What helps and what hurts your credit score
Ranked by actual impact and by how fast each one works — because "improve your credit" is useless advice without knowing which lever to pull first.
What helps
Payment history is 35% of the score. This is the foundation and nothing substitutes for it. Set autopay for at least the minimum on every account.
Amounts owed is 30%. Balances re-report each cycle, so this is the only major factor that can improve immediately. Under 30% is common guidance; under 10% scores best.
Issuers usually report the statement-closing balance. Paying in full after the statement closes still reports high utilization. Same money, better timing.
Protects both average account age (15%) and total available credit (part of the 30%). A no-fee card you never use is still working for you.
Raising the denominator lowers utilization without paying down anything. Ask whether the issuer uses a soft pull first.
Free, and the only legitimate form of credit repair. Get free reports at AnnualCreditReport.com and dispute inaccuracies directly with the bureau.
Same-purpose inquiries inside a 14–45 day window count as one. Not shopping costs far more than the inquiry does.
What hurts
The single most damaging routine event. Under 30 days late is a fee and possibly a rate change, but is generally not reported to bureaus — pay before the 30-day line at all costs.
Major derogatory marks. FICO 9+ ignores paid collections, but many lenders still run older versions where paid ones still count.
High utilization is heavily penalised — but it carries no memory. Pay it down and the next report largely undoes the damage.
Cuts available credit and eventually shortens average account age. Two hits from one action.
Each unrelated hard inquiry is minor; a cluster of them across different products signals distress.
Chapter 13 generally reportable for 7 years, Chapter 7 for 10. Sometimes still the correct decision — that is a conversation for a nonprofit credit counselor or an attorney.
Myths worth killing
If you only do one thing
Set up autopay for at least the minimum on every account you have. Payment history is the largest factor, missed payments are the most damaging routine event, and the overwhelming majority of missed payments are forgetfulness rather than inability to pay. Autopay converts the biggest risk in your credit file into a solved problem.
Then, if you carry card balances, work on utilization — it is 30% of the score and the only part that can improve before next month. The utilization guide covers the timing detail that makes the difference.
