Formula Explained

The auto payment calculator uses the standard auto loan formula to calculate your monthly payment:

Auto Loan Formula

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

Where:

P = Principal loan amount (loan amount - down payment)
r = Monthly interest rate (annual rate / 12)
n = Number of payments (loan term in years * 12)

This formula accounts for the principal amount, interest rate, and loan term to determine your monthly payment.

Using the calculator:

Loan amount: $27,000
Interest rate: 4.5%
