How Credit Scores Work: 7 Factors You Can Influence

A quick note before we start: PayLess.Help is not a credit repair organization. We don't dispute items, remove information, or change your credit on your behalf — and nobody can legally promise to. This article is education only, explaining the factors that go into your score and the free rights federal law already gives you.

Your credit score affects everything from mortgage rates to insurance premiums. The difference between a 680 and a 740 credit score on a 30-year mortgage can mean paying $40,000 more in interest. Here are seven factors that shape your score — and what consumer-protection agencies like the CFPB say about each one.

First, check your credit reports for errors. Studies show that one in five Americans has an error on their credit report that could be lowering their score. Visit AnnualCreditReport.com — the only federally authorized source — to get free reports from all three bureaus. Federal law (the Fair Credit Reporting Act) gives you the right to dispute inaccuracies yourself, for free, directly with the bureaus: wrong account balances, accounts that aren't yours, and incorrect late payment records. Bureaus must investigate within 30 days, and corrections are reflected in your score.

Lower your credit utilization ratio below 30 percent, ideally below 10 percent. This is the second most important factor in your credit score. If you have a credit card with a $10,000 limit, try to keep the balance below $1,000. Pay down balances before your statement closing date, not just the due date, because the statement balance is what gets reported to the credit bureaus.

Ask for a credit limit increase on your existing cards. This instantly lowers your utilization ratio without requiring you to pay down debt. Most issuers allow you to request increases online, and many won't even do a hard credit inquiry. A higher limit with the same balance dramatically improves your utilization percentage.

Become an authorized user on a responsible family member's credit card. Their positive payment history and low utilization will appear on your credit report, which can help your file over time. This approach is most often used by young adults building credit or anyone recovering from financial setbacks. Results depend entirely on the account holder's habits — there are no guarantees.

Never close old credit cards, even if you don't use them. The length of your credit history accounts for 15% of your score. Keep old accounts open and make a small purchase every few months to prevent the issuer from closing them due to inactivity.

Set up autopay for every account to eliminate the possibility of missed payments. Payment history is the single most important factor in your credit score, making up 35% of the total. Even one missed payment can drop your score by 100 points and stays on your report for seven years.

Consider a credit-builder loan from a credit union if you're starting from scratch. These small loans hold the borrowed amount in a savings account while you make payments. Once the loan is paid off, you get the money plus an established payment history on your credit report.
