Saving vs investing: which is right for you?

Saving vs investing – what’s the difference?

The main difference between saving and investing is risk. Put your money in a savings account and it's pretty safe, there's minimal risk that you'll lose it. If you choose to invest your money, you’re taking the risk that the investment could fall in value, losing you money. 

So, why does anyone invest? Well, in return for that increased risk you usually get a bigger reward than is available in a traditional savings account. In 2025 the average interest rate paid on cash savings was 3.5%, according to MoneyFacts. In contrast, the FTSE 250 – which tracks the performance of the UK’s 250 biggest companies you can invest in – grew by 8.2%.

That means £1,000 in the average savings account would have grown to £1,035. While £1,000 invested to track the performance of the FTSE 250 would have grown to £1,082.

Why should I save?

Getting into a habit of saving can make a huge difference to your future. Building up pots of money you can fall back on helps you build financial resilience which can lead to less worry and a happier life.

It’s a good idea to have at least three to six months’ worth of living expenses, That includes your essentials like rent, food and bills, set aside so you have a financial backup if anything unexpected happens.

When you first start saving it's best to have money you can access quickly if you need it. An instant-access savings account is a great choice although you probably won't get a great rate of interest. 

Once you have your emergency fund you may have other goals you want to save for like a big purchase or a holiday. If it’s money you're going to want to spend in the next five years, then a savings account is the best place to put it. That’s because there's no risk of your money falling in value and you’ll be able to access it easily when you want it.

Are savings accounts worth it?

Yes, savings accounts are worth it. If the alternative is keeping your money under the mattress or in a piggy bank, then any savings account is a better option. That’s because savings accounts pay you interest, you get a percentage of your balance regularly added to your account. It's also much safer to have your money saved in an account rather than keeping it at home.

Savings accounts usually pay more interest than current accounts too. Putting your savings into a separate account ringfences it from your everyday money, so you're less likely to spend it.

To make sure your savings account is worth it, shop around for one that pays the most interest and suits your needs. This will help your savings grow even faster.

Why should I invest?

The main reason to invest is that your money can work harder for you. Investments can grow your money in two ways. Firstly, capital growth – where the price of the investment you’ve bought rises so you can sell it for more than you originally paid. Secondly, income – some investments will pay you an income while you hold them.

Over time investments tend to provide a larger return than cash. This means you can build a bigger savings pot and it also helps your savings outpace inflation.

Inflation is the rate at which the price of everyday things is rising. You need your savings to grow faster than inflation just to keep up with the rising cost of living. Many cash savings accounts don’t pay enough interest to beat inflation, whereas investments usually grow faster than it.

Many people invest for long-term goals such as retirement, but it’s also a great way to steadily build your wealth and provide yourself and your family with greater financial security.

Is investing worth it?

Investments tend to grow faster than the interest you can earn on a cash savings account. Stock markets do fall and take the value of investments with them, but they rise as well. 

As long as you're in it for the long term, five years is generally seen as the minimum, your investments should ride out the bumps in the stock market and provide you with more growth than you’d get with cash.

Let’s say you invested £10,000 30 years ago and put £10,000 in a cash savings account at the same time and haven’t touched either since. 

The global stock market – as measured by the MSCI All Country World Index, a benchmark that tracks stock markets across the world – has risen by 1,091% over that time. That means your investments would have been worth £119,182 at the start of 2026.

In contrast, assuming you got an average interest rate on your savings – as measured by the Morningstar UK Savings 2,500, a benchmark that tracks UK savings rates – your balance at the start of the year would have been £14,797.

With a difference of over £100,000, history suggests that over the long-term investments will grow significantly more than cash savings.

How much money should I keep in savings vs investing?

The simple way to work this out is always to start with your cash savings, make sure you have everything covered there and then the excess is what you can invest.

Before you start investing, deal with any debts you have. The interest you're paying on your debts could be far higher than you could earn in savings accounts or investing. So, it makes sense to clear high-interest debts – such as credit cards or loans – before you start investing.

Next, make sure you have that emergency fund we mentioned earlier. That’s money you can access easily for an unexpected cost or if your income suddenly drops. A sensible amount is enough to cover three to six months’ core living expenses. So, if your monthly bills are £1,500, you’d need between £4,500 and £9,000.

Then think about your savings goals. Short-term savings – anything you’ll need in the next five years – are best kept in cash so they aren’t affected by a blip in the stock market just when you need it.

After your cash savings are sorted, investing is the next step for your long-term savings. How much money you keep in investments depends on what you have left after you’ve met your short-term savings goals.

Should I save or invest?

So, is it better to save money or invest? The smartest move is to do both. Save for the short term – up to five years – and invest for your long-term goals. By saving and investing you get the security that cash savings offer with the possibility of more growth that investing brings.
