Suppose Edison receives a $21,000.00 loan to be repaid in equal installments at the end of each of the next 3 years. The interest rate is 4% compounded annually: Use the formula for the present value of an ordinary annuity to find this payment amount: PVAN=PMT1(1(1+D1)PMT=PVAN(1(1+A)1)1 In this case, PVAN equals , I equals , and N equals Using the formula for the present value of an ordinary annuity, the annual payment amount for this lasn is Because this payment is fixed over time, enter this annual payment amount in the "Payment' column of the following table for all thre yman. Each payment consists of two parts-interest and repoyment of principal, You can calculate the intereat in year 1 by multipling the loan baimce ot the beginning of the year (PVAN) by the interest rate (1). The repayment of principal is equal to the payment (pMT) mimat the intereit charpe for the year: The interest paid in year 1 is Enter the values for interest and repayment of principal for year 1 in the following table. Because the balance at the end of the first year is equal to the beginning amount minus the repayment of principal, the anding balance for year 1 . This is the beginning amount for year 2 . Enter the ending balance for year 1 and the beginning amount for year 2 in the following table. Using the same process as you did for year 1, complete the following amortization table by filing in the remaining values for years 2 and 3. Complete the following table by determining the percentage of each payment that represents interest and the percentage that represents principal for each of the three years.
