Paying off your auto loan early can save you thousands in interest payments. Use our calculator to determine exactly how much you'll save by making extra payments or refinancing your loan.
How Auto Loan Early Repayment Works
Auto loan early repayment refers to paying off your auto loan before the scheduled maturity date. There are two primary ways to do this:
- Extra principal payments: Making additional payments beyond your regular monthly payment.
- Loan refinancing: Taking out a new loan with better terms to replace your existing auto loan.
Early repayment can significantly reduce your total interest payments, but it may not always be the best financial decision. Consider your financial situation and goals before making extra payments.
Benefits of Early Repayment
The main benefits of early repayment include:
- Lower total interest paid over the life of the loan
- Reduced monthly payments if you refinance
- Potential tax benefits if you itemize deductions
- Freedom from monthly payments sooner
Considerations Before Early Repayment
Before making extra payments or refinancing, consider these factors:
- Your current financial situation and ability to make extra payments
- The cost of refinancing (if applicable)
- Whether you'll need the vehicle during the repayment period
- Potential changes in interest rates
Formula and Assumptions
The calculator uses the following formula to determine early repayment savings:
Total Interest Saved = Original Total Interest - New Total Interest
Where:
- Original Total Interest = Original Loan Amount × Original Interest Rate × Original Loan Term (in years)
- New Total Interest = (Original Loan Amount - Extra Payments) × Original Interest Rate × (Original Loan Term - Extra Payments / Monthly Payment)
Assumptions:
- Interest rates remain constant
- No prepayment penalties
- All extra payments are applied to principal
- Monthly payments are calculated using the standard amortization formula
Worked Example
Let's calculate the savings for a $20,000 auto loan with a 4.5% APR over 5 years (60 months) with an extra $500 payment each year.
Original monthly payment: $389.85
Original total interest: $4,795.50
New loan term: 4.5 years (54 months)
New monthly payment: $425.59
New total interest: $2,962.50
Total interest saved: $1,833.00
By making the extra payments, you would save $1,833 in interest over the life of the loan.
