How Automobile Refinance Works
Refinancing replaces your old auto loan with a new loan that ideally has better terms. This may include:
- Lower interest rate
- Lower monthly payment
- Shorter or longer loan term
The calculator uses amortization principles to compare both loans.

Monthly payment is based on the loan amortization formula:
Monthly Payment = P × r × (1 + r)^n / [(1 + r)^n − 1]
Where:
- P = loan amount
- r = monthly interest rate
- n = number of months
