Your mid‑40s and mid‑50s could well be your peak earning years and, in theory, are a great time to set yourself up for the future.

But this period can also be one of the toughest, bringing the pressure of supporting ageing parents while still helping dependent children. One in six so-called sandwich carers are struggling financially, according to Office for National Statistics data.

It can be tempting to use your savings to help others but you need to maintain your own financial buffer and ensure you have a robust plan for retirement.

Rosie Hooper from the wealth management firm Quilter Cheviot said: “While supporting your family is important, it is vital you do not sacrifice your own long-term financial security. This means regularly contributing to your pension, keeping your emergency fund topped up and covering your essential bills before offering help to others. Think of it as putting on your own oxygen mask first.”

Midlife is a good time to tuck away money, but make sure you can get at some in an emergency. Hooper said: “Aim to have three to six months’ worth of essential expenditure in an easy access account to act as a financial buffer, for things like when your car needs repairs.”

The top rates on easy access accounts (without introductory bonuses) include 4.11 per cent from Spring Savings and 4.09 per cent from Charter Savings Bank.

Step two: the Isas

Once you have set aside your emergency fund cushion, you can make the most of your £20,000 annual Isa allowance and start investing, if you haven’t already.

If you want to stick with cash, Atom Bank has an easy access Isa that pays 4.25 per cent interest and Charter Savings Bank has one paying 4.09 per cent. Be aware that the amount you will be able to put in cash Isas will be restricted to £12,000 from April 2027 for everyone under 65, although the total for cash and stocks and shares Isas will stay at £20,000.

While cash is the right home for your emergency fund, anything beyond that risks being eroded by inflation if interest rates are low. You can expect to make more from a well diversified stocks and shares Isa, where gains are sheltered from capital gains tax and dividend tax.

Alice Haine from the investment platform Bestinvest said: “Some savers may want to maximise their cash Isa entitlement before the new rules kick in. Yet investments, particularly stocks, have historically delivered higher real returns than cash over longer periods, albeit with some volatility in the short term.”

If you had invested £10,000 in a fund that tracks the MSCI World index of 1,300 large companies in 23 developed countries, you would have £37,287 today, according to the wealth manager Rathbones. If you had left the £10,000 in cash savings accounts earning average interest rates it would be worth £11,934.

Alex Race from Rathbones said: “This shows that holding too much in cash over the long term can mean missing out on the inflation-beating growth that a well diversified investment portfolio can deliver.”

Step three: work out how much you need

Once you have investments, keep an eye on them. Race said: “Much like a car, your portfolio needs a thorough check-up from time to time to ensure it stays aligned with your financial goals, the time you have to invest and your risk appetite.”

If you are savings for retirement, then what you want from your portfolio will depend on how much you have saved overall and the kind of lifestyle you are aiming for.

As a guide, the industry body Pensions UK estimates that a couple seeking a moderate standard of living in retirement would need a post-tax income of £43,900 a year between them. Someone living alone would need £31,700. This would cover all essentials plus an overseas holiday once a year, a take-away once a week and eating out a couple of times a month.

For a comfortable standard of living a two-person household would need an annual income of £60,600 after tax and a single person £43,900. This would cover extra-long weekends and day trips away in the UK and more spending on eating out and social activities.

The minimum standard of living would require £13,400 a year for a single person — just above the £12,548 that a full new state pension will be worth from April — and £21,600 for a couple. All figures assume you will have no housing costs.

Pensions UK said that securing a comfortable lifestyle through an annuity (an insurance product that allows you to buy a set income) would require a couple to have a savings pot of between £300,000 and £460,000 each on top of these state pension. A person living alone would need a pot of £540,000 to £800,000.

The alternative to buying an annuity is income drawdown, where you keep your pension pot invested but take an income from it. You could also choose a combination of the two.

Experts generally say that you can take 4-5 per cent from your pot each year and it should last 30 years. The more you take, the quicker your pot will diminish. You could take more one year and less the next if circumstances allow.

