Home mortgage? Car? Boat? Thinking about borrowing money? Enter the amount of money you're thinking of borrowing, the interest rate, and the number of monthly payments--this tool gives you a schedule showing the monthly payment amount and how much interest you'll pay. See what a quarter-percent difference makes. See how a 15, 20 or 30-year loan compares. Know what you're getting into, then analyze what happens if you pay it off more quickly--say by paying an extra payment each year or by paying an extra amount each month. Or both. This easy-to-use tool can literally help you save tens of thousands of dollars on any home, car, or other large loan.
