If you’re waiting for the perfect moment to do anything in life, there’s a risk you’ll never get around to it. And when it comes to saving and investing, you’ll pay a real price for the delay. So, it can help to know when other people have taken the plunge, and just how they’re doing, to see whether we’re on track, or if we need to get cracking. Here are the ages that are financial landmarks among AJ Bell customers.
First year of life: Junior ISA accounts are most commonly opened
The most popular time to open an AJ Bell Junior ISA (JISA) is in the first year of a child’s life. It’s a great idea for when you have a newborn, so anyone who wants to celebrate the birth can do so with a gift into the JISA that they’ll appreciate far more than a new rattle or babygrow.
However, people aren’t just using them for one-off payments. The first year of a child’s life is also the most popular time to set up a regular direct debit into the account. If this is a bit of a stretch in the expensive early years, talk to grandparents and the wider family. They may be able to make manageable monthly payments that will keep building a valuable nest egg for when they’re 18.
Age 25 to 26: The most Stocks and shares ISAs are opened
The fact that the most common age to open a Stocks and shares ISA overall is 18 is a testament to the success of the Junior ISA, and how many people have already become investors before they leave childhood.
Excluding maturing JISAs, the most popular age to open an AJ Bell Stocks and shares ISA is either 25 or 26. By this age, people will have started work and have a few years under their belt. They’ll have got to grips with their expenses and are likely to have been in a workplace pension for a few years. They don’t necessarily have vast sums of cash to put away if they’re at the start of their career, but making a start investing this early can make an enormous difference to the rest of their life. If you reach this age and investments aren’t on your radar at all, it’s worth at least investigating what it has to offer.
Age 27: When Lifetime ISAs are most frequently used for property purchases
This is the most common age to use an AJ Bell Lifetime ISA to buy a property (measured as people making penalty-free withdrawals). Given that, overall, the average age to buy a first property is 34 in the UK, there’s a decent chance the government bonus has played a vital role in helping people build the deposits they need to get onto the property ladder.
You can pay up to £4,000 a year into a LISA and the government will top it up by 25%. The LISA will eventually be replaced by a new scheme for first-time buyers, but the date of the replacement, and the size of the government top up on the new scheme haven’t been confirmed. Meanwhile, the government has emphasised anyone opening a LISA before it’s replaced will be able to pay into it and get the bonus as usual for as long as they want, so there’s still enormous benefit in taking advantage of the LISA. For anyone under the age of 27, it may be worth getting started at a younger age, while you still can.
Age 33: Most likely age to make contributions
ISA customers who are age 33 have the highest percentage making an ISA contribution than any other age group on the platform. Some people will be on higher incomes or have made investment a key priority early in life, so will have been making the most of their ISAs for years. However, others will have waited until they were on a firmer financial footing before they made a start.
If you haven’t started investing, it’s a decent time to take stock. You may have other pressing priorities, or a gap in income which means now isn’t the time for you. Otherwise, this may well be an opportunity to start your investment journey.
Age 39: Most likely to open a Lifetime ISA
This is the oldest you can be when you open a Lifetime ISA, although once it’s open, you can keep paying into it until the age of 50. It’s also the age when people are most likely to open an AJ Bell LISA. The rush at 39 might be from some people keeping their options open, just in case they want to use a LISA later.
However, there’s more to it than that, because this is the age when people are most likely to start regular payments into an AJ Bell LISA too. It’s a flexible option for retirement savings, especially for basic rate taxpayers who work for themselves or who have already taken advantage of any employer contributions to their pension. It can also be helpful for anyone who has maxed out their pension contributions. If you want to take advantage of the LISA, it’s worth doing so sooner rather than later, while you still can.
Age 56: Most likely to max out their Stocks and shares ISA
Age 56 is the most common age to max out an AJ Bell Stocks and shares ISA.** One key driver is likely to be from people who have taken the tax-free cash from a pension, who want to keep it invested tax-efficiently.
If you want investments to grow within a tax-efficient environment, then there’s no need to take the cash at 55, because a pension is a great home for your money. By leaving your cash where it is, you also give the pot chance to grow, so you can eventually withdraw a bigger sum.
However, some people have taken tax-free cash because of a lack of reassurance from the government that they’re not going to tinker with the rules. While this is a decision which should be carefully thought through, if you’re going to do this, then a Stocks and shares ISA is a sensible home for your money.
The fact this is a key time for maxing out is also partly down to the fact many people will be empty nesters. Their offspring may have moved out or started working and contributing to the household, so they may have more money to work with and more opportunities to save. It means they can concentrate on building as much for retirement as they can, as soon as they can, in a mixture of pensions and ISAs.
If you’ve reached the empty nest period, it’s worth using a pensions calculator and factoring in additional savings and investments. If you have a shortfall, you can consider whether you can afford to put more aside for the future, to make up for lost time.
Age 63: Average age of a SIPP millionaire
This is the average age of AJ Bell SIPP millionaires, but if you haven’t quite got there, there’s no need to panic. It was always bound to be the age when people have built as much as possible in their pension and start spending it down. However, it’s a handy reminder that a commitment to pension investing from an early age, sticking with it whenever possible, and investing strategically, can help build a really substantial pot for the kind of retirement you always wanted.
Age 70: Average age of an ISA millionaire
This is the most common age of AJ Bell ISA millionaires. This isn’t going to be a target for everyone, but it’s a great demonstration of the power of compounding over time. By investing consistently over the decades, ISA millionaires haven’t had to take enormous risks or trade on a daily basis. They’re evidence of how successful a ‘get rich slow’ plan can be.

The SNOWBALL currently earns income of 11k per year.
If you re-invest the dividends at a blended yield of 7% it will double every ten years.
So in twenty years, from now, your snowball should be yielding 44% per year. Better if Mr. Market allows you to re-invest at a higher yield as you can shorten the journey. You may not be a millionaire but you should be able to spend like one. GL
