How a Hard Inquiry Actually Affects Your Credit Score — and How Long It Lasts

Every time you submit a full application for credit — a credit card, an auto loan, a mortgage — the lender pulls your file, and that pull shows up on your credit report as a hard inquiry. People tend to treat that moment as either meaningless or catastrophic, and it's neither. The actual mechanics are more specific, and more forgiving, than the folklore around them.

The points lost are usually small

A single hard inquiry typically costs fewer than five points on a FICO Score, according to FICO's own consumer-education material on credit inquiries. For most people with an established credit history and multiple accounts, that's genuinely minor — it can be the difference between two scores in the same lender's approval range, not the difference between approval and denial. The exception is someone with a thin file: very few accounts or a short credit history. For that borrower, one new inquiry represents a larger share of the limited information the model has to work with, so the impact can run higher than the typical single-digit hit.

What inquiries are not is cumulative in the way people fear. Checking your own score, getting pre-qualified, or having a card issuer do a promotional soft pull doesn't touch your score at all — those are soft inquiries, a different category entirely, and only you and the businesses you already work with can see them. A hard inquiry only happens when you've actually applied for something new, and it only happens once per application.

It stays on your report for two years, but your score stops counting it much sooner

This is the part that trips people up, because two different clocks are running at once. Under the Fair Credit Reporting Act, a hard inquiry can remain on your credit report for up to two years from the date it occurred, and it will still be visible to anyone who pulls your full file during that window — the Consumer Financial Protection Bureau confirms the two-year reporting period directly. But FICO scoring models only factor inquiries from the most recent 12 months into your actual score. So for the second year an inquiry is sitting on your report, it's showing up as a line item with no score effect at all. If you applied for something six months ago and your score hasn't recovered the way you expected, the inquiry itself usually isn't why — it's more likely something else in your file, like a utilization spike, that happened around the same time.

Shopping multiple lenders doesn't multiply the damage

If you're comparing rates for a mortgage, auto loan, or student loan, FICO's scoring models are built to recognize that behavior as rate shopping rather than a borrower opening several new lines of credit at once. Multiple inquiries of the same loan type made within a focused shopping window — the exact number of days varies by FICO version, generally somewhere between 14 and 45 — get treated as a single inquiry for scoring purposes. That deduplication exists specifically so comparing three lenders' mortgage rates doesn't cost three times what comparing one would. It's a narrower protection than it sounds, though: it applies to same-type installment shopping within that tight window, not to spreading applications for a credit card and a personal loan and a car loan across a season, which each get counted separately.

What this means in practice

None of this is a reason to apply for credit casually — a hard inquiry is still a real mark, and if you're already carrying several from the last year, adding another before a major application (like a mortgage) is worth timing carefully. But it also means a single hard pull for something you actually need isn't worth the anxiety it tends to generate, and a cluster of same-type inquiries from focused rate shopping isn't punished the way a handful of unrelated applications would be. If you want to see what you'd likely qualify for before deciding whether a hard pull is worth it, you can compare pre-qualified offers → with a soft pull first, and only move to a full application on the one you actually want.
