In a nutshell

You can invest in the S&P 500 in just 3 simple steps. First, find the right investment platform for you (we’ve listed the best below), then find the right ETF for the S&P 500 (we’ll cover that below too), and then buy. Simple!

Keen to invest in the future of the American economy, the S&P 500 (SPX)? You’re in the right place. Here’s a run through of the best way to invest in the S&P 500 if you’re from the UK, and we’ll cover the ins-and-outs of the S&P 500 too – just to make sure it’s the right investment for you.

What is the S&P 500?

The S&P 500 (Standard and Poor’s 500), is the largest 500 companies that are listed on stock exchanges across the US. It’s technically called a stock market index (a set group of companies that makes things easier for investors to measure, in this case, the American economy). Another popular index is the FTSE 100 (top 100 companies in the UK).

Index fund

We’ll cover the S&P 500 in much more detail below, as we’re sure you’re keen to find out how to actually invest in it.

What’s the current value of the S&P 500?

How to invest in S&P 500?

This is probably going to be easier than you think! As the S&P 500 is an index, and a very popular one, there are investment funds set up to make it super easy to invest in the S&P 500.

How to invest in S&P 500

An investment fund is simply a collection of lots of different investments (such as shares in companies), all pooled together into a single investment. Funds that track stock indexes are often called index funds.

Investment fund

And to make things even easier, investment funds can be traded on stock exchanges, just like individual company shares, making them super easy for you to buy directly. These funds are called exchange-traded funds, or ETFs.

Therefore, all you need to do is buy an ETF that tracks the S&P 500. As simple as that. Let’s run through how to do that now.

1. Pick the best ETF platform for you

First things first, you’ll need to find an investment platform that offers ETFs and index funds (exchange-traded funds). Don’t worry though, we’ve done the hard work already, and reviewed all the best ETF platforms, and here’s who comes out top:

Except for AJ Bell, with all of the best investment platforms for ETFs (above), you won’t pay any fees to open an account, or hold any investments, and you won’t even pay any commission to buy investments. How great is that? 

Note: you’ll pay all of these fees with a traditional stock broker (a company that buys and sells investments for you). Although that doesn’t mean traditional stock brokers aren’t great, they are, it’s just that they usually have fees, and are less beginner-friendly. 

One of the best stock brokers is AJ Bell¹, and they also offer a self-invested personal pension if you want to buy ETFs within a pension – we’ll cover personal pensions just below.

Investment account options

Once you’ve decided on the right investment platform for you, you’ll also need to decide which investment account you want to use. In the UK, there’s 3 options, a General Investment Account (GIA), a Stocks and Shares ISA, and a personal pension.

We’ll run through these more in-depth further down, this is just a quick summary to guide you on the right account for you.

Nuts About Money tip: if you’re unsure which account to use right now, go with a GIA, you’ll be able to open the other accounts later if you want to.

General Investment Account (GIA)

This is the standard investing account with no bells-and-whistles. You can open as many as you like, and pay in as much as you like too, but you might have to pay Capital Gains Tax on your profits in future – when you sell, and if your profits exceed £3,000 per tax year (April 6th to April 5th the following year).

General Investment Account (GIA)

Stocks and Shares ISA

A Stocks and Shares ISA is an investment account to save completely tax-free. Pretty amazing right? You can save up to £20,000 per tax year, and you’ll never, ever, pay tax on your profits or investment income.

Stocks and Shares ISA

However, you can only pay into one each tax year – so pick wisely. We’ll cover our recommendation for how to best use your ISA later on.

Personal pension

A self-invested personal pension, or SIPP, is the perfect account for saving for retirement. You’ll get a massive 25% bonus on everything you save (not a joke!), and your money will grow tax-free.

Personal pension

However, you might pay tax when you withdraw it later down the line. And you won’t be able to touch the money until you’re at least 55 (57 from 2028).

2. Find the right S&P 500 ETF for you

Okay, now you've set up your investment account with your investment platform. Let’s get onto the S&P 500 and find the right ETF for you.

On your investment platform (such as InvestEngine¹, which has absolutely no fees and is awesome for ETFs), you’ll see a huge list of lots of different ETFs – don’t panic, you’ll soon know what they all mean.

