in the first step, you would make the following inputs.


present value = 0
future value = 0
number of periods = 1 year * 4 quarters per year = 4
payment amount = -20,000
interest rate % per period = 12% per year / 4 quarters per year = 3
payment is made at the beginning of each period


you would then click on fv and the calculator tells you that the future value is 86,182.72.


in the second step, you would make the following inputs.


present value = -86,182.72
future vlaue = 0
number of periods = 2 years * 4 quarters per year = 8
payment amount = -20,000
payment at beginning of period.


you would then click on ir and the calculator tells you that the interest rate % per period is 3.450286%
