A sudden credit score drop usually comes from one of five things: a missed or late payment, a hard inquiry, a new account, a higher credit utilization ratio, or an error on your report

Your credit score moves because the data behind it changed. The three major credit bureaus — Equifax, Experian, and TransUnion — track your payment history, how much credit you are using, how long you have had accounts open, the mix of credit types you carry, and recent inquiries into your credit. When one of these shifts, your score shifts with it. Most drops happen because you missed a payment, used more of your available credit, or a lender pulled your credit report to make a lending decision.

The size of the drop depends on what happened and where your score started. A missed payment hurts more if you have a long history of on-time payments. A new credit card hurts less if you already have several accounts. Understanding which of these five things caused your drop is the first step to knowing whether it will recover on its own or whether you need to take action.

Key Takeaways

  • Late or missed payments cause the largest drops and stay on your report for seven years, though their impact weakens after two years.
  • Hard inquiries (when a lender checks your credit to decide whether to lend) lower your score by a few points and fall off after 12 months.
  • Opening a new account temporarily lowers your score because it reduces your average account age and adds a hard inquiry, but the effect fades over time.
  • Using more of your available credit raises your utilization ratio and lowers your score, but the damage reverses as soon as you pay the balance down.
  • Errors on your credit report — accounts that are not yours, wrong payment dates, or duplicate entries — can be disputed directly with the bureau that reported them.

Late and missed payments are the heaviest hit

A single missed payment can drop your score by 100 points or more, depending on how high it was to begin with and how clean your payment history is. The damage is largest if you have never missed a payment before. If you miss a payment by 30 days, the lender reports it to the credit bureaus. If you miss by 60 days, the damage deepens. At 90 days, it deepens again.

The missed payment stays on your report for seven years from the date you missed it. However, its impact on your score weakens over time. A missed payment from six months ago hurts less than one from last month. A missed payment from three years ago hurts much less. After seven years, the bureaus must remove it entirely.

If you are currently behind on a payment, contact your lender before the 30-day mark if you can. Many lenders will work with you on a payment plan or a temporary deferment if you reach out first. Once the payment is reported as late, the damage is done, but stopping the slide at 30 days instead of letting it reach 90 days makes a real difference to your score later.

Hard inquiries from lenders checking your credit

When you apply for a credit card, a loan, or a mortgage, the lender pulls your credit report to decide whether to lend to you. This is called a hard inquiry. It shows up on your credit report and lowers your score by a few points — usually between 5 and 10 points per inquiry. Multiple hard inquiries in a short time (within 14 to 45 days, depending on the scoring model) often count as a single inquiry, so shopping for a mortgage or car loan in a two-week window does not multiply the damage.

Hard inquiries stay on your report for 12 months and stop affecting your score after that. If you see a hard inquiry you did not authorize — meaning you did not apply for credit — you can dispute it with the bureau. Unauthorized inquiries are a sign of fraud and should be reported to the Federal Trade Commission at IdentityTheft.gov.

Soft inquiries, by contrast, do not lower your score. These happen when you check your own credit, when an employer runs a background check, or when a company you already do business with reviews your account. Only hard inquiries count against you.

New accounts and the average age of your credit

Opening a new credit account lowers your score in two ways. First, it adds a hard inquiry (which you just read about). Second, it lowers the average age of all your accounts. Credit scoring models reward you for having a long history of credit. When you add a brand-new account to the mix, the average age drops, and your score drops with it.

The effect is temporary. As the new account ages, it stops dragging down your average. After a few months, the new account stops hurting your score and may even help it by adding to the variety of credit types you carry (having both revolving credit like a credit card and installment credit like a car loan is better than having only one type).

If you recently opened a new account and your score dropped, this is normal and expected. The score will recover without you doing anything. The exception is if you opened the account and then immediately ran up a high balance — in that case, the utilization ratio (explained below) is also working against you, and paying down the balance will help.

Credit utilization: how much of your available credit you are using

Your credit utilization ratio is the total balance on all your revolving credit accounts divided by your total credit limits. If you have three credit cards with a combined limit of $10,000 and you are carrying a combined balance of $4,000, your utilization is 40 percent. Scoring models prefer utilization below 30 percent. If your utilization jumps from 20 percent to 60 percent, your score will drop.

The good news is that utilization changes are immediate and reversible. As soon as you pay down the balance, your score begins to recover. Unlike a missed payment, which stays on your report for years, a high utilization ratio only hurts you while it is high. If you recently made a large purchase or transferred a balance to a new card, this is likely why your score dropped. Paying down the balance will fix it.

Utilization is calculated across all your accounts, not per card. If you have one maxed-out card and two empty ones, your overall utilization is still high. Spreading balances across multiple cards does not help. The only thing that helps is lowering the total balance or raising your total credit limits.

Errors and fraud on your credit report

Sometimes a score drops because of something that is not your fault. An account might be reported under your name when it belongs to someone else. A payment date might be wrong. A closed account might still be showing as open. These errors can lower your score and should be corrected.

You can order a free credit report from each of the three bureaus once per year at AnnualCreditReport.com. This is the official site run by the three bureaus themselves. Review each report for accounts you do not recognize, wrong payment dates, or duplicate entries. If you find an error, you can dispute it directly with the bureau that reported it. The bureau must investigate within 30 days and remove the error if it cannot verify it.

If you see accounts you did not open or inquiries you did not authorize, this may be a sign of identity theft. Report it to the Federal Trade Commission at IdentityTheft.gov. The FTC will create a recovery plan and send you a letter you can use to dispute fraudulent accounts with the bureaus and with creditors.

How long it takes for your score to recover

Recovery depends on what caused the drop. A high utilization ratio can recover in one or two billing cycles once you pay the balance down. A hard inquiry fades over 12 months. A new account stops hurting your score after a few months. A missed payment takes much longer — it will still affect your score after two years, though the damage is much smaller by then.

The best thing you can do to recover is to build a pattern of on-time payments going forward. Every month you pay on time, your score moves in the right direction. If you missed a payment, make the next 12 payments on time and you will see real improvement. If you have a high utilization ratio, pay it down and keep it down. The bureaus are always looking at your most recent behavior, and recent behavior matters more than old behavior.

Frequently Asked Questions

How much will my score drop if I miss one payment?

A single missed payment can drop your score by 50 to 150 points depending on how high your score was and how clean your history is. The drop is larger if you have never missed a payment before. The exact amount varies by scoring model and lender.

Will my score recover if I pay a late payment now?

Paying a late payment stops it from getting worse (it will not go to 60 days late or 90 days late), but the damage from the missed payment itself is already done. The payment will stay on your report for seven years. However, paying it off shows future lenders you resolved the problem, and your score will gradually improve over time.

Can I remove a hard inquiry from my credit report?

Hard inquiries fall off your report after 12 months on their own. You cannot remove them early unless the inquiry was unauthorized (meaning you did not apply for credit). If you did not authorize it, dispute it with the bureau that reported it or report it to the Federal Trade Commission.

Does checking my own credit score lower it?

No. Checking your own credit is a soft inquiry and does not lower your score. Only hard inquiries from lenders count against you. You can check your score as often as you want without any penalty.

What should I do if I see an account on my credit report that is not mine?

Dispute it with the bureau that reported it. You can file a dispute online, by mail, or by phone. The bureau must investigate within 30 days. If the account is fraudulent, also report it to the Federal Trade Commission at IdentityTheft.gov so you can get a recovery plan and a letter to send to creditors.
