Will a personal loan affect my ability to get a car loan?

DTI impact: Every monthly debt payment increases your DTI. If you take a $10,000 personal loan at 15% APR over 48 months, you add a $278/month payment to your DTI. A lender evaluating your car loan application will see this payment and reduce the car loan amount you qualify for by roughly $278/month of capacity at the same DTI threshold.

Credit score impact: Taking a personal loan (hard inquiry plus new account plus reduced average account age) typically reduces your FICO by 5-15 points temporarily. Over 6-12 months of on-time payments, the score usually recovers. If you apply for a car loan within 3-6 months of opening a personal loan, you may be working with a temporarily lower score.

The optimal sequence: If you need both a personal loan and a car loan in the near future, get the car loan first. Getting the auto loan while your DTI and credit score are optimal, then taking the personal loan, preserves the best terms on both.

Alternatively, do both simultaneously: Applying for both loans within a 14-day window means only one grouped credit inquiry impact (rate-shopping protection). However, both lenders see the other application in process and may factor it into their decisions.

In practice: If the personal loan is $5,000-$10,000 with a payment under $200/month, and your income is $4,000+/month, the DTI impact on car loan eligibility is likely minimal. The concern is more significant if the personal loan is large relative to your income.
