Frequently Asked Questions
Compound interest is the interest on a loan or deposit that is calculated based on both the initial principal and the accumulated interest from previous periods. Unlike simple interest, compound interest grows exponentially over time, making it a powerful tool for building wealth.
The compound interest formula is A = P(1 + r/n)^(nt), where P is the principal amount, r is the annual interest rate (as a decimal), n is the number of times interest is compounded per year, and t is the number of years. This formula calculates the future value of an investment.
The more frequently interest is compounded, the more interest you earn. Daily compounding earns slightly more than monthly, which earns more than quarterly, and so on. However, the difference between daily and monthly compounding is usually small for typical interest rates.
