Formula Used

The calculator uses the standard auto loan payment formula:

Monthly Payment Formula

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]

Where:

M = Monthly payment
P = Principal loan amount (loan amount - down payment)
i = Monthly interest rate (annual rate / 12)
n = Number of payments (72 months)

This formula calculates the fixed monthly payment for a loan with a fixed interest rate over a set period.

Worked Example

Let's calculate a 6-year auto loan with these details:

Loan amount: $25,000
Down payment: $5,000
Annual interest rate: 4.5%
Loan term: 72 months

Principal amount (P) = $25,000 - $5,000 = $20,000

Monthly interest rate (i) = 4.5% / 12 = 0.375% or 0.00375

Number of payments (n) = 72

Using the formula:

Calculation Steps

M = $20,000 [ 0.00375(1 + 0.00375)^72 ] / [ (1 + 0.00375)^72 - 1 ]

M ≈ $20,000 [ 0.00375 × 1.296 ] / [ 1.296 - 1 ]

M ≈ $20,000 [ 0.004755 ] / 0.296

M ≈ $20,000 × 0.01572 ≈ $314.40

Your monthly payment would be approximately $314.40, with a total interest of about $1,728 over 6 years.

Interpreting Results

When you calculate your auto loan, consider these key points:

Monthly Payment: This is your fixed payment each month
Total Interest: Shows how much interest you'll pay over the loan term
Amortization Schedule: Visual breakdown of principal and interest payments
APR vs. Interest Rate: The APR (Annual Percentage Rate) includes all loan costs, while the interest rate is just the interest portion

Compare different loan scenarios to find the best option for your budget.

Frequently Asked Questions

How accurate is this calculator?: The calculator uses standard financial formulas and provides accurate results based on the inputs you provide. However, actual loan terms may vary depending on your lender's specific conditions.
Can I use this for refinancing?: Yes, you can use this calculator to estimate your new monthly payment when refinancing. Simply enter your current loan balance, new interest rate, and loan term.
What's the difference between APR and interest rate?: The interest rate is the cost of borrowing, while the APR includes all loan costs and fees. The APR is typically higher than the interest rate because it accounts for all financing costs.
How does a down payment affect my loan?: A larger down payment reduces your loan amount and can lower your monthly payments. It also typically results in better loan terms and lower interest rates.
What if I want to pay extra each month?: If you make additional payments, your loan will be paid off faster, and you'll save on interest. You can use our extra payment calculator to see how much you'll save.
