Soft vs hard credit inquiries: what each one really does to your score

Every credit check is either a soft inquiry or a hard inquiry, and the difference decides whether your score moves. Confusion between the two keeps people from checking their own credit and from shopping for better rates — both of which are free of consequence when you know the rules.

A soft inquiry is a read-only look at your file. Checking your own score, prequalifying for offers, background checks by employers, and promotional screening by card issuers are all soft. They appear only on the version of your report that you see; lenders never see them, and no scoring model counts them. You could soft-check your credit a hundred times a day with zero effect.

A hard inquiry happens when you formally apply for credit and a lender pulls your file to make a decision. It is visible to other lenders and typically costs a few points — usually fewer than five — with the effect fading over a few months and the inquiry dropping off entirely after two years. One hard inquiry is a rounding error; a dozen in six months is a pattern lenders read as risk.

The rate-shopping protection matters most for loans: scoring models treat multiple hard inquiries for the same loan type within a shopping window as a single inquiry. The window is 14 days in older models and up to 45 days in newer ones. Practical rule: compress your mortgage, auto, or personal loan applications into two weeks and the score cost is the same as applying once.

Credit cards do not get the shopping-window treatment — each card application is its own hard inquiry. This is exactly why checking approval odds before applying matters: every card application you were never going to win is a hard inquiry paid for nothing.

The pattern to internalize: prequalify softly and widely, apply formally and narrowly. Modern prequalification uses real underwriting criteria, so you can see estimated rates and approval odds across many lenders without your file recording anything, then spend your hard inquiry on the one offer you actually want.
