How compound interest works
Compound interest allows your money to grow faster because you earn interest on both your initial investment and previously earned interest.
Formula
A = P (1 + r/n)^(nt)
Example
If you invest £1,000 with £100 monthly contributions at 5% interest for 10 years, your total value grows significantly due to compounding.
