Compound interest or anatocism is interest accumulated from a principal sum and previously accumulated interest. It is the result of reinvesting or retaining interest that would otherwise be paid out, or of the accumulation of debts from a borrower.

Future value is the value of a current sum of money or stream of cash flows at a specified date in the future, given an assumed rate of return or interest rate. It reflects the time value of money, which holds that a sum of money has different value at different points in time because it can earn a return if invested.
