A single hard inquiry typically costs somewhere in the range of a few points up to about 5-10 points, depending on your overall credit file. The effect is smaller than most people assume, and it fades well before the inquiry actually drops off your report two years later — most scoring models stop counting inquiries in the score calculation after about 12 months, even though the inquiry itself remains visible on your report for the full two years.
Impact by File Thickness
| Credit File Type | Typical Point Impact | Why |
|---|---|---|
| Thick file (10+ years history, many accounts) | 1-3 points | One inquiry is a small fraction of an already-established pattern |
| Average file (3-10 years, moderate accounts) | 3-6 points | Standard impact for most consumers |
| Thin file (under 3 years, few accounts) | 6-10 points | Inquiries carry proportionally more weight when there is less other data |
The Rate-Shopping Window
Scoring models recognize that shopping for the best rate on a mortgage, auto loan, or student loan means multiple lenders will pull your credit for the same purpose in a short period. To avoid penalizing this normal behavior, both FICO and VantageScore models count multiple inquiries of the same type within a defined window as a single inquiry for scoring purposes.
| Scoring Model | Rate-Shopping Window | Applies To |
|---|---|---|
| FICO Score 8 and newer | 45 days | Mortgage, auto, and student loan inquiries |
| Older FICO models (Score 2, 4, 5) | 14 days | Mortgage, auto, and student loan inquiries |
| VantageScore 3.0 and 4.0 | 14 days | All loan types, more permissive than FICO overall |
Credit cards are treated differently. Rate-shopping windows generally do not apply to credit card applications — each card application typically generates its own separate inquiry with its own separate impact, since there is no equivalent "shopping" behavior recognized for revolving credit the way there is for installment loans.
How Long the Impact Actually Lasts
- 0-3 months: Full impact applies — this is when the point deduction is most noticeable.
- 3-12 months: Impact gradually diminishes as the inquiry ages.
- 12+ months: Most scoring models no longer factor the inquiry into your score at all, even though it remains visible on your report.
- 24 months: The inquiry falls off your credit report entirely.
When Multiple Inquiries Actually Hurt
The real risk is not one inquiry — it is opening several new accounts across different credit types in a short window, which signals higher risk to lenders regardless of what any single inquiry costs. Six or more inquiries in a short period, especially for revolving credit (credit cards) rather than rate-shopped installment loans, is the pattern that most consistently correlates with score drops and denials on subsequent applications.
Sequencing applications matters. If you are planning multiple credit applications, spacing them out and choosing issuers that pull different bureaus can prevent inquiries from stacking on the same file. See the Bureau Pull Database to check which bureau each major issuer checks before applying, and use soft-pull pre-approval tools first wherever available — they carry no score impact at all.
Have an inquiry you did not authorize? Not every inquiry on your report is legitimate. See How to Remove Hard Inquiries From Your Credit Report for what qualifies for removal and the exact dispute process.
