Calculate more precisely

In order to obtain the periodic amortization payments ( as ) of any loan with fractional interest payments you have to work with the effective rate of interest per time unit ( i(m) ), because of that, if you do not enter this rate of interest, it is necessary to do the following conversion: Once calculated the effective rate of interest per time unit ( i(m) ), you have to know that in this kind of operation there is only one principal repayment( Am ) per year, which is in the last amortization payments of each year ( am ), so the rest of the periodic amortization payments ( a1...am-1 ) only pay interest ( Is ). That is why the periodic amortization payments are calculated as follows:

• The last amortization payments of each year ( am ), if the loan has annual coupon that is the only amortization payments, is calculated with the following formula: • The rest of the periodic amortization payments ( a1...am-1 ) of each year is calculated with the following formula:
