What Factors Affect Your Credit Score?

Key Takeaways

  • FICO® scores are built from five factors: payment history (35 percent), amounts owed (30 percent), length of credit history (15 percent), credit mix (10 percent) and new credit (10 percent).
  • Payment history is the single largest factor in your FICO score, and a payment 30 or more days late can significantly lower your score.
  • Keeping your credit utilization below 30 percent of your available limits is a straightforward way to support a stronger score.
  • VantageScore® uses the same five categories but assigns them different weights, giving payment history a higher 41 percent share and credit mix a larger 20 percent share.
  • Your income, age, employment status and the act of checking your own credit score do not factor into standard credit scores.

Credit score factors are the categories that scoring models use to evaluate your creditworthiness and assign your score. A credit score is a three-digit number, typically ranging from 300 to 850, that lenders use to gauge how likely you are to repay a debt. The higher your score, the better the terms you are likely to receive on loans, credit cards and other financial products.

Understanding what makes up your credit score starts with knowing which scoring model applies. Different lenders calculate your score based on a set of factors that may vary slightly by model. This post focuses on FICO®, the model most widely used in lending decisions, and then covers how VantageScore® differs so you have a complete picture.

The 5 FICO® Credit Score Factors

The 5 factors of credit score used in the FICO model cover every major dimension of how you manage credit. Factors affecting credit score are not weighted equally: payment history alone carries more than a third of your total score, while credit mix and new credit each account for just 10 percent. Knowing how each factor is calculated tells you exactly where to focus if your score needs work.

1. Payment History: 35%

Payment history is a record of whether you have paid your credit accounts on time and in full. It is what affects your credit score the most, accounting for 35 percent of your FICO score, because lenders consider past payment behavior the strongest predictor of future repayment. Consistent on-time payments build this category in your favor; a single payment 30 or more days late can cause a notable score drop.

Your payment history reflects more than on-time marks. Late payments, collections, charge-offs and bankruptcies all appear here, and most remain on your credit report for seven to 10 years. Lenders see both the severity of past issues and how recently they occurred. For a deeper look at factors that impact your credit score after a delinquency, our guide on score drops after paying off debt covers what to expect.

  • Set up autopay for at least the minimum payment on every account so a missed due date never becomes a late mark.
  • If you do miss a payment, pay it before 30 days pass. Most lenders do not report to the bureaus until the account is 30 days past due.
  • Contact your lender if you are struggling. Hardship arrangements, deferred payments or modified terms can protect your payment history while you recover financially.

2. Amounts Owed: 30%

Amounts owed, also called credit utilization, measures how much of your available revolving credit you are currently using. It accounts for 30 percent of your FICO score. To calculate your utilization ratio, divide your total revolving balances by your total credit limits across all revolving accounts. A ratio above 30 percent signals to lenders that you may be overextended, even if you make every payment on time.

If your balances are high relative to your limits, lenders reviewing your scoring factors may view you as a higher credit risk. This is true even when you pay in full every month, because many card issuers report your balance as of the statement closing date rather than the payment date.

  • Pay down revolving balances before the statement closing date to report a lower utilization ratio to the bureaus.
  • Request a credit limit increase on accounts in good standing. A higher limit lowers your utilization ratio without requiring you to reduce spending.
  • Spread balances across multiple cards rather than concentrating them on one, since per-card utilization also factors into your score.

3. Length of Credit History: 15%

Length of credit history accounts for 15 percent of your FICO score. This factor looks at four elements: the age of your oldest account, the age of your newest account, the average age of all your accounts and how recently each account has been used. A longer, more established history generally produces a stronger score because it gives lenders more data to evaluate.

Consumers with a thin or short credit file face a disadvantage here because lenders have limited evidence of long-term reliability. FICO requires at least one active account reporting for a minimum of six months before it can generate a score. Closed accounts also complicate the picture: an account you stop using may eventually fall off your report, effectively erasing the history it contributed.

  • Keep your oldest credit card open and active, even if you use it infrequently, to preserve the age of your oldest account.
  • Avoid opening several new accounts at once. Each new account lowers the average age of all your accounts.
  • Use older accounts occasionally so they remain active and continue contributing to your credit history.

4. Credit Mix: 10%

Credit mix accounts for 10 percent of your FICO score. It reflects the variety of credit types in your file, including revolving accounts (credit cards and lines of credit) and installment loans (auto loans, mortgages and student loans). Lenders look favorably on borrowers who can responsibly manage different kinds of debt, not just one type.

A file limited to a single account type will score lower in this category than one showing a range of account types managed well over time. The impact is modest at 10 percent, so it rarely justifies opening new accounts just to diversify. If you are looking to build credit across multiple account types, focus on accounts you genuinely need rather than opening credit purely for the mix.

  • Do not open an installment loan or credit card solely to improve credit mix. The score benefit is modest and the new account may temporarily lower your score.
  • If you already maintain a loan and a credit card responsibly, that combination is sufficient to support this factor.
  • A credit-builder loan from a credit union can add an installment account to a thin file without requiring a strong prior credit history to qualify.

