Refinancing your auto loan can help you save money by lowering your interest rate or extending your loan term. Use this refinance auto loan calculator to estimate your potential savings and compare different refinancing options.
How to Use This Calculator
To use this refinance auto loan calculator, follow these simple steps:
- Enter your current auto loan balance in the "Current Loan Balance" field.
- Enter your current interest rate in the "Current Interest Rate" field.
- Enter your current loan term in years in the "Current Loan Term" field.
- Enter your new interest rate in the "New Interest Rate" field.
- Enter your new loan term in years in the "New Loan Term" field.
- Click the "Calculate" button to see your results.
The calculator will display your estimated monthly payment, total interest paid, and total cost of the loan for both your current and refinance options.
Formula Used
The calculator uses the standard auto loan payment formula to calculate your monthly payments:
Monthly Payment = P * (r(1+r)^n) / ((1+r)^n - 1)
Where:
- P = Loan principal (current loan balance)
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years multiplied by 12)
Total interest paid is calculated by subtracting the loan principal from the total cost of the loan.
Worked Example
Let's look at an example to see how the calculator works. Suppose you have a current auto loan with:
- Current loan balance: $20,000
- Current interest rate: 6% APR
- Current loan term: 5 years
You want to refinance to a new loan with:
- New interest rate: 4% APR
- New loan term: 6 years
Using the calculator, you would enter these values and click "Calculate". The results would show:
| Metric | Current Loan | Refinanced Loan |
|---|---|---|
| Monthly Payment | $378.44 | $298.56 |
| Total Interest Paid | $1,784.40 | $1,071.60 |
| Total Cost of Loan | $21,784.40 | $21,071.60 |
In this example, refinancing saves you $712.80 in interest over the life of the loan.
Current vs. Refinanced Loan Comparison
When considering refinancing your auto loan, it's helpful to compare your current loan with potential refinanced options. Here's a comparison table showing the key metrics:
| Metric | Current Loan | Refinanced Loan |
|---|---|---|
| Monthly Payment | Calculated based on current terms | Calculated based on new terms |
| Total Interest Paid | Calculated based on current terms | Calculated based on new terms |
| Total Cost of Loan | Calculated based on current terms | Calculated based on new terms |
| Interest Rate | Current APR | New APR |
| Loan Term | Current term in years | New term in years |
This comparison helps you understand the potential savings and trade-offs of refinancing your auto loan.
