Credit Score Impact Calculator (USA) — See Exact Point Changes for 25+ Actions

Q: Will checking my own credit score lower it?

No. Checking your own credit is a soft inquiry and has zero impact on your FICO or VantageScore. Only hard inquiries from credit applications affect scores.

Q: How many points does a hard inquiry drop my score?

A single hard inquiry typically lowers your FICO score by 5-10 points. Multiple inquiries for the same loan type within 45 days (rate shopping) count as one inquiry under FICO 10.

Q: How long does a late payment stay on my credit report?

A late payment remains on your credit report for 7 years from the original delinquency date. Its impact lessens over time, especially after 2 years of on-time payments.

Q: Is it better to pay off a collection or leave it?

Paying a collection updates the status to 'paid collection,' which is slightly better for FICO 9 and 10, but may not remove it from your report. Under the 2023 medical debt rule, paid medical collections under $500 are removed.

Q: Does closing a credit card hurt my score?

Yes, closing a card can lower your score by increasing your overall credit utilization (losing available credit) and eventually reducing your average credit age.

Q: How fast can I raise my score by 50 points?

Depending on your profile, reducing high utilization (below 30%) can boost your score by 20-50 points within 30-60 days. Removing errors or becoming an authorized user also helps quickly.

Q: What's the fastest way to go from 650 to 720?

Pay down revolving balances below 10% utilization, dispute any inaccuracies, and ensure all payments are on time for at least 6 months. Adding a seasoned authorized user tradeline can also accelerate improvement.

Q: Does paying my credit card twice a month help my score?

Paying multiple times can lower the reported balance (utilization) if timed before the statement closing date. This can improve your score temporarily, but the payment history itself only counts once per month.

Q: Do multiple auto-loan inquiries count as one?

Yes, FICO scoring models treat multiple auto, mortgage, or student loan inquiries within a 45-day window as a single inquiry to allow for rate shopping.

Q: How does the 2024 medical-debt rule affect my score?

As of 2023-2024, paid medical collections are no longer reported. Unpaid medical debt under $500 is also excluded from credit reports. Larger unpaid medical bills may still appear but have reduced impact in FICO 10.
