Auto Refinance Calculator – Should You Refinance?

Refinancing your auto loan can save you money if you qualify for a lower interest rate than your current loan. This calculator shows you the monthly savings, total savings, and break-even point — so you can make a data-driven decision.

When to Consider Refinancing

• Your credit score has improved since you took out the original loan.
• Interest rates have dropped since your purchase.
• You want to lower your monthly payment by extending the term.
• You have at least 12 months remaining on your loan (less time means fewer savings).

Break-Even Point

If there are refinancing fees, your break-even is the number of months needed before your cumulative monthly savings exceed those fees. If you plan to pay off the loan before the break-even, refinancing may not save you money.

Watch Out For

• Extending the term — can lower monthly payments while increasing total interest paid.
• Prepayment penalties on your current loan (rare but check your contract).
• Negative equity — lenders typically won't refinance an underwater loan.
