Every time you formally apply for a loan or credit card, the lender pulls your credit report to evaluate the application. This is a hard inquiry, and it is the single most misunderstood mechanic in how a CIBIL score actually moves, mainly because the damage from one inquiry and the damage from five inquiries in the same month are not the same thing scaled up. They behave differently.
Hard Inquiry vs Soft Inquiry, First
A soft inquiry happens when you check your own score, when a lender screens your profile for a pre-approved offer without a formal application, or during certain background checks. It does not affect your score, and you can check your own credit report as often as you like without any cost to it.
A hard inquiry happens specifically when you submit a formal credit application and the lender pulls your report to underwrite it. This is the only kind of inquiry that carries weight in the score calculation, and it happens regardless of whether the application is eventually approved or rejected. A rejection doesn't undo the inquiry; the record of the lender checking your report stays either way.
How Much a Single Hard Inquiry Actually Costs
Across lender and credit-education sources, a single hard inquiry is most commonly cited as costing somewhere in the range of 5 to 10 points, with some variation depending on the strength of the file it's attached to. A borrower with a long, strong credit history and a score already above 750 tends to see a smaller dip from one inquiry, sometimes closer to the low end of that range or even less. A borrower with a thin or short credit file tends to see a larger relative impact from the same single inquiry, since there's less established history to absorb it against.
Treat any number more precise than this range with some scepticism. Bureaus don't publish an exact, universal per-inquiry deduction, and several sources online cite oddly specific figures, in some cases attached to statistics that aren't independently verifiable, so a "your score will drop by exactly X points" claim should be read as an estimate, not a guarantee.
Why Multiple Inquiries in a Short Window Hurt More Than the Sum
This is the part that catches most borrowers off guard. Several hard inquiries within a short period, commonly cited as a window of a few weeks to a couple of months, don't just add up individually. They are read by the scoring model as a pattern, sometimes described as looking "credit-hungry," which signals to a lender that you may be actively and urgently seeking multiple sources of credit at once. This pattern-level read compounds on top of the individual per-inquiry deductions, which is why borrowers who get rejected once and then quickly apply to four or five more lenders in response often see a noticeably larger cumulative drop than five separate small deductions would suggest on their own.
How Long an Inquiry Stays on Your Report
A hard inquiry remains visible on your credit report for up to two years from the date it was made. Its actual effect on the score, however, is not constant across that period. The impact is generally strongest in the first several months and tapers off well before the two-year mark, provided no new inquiries are added in the meantime. An inquiry from a year and a half ago sitting quietly on an otherwise clean file is a very different signal to a lender than the same inquiry made two weeks ago alongside three others.
Comparing Loan Offers Without the Damage
The practical fix for this is straightforward, but requires acting before you apply rather than after. Many lenders and comparison platforms offer a soft, pre-qualification eligibility check that estimates your likely terms without triggering a hard inquiry, since no formal application has been submitted yet. Using this to compare a few lenders' likely terms, before choosing one to formally apply to, gets you the comparison you actually need without the compounding cost of several real applications. This is a more useful sequence than applying to a first-choice lender, getting rejected, and then applying to several more in quick succession, which is precisely the pattern that does the most cumulative damage to the score you're trying to protect.
