Paying off your auto loan early can save you thousands in interest. Our early auto payoff calculator helps you determine exactly how much you'll save by making extra payments or paying off your loan ahead of schedule.
How the Early Auto Payoff Calculator Works
The early auto payoff calculator estimates your savings by comparing the total interest paid on your loan with and without early payments. The calculation takes into account your current loan balance, interest rate, and the amount of extra payments you plan to make.
Key Assumptions
This calculator assumes you'll make all extra payments at the same time each month and that your interest rate will remain constant. It also assumes you'll make the minimum required payments on time while making your extra payments.
When to Use This Calculator
This tool is most useful when you're considering:
- Making bi-weekly payments instead of monthly
- Paying off your loan early to save on interest
- Comparing different loan payoff strategies
- Understanding how extra payments affect your loan term
The Formula Used
The early auto payoff calculator uses the following formula to determine your savings:
Savings = (Total Interest Without Extra Payments) - (Total Interest With Extra Payments)
Where:
- Total Interest Without Extra Payments = (Loan Balance × Monthly Interest Rate × Loan Term)
- Total Interest With Extra Payments = Sum of all interest payments made over the loan term with extra payments
The calculator uses the amortization formula to determine how your loan balance changes over time with extra payments. The amortization formula is:
Monthly Payment = P × [r(1 + r)^n] / [(1 + r)^n - 1]
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in months)
Worked Example
Let's look at an example to see how the early auto payoff calculator works. Suppose you have a $20,000 auto loan with a 5% annual interest rate and a 48-month term.
Without Extra Payments
Your monthly payment would be $452.47, and you would pay a total of $2,214.40 in interest over the life of the loan.
With $100 Extra Payments Each Month
By making an extra $100 each month, you would pay off your loan in 36 months instead of 48. Your total interest paid would be $1,214.40, saving you $1,000 in interest.
Note
The actual savings may vary slightly depending on when you make your extra payments within each month.
