Credit Scores Explained
Understand how credit scores work, what the ranges mean, and how to build healthy credit — in plain, practical language.
What Is a Credit Score?
A credit score is a three-digit number that summarizes the information in your credit report. In the United States, scores typically range from 300 to 850, with higher numbers indicating lower risk to lenders. Two of the most widely used scoring models are FICO and VantageScore.
The score is not created by the government or a single bank. It is calculated by scoring companies from the credit data that lenders report to the three major credit bureaus: Equifax, Experian, and TransUnion.
Because there are three bureaus and several scoring models, you actually have multiple credit scores, which can differ slightly.

Why Credit Scores Matter
Lenders use credit scores to estimate how likely you are to repay borrowed money. Your score can affect:
- The interest rate you pay on loans and credit cards.
- Whether you are approved for credit in the first place.
- Required security deposits for utilities and rentals.
- Auto and home insurance premiums in many states.
- Background checks for certain jobs.
Even a small difference in your interest rate can add up to thousands of dollars over the life of a large loan.
How Credit Scores Work
Scoring models analyze the information in your credit report and apply different weights to different factors. Payment history and credit utilization carry the most weight in most models. The model produces a single number that lenders can quickly compare across applicants.
Because models and reporting can differ, the same person may see slightly different scores from different bureaus or models. The good news is that the healthy habits that build one score tend to build them all.

Major Factors That Influence Scores
While the exact weights vary, these are the factors that most models consider:
- Payment history: whether you pay your bills on time.
- Credit utilization: how much of your available credit you use.
- Length of credit history: the age of your accounts.
- New credit: recent applications and new accounts.
- Credit mix: the variety of credit types you manage.
What Is a Good Credit Score?
Scores generally fall into broad ranges. While specific thresholds vary by lender, a common breakdown looks like this:
A score of 700 or above is generally considered good by most lenders. Once you reach the excellent range, further increases rarely change the terms you are offered.

Credit Score vs Credit Report
Your credit report is the detailed history of your credit activity. Your credit score is a number that summarizes that history. Think of the report as the raw data and the score as the quick summary.
Errors in a report can lower your score, which is why reviewing all three of your reports regularly is so important.