We want to find an S&P 500 index fund – and you should be able to search using the search box on most investment platforms. Once you've done this, you should see a list of all the S&P 500 ETFs, there’s quite a lot isn’t there? Let’s run through this in a bit more detail.

The types of ETFs

There’s two main types of ETFs, there’s ‘accumulating’ (Acc), and ‘distributing’ (Dist). And you’ll probably find most popular ETFs have both options.

Exchange-traded-funds (ETFs)

Accumulating is where the money the investment makes in dividends is re-invested back into the investment itself (so more of the investment bought). Dividends are payments from the business (some of its profits) to the owners of a business (e.g. the shareholders, or investors). Large, successful companies often do this regularly.

So, with an accumulating ETF of the S&P 500 – if a company pays out any dividends, the investment fund (ETF) benefits, and it uses this money to buy more shares – and as a result the value of the ETF usually increases over time. This has a compounding effect, as the fund now owns more shares overall (which can grow in value), which means you’ll make more money over time, and this snowballs over and over.

With distributing ETFs, the dividends are instead paid directly to the owners of the ETF, rather than reinvested. So, they provide an income to anyone who happens to hold a share of the investment fund. Cash will simply appear in your investment account. Distributing ETFs will grow slower over time as they’re not benefiting as much from compound interest.

ETF provider

You might also notice there’s lots of different companies offering the same S&P 500 ETF. The top ETF providers across the world are:

  • iShares (Blackrock)
  • Vanguard
  • HSBC
  • Invesco

An ETF provider (the company who has made the ETF) manages the investment, they’ll buy and sell all the individual investments (e.g. shares of a company) to put together the ETF, and manage all the day-to-day management.

For instance, they’ll buy shares of all the 500 top companies in the US to put together their S&P 500 ETF, and they’ll continually adjust the investments if companies fall out of the index, and new ones enter.

Each provider charges a fee to do this, which is an annual fee based on the percentage of the investments (for instance 0.10% of your investment in the ETF). And with ETFs, this fee is represented by the Total Expense Ratio (TER). You’ll pay this fee to hold the ETF as an investment, although it’s actually automatically deducted from the fund itself by the provider, you won’t pay out any cash.

With S&P 500 ETFs, they’re super low cost, as there’s not much management to do (as it just tracks the S&P 500 index). In fact, here’s what you’ll pay with the most popular providers:

  • iShares (Blackrock) - 0.07%
  • Vanguard - 0.07%
  • HSBC - 0.09%
  • Invesco - 0.05%

All quite similar aren’t they? Effectively they’re all the same ETF, just from different providers. So, if cost is a real issue, you could simply go for the lowest cost (Invesco).

3. Buy!

Now all that’s left to do is buy, buy, buy. 

After you’ve decided which type of S&P 500 ETF you’d like, either accumulating, or distributing (get the dividends), and which provider you’d like to use, all that’s left to do is deposit your cash to the investment platform, and buy, buy, buy. You’re now the proud owner of an S&P 500 ETF – good job!

Investing in the S&P 500 is typically seen as a great investment over the long term, as it represents the United States economy, and to an extent, the whole western world (it's used as the benchmark for other investment strategies to compare against). But that doesn’t mean the good performance is guaranteed to continue into the future.

Learn more about the S&P 500

The S&P 500 (Standard and Poor’s 500) is one of the most popular stock market indexes in the world – there’s trillions of pounds of investors money, from across the world, and of course lots of UK investors.

It tracks the largest 500 companies listed on stock exchanges in the United States – the two main ones are the New York Stock Exchange (NYSE) and the Nasdaq (National Association of Securities Dealers Automated Quotations).

An example of some of the largest companies in the US, and so part of the S&P 500, are:

  • Apple
  • Amazon
  • Alphabet (Google)
  • Citi
  • Delta Air Lines
  • Mastercard
  • Microsoft
  • Netflix

To be included in the S&P 500, the company must have:

  • A market capitalisation (company valuation) of over $12.7 billion
  • Lots of trading volume of its shares (over 250,000 shares traded in the last 6 months)
  • Be from the United States and list on a US stock exchange

There’s a few other small criteria to be included too, but these are the main ones.

