If you’ve checked your credit score and the number surprised you — or you just can’t figure out why it won’t go up — you’re not alone. A low credit score almost always comes down to a handful of specific, fixable things. Here’s how to diagnose exactly what’s hurting yours and what to do about each one.
The five things that make up your credit score
Your FICO score — the most widely used credit score — is calculated from five factors. Understanding what they are is the first step to fixing your number:
- Payment history (35%). Whether you pay on time. This is the single biggest factor.
- Credit usage (30%). How much of your available credit you’re using. Lower is better.
- Length of credit history (15%). How long your accounts have been open. Older is better.
- Credit mix (10%). Having different types of credit — cards, loans, etc.
- New credit (10%). How recently you’ve applied for new accounts.
Now let’s go through the most common reasons scores drop and exactly how to address each one.
Reason 1: You missed a payment — or paid late
This is the most damaging single thing you can do to your credit score. One missed payment can drop your score by 50–100 points and stays on your credit report for 7 years.
What to do: Set up autopay for at least the minimum payment on every account. Even if you can’t pay the full balance, paying the minimum on time protects your payment history. If you missed a payment recently, catch up immediately — the damage from a single missed payment stops growing once you’re current again.
Reason 2: You’re using too much of your credit limit
This is called credit utilization — the percentage of your available credit you’re currently using. If your credit card limit is $1,000 and your balance is $800, your utilization is 80%. That’s crushing your score.
The sweet spot is under 30%. Under 10% is even better.
What to do: Pay down your balances. If you can’t pay them down quickly, ask your card issuer for a credit limit increase — same balance, higher limit, lower utilization, higher score. You can also spread spending across multiple cards to keep each one’s utilization low.
Reason 3: You have no credit history
If you’re young or new to credit, you might have a low score simply because there’s not enough data. You can’t have a great score without any accounts.
What to do: Open a starter credit card — a student card or secured card — use it for small purchases, and pay the full balance every month. In 6–12 months you’ll have a score. In 2 years you could have a good one. The only way to build credit history is to start.
Reason 4: You have a collection account
If an unpaid debt got sent to a collection agency — a medical bill, an old phone contract, a gym membership you forgot to cancel — it shows up on your credit report as a collection and does serious damage.
What to do: Pull your free credit report at AnnualCreditReport.com and look for collections. For recent collections, paying them off or negotiating a settlement removes the negative impact over time. For older ones (approaching the 7-year mark), they’ll fall off your report automatically. Don’t pay old collections without understanding whether it restarts the clock in your state.
Reason 5: You applied for too much credit at once
Every time you apply for a credit card, loan, or any form of credit, it creates a hard inquiry on your report. One inquiry is a minor ding. Five in three months looks like financial desperation to lenders and drops your score meaningfully.
What to do: Space out credit applications. Only apply for new credit when you actually need it. Hard inquiries disappear from your report after 2 years and stop affecting your score after about 12 months.
Reason 6: You closed old accounts
Closing a credit card account — even one you don’t use — can hurt your score two ways: it reduces your total available credit (increasing utilization) and it can shorten your average account age.
What to do: Keep old accounts open, even if you don’t use them. If there’s an annual fee on a card you don’t use, call and ask to downgrade to a no-fee version. Keep the account open, keep the history, keep the available credit.
Reason 7: There’s an error on your report
About 1 in 5 credit reports contains an error significant enough to affect the score. A payment marked late that you paid on time. An account that isn’t yours. A debt that was discharged but still shows as owed.
What to do: Get your free report at AnnualCreditReport.com. Read through every account. Dispute anything that’s wrong directly through the bureau’s website. By law they must investigate and respond within 30 days. Correcting a single error can move your score significantly.
How fast can your score recover?
- Paying down high utilization: can improve your score within one billing cycle (30–45 days)
- Removing an error: typically 30–60 days after dispute
- Recovering from a missed payment: gradual improvement over 12–24 months of clean payment history
- Building credit from nothing: 6 months to get a score, 1–2 years to get a good one
Credit scores are not permanent. Every single factor that damages your score can be fixed with time and the right habits. Start with the highest-impact items first — utilization and payment history — and the number will move faster than you expect.
