See how your savings and investments grow over time with compound interest. Plan your financial future with confidence.
Compound interest is the interest calculated on both the initial principal and the accumulated interest from previous periods. Often called "interest on interest," compounding is one of the most powerful forces in personal finance and investing. Albert Einstein reportedly called it the "eighth wonder of the world." The frequency of compounding (daily, monthly, quarterly, or annually) significantly affects how quickly your money grows. The longer your investment horizon, the more dramatic the compounding effect becomes, which is why starting to save and invest early is one of the most important financial decisions you can make.
Using our Compound Interest Calculator is easy. Enter your initial investment amount, the monthly contribution you plan to add, the expected annual rate of return, and the number of years you plan to invest. Select how frequently the interest compounds from the dropdown menu. The calculator instantly shows your future value, total contributions made, and total interest earned. You can adjust any parameter to explore different savings scenarios. For example, see how increasing your monthly contributions or extending your investment timeline dramatically impacts your final balance thanks to the power of compounding.
