Lending Tree Auto Loan Calculator

The Lending Tree Auto Loan Calculator helps you estimate your monthly auto loan payments, total interest costs, and loan affordability. This tool uses standard auto loan calculation methods to provide accurate estimates based on your inputs.

How to Use This Calculator

To use the Lending Tree Auto Loan Calculator:

Enter the loan amount you're considering (e.g., $25,000 for a used car)
Select the loan term in years (common options are 3-7 years)
Enter the estimated annual percentage rate (APR) for the loan
Click "Calculate" to see your estimated monthly payment and total interest
Review the results and compare different scenarios

The calculator will show you the monthly payment amount, total interest paid over the life of the loan, and the total amount paid (principal + interest).

Formula Used

The calculator uses the standard auto loan payment formula:

Auto Loan Payment Formula

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (APR/12/100)
n = Number of payments (Loan Term × 12)

This formula calculates the fixed monthly payment for an auto loan with a fixed interest rate.

Worked Example

Let's calculate a $25,000 auto loan with a 5-year term and 5.9% APR:

Principal (P) = $25,000
Annual Interest Rate = 5.9%
Monthly Interest Rate (r) = 5.9%/12/100 = 0.004917
Number of Payments (n) = 5 × 12 = 60
Monthly Payment = $25,000 × (0.004917(1 + 0.004917)^60) / ((1 + 0.004917)^60 - 1)
Monthly Payment ≈ $472.46
Total Interest Paid = ($472.46 × 60) - $25,000 = $1,011.60

This example shows that a $25,000 loan with these terms would have a monthly payment of approximately $472.46 and total interest of $1,011.60.

Frequently Asked Questions
