The following compounding periods can be selected:

360, 364, 365 or 366 times per year - weekly
52 times per year - bi-weekly (every two weeks)
26 times per year - semi-monthly (twice a month)
24 times per year - monthly

where: FV = Future value R = Nominal interest rate per year (as a decimal, not in percentage) T = Time period in years I = Interest amount N = Number of compounding periods in one yearPMT = Periodic payment amount, paid at the end of each payment period Note: r = interest rate per period For example, if you borrow $1000 for 2 years at 12% interest compounded quarterly, you must divide the annual interest rate by 4 to obtain the interest rate per period (r = R / N = 12 / 4 = 3%). |
