Let's get right to the question above. A mortgage loan is made up on principal payments and interest payments. From the first payment you make the interest payment goes down and the principal payment goes up. How much goes to each is a function of the length of the loan. In the case of the 30 year loan the interest payment is higher from the start and it takes 14 years, 3 months at current interest rates for the interest to go far enough down and the principal payment rise high enough for the two to be even.

After that point the principal payment grows more every payment until the loan is over.

In a 15 year loan the first payment has the principal greater than the interest portion of the payment and continues to grow until the loan is paid off. The first payment for the 15 year is 59.2% toward the principal pay down and 41.8% toward interest. The 30 year fixed is almost the opposite on the first payment. 73% of the first payment goes to interest and only 27% goes to principal. There is the reason why it takes 30 years, under a simple interest scenario, to pay off the loan.

Does a 15 year loan seem better than a 30 year at this point?
