You checked your credit score and the number was lower than you expected. Maybe a lot lower. It's a frustrating feeling, especially when you're not sure what went wrong.
The good news is that a low credit score usually has specific, fixable causes. Once you understand what's dragging your score down, you can start making changes. Let's look at the most common reasons.
Late or Missed Payments
Payment history is the single biggest factor in your credit score — it makes up 35% of your FICO score. Even one late payment can cause a noticeable drop, and the later it is, the worse the damage.
A payment that's 30 days late hurts, but a payment that's 60 or 90 days late hurts a lot more. And if a payment goes so far past due that it gets sent to collections, that's an even bigger hit.
The fix: Set up autopay or payment reminders for all your accounts. If you've already missed payments, the best thing you can do is start paying on time going forward. The impact of late payments fades over time.
High Credit Utilization
Credit utilization is the percentage of your available credit that you're currently using. It accounts for about 30% of your FICO score. If you have a $1,000 credit limit and a $900 balance, your utilization is 90% — and that's way too high.
Most experts recommend keeping utilization below 30%, and people with the highest scores typically keep it under 10%.
The fix: Pay down your balances as much as you can. If possible, make payments before your statement closing date so a lower balance gets reported to the bureaus. You can also ask your card issuer for a credit limit increase, which lowers your utilization ratio without changing your balance.
Short Credit History
The length of your credit history matters. If you're new to credit — maybe you just turned 18, recently moved to the U.S., or simply never needed credit before — your score will naturally be on the lower side.
Credit scoring models look at the age of your oldest account, the age of your newest account, and the average age of all your accounts. A longer history gives lenders more data to work with, which generally means a higher score.
The fix: Keep your oldest accounts open, even if you don't use them much. Time is on your side here — your score will improve as your accounts age.
Too Many Hard Inquiries
Every time you apply for a new credit card, loan, or other credit product, the lender pulls your credit report. This creates a hard inquiry, which can lower your score by a few points.
One or two inquiries won't make a big difference. But if you've applied for several credit products in a short period, the impact adds up. Lenders may also see multiple applications as a sign of financial stress.
The fix: Only apply for credit when you really need it. If you're shopping for a mortgage or auto loan, try to do all your applications within a 14 to 45-day window — most scoring models will treat multiple inquiries for the same type of loan as a single inquiry.
Negative Items on Your Report
Certain events can cause major damage to your credit score. These include collections accounts, charge-offs (when a creditor writes off your debt as a loss), bankruptcies, foreclosures, and repossessions.
These negative items can stay on your credit report for seven to ten years, and their impact is strongest when they first appear.
The fix: If the negative items are accurate, focus on building positive credit habits going forward. The impact will lessen over time. If something on your report is wrong, dispute it with the credit bureaus — you have the right to have errors corrected.
Limited Credit Mix
Credit scoring models like to see that you can handle different types of credit. Having only one type of account — say, just a credit card — gives the model less to work with. Your credit mix makes up about 10% of your FICO score.
The fix: Consider adding a different type of credit to your profile. If you only have credit cards, a credit builder loan can add an installment account to your mix. Don't open new accounts just for the sake of variety, though — only take on credit you can manage responsibly.
No Credit History at All
If you have no credit accounts in your name, you might not have a credit score at all — or you might have a very thin file that produces a low score. This is common for young adults, recent immigrants, and people who've always paid with cash or debit.
The fix: Start building credit with a secured credit card, credit builder loan, or by becoming an authorized user on someone else's account. Even small steps create a foundation for your score to grow.
How to Check What's Hurting Your Score
The best way to figure out exactly what's lowering your score is to pull your credit report. You can get free reports from all three bureaus at AnnualCreditReport.com.
Look for late payments, high balances, collections, and errors. Many credit monitoring services also provide a breakdown of the factors affecting your score, which can point you in the right direction.
Frequently Asked Questions
What is considered a low credit score?
Any FICO score below 670 is generally considered below average. Scores below 580 are in the "poor" range and can significantly limit your borrowing options and increase your costs.
Can a credit score drop significantly overnight?
Yes. A single missed payment, a maxed-out credit card, or a new collection account can cause a notable drop. Negative events typically affect your score faster than positive ones improve it.
Is it possible to have no credit score at all?
Yes. If you have no credit accounts or very limited history, you may be "credit invisible" — meaning there isn't enough data to generate a score.
How long does it take to improve a low credit score?
It depends on the cause. Paying down high balances can show improvement within one to two billing cycles. Negative items like late payments fade in impact over 12 to 24 months.
What's the single most important thing to do when your credit score is low?
Start making every payment on time. Payment history is 35% of your FICO score, and consistent on-time payments are the fastest path to meaningful improvement.
The Bottom Line
A low credit score isn't permanent. In most cases, it's caused by specific issues that you can address one at a time. Start with the biggest factors — payment history and utilization — and work your way down. Every positive step you take moves your score in the right direction.
