Formula Explained

The monthly payment for an auto loan is calculated using the standard loan payment formula:

Loan 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 (loan term in years × 12)

For a 6-year loan (72 months), the formula becomes:

6-Year Loan Payment Formula

M = P [ i(1 + i)^72 ] / [ (1 + i)^72 - 1 ]

The calculator uses this formula to determine your monthly payment based on the inputs you provide.

Worked Example

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

Loan amount: $25,000
Annual interest rate: 4.5%
Down payment: $2,500
Loan term: 6 years (72 months)

First, calculate the principal amount:

Principal Calculation

Principal = Loan amount - Down payment

Principal = $25,000 - $2,500 = $22,500

Next, calculate the monthly interest rate:

Monthly Interest Rate

Monthly rate = Annual rate / 12

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

Now apply the loan payment formula:

Monthly Payment Calculation

M = $22,500 [ (0.00375)(1 + 0.00375)^72 ] / [ (1 + 0.00375)^72 - 1 ]

M ≈ $22,500 [ 0.00375 × 1.324 ] / [ 1.324 - 1 ]

M ≈ $22,500 [ 0.00483 ] / 0.324

M ≈ $22,500 × 0.015 / 0.324

M ≈ $340.91

So, with these parameters, your monthly payment would be approximately $340.91.

Using the calculator with these inputs will give you the exact same result.

Frequently Asked Questions

What is a 6-year auto loan?: A 6-year auto loan is a car financing option that allows you to borrow money to purchase a vehicle and repay it over 6 years (72 months) with monthly payments.
How does the interest rate affect my monthly payment?: A higher interest rate will increase your monthly payment because you'll be paying more in interest over the life of the loan. The calculator shows how changes in the interest rate affect your payment amount.
Can I pay off my auto loan early?: Yes, you can pay off your auto loan early without penalty. Paying extra each month will reduce the total interest paid and save you money. The calculator can help you estimate how much you'll save by paying extra.
What happens if I can't make my monthly payment?: If you can't make your monthly payment, contact your lender immediately. They may offer options like loan modifications, payment plans, or forbearance. Missing payments can damage your credit score and may result in repossession of the vehicle.
