1. What is Compound Interest?

Compound interest is the interest earned on a traditional investment or deposit plus the interest earned on interest. In other words, it is interest earned on interest. This compounding effect can significantly increase the value of an investment over time, especially if the interest rate is high and the investment is planned over a long period.

2. How is Compound Interest Calculated?

The formula for calculating compound interest is:

A = P(1 + r/n)^(nt)


  • A = the future value of the investment
  • P = the initial investment or deposit
  • r = the annual interest rate (as a decimal)
  • n = the number of times the interest is compounded per year
  • t = the number of years the investment is held

For example, let’s say you invest £10,000 in a savings account with an annual interest rate of 5%, compounded monthly (n=12). After 5 years (t=5), the future value of your investment would be:

A = £10,000(1 + 0.05/12)^(12*5) = £12,762.97

This means that your initial investment of £10,000 has grown to £12,762.97 over 5 years, thanks to the power of compound interest.
