What is compound interest?

Compound interest is when the interest is added to the principal amount instead of being paid out, so the interest generated in the next period will be on the principal amount plus any accumulated interest.

The accumulative effect can be very powerful over a number of years!

For example

If you have £1,000 and 5% annual interest, and you reinvest the interest every year, after 3 years you will have £1,157.63. That’s a 15.7% increase!
