The time units used for the number of payment periods, the rate of interest, and the payment amount must be the same. In other words, if you state the payment period in months, you must also express the interest rate as a monthly rate and the amount paid per month.
The rate per period is stated as a fraction of 100. For example, 10% is stated as .10. If you are calculating using monthly periods, you must also divide the rate per period by 12. Therefore, 10% per annum, for example, equates to a rate per period of .00833.
