Compound interest is one of the most powerful concepts in personal finance. Unlike simple interest, which is calculated only on the initial principal, compound interest is calculated on the principal plus all previously accumulated interest. This "interest on interest" effect causes your money to grow exponentially over time. Our compound interest calculator helps you visualize how regular contributions combined with compound growth can significantly accelerate your savings. Whether you are saving for retirement, a down payment, or any long-term goal, understanding compound interest is essential for making informed financial decisions.