5. New Credit: 10%

New credit accounts for about 10 percent of your FICO score and reflects how often you have applied for credit recently. Each application triggers a hard inquiry, which can modestly lower your score. Certain factors — such as multiple hard inquiries within a short period — can temporarily signal financial stress to lenders, even when the applications reflect rate shopping for a mortgage or auto loan rather than financial distress.

One or two hard inquiries rarely produce a meaningful score change, but a cluster of applications within a few months can raise a concern. FICO groups mortgage and auto-loan applications made within a short window into a single inquiry to accommodate rate shopping. Credit card applications do not receive the same treatment.

  • Apply for new credit only when you need it, and space applications out over time where possible.
  • Check your own credit before applying so you know your approximate standing. Self-checks are soft inquiries and have no effect on your score.
  • When rate shopping for a mortgage or auto loan, complete all applications within a 14 to 45-day window so FICO treats them as a single inquiry.

Credit Score Factors that Affect Your VantageScore®

VantageScore® is a credit scoring model developed jointly by TransUnion®, Experian® and Equifax® as an alternative to FICO. It uses the same underlying data from your credit report, but weights its categories differently. Most lenders, particularly for mortgages, auto loans and major credit cards, rely on FICO, making it the more consequential model for most borrowers. VantageScore is used more frequently in soft-inquiry applications and by some financial technology lenders.

Understanding both models gives you a more complete view of how your credit habits are being evaluated. Cleaning up your credit across any of these areas tends to improve your standing in both models simultaneously. The six VantageScore® categories and their approximate weights are listed below.

  • Payment History (41 percent). On-time payments carry even more weight in VantageScore than in FICO, reinforcing that payment consistency is the most important habit across all major scoring models.
  • Credit Mix (20 percent). VantageScore places significantly more emphasis on the variety of your credit accounts than FICO does, making a diverse range of installment and revolving credit more impactful here.
  • Credit Utilization (20 percent). Similar to FICO’s amounts owed factor, this measures your revolving balances as a percentage of your total credit limits. Keeping it below 30 percent is a sound target under both models.
  • Recent Credit Behavior (11 percent). This category captures new inquiries and recently opened accounts, rewarding borrowers who are not aggressively seeking new credit.
  • Total Balances (6 percent). The total dollar amount owed across all account types, including installment loans, factors into this category, not just revolving balances.
  • Available Credit (2 percent). The amount of credit you have available but are not currently using contributes modestly to your VantageScore.

What Doesn’t Affect Your Credit Score?

Knowing what negatively affects a credit score is only part of the picture. Equally useful is understanding what the major scoring models ignore entirely. Several common financial details have no bearing on standard credit scores, and worrying about them is energy better spent elsewhere.

  • Checking your own credit score. Reviewing your own credit report or score generates a soft inquiry, which has no effect on your score. You can check as frequently as you like without any scoring consequences.
  • Income and employment status. Your salary, job title and employment history do not appear on your credit report and are not factored into any standard credit score, though lenders may ask about them separately when evaluating a loan application.
  • Age. Your age is not a scoring factor. Older consumers often carry stronger scores because they have had more time to build a long credit history, but age itself has no direct effect on the calculation.

It is also worth understanding that derogatory marks on your credit report, such as late payments or collections, do affect your score significantly. Most drop off after seven years. If you believe a derogatory item is being reported inaccurately, you have the right to dispute it with the bureaus. Another option is a goodwill letter requesting that a creditor remove an isolated late payment from an otherwise clean account.

Credit Score Factor FAQs

What is a Good Credit Score?

A good credit score is generally considered 670 or higher on the standard 300 to 850 scale used by FICO and VantageScore. Scores from 670 to 739 are typically rated as good, 740 to 799 as very good and 800 and above as exceptional. Lenders set their own thresholds, so the score needed to qualify for a specific product or rate varies by institution.

What Credit Score Do You Need to Purchase a Home?

The minimum credit score to purchase a home depends on the loan type. Conventional loans typically require a score of at least 620, while FHA loans may accept scores as low as 580 with a 3.5 percent down payment or as low as 500 with a 10 percent down payment. VA and USDA loans do not set a universal minimum, though individual lenders generally require 580 to 640. Higher scores generally qualify for better interest rates, which can meaningfully reduce the total cost of the loan.

How Rare is a Credit Score Over 800?

A credit score above 800 is relatively uncommon. According to FICO data, roughly 23 percent of consumers score 800 or higher. Reaching this range typically requires years of on-time payments, consistently low credit utilization, a long credit history and minimal new credit applications. Consumers in this range generally qualify for the most favorable rates lenders offer.

What Can I Do if I Don’t Have a Credit Score?

If you do not have a credit score, the most effective approaches are to open a secured credit card, become an authorized user on a family member’s account or take out a credit-builder loan from a credit union or community bank. Each strategy adds positive payment history to your file. FICO requires at least one active account open for a minimum of six months before it can generate a score.
