The concept of compound interest, or 'interest on interest', is that accumulated interest is added back onto your principal sum, with future interestĬalculations being made on both the original principal and the already-accrued interest. You can include regular deposits or withdrawals within your calculation to see how they impact the future value. Simply enter your initial investment (principal amount), interest rate, compound frequency and the amount of time you're aiming to save or invest for.
