Formula Used

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

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 divided by 12)
n = Number of payments (loan term in months)

The calculator then adds any additional fees to the principal amount before applying the formula.

Worked Example

Let's walk through an example to see how the calculator works.

Example Calculation

Suppose you're applying for a $20,000 auto loan with a 5% annual interest rate over 4 years (48 months). You also have $500 in additional fees (tax and title fees).

Total principal = $20,000 + $500 = $20,500
Monthly interest rate = 5% / 12 = 0.4167%
Number of payments = 48
Apply the loan payment formula:

Calculation Steps

Monthly Payment = $20,500 * (0.004167(1 + 0.004167)^48) / ((1 + 0.004167)^48 - 1)

Monthly Payment ≈ $452.34

So, your estimated monthly payment would be $452.34, including the additional fees.
