What a Hard Inquiry Really Costs Your Credit Score

Is Shopping for a Loan Bad for Your Credit?

You’re at a car dealership, ready to buy a reliable used sedan. The finance manager runs your information and offers you a loan. The rate seems okay. But you wonder if your local credit union could beat it. You hesitate. You’ve heard that every time a lender checks your credit, your score goes down. Does applying for a second loan to compare rates mean you’re shooting yourself in the foot?

This fear is common. It’s also largely misplaced. The impact of a credit application on your score is real, but it is smaller and more nuanced than most people believe. For nearly everyone, the benefit of shopping for a better interest rate will vastly outweigh the temporary cost to your credit score.

The Difference Between a Hard and Soft Inquiry

When a lender checks your credit history, it’s called an inquiry. But there are two different kinds, and only one affects your score.

A hard inquiry, sometimes called a “hard pull,” happens when you formally apply for credit. This includes applying for a credit card, a mortgage, an auto loan, or a personal loan. You give the lender explicit permission to check your credit as part of the application process. This is the type of inquiry that can cause a small, temporary drop in your credit score. It shows up on your credit report, and other lenders can see it.

A soft inquiry has no effect on your score. These occur when your credit is checked for reasons other than a direct application from you. Examples include:

• You checking your own credit score or report through a service like AnnualCreditReport.com.
• A credit card company checking your file to send you a pre-approved offer in the mail.
• An existing lender of yours performing a routine account review.

A soft inquiry is a background check, not a new request for debt. Scoring models ignore them completely.

The Logic Behind the Score Drop

A hard inquiry lowers your score not as a penalty, but as a reaction to a pattern of risk. Credit scoring models like FICO and VantageScore are built by analyzing the historical credit data of millions of anonymous consumers. They identify behaviors that correlate with a higher likelihood of missing payments in the future.

The data shows that people who apply for a lot of new credit in a short time are, as a group, riskier than people who do not. The scoring model cannot know your personal situation. It just sees a new application and registers it as a slight increase in risk. Are you taking on too much debt? Are you facing a financial emergency that requires you to seek new credit lines? The model sees the application as a signal of potential instability.

This is why new credit applications are a factor in your score. For the FICO score, the most widely used model, inquiries fall into the “new credit” category, which accounts for just 10% of your total score. It’s a minor ingredient compared to payment history (35%) and total debt (30%).

The Real Cost: Fewer Than Five Points

The central question is how much this really costs you. For most people, the answer is very little. According to FICO, a single hard inquiry will typically lower a person’s score by less than five points.

That drop is almost always insignificant. If your score is 790, a drop to 785 will not change the loans or interest rates you’re offered. It’s statistical noise. The person who needs to pay closer attention is someone whose score is on the cusp of a quality tier, for example, a score of 668 where 670 is the cutoff for a better rate. Even for that person, the effect is not permanent.

An inquiry’s impact also depends on your existing file. Someone with a long credit history and multiple accounts in good standing will see a smaller drop than someone who is new to credit and has a thin file. A single inquiry on a thin file represents a more significant change in that person’s credit-seeking behavior.

How Scoring Models Handle Rate Shopping

The creators of scoring models know that consumers should compare rates for big loans. The system is designed to allow it. For certain types of loans, multiple hard inquiries are grouped together and treated as a single event, as long as they occur within a short period.

This logic, often called “deduplication,” applies to mortgages, auto loans, and student loans. It does not apply to credit cards.

The shopping window varies by the specific scoring model a lender uses. Some older FICO models use a 14-day window. Newer models, including from FICO and VantageScore, use a 45-day window. Since you don’t know which version of a score your lender will pull, the safest strategy is to do all your loan shopping in a tight, two-week timeframe. If you apply for five auto loans over ten days, the score will see it as one inquiry, not five. You get the benefit of shopping around without being penalized for each application.

Applying for five credit cards in ten days, however, will result in five separate hard inquiries and a potentially larger score drop. The model views shopping for a single car loan differently than opening several new revolving lines of credit at once.

How Long the Impact Lasts

A hard inquiry has two different expiration dates. You need to know both.

1. An inquiry remains listed on your credit report for 24 months. Any lender who pulls your full report during that time can see that you applied for credit on that date.
2. An inquiry only affects your FICO score for 12 months. After one year, it no longer has any negative impact on your score, even though it is still visible on your report for another year.

The score damage heals itself. The points you lost begin to return over a few months, and by the 366th day after the application, the inquiry has zero effect on the number a lender sees.

When You Should Actually Be Cautious

Fearing hard inquiries is a mistake for most people. The financial benefit of finding a lower interest rate on a major loan is almost certain to be greater than the cost of a temporary, five-point score dip. Shaving even a quarter of a percentage point off a car loan can save you hundreds of dollars. The inquiry is a small price to pay for that savings.

Consider the average rate on a new car loan:

Shopping at three lenders to lower that rate is a clear financial win.

The one time you must be strategic about hard inquiries is in the six to 12 months before you apply for a mortgage. This is the exception. Because a mortgage is so large and long-term, even a tiny difference in your interest rate can translate to tens of thousands of dollars over the life of the loan. Lenders scrutinize mortgage applicants very closely, and a few score points can push you into a different rate tier.

If you plan to buy a home within the next year, stop applying for any other form of credit. Don’t open a new credit card for the sign-up bonus. Don’t finance a new phone. Don’t take out a personal loan. Give your score every possible opportunity to be at its maximum when you submit that mortgage application. For all other situations, an inquiry is just a minor and temporary part of using credit.

The general rate environment, driven by the Federal Reserve, also affects what lenders offer.

In a higher-rate environment, shopping around for the best terms becomes even more important.
