Credit Score Factors: What Actually Matters

Credit Score Factors: What Actually Matters

Your credit score influences the interest rates you pay on mortgages, car loans, and credit cards. Understanding how the score is calculated helps you focus on what actually moves the needle rather than worrying about factors that don't matter much.

FICO scores remain the dominant scoring model, though VantageScore has grown in usage. Both use similar factors with slightly different weightings.

Payment History: 35% of Your FICO Score

This is the single most important factor. Lenders want to know if you've paid past credit accounts on time. Late payments, especially recent ones, significantly hurt your score. Collections, bankruptcies, and other negative marks fall into this category too.

The good news: positive payment history compounds over time. Years of on-time payments build a strong foundation. A single late payment hurts less if you have years of perfect history than if you're just starting out.

Set up autopay for at least the minimum payment on all accounts. The most important thing you can do for your credit score is simply pay on time, every time.

Amounts Owed: 30% of Your FICO Score

This factor looks at how much of your available credit you're using, known as credit utilization. Using a high percentage of your available credit suggests you might be overextended.

The general advice is to keep utilization below 30% of your available credit. Below 10% is even better. If you have $10,000 in total credit limits, try to keep balances below $3,000 at any given time (below $1,000 for optimal impact).

Utilization is calculated when your statement closes, which is when most issuers report to credit bureaus. Paying down balances before your statement date can improve your reported utilization even if you pay in full by the due date.

Length of Credit History: 15% of Your FICO Score

This considers how long you've had credit accounts, including the age of your oldest account, the age of your newest account, and the average age of all accounts.

Longer history is generally better. This is why it's usually not recommended to close old credit cards even if you don't use them. The age of those accounts helps your score.

If you're new to credit, time is your friend. There's no shortcut here. You build history by having accounts open for years.

Credit Mix: 10% of Your FICO Score

Having different types of credit (credit cards, installment loans, mortgage) can help your score. This shows you can handle various types of credit responsibly.

That said, don't take on debt just for the sake of credit mix. This factor is less important than payment history or utilization. If you naturally have a mix of credit types, great. If not, don't force it.

New Credit: 10% of Your FICO Score

Opening several credit accounts in a short period represents greater risk, especially for people without long credit histories. Each application creates a hard inquiry on your report.

Hard inquiries typically impact your score for about 12 months, though they stay on your report for two years. Multiple inquiries for the same type of credit (like shopping for a mortgage) within a short window (14-45 days depending on the scoring model) typically count as a single inquiry.

What Doesn't Affect Your Score

Your income doesn't directly affect your credit score (though it affects your ability to get approved for credit). Your employment status, bank account balances, and investments don't factor in either.

Checking your own credit report (a soft inquiry) doesn't hurt your score. Check it regularly at AnnualCreditReport.com for free.

Building and Maintaining Good Credit

The formula for good credit is simple, even if it takes time: pay everything on time, keep credit utilization low, don't open too many accounts too quickly, and maintain accounts over time. That covers 90%+ of what matters.
