Refinancing my car loan

Refinancing my car loan

I need some advice. Any would be very appreciated! I'm thinking about refinancing my car loan and I'm not sure if doing so would really affect my monthly payment much. My current loan info: Hyundai Motor Finance Current balance 14,073.93 Current monthly payment 354.52 Current interest rate 7.75 Months to pay off- 39 I could very likely qualify for a 4.25% used car loan with Navy Federal Credit Union. Will doing so affect my monthly payment much? That, of course, is my goal. Thanks in advance for feedback!
