Your credit score usually determines your interest rate and APR. If you have good credit and choose a short loan term, you’ll typically have a good APR. With a low credit score, you’ll likely have a higher APR. That said, the APR on a car loan includes interest and fees, while the interest rate does not.
When your lender calculates the interest rate before fees, they might use simple or precomputed interest.
If you have low or limited credit, don’t worry! You can try to find a cosigner to score better terms on your loan. You can also make a large downpayment. Lenders will typically offer lower interest rates to borrowers who pay large amounts up front.
