The (more realistic) ISA millionaire

It’s a funny number, £1m.

It holds so much cultural significance for us we made a TV show out of it.

Maybe that’s because it’s the smallest amount of money you need to be rich in our collective eyes. After all, it’s the first amount we add ‘-aire’ to. Thousandaires aren’t all that impressive in the UK, but millionaires, that’s a different story.

So maybe that’s why it stands as a financial goal for many people. A symbol of what hard work can get you and a level at which you can feel you’ve done well.

But what if you could get there, not by being a business tycoon, but by being a steady and ardent saver? 

How to become an ISA millionaire

Normally when it comes to describing the maths to hit the mythical million in your Individual Savings Account (ISA), the eye-rolling starts.

The figures the financial industry trot out adopt some variant of “Just save the maximum £20,000 into your ISA from the age of 18 and you’ll get there.” 

Nauseating and tone deaf for the most part.

So, is it actually possible to become an ISA millionaire without generating crazy returns or having huge wads of cash to start off with?

Yes and no, is the honest answer.

We’ve run the numbers and the maths stacks up but there are a lot of assumptions we have to make to get to the magical million. 

We’ve put them below. You might think some are well within your grasp and others seem out of touch with what the average Briton could realistically earn or afford to put into their ISA. 

And you’re probably right to scoff at certain aspects but the maths doesn’t lie. Ultimately, it won’t be achievable for everyone because our earning potential and ability to save can swing wildly throughout our lives.

But remember, that lovely round £1,000,000 figure is actually a fairly arbitrary number. 

Using it as a goal works because we tend to see it as a significant milestone. But really the message to take away from all of this is how consistent investing and using time to compound quite a reasonable level of return can amplify your financial position.

That said, let’s look at the numbers. The salary figures below aren’t the most important part, as we’re looking at what you could invest, but we’ve used them to give an idea of our potential savings rising as our earnings do too.

ISA millionaire strategy

• You start off earning £25,000 at 25 years old, investing £2,500 each year until you’re 30, achieving 5% returns, compounded once per year.
  

• At 30 you start to earn £30,000, just short of the national average. In your 30s you get yearly pay rises of 3%, just ahead of the Bank of England’s target inflation rate of 2%, and invest £5,000 each year.
  

• At 40, your pay goes up to £45,000. You keep getting yearly pay rises of 3% and put away £10,000 each year in your 40s.
  

• At 50, you start to earn £65,000, continue getting 3% pay rises and save £20,000 each year in your 50s.
  

• At 60, you start to earn £90,000 and receive 3% yearly pay rises until you retire at 65. You save £20,000 each year from 60 to 65.
  

• Taking into account a £3 monthly ISA fee, by retirement age, your total contributions of £461,060 have been able to snowball into a sum of £1,026,766.

Who wants to be an ISA millionaire? Well... everyone.

‍
Initially, a few questions come to mind.

Where am I living during all of this? What about my pension, shouldn’t I be putting money into it too? How do I choose between an ISA and a SIPP (self-invested personal pension)? Should I really be stock trading in line with those earnings at those ages?

And they are completely fair challenges.

A £90k salary would also put you among the country’s top earners, which won’t be where most of us end up. But the figures at the lower end might actually look quite reasonable, using the UK’s average earnings figures as a yardstick.

So possible, yes. Probable, less so. That doesn’t mean it can’t remain a goal. And maybe seeing it written down in black and white can serve as a bit of scaffolding. 

It might help you structure how you think about hitting your financial goals, no matter how many zeros they have on the end of them.

The focus should really be the bigger picture here. Just look at what a consistent approach to investing over the long term, and letting time do the work, can achieve.

If you’re able to start earlier, or save more than £208.33 per month in your 20s, or £416.67 in your 30s it can really shave off the sums you’d have to save later down the line. That’s thanks to the time you’ll have on hand to compound your money.

Stocks and shares ISA dividends

So while we’re talking compounding, let’s talk dividends.

They’re the bedrock of all long-term stock market investing and, if you’re aiming to become an ISA millionaire, they’ll likely be a key part of your journey.

So, let’s start with “what is a dividend?”

It’s a regular payout from a company to its shareholders as a thank you for being there, and also to keep investors sweet and invested.

The payment amount depends on the earnings that company makes.

So, rather than getting doe-eyed at headline dividend percentages, we need to make sure those earnings are strong and consistent enough to keep our dividends flowing.

