When to save, when to invest and how to know the difference

By Juliet Schooling Latter on 29 April 2026 in Basics

Saving and investing are often mistakenly regarded as being the same, but the reality is that they have very distinct roles to play in your finances.

Here we take a look at the differences, when each is most appropriate, their various pros and cons and how much you should be putting away.

What is saving?

Saving is most suitable for short and medium-term goals. This includes putting money aside for holidays, a new car or even a house deposit. It’s also useful for emergencies. Everyone needs a so-called rainy-day fund of cash for unexpected costs, such as replacing the boiler.

What is investing?

Investing aims to grow the value of your money over the long term. This is usually regarded as being periods of at least five years. A prime example is building up a substantial retirement pot that grows faster than inflation to support you in later life.

Pros and cons

There are positives and negatives to both saving and investing. Savings accounts are simple to understand and provide easy access to your money. Your savings are protected up to £120,000 by the Financial Services Compensation Scheme should your UK-authorised provider go out of business. However, interest rates are generally low. Some accounts offer less than inflation, meaning your money is effectively losing purchasing power.

The world of investing offers the prospect of higher total returns, in terms of both capital growth and income generation. However, it can be difficult to choose the right asset classes, and there’s no guarantee that you’ll enjoy decent returns. In fact, you could potentially lose everything.

The right balance

Finding the right balance between saving and investing can feel tricky, especially right now, when everyday costs are high and things like energy bills and rent can shift so quickly. So first, it’s important to say this clearly: there isn’t a “perfect” formula that works for everyone all the time.

A helpful starting point is to think in terms of three buckets: what you need today, what you want and what you’re building for your future. Many people have heard of the 50-30-20 rule, where 50% of income goes to essentials, 30% to lifestyle spending and 20% to saving and investing. It’s a useful guide, but not a strict rule.

For beginners especially, the priority is often simply creating breathing room. That might mean focusing first on building a small emergency fund in an easy-access savings account, so unexpected costs don’t knock you off track. Even small, consistent amounts can build real security over time. Remember, the balance between the two can shift depending on your income, your responsibilities, and what life is asking of you right now.

Factors to consider

Before putting any money aside, you need to look at your debts. Do you have existing loans or credit card debts? Are you paying interest to anyone else on previous borrowings? Unless you are being offered an unbelievably high interest rate, the chances are you’ll be better off clearing your debts before starting to save. The general exception to this rule is a mortgage.

You must also consider inflation. This is a measure of how much prices of goods and services have increased over the past year, expressed as a percentage. Let’s use the example of an item priced at £100. If inflation is running at 10%, then it will have risen by £10 to £110 over the course of that year.

If inflation is rising by more than the rate of interest being paid on your cash savings, then the value of your money is being eroded, and its purchasing power is lower.

Here we take a look at how to save and invest.

How to save

The starting point should always be cash savings. Ensure you have money set aside for emergencies at the very least. This will give you some short-term security. Aim to have enough set aside to cover your bills for at least three months. This will help protect you from periods out of work through illness.

Savings accounts are pretty straightforward. You earn a set amount of interest while your money is in the account. Providers will be upfront about how much they will pay. However, it’s worth paying attention to the small print. For example, will you only receive that interest rate if you keep your money in for a set amount of time?

You may opt for several savings accounts. You will need one that provides easy access for emergencies, but you may opt for another that pays a higher rate if you lock money away for a year.

The key facts to consider

• Is the provider UK-authorised?
• How much interest will you receive?
• What access will you have to the money?
• Are there restrictions?

Cash Individual Savings Accounts (ISAs) are worth considering because all interest earned is tax-free. Currently, you can save up to £20,000 in a cash ISA during any tax year. However, this is due to be reduced to £12,000 a year from April 2027 for those under 65 to encourage more people to open a Stocks and Shares ISA.

How to invest

Once you have short-term savings in place, you can consider investing. The good news is that it’s easy to get started and not that expensive. As little as £20 a month can give you access to investment funds run by experienced managers that invest in a variety of asset classes and international companies.

It’s important, though, to go into investing with the right expectations. Volatility isn’t an exception in markets, it’s a normal, ongoing feature of them. Prices will rise and fall, sometimes sharply, and that can feel uncomfortable at first. A key part of becoming a confident investor is learning to accept that uncertainty is built into the process, rather than something to avoid. This is exactly where understanding your own mindset becomes so valuable.

Our Psychology of Money course explores how emotions, habits, and beliefs shape the way we respond to financial ups and downs, and why staying consistent matters more than reacting to every movement.

Investing is also about clarity. You need to understand what you’re investing for, how long you’re willing to leave your money invested, how much you can realistically contribute, and what level of return you’re aiming for. These answers will naturally look different depending on your goals, whether that’s building a pension pot, saving towards a home, or creating an additional income stream for the future.

Your attitude to risk is another key part of this. It’s worth asking yourself how you respond to uncertainty: can you stay steady when markets fall, or do short-term dips feel overwhelming? There’s no “right” answer here, but there is real value in being honest with yourself. No investment is completely risk-free, but risk can be managed (not eliminated) through time, diversification, and structure.

If you want to go deeper into how investing risk actually works in practice, our Demystifying Investments course breaks this down in a simple, practical way so you can make decisions with more confidence and less guesswork.

Three funds to consider

The right fund depends on your goals, time horizon, and attitude to risk. The good news is there are plenty of options to choose from.

Diversified multi-asset funds, which spread your money across different asset classes, can be a simple way to get broad market exposure in a single investment. For many beginners, they can work well as a straightforward “one-stop shop” or as the core of a wider portfolio.

The first suggestion is Ninety One Diversified Income. This is in the IA Mixed Investment 0-35% shares sector. This means equity exposure is capped at 35%. It aims to provide investors with an attractive, sustainable income stream with a target yield of 4% per annum, distributed monthly.

Another option is M&G Income and Growth, which sits in the IA Mixed Investment 20-60% shares sector. This means equity exposure is limited to 20-40%. This is a multi-asset portfolio, managed by Steven Andrew and Stefano Amato, that invests directly in individual stocks and bonds, as well as property funds.

Our third suggestion is IFSL Wise Multi-Asset Income. This fund is in the IA Mixed Investment 40-85% shares sector, meaning it’s still diversified but can have substantial equity exposure. The portfolio, which aims to provide long-term income and capital growth, has a value focus, meaning it prefers out-of-favour areas of the market.
