How Comparing Loans Can Help

Let's say you're trying to decide whether to buy a home with a low down payment and a 30 year repayment term, or if you should make an additional $25,000 down payment and reduce the loan term to 15 years. The first loan amount is $250,000, with an interest rate of 5.50% for a term of 30 years. The second loan amount is $225,000, at a rate of 5.25%, repaid over 15 years. (This is a simplified example, and doesn't include lender charges and other costs).

  • Your monthly payment for the 30 year loan would be $1419.47; for the 15 year loan, it would be $1808.72.
  • Assuming you would take the full 30 year term to pay off the first loan, you would pay a total of $511,010.10 for P&I payments. If you used the entire 15 year term to pay off the second loan, you would pay a total of $325,570.47 in P&I payments.
  • If you utilized the full repayment term for each loan, you would pay $261,010.10 in interest for the 30 year loan and $100,570.47 for the 15 year loan.This amounts to a potential savings of $160,439.63 if you can afford the higher payments and make an additional down payment of $25,000.

The Mortgage comparison calculator assists in determining how much you can borrow to achieve an affordable payment, or if borrowing more over a longer term can meet your needs. Using different calculator tools can help you get the maximum benefits from refinancing or a new mortgage.
