Which statements is true of compound interest?

Compound interest is the interest calculated on the initial principal and also on the accumulated interest from previous periods. This means that the interest earned in one period is added to the principal for the calculation of interest in the next period, leading to exponential growth over time. The frequency of compounding (e.g., annually, semi-annually, quarterly, or monthly) can significantly affect the total amount of interest earned. Overall, compound interest can significantly increase the value of an investment compared to simple interest, which is calculated only on the principal.
