This example assumes that 1000 is invested for 10 years at an annual interest rate of 5 compounded monthly. FVC6 C8 C7 C80 - C5. We have to divide interest rate with 365 to get a daily interest rate.
However in this example the interest is paid monthly.
Compounded daily the total principal and interest earned balance is 298352 after 5 years. For example lets derive the compound annual growth rate of a companys sales over 10 years. Beginning Value x 1 interest rate number of compounding periods per year years x number of compounding periods per year Future Value. For the daily compound interest formula use 365 as the parameter for Number of compounding periods per year.
