Calculating your auto loan payment with a trade-in involves several factors including the vehicle price, loan amount, interest rate, loan term, and trade-in value. This calculator helps you determine your monthly payment while accounting for your existing vehicle's value.

How to Use This Calculator

To calculate your auto loan payment with trade-in:

Enter the purchase price of the new vehicle

The calculator will show you the loan amount after accounting for your trade-in value, then calculate the monthly payment using standard auto loan formulas.

Formula Explained

The auto loan payment with trade-in is calculated using the standard auto loan formula:

Monthly Payment = P * (r(1 + r)^n) / ((1 + r)^n - 1) Where: P = Loan Amount (Purchase Price - Down Payment - Trade-In Value) r = Monthly Interest Rate (APR / 12 / 100) n = Number of Payments (Loan Term in Years * 12)

This formula accounts for the reduced loan amount after applying your trade-in value to the purchase price.

Worked Example

Let's calculate a monthly payment for a $30,000 vehicle with a $5,000 trade-in, $3,000 down payment, 4.5% APR, and 5-year term.

Loan Amount = $30,000 - $3,000 - $5,000 = $22,000
Monthly Rate = 4.5% / 12 = 0.375%
Number of Payments = 5 * 12 = 60
Monthly Payment = $22,000 * (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $425.45

Your estimated monthly payment would be $425.45.
