How to calculate your borrowing capacity

This is one of the most convenient online tools we've found, because it lets you try out different payment, term, and principal combinations until you find one that suits your needs. It also computes your total payments and total interest bill, and even provides an amortization schedule of your loan. Here's how it works:

Fill out three of the following four factors:
  • principal amount
  • monthly payment amount
  • length of the loan, in months
  • interest rate
and solve for the fourth factor.

What you can enter and/or solve for:

Principal amount. Fill in the price you've been quoted (or expect to pay). If you're buying new, give yourself some cushion if you'd like to include taxes and fees in your principal. If you're looking to see how much car you can afford, leave this space blank.

Monthly payment. Fill in an amount you'd be comfortable putting towards a car payment each month. Try to avoid filling in the maximum or minimum you'd pay, but rather a number that fits your budget well.

Loan term. Fill in the length of the loan you intend to apply for. Car loans are generally available for 12, 24, 36, 48, 60, and 72 month terms. If you want to find out how long it will take you to pay off your car, fill in the other info and leave this blank.

Interest rate. Unless you've already been approved for a loan, you'll have to guess here. Interest rates vary from around 5% to 8% right now, for excellent to fair credit borrowers. (Try 5% for excellent, 6% for good, 8% for fair.) Borrowers with poor credit may have to pay 10%, and those with very poor credit may have to pay up to 20%.
