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
  • i = Monthly interest rate (annual rate divided by 12)
  • n = Number of payments (loan term in years multiplied by 12)

Total interest paid is calculated by subtracting the principal loan amount from the total of all monthly payments.

Worked Example

Let's calculate a $20,000 auto loan with a 5% annual interest rate over 4 years (48 months):

Input Value
Loan Amount $20,000
Interest Rate 5%
Loan Term 4 years

Using the formula:

Calculation Steps

Monthly interest rate = 5% / 12 = 0.4167%

Number of payments = 4 years × 12 = 48 months

Monthly payment = $20,000 [ 0.004167(1 + 0.004167)^48 ] / [ (1 + 0.004167)^48 - 1 ]

Monthly payment ≈ $432.88

Total payments = $432.88 × 48 ≈ $20,750.88

Total interest = $20,750.88 - $20,000 = $750.88

For this example, your monthly payment would be approximately $432.88, with a total interest of $750.88 over the life of the loan.

Frequently Asked Questions

What is an auto loan payoff?
An auto loan payoff is the total amount you need to pay back to the lender to fully pay off your auto loan, including both the principal amount and the accumulated interest.
How does the interest rate affect my monthly payments?
A higher interest rate will result in higher monthly payments and a larger total interest paid over the life of the loan. Conversely, a lower interest rate will reduce your monthly payments and the total interest paid.
Can I pay off my auto loan early?
Yes, you can pay off your auto loan early without penalty in most cases. Paying early can save you money on interest and help you build equity in your vehicle faster.
What happens if I miss a payment?
Missing a payment can result in late fees, higher interest charges, and potentially damage your credit score. It's important to make your payments on time to avoid these consequences.
Can I refinance my auto loan?
Yes, refinancing your auto loan can help you secure a lower interest rate, reduce your monthly payments, and save on interest over time. However, it's important to consider the costs and terms of refinancing before proceeding.
