Ninety percent of lenders use the FICO score when making lending decisions, making it the most popular credit score in the US⁽¹⁾. Because it’s the dominant credit scoring model nationwide, it’s wise to check your FICO credit score before you apply for new financing to know your credit position.

So what is a FICO score and how’s it calculated? Importantly, what’s a good FICO score to have?

What is a FICO score?

The FICO score is a three-digit credit risk score that ​​data analytics company FICO, originally Fair, Isaac and Company, launched in 1981⁽²⁾. Developed for the financial services industry as a way to standardize credit evaluation of potential borrowers, the FICO score has since become the most widely-used credit score in the US and an industry standard for lenders.

The three major US credit reporting agencies — Experian, Equifax and TransUnion — all use the FICO scoring model to develop their own unique version of the FICO score based on the data they collect on consumers.

The FICO score is one of two main credit scores in the US; the other being the VantageScore. Experian, Equifax and TransUnion launched the VantageScore in 2006 as a joint venture to compete with the FICO score⁽³⁾.

2 types of FICO credit scores

FICO scores come in two main types — base scores and industry-specific scores. Every few years, FICO releases a new version of its different credit scores⁽⁴⁾. Experian, Equifax and TransUnion all use base scores and industry-specific scores across credit card decisioning, mortgage lending and the auto industry.

The most common FICO score is FICO Score 8.

Here are the types of FICO credit scores and their different versions:

	Experian	Equifax	TransUnion

How FICO scores are calculated

FICO scores are calculated based on five main factors:

• Payment history — 35%. This is your track record for making credit payments on time. At 35%, late payments can impact your score significantly, especially after the 150-day mark. At this point, creditors may charge off your account and send the unpaid balance to collections.
• Amounts owed — 30%. Using too much of your available credit and carrying debt from month to month could convey to lenders that you’re overextended, which could be interpreted as a high risk for default.
• Length of credit history — 15%. A longer credit history can boost your FICO score, especially if you’ve consistently paid your balances on time.
• Credit mix — 10%. Creditors look at your ability to manage different types of credit, such as credit cards, charge cards and mortgages. A mix of installment loans and revolving credit can enhance your score.
• New credit — 10%. New credit applications trigger hard inquiries on your report, which can stay on your credit report for two years. FICO only considers hard inquiries from the last 12 months, but many new applications could indicate to a lender that you’re desperate for credit.

What’s a good FICO score?

FICO scores range from a low of 300 to a perfect 850. A higher number tells lenders that you’re a dependable borrower and low-risk, resulting in a higher likelihood of approval, favorable rates and flexible terms.

Lenders uphold standards that vary across loan types and the company you’re working with, though you can get an idea of how you’re viewed using broad rating categories.

Rating	How credit issuers see your score	FICO score range
Poor	With a credit score well below the average score of US consumers, may be viewed as a high-risk borrower	Less than 580
Fair	Below the average score of US consumers, but many lenders will approve loans with this score	580–669
Good	Near the average score of US consumers and most lenders consider this a good score	670–739
Very good	An above-average score, this score demonstrates a dependable borrower	740–799
Exceptional	Consider to be low-risk borrowers, with a credit score well above the average score of US consumers	800+

How to improve your FICO score

With payment history and debt levels amounting to 65% of your overall FICO score, the best way to improve your score is to always make payments on time and in full. This demonstrates to lenders that you’re a responsible borrower and will have the greatest impact on your efforts to improve your score.

If you don’t have credit, prioritize establishing a credit file. Use options like secured credit cards, hybrid credit-building cards or becoming an authorized user on someone else’s credit card to create and build your credit history.

FICO score vs. VantageScore

While the FICO score is the most widely-used credit score in the US, the three major credit bureaus use both FICO and VantageScore scoring models when rating consumers’ credit. Both produce a score ranging from 300 to 850, but while they consider a lot of the same information, they calculate their scores differently⁽⁵⁾.

Both use credit data for millions of consumers from the three main credit bureaus, but their factors and weightings of those factors are different. The VantageScore considers the following factors for its newest VantageScore 4.0 model:

• Payment history – 41%
• Depth of credit – 20%
• Credit utilization – 20%
• Recent credit – 11%
• Balances – 6%
• Available credit – 2%

Bottom line

To mitigate risk in lending, potential lenders and creditors leverage your FICO score and other tools designed to analyze and anticipate your future financial behavior. A high FICO score indicates to lenders that you’re responsible with credit, giving you a better chance of securing a loan, credit card or mortgage at favorable rates and terms. Since the FICO score is the most popular credit score in the US, it’s wise to understand what goes into its calculation and find your credit score to stay on top of your credit position.