In short, a company’s ability to pay a dividend matters more than the dividend itself.

Start by looking past the top line figure, to the dividend cover.

Is the firm actually going to be able to pay you that figure, and sustainably, or are you being hypnotised by the big number when the rest of the business is collapsing?

With a lot of dividends starting to reappear after hibernating during lockdown, it's also important to keep tabs on a company's share price.

Income payments might resume but if the share price stumbles across the bottom of the page it's not going to make your portfolio any happier.

Back to dividend cover. You'll likely see it expressed as holding ‘2x’ or ‘3x’ the level needed to meet the next dividend.

Looking at the levels of cash on the balance sheet can help sort the leaders from the basket cases too.

Quite often the top dividend stocks of the moment stop being so good after that.

That 5% we’re aiming for can be made up of growing dividends and a rising share price too.

So remember to factor both into your strategy.

Why should I use my ISA for income?

Something the growth side of the ISA millionaire story can miss is the benefit of using an ISA after the accumulation phase is complete - whether you’ve hit the £1m mark or not.

We normally associate taking an income from our investments with retirement, and tapping into that pension pot.

While those long-term savings are clearly geared towards letting you do just that (currently you can’t access your pension until you’re 55) planning to take an income from your investments doesn’t have to be confined to your retirement savings. 

Using an ISA has the benefit of not requiring you to pay tax when you take your money out of it - something you have to consider when you take money from your pension later in life. 

Of course there are things like company contributions and tax relief you get with a pension so they’re definitely not to be overlooked.

But what if your plan is to wind down in work before the age of 55, or before the state pension kicks in around the age of 68?

You might have plans to go part-time or just take on the projects you want. Income from your ISA could help supplement your pay until you can access your pension savings.

So, given that growing those dividends and aiming for that 5% compound growth (or higher) is the goal, what assets are out there to help?

ISA millionaire portfolio

It’s up to you what to put in it but there are US and UK stocks, and investment trusts, with a strong commitment to growing their dividends as well as aiming for capital growth at the same time.

The long-term average dividend yield of the UK stock market sits at around 4%. If you find consistency around or above that level but not so far as to make you wonder how sustainable it is, you’re on the right track.

Examples in the UK might be some consumer staples, big pharma and even the likes of British American Tobacco (BAT). 

You can also have a look at the so-called dividend aristocrats who prize maintaining their dividends over almost everything.

Thankfully, there are exchange-traded funds (ETFs) that keep tabs on these types of stocks for you.

Examples here include the SPDR S&P US Dividend Aristocrats ETF, which tracks the 60 highest-yielding US stocks with 25 consecutive years of growing dividends, and the SPDR S&P UK Dividend Aristocrats ETF, which follows the performance of the best UK dividend stocks.

And have a look at the investment trusts in the dividend hero brigade. These are portfolios with fund managers at the helm, searching the globe for growth and income opportunities.

A key highlight of trusts is their ability to put 15% of their income to one side in a year, so they can bolster payments to investors when dividend income suddenly becomes hard to find.

You might even want to think about looking beyond the obvious dividend-payers to the alternative sources of income on the stock market, for diversification.

It’s important to say that simply investing in these assets isn’t a passport to the ISA millionaire club. There’s risk involved in all types of investing, and outcomes are never guaranteed. 

Before you get into any of it, have a look at our guide on how to trade stocks for beginners.

What is an ISA?

If all of this intrigues you and you haven’t quite got to grips with ISAs just yet, here’s a quick guide.

An ISA is an account you can use to put money away and, with a stocks and shares ISA, invest it for your future.

You can currently contribute up to £20,000 during the 2021/22 tax year (from April to April).

You can put money in and take it out when you need to but it’s important to remember that if you’re investing you should take a long-term view.

A key thing to understand from the get-go is that the ISA is just the outer shell for you to fill with your investments - it’s not an investment itself.

That’s why you’ll often hear it described as a ‘wrapper’ - you get to decide on the filling.

And the reason you’ll also hear that one-upped to ‘tax wrapper’ is because, when you put your investments in an ISA, you don’t have to pay tax on any capital gains your investments achieve.

You can also only open one stocks and shares ISA account with one provider each year. 

If you find another company whose fees are lower, or whose platform just suits you better, you can either transfer your current one to them, or wait until the new tax year to open a brand new ISA with them. Find out more on how to transfer an ISA.