Rather than each company having an equal share of the index, the index is ‘weighted’ by the size of the companies in the index, with the bigger companies having a bigger share of the index.

As part of the measurement, it uses the number of shares that are publicly traded, which means able to be bought and sold freely to the public, rather than shares held by people who work there (so not traded).

The S&P 500 is an index managed by the S&P Dow Jones Indices, and can be used as a measure of the American economy. And has seen some great returns over time (how much it’s grown). Since it began in 1928, it has returned an average of roughly 9.8% per year, so you can see why lots of investors are keen to invest in funds representing the S&P 500!

Note: the most popular ticker symbol for the S&P 500, which is a short code to identify stocks and indices, is SPX (or $SPX).

Learn more about ETFs

Investing in an exchange-traded fund is a great way to invest and build a portfolio of investments, without actually having to buy all the individual investments – you can simply buy one, or a handful of ETFs, and have a well-rounded investment portfolio, suited to your goals (such as long-term growth or providing a regular income). Making it much easier, and much cheaper too (you’ll typically save a lot in fees to buy individual investments).

They can contain a huge range of investment, such as tracking an index like the S&P 500, or they could have specific types of investments, such as only technology companies (technology stocks), or energy companies – there’s a huge range of ETF options out there, all suited to different types of investors.

Mutual funds

The alternative is a mutual fund, which is very similar (an investment that has lots of different investments within it, and looked after by a fund manager). The difference is an ETF is simply a fund you can buy on a stock exchange (such as the London Stock Exchange in the UK), and traded frequently, whereas a mutual fund you’ll buy directly or via a stock broker (like AJ Bell¹).

Investments within an investment fund

Investment funds, such as ETFs and mutual funds can hold a huge range of different investments, such as:

Stocks and shares (equities)

A share of a company, is part of the ownership of a company – you own a ‘share’ of the company. All of the shares combined total the value of the company. The share price can go up and down, and is normally affected by the business performance (e.g. sales), and the stock market in general.

Shares can be bought and sold on a stock exchange, and there’s typically a stock exchange in every country in the world, such as the New York Stock Exchange (NYSE) in the USA (plus others).

Nuts About Money tip: if you’re looking to buy individual stocks and shares, rather than ETFs and investment funds (or alongside), check out the best share dealing accounts.


A bond is essentially loaning your money to large corporations or governments in exchange for a regular income, in the form of an interest payment. Bonds are typically seen as lower risk than stocks and shares, but don’t tend to grow your money as much over time.


Investment funds can also hold property, normally commercial property, such as offices and shops that provide a regular income (rent).

Passive funds vs actively managed funds

There’s also two main types of investment funds, passive funds and actively managed funds.

Passive funds

Passive funds are investment funds, such as ETFs, that typically track a stock market index (also called stock indices), and so also often called index funds. A stock market index, like the S&P 500, or the FTSE 100 – is a set measure of a stock market, or a subset of the stock market (e.g. the top 100 companies listed on the London Stock Exchange, the FTSE 100).

As an index fund simply tracks and matches an index, there’s not much effort or investment decisions required for the fund manager. That’s how they get their name passive investment funds.

Index funds are passive

And because there’s not much involvement from the fund manager, passive funds are typically much cheaper than actively managed funds.

Actively managed funds

Actively managed funds are where the experts (fund managers) do a lot more work. They’ll put together a mix of investments to achieve a set goal of the fund, for instance, long term growth or to provide a regular income. They’ll continually monitor the investments and make changes when necessary.

And because there’s a lot more involvement from the fund manager, the fees are higher – of course they can vary depending on what the fund is.

There’s lots of actively managed funds out there, and you can find a great range with all of the recommended investment platforms above, such as InvestEngine¹.

Types of investment accounts

We’ve touched on the types of investment accounts you can use to invest in the S&P 500, but let’s run through them in a bit more detail. The right investment account can save you a lot of cash in future, and they all have different benefits and restrictions too.

General Investment Account (GIA)

A General Investment Account (GIA) is your typical investment account, there’s no benefits, but there’s also no restrictions. You can invest as much as you like, and have as many accounts as you like across all the best investment platforms.

