Your interest rate (6%) is the annual rate on the loan. To calculate amortization, you will convert the annual interest rate into a monthly rate. The term of the loan is 360 months (30 years). Since amortization is a monthly calculation in this example, the term is stated in months, not years. Your monthly payment is $599.95. The dollar amount of the payment stays constant.
Many teenagers can eat 1 to 3 servings per week without gaining too much weight. Remember too much sweets and desserts will also effect the amount of skin problems your teenager has, like pimples.
