How Credit Affects Your Finances

Take an auto loan, for example. Auto buyers with excellent credit will get lower interest rates, maybe even ​3 percent​ in today's market, for those with excellent credit scores of ​750​ and above. On the other hand, borrowers with lower credit scores, like ​600​ and below, could be paying closer to ​10 percent.


If you had a car loan of ​$40,000​ payable over seven years at an interest rate of ​3 percent​, you would pay a total interest cost of ​$4,397. if you had a lower credit score and had to pay ​10 percent​ for the same loan, your total interest paid would be ​$15,870​. This is a difference of ​$11,473.


This additional interest cost of ​$11,473​ is money that you could have used to put in your savings account or build up a down payment for a house. Instead, it was used to pay interest because of a low credit score.

From these calculations, you can see the impact a bad credit score can have on your personal finance.

What's in a Credit Score?

Here are the five factors that make up a credit score and their weight:


  • Payment history:​ 35 percent
  • Utilization of available credit card debt:​ 30 percent
  • Average age of accounts:​ 15 percent
  • Mix of debts:​ 10 percent
  • New accounts:​ 10 percent

Generally, these are the categories of credit scores:


  • Excellent:​ 720 and above
  • Good:​ 690 to 719
  • Fair:​ 630 to 689
  • Poor:​ 300 to 629

Each of the three major credit bureaus — Experian®, Equifax® and TransUnion® — start with the Fair Isaac Corporation (FICO) algorithm, but have distinct credit scoring models that weigh each of the factors differently. So, you'll see slight differences in the classifications of these scores.


Improving Your Credit Score

You don't have to carry a low credit score all your life. There are steps you can actively take to build credit to improve your score and strengthen your financial health.

Payment history:​ Paying all your bills on time is the most important factor in your credit score. Never have a delinquency of ​30 or 60 days​ or more. Late payments will stay on your credit report for up to seven years. Look at your schedule of due dates for bill payment, and make sure you always have enough cash in your bank account to cover them. For added security, you could set up your bills with automatic payments.


Credit utilization rate:​ If you have credit card lines that total $6,000, and you owe $3,600, your credit utilization ratio is 60 percent. The goal is to keep this ratio to ​30 percent​ or less. It's best to keep your credit utilization under ​10 percent.​ If any of your credit card companies give you a credit limit increase, and you keep the same credit card balances, your utilization ratio will go down.


Length of accounts:​ It'll take time to build up a credit history of older accounts with a consistent record of on-time payments. Continue to use your existing accounts responsibly and pay down the balances. You can strengthen this factor by having another person with a good credit score and older account histories add you as an authorized user. Their good records will bolster your score.


Mix of credit accounts:​ You'll get points added to your credit score if you have a mix of types of credit that include credit cards, installment loans, student loans and mortgages.

New accounts:​ Don't apply or open a new credit card account. Each new credit application will create a hard inquiry that will temporarily lower your credit score.