However, you will have to pay tax on your investment profits and income, if they’re above the tax-free allowances, which runs across the tax year (April 6th to April 5th the following year).

The tax you might pay is Capital Gains Tax, Dividend Tax and Income Tax. With Capital Gains Tax, you’ve got an allowance of £12,300 in profit per tax year, before you have to pay tax, and this only applies when you sell your investments.

The amount you’ll pay is 10% if you’re a basic rate taxpayer (earn less than £50,720 per year), and 20% if you’re a higher rate taxpayer (earning more than £50,270 per year).

Stocks and Share ISA

A Stocks and Shares ISA lets you save and invest completely tax-free!

You can save up to £20,000 per tax year, which is your ISA allowance, and applies to all of your ISAs together (e.g. a Cash ISA (to save cash), or a Lifetime ISA (to save for your first home)).

However, you can only pay into one Stocks & Shares ISA per tax year – so pick wisely. A great strategy for investing can be to let the experts manage the investments within your Stocks and Shares ISA – they know what they’re doing, and you could benefit from the tax-free growth, and their expertise with the bulk of your savings. 

You can then use a GIA to make your own investments alongside the experts, and unless you have lots of cash within a GIA, you might not pay any tax anyway.

We’ve reviewed all the best expert-managed investment platforms, and the best performing Stocks and Shares ISAs to make things easy for you to find the best investment options for you.

Personal pension

A personal pension is to save and invest for your retirement, and has some awesome benefits. You’ll get a massive 25% bonus from the government on everything you pay in, how great is that?

And if you’re a higher rate (40%) or additional rate (45%) taxpayer, you’ll be able to claim some of the tax back at those rates too.

Your money will grow tax-free too, you don’t have to worry about taxes until the time comes when you want to retire and withdraw cash, at which point, the first 25% of your pension is completely tax-free, and with the rest, you might pay Income Tax on it, just like your salary now, but it depends on how much your income is, as you’ll still get the first part of your income tax-free (currently £12,570).

The downside is your money is locked away until you are at least 55 (57 from 2028).

For investing, there’s two main types of personal pension, there’s simply a ‘personal pension’, which is typically managed by experts, and they’ll grow your money over time in a sensible way (PensionBee¹ is a great option for this. Here’s our PensionBee review to learn more). 

And the other option is a self-invested personal pension (SIPP), and this is where you make your own investment decisions, that’s which investment to buy, and when to buy and sell. 

We don’t recommend these unless you know what you’re doing when it comes to investing, but check out the best pension providers to find all the best investment platform options.

Nuts About Money tip: If you want to invest in the S&P 500 within your pension, a great option is AJ Bell¹ – you’ll be able to open a SIPP and make your own investments (with low fees).

Is it safe to invest in the S&P 500?

Yep, it’s completely safe to invest in the S&P 500 via ETFs.

The ETF provider (the investment company), and the investment platform, will both be authorised by the Financial Conduct Authority (FCA). The FCA are the people who make sure your money and investments are looked after, and the company is operating in the right way – also, they’ll have been reviewed and approved to look after your money, and will also be constantly monitored.

This also means your money is protected by the Financial Services Compensation Scheme (FSCS). That’s where your money is protected up to £85,000, and compensation is provided if something happens to the investment platform or investment provider (such as going out of business).

However, as your investments are held all in your name, they can only be returned to you. They’re also typically held with large banks, such as HSBC, rather than the investment platform itself.

To check if a company is registered and authorised by the FCA, check the FCA register.

Note: FSCS protection only applies to retail investor accounts (so ‘normal’ people), rather than professional investors and companies.

This doesn’t mean the value of your investments can’t go down in value – they can.

Let’s recap

That’s all there is to investing in the S&P 500. There’s lots of index funds (exchange-traded funds) set up that track the S&P 500, making it super easy, and cheap to buy and invest in the S&P 500 (and other stock indexes, such as the FTSE 100).

As a full recap, you can invest in just 3 simple steps:

  1. Find the right investment platform
  2. Find the right type of S&P 500 investment fund
  3. Buy

And, we’ve made it even easier for you, here’s our recommended investment platforms to use (easy to use and low cost).

There we go. All the best investing in the SPX and all your future investments!
