Our Compound
Interest Calculator UK

When you’re creating your investment strategy, the goal is to maximise every financial opportunity possible. Compound growth is an essential factor in your investment strategy that can be used to strengthen your savings. The longer you save your money, the better the impact of compound growth.


However, it’s not always easy to determine how compound growth, and other factors such as inflation, will affect your savings. To make things easier, we have a compound interest calculator that can illustrate the process for you.

What is Compound Interest?

Compound interest is the growth upon the growth. As the amount in your savings pot grows, the impact that compound growth will have on your savings can be higher.

Let’s explain this in monetary terms. If you put £1,000 into an account at a rate of 10%, at the end of the first year, your investment would have grown by £100 meaning you end up with £1,100 in your account. In the second year, you could earn 10% on the total £1,100, so you could earn £110 in interest. Each year, your compound interest accumulates, and your savings should continue to grow.
