We are asked to calculate the following variables: For a loan of $100,000, at 7 percent interest for 30 years, find the balance at the end of 4 years and 15 years. Using a financial calculator: You can solve this using a financial calculator by doing the following: Table 1: Solve for PMT = $665.30 First we need to calculate the loan payment. After plugging our values into the financial calculator we received the output payment as $665.30. Using your financial calculator, please enter the values as shown in Table 2. Table 2: Solve for PV= $95,474.19 Now that we have the loan payment amount of $665.30, we can calculate the balance at the end of four years, which is $95,474.19 Using your financial calculator, please enter the values as shown in Table 3. Table 3: Solve for PV = $74,089.59 Now that we have the loan payment amount of $665.30 we can calculate the balance at the end of 15 years, which is $74,089.59. Using the loan balances that we calculated in the first two tables, we solved that the balance at the end of 4 years was $95,474.19, and the balance at the end of 15 years was $74,089.59.
