,000 to £150,000 in total savings and investments by 40. This accounts for the reality that UK graduate salaries start lower than US equivalents, housing costs consume a larger share of income (especially in the South East), and auto-enrolment minimum contributions are modest. If you are within this range, you are on a reasonable track. If you are below it, the strategies later in this guide will help you accelerate.
The ONS Wealth and Assets Survey provides the most reliable picture. For the 35-44 age group, median total wealth (including property, pensions, and financial wealth) is approximately £200,000-£250,000. However, a huge portion of this is tied up in property equity for homeowners.
In terms of financial wealth — pensions, ISAs, and savings — the picture is more sobering. The median pension pot for this age group is estimated at £20,000 to £35,000, and median accessible savings and investments are around £5,000 to £15,000. Many 40 year olds have a combined pension and savings total well under £50,000.
If your total across pensions, ISAs, and savings is above £50,000, you are ahead of the median UK 40 year old. If you are above £100,000, you are in a strong position. The key insight is that averages can be misleading — a small number of high earners pull the average up significantly while the median tells a more honest story.
When people think about "how much I have saved," they typically picture their bank account balance and perhaps their ISA. They almost never think about their workplace pension. Yet for many 40 year olds, the workplace pension is their single largest financial asset outside of property.
If you have been employed and auto-enrolled since the scheme was fully rolled out, you could easily have £20,000-£50,000 in your pension without having given it much thought. And if you changed employers a few times, you might have multiple pension pots scattered across different providers. The government's pension tracing service can help you find lost pots.
Take an hour this week to log into all your pension providers and add up the total. You may be pleasantly surprised. Once you know the number, you can plan properly. Consider consolidating old pots into a single SIPP or your current employer's scheme for easier management — but check for any exit fees or valuable guaranteed benefits before transferring.
| Salary at 40 | 3x salary target | Realistic UK range | Strong position |
|---|---|---|---|
| £30,000 | £90,000 | £40,000-£80,000 | £80,000+ |
| £40,000 | £120,000 | £50,000-£110,000 | £100,000+ |
| £50,000 | £150,000 | £70,000-£140,000 | £130,000+ |
| £60,000 | £180,000 | £90,000-£170,000 | £160,000+ |
Ranges include workplace pension, personal pension (SIPP), ISAs, and accessible savings combined. Assumes 15-18 years of employment since early 20s.
Salary sacrifice reduces your gross pay before tax and National Insurance are calculated. This means you save both income tax and NICs on your pension contribution — a basic-rate taxpayer effectively pays just £68 for every £100 that goes into their pension, compared to £80 with regular relief at source. Many employers pass on their NIC savings too, making it even more efficient.
Multiple small pensions are harder to manage and often sit in default funds that may not suit your risk profile. Consolidating into a SIPP gives you full control over investment choices and fees. Check that old pots do not have valuable guaranteed annuity rates or other protected benefits before transferring.
While pensions offer tax relief, ISA withdrawals are completely tax-free. This makes ISAs ideal for bridging the gap between early retirement and pension access age (57 from 2028). Aim to build both: pension for long-term retirement, ISA for flexibility and earlier access if needed.
If your mortgage rate is low (below 4-5%), the maths often favours investing the difference rather than overpaying. A £300/month overpayment redirected to a Stocks and Shares ISA at 7% could grow to over £200,000 in 27 years. Run the numbers for your specific mortgage rate versus expected investment returns.

If you are 40 and feeling anxious about retirement, consider this: you have roughly 27 years until state pension age and about 17 years until the minimum pension access age (57 from 2028). Twenty-seven years is longer than the entire period from birth to your late twenties. It is a substantial amount of time.
The maths of compounding means that more than half of a portfolio's final value typically accumulates in the last third of the investment period. If you invest £500 per month at 7% for 27 years, you contribute £162,000 but end up with roughly £405,000. The compound growth of £243,000 exceeds your total contributions — and most of that growth happens in the final decade.
Your 40s are often your peak earning years. Salaries tend to be higher, children may become less financially dependent, and you have more financial literacy than in your 20s. Use these advantages. Even starting from a low base, aggressive saving and investing from 40 can build a meaningful retirement pot. The worst thing you can do is assume it is too late and do nothing.
