Impact: Severe — 35% of Score

Missing a Payment

This is the single biggest thing that can hurt your credit score. Payment history makes up 35% of your FICO score. One missed payment — even by 30 days — can drop your score by 80-180 points depending on where you start. A 750 score can fall to 590 from a single late payment. And it stays on your report for 7 years. Set up autopay for at least the minimum on every account. Never let a payment go 30 days late.

Impact: High — 30% of Score

High Credit Utilisation

Credit utilisation is how much of your available credit limit you are using. If your credit card limit is $5,000 and your balance is $4,000 — your utilisation is 80%. That is doing serious damage to your score. Lenders want to see utilisation below 30%. Below 10% is ideal. You do not need to have a zero balance. But carrying a high balance relative to your limit signals financial stress to lenders — and your score drops accordingly.

Impact: Medium-High — 15% of Score

Short Credit History

The length of your credit history matters. Closing an old credit card account — even one you never use — can hurt your score because it shortens your average account age. If you have a card from 5 years ago with no annual fee and no balance — keep it open and use it for a small purchase every few months. The age of that account is helping your score every single day.

Impact: Medium — 10% of Score

Too Many Hard Inquiries

Every time you apply for credit — a card, a loan, a car finance — the lender does a hard inquiry on your credit report. Each one drops your score by 5-10 points. Apply for 5 things in a short period and that is 25-50 points gone. Only apply for credit when you genuinely need it. Use soft inquiry tools like Credit Karma to check eligibility before making a formal application.

Impact: Medium — 10% of Score

No Mix of Credit Types

Lenders like to see that you can handle different types of credit responsibly — credit cards, instalment loans, car finance. If you only have one type it limits your score ceiling. This is the least impactful factor so do not open accounts just to diversify. But if you are already managing multiple types well — that is helping your score more than you might realise.

Impact: Severe — Stays 7 Years

Collections, Charge-offs and Bankruptcies

If a debt goes to collections it is one of the most damaging things that can appear on your credit report. A charge-off — when a lender writes off your debt as a loss — is nearly as bad. Bankruptcy is the nuclear option and stays for 7-10 years. If you have any of these on your report the priority is paying down new debt responsibly and disputing any errors. Negative items lose impact over time as positive history builds.

Impact: Hidden Damage

Errors on Your Credit Report

1 in 5 Americans has an error on their credit report according to the FTC. Accounts that are not yours. Payments marked late that were not. Balances that are wrong. Every error is dragging your score down for something that never happened. Check your report free at AnnualCreditReport.com and dispute anything that is not accurate. This is the fastest free fix for most people.

What is the number one thing that hurts your credit score?

Missing a payment is the single biggest damage to your credit score. Payment history makes up 35% of your FICO score and a single missed payment can drop your score by 80-180 points. Set up autopay for at least the minimum on every account to protect your score.

Does checking your credit score hurt it?

No. Checking your own credit score is a soft inquiry and does not affect your score at all. Only hard inquiries — when a lender checks your credit for an application — can lower your score. You can check your score as often as you want through Credit Karma or your bank without any damage.

How quickly can bad things affect your credit score?

Very quickly. A missed payment appears on your report as soon as it is 30 days late and the score drop happens almost immediately after it is reported. High utilisation is updated every billing cycle so running up a credit card balance can hurt your score within a month.

Can closing a credit card hurt your score?

Yes. Closing a credit card reduces your total available credit which increases your utilisation ratio. It also shortens your average account age if it was an older card. Both of those hurt your score. Keep old cards open even if you rarely use them — especially ones with no annual fee.

How long do negative items stay on your credit report?

Most negative items — late payments, collections, charge-offs — stay on your report for 7 years from the date of the original missed payment. Bankruptcies can stay for 10 years. The good news is their impact fades significantly over time especially as you build positive history alongside them.
