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.

The Institute of Medicine recommends that teenage boys consume at least 130 grams of carbohydrates each day and that 45 to 65 percent of their total calories come from carbs. So, teen boys should get 225 to 325 grams of carbs as part of a 2,000-calorie diet, 293 to 423 grams for a 2,600-calorie diet and 360 to 520 grams of carbs per day if they are eating a 3,200-calorie diet.
