You’ve no doubt heard of the snowball effect. The larger a rolling snowball becomes, the faster it grows. Even a small snowball can grow significantly without much effort, provided it’s given enough time.

Interest and investment returns can work in much the same way. When they compound, growth typically leads to further growth – even if you never add more than your initial sum.

It’s this phenomenon that Albert Einstein once described as the “eighth wonder of the world”.

Compounding means it doesn’t just matter how much you save or invest, but also when and for how long.

Read on to learn how compounding works and what it can mean for your savings and investments.

Compounding is essentially growth-on-growth

When you save or invest, your funds typically grow with either interest or returns. Compounding is when those earnings are added to your fund and go on to generate their own interest or returns.

As an example, let’s say you save £1,000 and earn 4% interest annually:

• After one year, you would earn £40 in interest, growing your pot to £1,040.
• The following year, your 4% interest is calculated based on your total £1,040 pot.
• So, without you adding any further funds, you would earn £41.60 in interest in the second year.
• In year three, you would earn £43.26, and so on.

Compounding works in much the same way when you invest. Returns can be reinvested to accelerate your gains.

As such, compounding can boost your returns when you save or invest for the long term.

The earlier you start saving or investing, the more your funds could grow

Compounding can be a powerful tool for building wealth. However, it’s more likely to have a significant impact if used over several years.

In fact, starting early could mean that saving for just 10 years generates more wealth than saving for 30. As Equifax explains, an individual who saves £100 a month with 10% interest between 30 and 60 would accumulate £217,132.11. But someone who saved at the same rate between 20 and 30, and left the funds to compound until age 60, would have a pot worth £367,090.06.

So, saving sooner could mean you don’t have to contribute as much, or for as long, to accumulate a larger pot. One of the key benefits of pension investing is the exceptionally long time horizon. Unlike many other investments, a pension is invested for much of your lifetime – not just up to your retirement date, but often throughout retirement as well. This extended timeframe allows compound interest to work to its full potential, as returns can be reinvested and continue to grow year after year.

What does compounding mean for your pension?

Generally, your pension funds are invested and grow with compound returns. So, as you build your pot, its growth is likely to accelerate.

This is why it is valuable to start saving for retirement early. Starting at age 20 could give your savings the chance to compound for over 40 years, while waiting until you’re closer to retirement could significantly limit your pot’s growth opportunities.

What’s more, compounding can mean even small contributions could have a big impact on your pot when left to grow over several years – or even decades.

Remember: it’s never too soon or too late to boost your pension contributions. If you’re considering contributing more to your pension, you can use the retirement calculators available on your Zurich app to see the benefit of this.

A pension is a long-term investment not normally accessible until 50. The fund value may fluctuate and can go down, which would have an impact on the level of pension benefits available. Past performance is not a reliable indicator of future performance.

The tax implications of pension withdrawals will be based on your individual circumstances. Thresholds, percentage rates, and tax legislation may change in subsequent Finance Acts.

The value of your investments (and any income from them) can go down as well as up and you may not get back the full amount you invested. Past performance is not a reliable indicator of future performance.

Investments should be considered over the longer term and should fit in with your overall attitude to risk and financial circumstances.
