If you have ever been approved for a credit card, signed a lease, or applied for a mortgage, a three-digit number quietly shaped the outcome. That number is a FICO score, the most widely used credit score in the United States. Lenders, landlords, insurers, and even some employers rely on it to predict how likely you are to repay what you borrow. Yet most Americans only vaguely understand how it works — and misunderstandings about it can cost real money in the form of higher interest rates, larger deposits, or outright denials. For a deeper dive, see our guide to small business credit.
In this guide, we explain what a FICO score is, the five factors behind it, the official score ranges from poor to exceptional, and what each range means for your borrowing power in 2026. Whether you are building credit for the first time or repairing it after a setback, understanding these ranges is the first step toward a stronger financial profile.

What Is a FICO Score?
A FICO score is a three-digit number, typically ranging from 300 to 850, that summarizes your credit risk based on the information in your credit reports. It was created by the Fair Isaac Corporation — hence “FICO” — and introduced in the late 1980s as a standardized way for lenders to evaluate borrowers. Today it is used in the vast majority of US lending decisions, from auto loans and mortgages to credit card approvals and apartment applications.
It is important to understand that a FICO score is not the same thing as a credit report. Your credit report is the detailed history — every account, payment, and inquiry. Your FICO score is the grade that a mathematical model assigns to that history. Three major credit bureaus — Equifax, Experian, and TransUnion — each maintain a report on you, so you may see slightly different FICO scores depending on which bureau’s data was used.
There are also several versions of the score. Mortgage lenders often use older FICO models, while credit card issuers may use newer ones, and banks sometimes pull an industry-specific variant such as an auto-enhanced score. These variations explain why the number on a free monitoring app does not always match the number a lender sees. The underlying principles, however, are the same across every version.
How Your FICO Score Is Calculated
FICO scores are built from five weighted factors. Payment history carries the most weight at roughly 35 percent of your score. A single 30-day late payment can shave dozens of points, while a long record of on-time payments is the single best thing you can do for your score. Collections accounts, bankruptcies, and foreclosures sit in this category and can weigh on a score for years.
Amounts owed — often called credit utilization — accounts for about 30 percent. This measures how much of your available credit you are using. If you have a $10,000 total limit and carry a $4,500 balance, your utilization is 45 percent. As a rule of thumb, keeping utilization below 30 percent helps, and below 10 percent is better still. Importantly, this factor resets monthly: paying down balances before your statement closes can lift a score quickly.
The remaining three factors are smaller but still matter. Length of credit history (about 15 percent) rewards older accounts, so keeping an old card open helps even if you rarely use it. New credit (about 10 percent) penalizes rapid bursts of applications, since several hard inquiries in a short window can look like financial distress. Credit mix (about 10 percent) favors borrowers who handle different account types responsibly, such as a mortgage alongside a revolving credit card. You can learn how to read your credit report to see exactly which accounts and inquiries are shaping your score.
FICO Score Ranges Explained
FICO groups scores into five broad bands. Knowing which band you fall in tells you, at a glance, how lenders are likely to view you. According to FICO’s published ranges, the bands are as follows:
| Score Range | Rating | Typical Lender View |
|---|---|---|
| 800–850 | Exceptional | Best rates and terms, fastest approvals |
| 740–799 | Very Good | Nearly top-tier offers, wide approval |
| 670–739 | Good | Approved for most products at competitive rates |
| 580–669 | Fair | Approved with higher rates or stricter terms |
| 300–579 | Poor | Subprime only; many applications denied |
These cutoffs are industry conventions, not legal thresholds — individual lenders set their own minimums. The 670 boundary between fair and good is particularly important in practice: it is the point where many lenders’ pricing tiers shift, and where borrowers typically start qualifying for mainstream credit cards and reasonable loan terms.
What Each Range Means for Borrowing
In the exceptional band of 800 to 850, borrowers access the lowest advertised rates on mortgages, auto loans, and credit cards, often with minimal scrutiny. A 30-year mortgage applicant at this level may pay a noticeably lower rate than someone in the good band — over a large loan, that difference compounds into tens of thousands of dollars in interest saved across the life of the loan.
The very good band of 740 to 799 is nearly as strong. Most lenders price borrowers at 740 and above into their top tiers, so climbing from 745 to 780 rarely changes an offer. The good band of 670 to 739 still earns mainstream approval: solid rewards cards, standard auto loans, and conventional mortgages are all within reach, though the very best promotional rates may be reserved for higher scores.
Things change meaningfully in the fair band of 580 to 669. Borrowers here are generally approved but pay for the privilege — higher interest rates, larger security deposits, smaller credit limits, and fewer choices. Below 580, options narrow sharply. FHA mortgages, which allow down payments with scores as low as 580 (and sometimes lower with larger down payments), become a key path to homeownership. Secured credit cards — where you deposit collateral that sets your limit — are the standard rebuilding tool. Renters in this range may face extra screening or be asked for cosigners.
How Everyday Actions Move Your Score
Small habits produce big score movements over time. Paying every bill by its due date is the foundation — payment history is the heaviest factor, and consistency matters more than perfection on any one month. Setting up automatic minimum payments ensures you never miss a due date even when life gets busy.
Credit utilization is the fastest lever. A borrower who pays a $3,000 balance down to $500 before the statement date can see a meaningful score increase within a billing cycle or two, because utilization has no “memory” in most scoring models — only the current snapshot matters. Conversely, closing an old card with a high limit can suddenly spike your utilization ratio and drop your score, which is why financial counselors usually advise against closing long-held accounts.
Other actions to watch: applying for several cards at once creates multiple hard inquiries that can dent a score for up to a year; co-signing a loan puts someone else’s behavior on your report; and simply letting a dormant account stay open costs nothing and helps your average account age.

Practical Ways to Improve Your Score
Start by getting your baseline. Under federal law you are entitled to free credit reports from each of the three bureaus — check them for errors, because incorrect late payments or accounts that are not yours can be disputed and removed, sometimes with a fast score improvement. Many banks and card issuers also provide free FICO score tracking so you can watch progress monthly.
Then follow a simple playbook:
- Automate at least the minimum payment on every account so nothing is ever late.
- Bring credit card balances below 30 percent of their limits, and below 10 percent if possible.
- Keep old accounts open to preserve your length of credit history.
- Limit new applications — space them out and only apply when you actually need credit.
- Address any collections or charged-off accounts, since settled or paid derogatory marks weigh less over time.
Building from fair to good typically takes months of consistent behavior, not days. There is no legitimate shortcut: companies that promise to erase accurate negative information are selling something the law does not allow.
