Paying extra on your auto loan can save you thousands in interest and shorten your loan term. Our Extra Payment Auto Loan Calculator shows you exactly how much you'll save by making additional payments, including reduced interest costs and faster payoff.
How the Extra Payment Auto Loan Calculator Works
The calculator uses the standard amortization formula to determine how extra payments affect your loan. Here's what it calculates:
When you make extra payments, the calculator recalculates your loan balance each month, applying the extra payment first to principal, then to interest. This shows you the exact savings in interest and the new payoff date.
Key Benefits of Extra Payments
- Reduce total interest paid
- Shorten loan term
- Build equity faster
- Lower monthly payments in the future
Note: Extra payments are applied to the highest interest balance first. This may affect your interest savings compared to making regular payments.
How to Use the Calculator
- Enter your current loan balance
- Input your current interest rate (APR)
- Specify your loan term in years
- Enter the amount of your regular monthly payment
- Input the amount of your extra payment
- Click "Calculate" to see your savings
The calculator will show you:
- Total interest saved
- New payoff date
- Comparison of regular vs. extra payment scenarios
- Visual chart showing your loan balance over time
Example Calculation
Let's say you have a $20,000 auto loan at 5% APR with a 5-year term. Your regular monthly payment is $389.37. If you make an extra $200 payment each month:
| Scenario | Total Interest Paid | Payoff Date |
|---|---|---|
| Regular payments only | $3,538.65 | May 2025 |
| With extra payments | $1,234.52 | December 2023 |
In this example, you save $2,304.13 in interest and pay off your loan 1 year and 5 months early by making just $200 extra payments each month.
