Many believe they only have a single credit score that lenders utilize to assess creditworthiness. If only it were that easy.

In reality, you have numerous credit scores. Thankfully, they usually trend in the same direction, depending on whether you maintain good or poor credit habits. Plus, you can access these scores for free. Here's what you need to know.

Why Are There So Many Scores?

To understand this, consider that the three primary credit bureaus — Experian, Equifax, and TransUnion — gather data from financial institutions and public records to calculate your credit score. Historically, these bureaus relied on a scoring model from Fair Isaac Corp., commonly known as FICO. However, they now face competition from VantageScore, also developed by the bureaus. While less prevalent than FICO, VantageScore is rapidly gaining traction, with 12 billion scores generated last year, according to Vice President Jeff Richardson.

What's often overlooked is that each credit score has multiple variations. Just as Apple designed different models of the iPad for diverse needs, FICO and VantageScore have tailored industry-specific scores — such as auto scores for car lenders and credit card scores for card companies. Each version weighs aspects of your credit history differently. Additionally, scoring companies periodically release updates that lenders adopt to enhance their predictive accuracy regarding repayment likelihood.

Does This Impact You?

Absolutely, but don't stress too much. Before seeking a loan, many individuals check a free credit report online. It's often only when they're denied favorable financing options that they discover their lender utilized a different scoring model, resulting in a score that's 100 points lower.

It's not that the higher score was incorrect; another algorithm was simply used to generate it. Lenders might reference one, two, or three scores, potentially from various scoring models, making it challenging for you to know which one they're considering.

What Can You Do?

Focus on maintaining healthy credit habits. All these scores are derived from the same five factors, and while you can't control them precisely, positive credit practices can help keep them favorable.

Here's what you should do:

1. Always pay your bills promptly.
2. Maintain credit utilization below 30% across all accounts.
3. Avoid applying for unnecessary credit — it may project desperation.
4. Don't close unused credit cards unless they charge fees, as this can negatively impact utilization.
5. Aim for a diverse mix of credit types.

That's your roadmap. To boost your credit quickly, consider paying down debts or requesting credit limit increases without using the extra credit.

Stay Proactive

Another step is to monitor your credit for free. There's no need to pay for scores, as noted by Richardson. You should also pull your three credit reports annually at AnnualCreditReport.com. If you identify any discrepancies, report them to the relevant bureaus and follow up to ensure they've been corrected. Approximately 20% of credit reports contain errors, and while many don't impact scores, some can. You want to avoid that situation.
