Enter the loan amount you're considering (e.g., $25,000 for a new car).

Formula Used

The auto loan payment is calculated using the standard loan payment formula:

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

Where:

P = Principal loan amount
r = Monthly interest rate (Annual rate / 12)
n = Number of payments (Loan term in years × 12)

This formula calculates the fixed monthly payment required to pay off the loan over the specified term, including both principal and interest.

Worked Example

Let's calculate an example auto loan payment:

Example: You're considering a $25,000 loan at 4.5% annual interest for 5 years.

Monthly interest rate = 4.5% / 12 = 0.375% or 0.00375

Number of payments = 5 × 12 = 60

Monthly payment = $25,000 × (0.00375 × (1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)

Calculated monthly payment = $452.34

Total interest paid = ($452.34 × 60) - $25,000 = $1,120.20

This example shows that with a $25,000 loan at 4.5% interest over 5 years, your monthly payment would be approximately $452.34, with $1,120.20 paid in interest.
