What Hurts Your Credit Score the Most?
The factors that drag your credit score down the most, ranked by impact — from late payments to high utilization — and what to do about each one.
If you want to fix your credit, it helps to know what’s breaking it. Credit scores come from a handful of factors, and they don’t all carry the same weight. Here’s what does the most damage, roughly in order of impact.
1. Missed and late payments
Payment history is the single largest factor in most scoring models. It often makes up around 35% of your score. A single payment reported 30+ days late can knock off 60 to over 100 points, and it can stay on your report for up to seven years. The fix is simple to say and hard to keep up. Pay every bill on time, every month. Automating at least the minimum payment is the easiest insurance.
2. High credit utilization
Utilization is how much of your available credit you’re using, and it’s the second heaviest hitter. Maxing out cards signals risk even if you never miss a payment.
- Keep total utilization under 30%.
- Under 10% is even better for your score.
- Paying down balances is one of the fastest ways to see improvement, because utilization updates with each billing cycle.
3. Collections and charge-offs
When a debt goes unpaid long enough, it may be charged off by the original creditor and sold to a collection agency. Both events are serious negatives. If the reporting is accurate and current, it’ll stay for years. Collections that are duplicated, misreported, or unverifiable, however, are disputable under the FCRA.
The most damaging items are also the ones most worth checking for errors. Collections in particular are frequently reported with mistakes.
4. Too many hard inquiries
Every time you apply for credit, the lender usually pulls your report, creating a hard inquiry. One or two won’t hurt much. A cluster of applications in a short window can ding your score and signal that you’re hungry for credit. (Checking your own credit is a soft inquiry and never hurts.) Space out your applications, and only apply when you actually need to.
5. A short or thin credit history
Length of credit history rewards patience. The age of your oldest account and the average age of all your accounts both factor in. That’s why closing your oldest card can backfire. It can shorten your history and raise your utilization at the same time. If you’re early in your credit life, time itself is part of the cure.
6. A lack of credit mix
This is a smaller factor, but a real one. Scoring models like to see that you can responsibly manage different types of credit, such as a credit card alongside an installment loan. Don’t take on debt you don’t need just to diversify. A healthy mix, built naturally over time, does help your score.
Putting it together
The biggest levers are the first two: pay on time and keep balances low. Those two habits alone fix most score problems over time. Beyond that, check your reports for inaccurate negatives, especially collections and late payments, and dispute anything that’s wrong. When the errors are numerous or stubborn, a specialist can help you build a stronger case than a generic dispute letter ever could.
