Suppose Rajiv receives a $27,000.00 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: PVANPMT=PMTI(1(1+I)N1)=PVAN(1(1+I)N1)I 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 loan is You can use the formula for the present value of an ordinary annuity to find this payment amount: PVAN$100,000PMT=PMTI(1(1+I)N1)=PMT0.06(1(1+0.06)51)=$23,739.64 Each payment of $23,739.64 consists of two parts-interest and repayment of principal. An amortization schedule shows this breakdown over time. You can calculate the interest in each period by multiplying the loan balance at the beginning of the year by the interest rate: InterestinYear1=LoanBalanceattheBeginningofYear1InterestRate=$100,0000.06=$6,000 What is an amortization schedule? A table that shows how the loan payment changes each period. A table that shows how the loan will be repaid over time. A loan that requires regular fixed payments over the life of the loan. A loan that gets paid off upon the death of the borrower. An amortized loan is a loan that is to be repaid in equal amounts on a monthly, quarterly, or annual basis. Many loans such as car loans, home mortgage loans, and student loans are paid off over time in regular, fixed installments; these loans are a great real-world application of compound interest. For example, suppose a homeowner borrows $100,000 on a mortgage loan, and the loan is to be repaid in 5 equal payments at the end of each of the next 5 years. If the lender charges 6% on the balance at the beginning of each year, what is the payment the homeowner must make each year? Given what you know about present value (PV) and future value (FV), you can deduce that the sum of the PV of each payment the homeowner makes must add up to $100,000 : $100,000=1.061PMT+1.062PMT+1.063PMT+1.064PMT+1.065PMT=t=151.06tPMT Notice that the interest portion is relatively high in the first year, but then it declines as the loan balance decreases. The repayment of principal is equal to the payment minus the interest charge for the year: You can perform similar calculations to fill in the remainder of the amortization schedule. Because this payment is fixed over time, enter this annual payment amount in the "Payment" column of the following table for all three years. Each payment consists of two parts-interest and repayment of principal. You can calculate the interest in year 1 by multiplying the loan balance at the beginning of the year (PVAN) by the interest rate (I). The repayment of principal is equal to the payment (PMT) minus the interest charge 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 ending balance for year 1 is . 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. 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. 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. Step 3: Practice: Amortization Schedule Now it's time for you to practice what you've learned. Suppose Simone receives a $40,000.00 loan to be repaid in equal installments at the end of each of the next 3 years. The interest rate is 8% compounded annually. Suppose Simone receives a $40,000.00 loan to be repaid in equal installments at the end of each of the next 3 years. The interest rate is 8% compounded annually. Complete the following amortization schedule by calculating the payment, interest, repayment of principal, and ending balance for each year. 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
