How To Calculate Credit Score
When it comes to understanding financial health, knowing how to calculate a credit score is a fundamental aspect. A credit score is a numerical representation of a consumer’s creditworthiness, which lenders use to determine the risk of lending money. This comprehensive guide will break down the components that make up a credit score and provide a step-by-step exploration of how it is calculated.
What is a Credit Score?
A credit score is a three-digit number ranging from 300 to 850, where a higher number indicates better creditworthiness. It is based on your credit history and is used by lenders, credit card companies, landlords, and sometimes even employers, to assess your financial reliability.
Components of a Credit Score
Credit scores are calculated using data from your credit report. The most commonly used scoring model is the FICO score, which derives from information provided by the three major credit bureaus: Experian, Equifax, and TransUnion. Here are the primary factors that influence your credit score:
-
Payment History (35%): This is the most significant factor and reflects whether you've paid past credit accounts on time. Late payments, delinquencies, and collections negatively impact this segment.
-
Amounts Owed (30%): This factor, also known as credit utilization, represents the ratio of your outstanding balances to your total available credit. Lower credit utilization rates are traditionally better.
-
Length of Credit History (15%): The longer your credit history, the higher your score can be. This includes factors like the age of your oldest account, your newest account, and the average age of all your accounts.
-
New Credit (10%): This factor considers recent requests for new credit and the opening of new credit accounts. Frequent requests for new credit can lower your score temporarily.
-
Credit Mix (10%): A mix of different types of credit accounts, such as installment loans, retail accounts, credit cards, and mortgage loans, can positively affect your score.
Steps to Calculate Your Credit Score
Step 1: Obtain a Credit Report
Your credit score is founded on the data contained in your credit report. Under federal law, you are entitled to receive a free copy of your credit report every 12 months from each of the three major credit bureaus through AnnualCreditReport.com.
Step 2: Evaluate Payment History
Assess the timeliness of your bill payments. Late payments, collections, and the presence of charge-offs will severely affect this category. It’s recommended to aim for a 100% positive payment history.
Step 3: Calculate Credit Utilization Ratio
Calculate the total balances on all revolving credit accounts and divide by the total credit limits on those accounts. For instance, if you have a total credit card balance of $2,000 with a combined available credit of $10,000, your credit utilization ratio is 20%. Maintaining a ratio below 30% is advised.
Step 4: Determine Length of Credit History
Examine how long each of your accounts has been open. The age of your oldest account, the age of your newest account, and the average age of your accounts all contribute to this factor. Generally, older accounts positively influence your score.
Step 5: Review Inquiries and New Accounts
Review your report for hard inquiries or opened accounts in the last 12 months. Hard inquiries made for new credit applications can slightly reduce your credit score, so it’s best to apply for new credit only when necessary.
Step 6: Analyze Credit Mix
Evaluate the different types of accounts you have. Having a mix of accounts like a credit card, car loan, and mortgage can be beneficial.
Example of a Credit Score Calculation
While exact calculations used by credit scoring models are proprietary, here's a hypothetical breakdown that can be used to understand the impact of various factors:
Factor | Percentage | Example Impact on Score Calculation |
---|---|---|
Payment History | 35% | Score Impact +100 if no late payments in history |
Credit Utilization | 30% | Score Impact +60 if utilization is 20% |
Length of History | 15% | Score Impact +30 for an average account age of 5 years |
New Credit | 10% | Score Impact +25 with minimal recent inquiries |
Credit Mix | 10% | Score Impact +25 with diverse accounts maintained |
In this scenario, the individual could have a potential score of 240 out of 300, assuming no adverse elements are affecting their score.
Frequently Asked Questions
1. How accurate are the free credit scores available online? Online free credit scores, like those provided by Credit Karma or Credit Sesame, offer useful insights but may not be the exact scores lenders use. They can still be beneficial for tracking general trends.
2. Can closing an old credit card affect my credit score? Yes, it can. Closing an old credit card can impact the length of your credit history and increase your credit utilization ratio if the available credit decreases, potentially lowering your score.
3. Does checking my own credit score affect it? No, checking your own credit score generates a soft inquiry, which does not affect your credit score.
Strategies to Improve Your Credit Score
-
Pay Bills on Time: Your payment history is a substantial part of your credit score. Set up reminders or automatic payments to avoid missed payments.
-
Reduce Debt: Work on paying off your debt to lower your credit utilization ratio. Consider strategies like the snowball or avalanche method to manage debt effectively.
-
Limit Hard Inquiries: Only apply for new credit when necessary. Multiple hard inquiries in a short time can lower your score.
