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

ActionImpactSpeed
Pay every bill on time, every time

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.

Highest
Slow to build
Lower your credit utilization

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.

High
Within a month
Pay before the statement closing date

Issuers usually report the statement-closing balance. Paying in full after the statement closes still reports high utilization. Same money, better timing.

Moderate
Within a month
Keep old accounts open

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.

Moderate
Preventive
Ask for a credit limit increase

Raising the denominator lowers utilization without paying down anything. Ask whether the issuer uses a soft pull first.

Moderate
Within a month
Dispute genuine errors

Free, and the only legitimate form of credit repair. Get free reports at AnnualCreditReport.com and dispute inaccuracies directly with the bureau.

Variable, sometimes large
Roughly 30 days
Cluster rate-shopping inquiries

Same-purpose inquiries inside a 14–45 day window count as one. Not shopping costs far more than the inquiry does.

Small
Immediate

What hurts

ActionImpactDuration
Missing a payment by 30+ days

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.

Severe
Up to 7 years on report
Collections, charge-offs, repossession

Major derogatory marks. FICO 9+ ignores paid collections, but many lenders still run older versions where paid ones still count.

Severe
Up to 7 years
Maxing out cards

High utilization is heavily penalised — but it carries no memory. Pay it down and the next report largely undoes the damage.

High
Immediate, recovers fast
Closing your oldest card

Cuts available credit and eventually shortens average account age. Two hits from one action.

Moderate
Immediate + long tail
Applying for lots of credit at once

Each unrelated hard inquiry is minor; a cluster of them across different products signals distress.

Small each, additive
~12 months
Bankruptcy

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.

Severe
7–10 years

Myths worth killing

✕ Carrying a small balance helps your score
False, and expensive. Paying in full and letting the statement report is fine — the score reads reported balances, not whether you paid interest. Carrying a balance just buys you interest charges.
✕ Checking your own credit lowers your score
False. Your own checks are soft inquiries with no score effect. Free weekly reports at AnnualCreditReport.com are the official source.
✕ You need debt to build credit
False. You need credit usage, not carried debt. A card used monthly and paid in full builds history perfectly well.
✕ Credit repair companies can remove accurate negatives
False. Nothing accurate can be legally removed before its statutory time limit. What they do — disputing entries — you can do yourself for free.
✕ Income and savings are part of your score
False. Neither appears on your credit report. Lenders consider income separately in underwriting, but it is not in the score.
✕ One score fits all lenders
False. Different bureaus, models and versions produce different numbers. Mortgage lenders typically pull older FICO versions than the one in your banking app.

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.

Frequently asked questions

What hurts your credit score the most?
Missing payments. Payment history is 35% of a FICO Score — the single largest factor — and a payment reported 30 or more days late stays on your credit report for up to seven years. Severity, recency and frequency all matter, so one recent 90-day late is worse than one old 30-day late.
Does closing a credit card hurt your score?
Usually yes. Closing a card removes its limit from your total available credit, which raises your utilization ratio even though your debt has not changed. Over time it can also lower the average age of your accounts. Closing an unused no-annual-fee card is one of the most common avoidable score reductions.
Do hard inquiries hurt your credit score?
A little, and temporarily. New credit is 10% of the score. The CFPB notes that a single inquiry typically has a small effect, that inquiries for mortgage, auto and student loans made in the 30 days before scoring have no effect, and that same-purpose inquiries within a 14 to 45 day window are counted as one.
Does paying off a collection remove it?
Paying a collection does not delete it from your report — it updates the status to paid. Under FICO 9 and later, and under VantageScore 3.0 and later, paid collections are ignored, but many lenders still use older FICO versions where a paid collection continues to count against you. Get any settlement agreement in writing before paying.
