According to, the typical person will likely pay $279,000 of interest over the course of a lifetime.

When you borrow money, whether from a mortgage lender or a credit card, you pay for that privilege, and those payments are called "interest." How much you pay, however, depends on your credit score. created a calculator for people to figure out just how much their loans and lines of credit may cost them over the course of a lifetime (40 years).

Their calculations are based on mortgage payments, auto loans, and credit card payments. To get to the final number, assumed:

a 30-year-mortgage with a 4.5% interest rate a 6.075% interest rate for a term of 64 months (9 cars) a 15% credit card interest rate

We decided to try it out for a 35-year old man living in New York.

Here's what it looked like.

Step 1: Enter your age, gender, state of residence, and credit score. Step 2: Enter your mortgage payment, auto loans, and credit card payments. provides averages for these payments, which we used for our calculations. You can choose to keep their averages or enter your own numbers for a better estimate.

And you're done. You can move the slider to see what you would pay if your credit score was higher or lower.

Here are the costs calculated for us, according to credit score:

Excellent credit score of 740 or higher: $480,386 Good credit score of 680-739: $521,556 Fair credit score of 620-679: $603,740 Poor credit score of 550-619: $755,304 Bad credit score of 550 or lower: $910,109

We also tried the calculation as a woman while keeping everything else the same. While it isn't clear why, the worse the credit score, the greater the difference in the amount of interest paid by men and women. For example, using an excellent credit score, women paid only $1,000 more. However, using a bad credit score, the difference was $5,000.
