Formula Used

The auto loan calculator uses the standard mortgage 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)

This formula calculates the fixed monthly payment required to pay off the loan over the specified term.

Worked Example

Let's calculate a monthly payment for a $20,000 loan at 4.5% annual interest over 5 years (60 months):

Convert annual interest rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375 in decimal
Plug values into the formula:

Monthly Payment = $20,000 × [0.00375(1 + 0.00375)⁶⁰] / [(1 + 0.00375)⁶⁰ - 1]
Calculate the result: $20,000 × [0.00375 × 1.00375⁶⁰] / [1.00375⁶⁰ - 1] ≈ $362.46

Your monthly payment would be approximately $362.46, with a total interest paid of $3,864.00 over the 5-year term.

Frequently Asked Questions

What is the difference between APR and interest rate?: The interest rate is the cost of borrowing, while APR (Annual Percentage Rate) includes additional fees and costs associated with the loan.
How does a longer loan term affect my payments?: A longer loan term means lower monthly payments but more total interest paid over the life of the loan.
Can I pay extra toward my loan without penalty?: Many auto loans allow prepayment without penalty, which can save you money on interest.
What happens if I can't make my car payment?: If you miss payments, your lender may charge late fees, lower your credit score, or repossess your vehicle.
