The 5 Factors That Determine Your Credit Score
Want to know how credit scores are calculated? It's simpler than you think. Your FICO score — the most common credit score used by lenders — breaks down into five factors. Each factor has a different weight, meaning some matter more than others. Understanding how credit scores are calculated helps you focus your efforts where they'll have the biggest impact. Read on to learn where credit score ranges fit in.
Payment History (35% of Your Score)
This is the biggest piece of your credit score. Lenders want to know: do you pay your bills on time? Your payment history includes credit cards, loans, and even utility bills if they're reported to the bureaus.
One missed payment can ding your score. But it gets worse the more recent it is. A late payment from six months ago hurts less than one from last month.
To improve here: never miss a due date. Set up automatic payments if you tend to forget.
Credit Utilization (30% of Your Score)
This measures how much of your available credit you're actually using. If you have a $1,000 credit limit and a $900 balance, your utilization is 90%. If you have a $100 balance, it's 10%.
Lenders like to see utilization below 30%. The logic is simple: if you're using most of your credit, you might struggle to pay it back. Understanding your credit utilization ratio is key to improving your score quickly.
To improve here: pay down your balances or ask for a credit limit increase. Even paying a few hundred dollars off can drop your utilization significantly.
Length of Credit History (15% of Your Score)
This factors in how long your accounts have been open. The longer your credit history, the more data lenders have about your habits. Old accounts help your score, even if you don't use them.
This is one reason closing old credit cards can hurt your score — it shortens your average account age.
To improve here: keep old accounts open even if you're not using them. If you're just starting out, learn how long it takes to build credit and be patient. Your score will improve as you age your accounts.
Credit Mix (10% of Your Score)
This looks at the variety of credit you have. Lenders want to see that you can handle different types of credit: credit cards, car loans, mortgages, student loans, and so on.
If you only have credit cards, diversifying helps. If you already have a car loan and student loans, you're in good shape.
To improve here: don't open accounts just for variety. Use the credit types that make sense for your life. Having one credit card and making on-time payments is better than opening three new cards you don't need.
New Credit Inquiries (10% of Your Score)
This tracks how often you've recently applied for credit. When you apply for a credit card or loan, the lender pulls your credit. That's called a hard inquiry, and it dings your score slightly — usually 5-10 points.
Multiple hard inquiries in a short time suggest you're desperate for credit, which worries lenders.
To improve here: only apply for credit when you actually need it. Space out applications by at least a few months. Checking your own credit is a soft inquiry and doesn't count against you.
FICO vs VantageScore — Different Formulas, Same Idea
FICO is the most common score, but VantageScore is another option. Both use the same five factors, but weight them differently. FICO weights payment history more heavily; VantageScore gives a bit more weight to credit utilization.
Most lenders use FICO, so that's the score to focus on. But the strategy is the same either way: pay on time, keep balances low, and build a long history. Want to get a 700 credit score? Master these five factors.

FAQ
What's a good credit score? FICO scores range from 300 to 850. Scores above 670 are generally considered good. Above 740 is very good. Above 800 is excellent.
How often does my score update? Your credit report updates when creditors report new information, usually monthly. Your score can change whenever your report changes.
Can I improve my score quickly? Some improvements are quick: paying down a balance can lower your utilization in weeks. Others take time: building a long payment history takes months or years.
Does checking my own credit hurt my score? No. Soft inquiries (when you check your own credit) don't affect your score. Only hard inquiries from lenders do.
How long do negative items stay on my report? Late payments stay for 7 years. Bankruptcy lasts 10 years. Collections and charge-offs also stick around for 7 years.