Philip Gillett from Chester Rose Financial Planning said: “A pension pot of £200,000, for example, might generate an income of £8,000 to £10,000 a year in retirement based on withdrawals of 4 to 5 per cent.”

Step four: max out your pension

As midlife is likely to be your peak earning time, you may have more flexibility to increase your contributions in what could be the most powerful pension-building window of your life.

Camilla Esmund from the fund platform Interactive Investor said: “Pensions remain one of the most tax-efficient ways to save, especially if you pay higher rates of tax.”

Pension contributions get tax relief at your income tax rate. It means that higher rate taxpayers effectively get a 40p top-up from HM Revenue & Customs for every 60p that they contribute. Additional rate tax payers get a 45p top-up.

Thanks to the power of compounding — earning interest on your interest as well as your initial investment — even a decade of additional contributions at this stage could make a meaningful difference to your final pot. You can access a pension from 55 (57 from April 2028).

A good strategy is to maximise your workplace pension if you can. Employers have to pay at least 3 per cent of your qualifying earnings into your pension, as long as you pay at least 5 per cent. Some workplaces offer to match higher contributions, so it could be worth paying in more to benefit from the extra boost.

See if you can take advantage of salary sacrifice, where you give up part of your gross salary to go into your pensions, saving you income tax at source and also national insurance for you and your employer. The chancellor, Rachel Reeves is to cap this relief from 2029 so make the most of it while you can.

If you are not on track for a the full state pension, perhaps because of years given over to childcare or caring for an elderly parent, see if you can to make voluntary national insurance contributions to fill the gaps in your record.

If you have left saving for retirement until later in life, you need to act now.

Someone aged 40 earning £45,000 who had 10 per cent added to their pension until state pension age of 68 could amass a pot worth about £340,300, according to Quilter Cheviot. This assumed growth of 5 per cent a year, wage growth of 3 per cent, and investment-related fees of 0.7 per cent.

If they upped their annual contribution to 15 per cent, their pension pot could be worth about £510,500.

Step five: plan for expensive children

These days the Bank of Mum and Dad can expect to be tapped up for big expenses such as university costs or a house deposit.

Hooper said: “The important thing to determine is what you can afford to contribute. This may be different from what you feel you should, or would like to, contribute.”

Don’t rush in to paying off your child’s student loan, for example. Look at the interest rate they will be paying, and whether they can afford it. Hooper said: “It is important to determine the likelihood of a student loan being paid off in the longer term before committing, because the money may be better used elsewhere.”

While supporting a child financially can feel instinctive, it’s crucial that supporting others does not come at the expense of your own long-term financial security. It is better for them if you can support yourself in later life.

Gillett said: “It’s common to prioritise your children’s needs over your own but without a plan these impulses can quietly erode the financial foundation you will need in retirement.”

Step six: make a plan with your parents

Don’t shy away from talking about things such as care, death and inheritance with your parents. It’s far better to know how they feel and to work out a plan before any crisis hits.

Carve out time to chat about how care could be paid for, and make sure that they have a will to ensure that their assets are passed on according to their wishes.

Gillett said: “These conversations are difficult, which is precisely why most families never have them.

“Talking openly about money, inheritance and what a parent actually wants to happen requires a kind of courage that doesn’t come naturally around the dinner table. But the cost of not talking — in missed planning opportunities, family disagreements, and unnecessary taxes — can be enormous.”

Everything you need to know about the seven-year inheritance tax rule

Don’t delay in arranging a lasting power of attorney. This will enable you to carry out your parents’ wishes should they lose the capacity to act for themselves.

Gillett said: “Lasting power of attorney, planned lifetime giving, up-to-date wills and trust arrangements can all make a profound difference to how wealth moves through a family and how much of it survives the journey.

“Each individual can give away up to £3,000 a year free of inheritance tax, with larger gifts also possible. These are not complicated strategies. They simply require someone to start the conversation.”
