Compound interest is a concept that has the potential to significantly boost your savings and investments. Unlike simple interest, which is based solely on the principal amount of a loan, compound interest takes into account both the principal and the accumulated interest. This means that as time goes by, you earn interest not only on your initial investment but also on the interest it has already generated.
Interest rates play a crucial role in compound interest calculations. When considering investments, smart investors go beyond the nominal or coupon rate of a bond or loan and assess whether it aligns with their financial goals. By carefully analyzing interest rates, investors can make informed decisions about where to allocate their funds.
To better understand the impact of compound interest, the "Rule of 72" comes into play. The rule approximates the number of years it will take for your money to double, given a fixed interest rate. The higher the interest rate, the faster your investment will grow. For example, if you have an interest rate of 6%, your investment will double in approximately 12 years (72/6).
