Beth yw a Compound Interest Calculator?

A Compound Interest Calculator shows how your money grows when interest is earned not just on your initial investment, but also on the interest that accumulates over time. This 'interest on interest' effect is the foundation of long-term wealth building and why starting to invest early makes such a dramatic difference.

Sut i use

Enter your initial investment amount, expected annual interest rate (historical stock market average is about 10%, conservative estimate is 6-7%), the number of years you plan to invest, and how often interest compounds (monthly is most common). The calculator shows your future value, total interest earned, and growth percentage.
