Overview
Compound interest is interest accumulated from a principal sum and previously accumulated interest, resulting from reinvesting or retaining interest that would otherwise be paid out, and is contrasted with simple interest where previously accumulated interest is not added to the principal amount. It depends on the simple interest rate applied and the frequency at which the interest is compounded, making it a crucial concept in finance. Compound interest can be applied to a wide range of financial situations, from small savings accounts to large investment portfolios. Understanding compound interest is essential for making informed decisions about money management.
