Understanding your credit score: what it really measures and why it matters

You check your credit score on one app and see 720. You check another and see 695. A lender pulls your report and tells you it's 710. None of these numbers are wrong—and that's exactly what confuses most people about credit scores.

"Credit scores can be different for the credit you're pulling," explains Brenda Hughes Executive Vice President and Chief Operating Officer at First Fed. "If we pull a credit score for an auto loan, it's going to give a different score than if we pull for a mortgage loan, because they're looking at different analytics."

Additionally, three major credit bureaus—Experian, TransUnion, and Equifax—each maintain their own records and scoring models. Within each bureau, multiple versions exist (FICO 9, FICO 10, FICO 10T). Not every lender reports to every bureau, and consumers can now self-report payments like rent or cell phone bills to select agencies.

The result: your credit profile looks slightly different depending on who's looking and what model they're using.

What your score measures and what it doesn’t

Credit scores distill your financial history into a single number. The main ingredients: payment history, credit utilization, length of credit history, credit mix, and public records like collections or bankruptcies.

The bureaus weight these factors differently using proprietary formulas. "We can tell you what they are looking at," Hughes notes, "but we can't tell you how they derive the actual score."

A score of 680 or above puts borrowers in a strong position by industry standards. Most models cap at 850.

But… your credit score is not the whole picture of what lenders evaluate.

"We're not looking just at credit score," Hughes explains. "We're looking at ability to repay, collateral, and the overall credit profile holistically."

Tips to Know and Tools to Use

  • Understand the 30% rule: Credit utilization—how much of your available credit you're using—carries significant weight. Hughes recommends keeping your credit utilization at 30% or less of your limits.
  • Building credit from scratch: For anyone starting fresh, Hughes emphasizes a simple principle: borrow only what you can manage. Two strategies also work well. Secured loans let you borrow against a certificate of deposit, building payment history with minimal risk. Secured credit cards work similarly—you deposit funds that become your credit limit.
  • Monitor monthly:  Hughes recommends checking your credit at least monthly if not more frequently. First Fed offers the Savvy Money tool via online banking, where customers can monitor their credit daily without affecting their score, since it's a soft pull. The tool also includes a score simulator to test how actions like paying down a card can help. It also helps you ensure nobody is stealing your identity or taking credit out under your name.
  • Fixing errors: While rare, First Fed customers can initiate credit disputes right within Savvy Money, or file directly with each bureau.

 

Patience and the Payoff

While it may take some time for these actions to translate into results on your credit score, paying down debt is one way to accelerate the timeline. "If you actually retire debt, you can see an improvement in score quicker than if you're just making minimum payments on time," Hughes says. "Generally, within six months, you can start to see improvement if you make measurable changes."

Beyond loan approval, a healthy credit score translates to better interest rates, lower fees, and more purchasing power.

"It gives you more buying power," Hughes notes. "A lower interest rate allows you to qualify for a little bit more of a mortgage or auto loan."

That little bit can make a significant difference over the long term.
