Formula Used

The auto loan payment calculator uses the standard 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 years × 12)

This formula calculates the fixed monthly payment required to pay off a loan with the given terms.

Worked Example

Let's calculate a monthly payment for a $25,000 loan at 5% annual interest over 5 years:

Principal (P) = $25,000
Annual interest rate = 5% or 0.05
Monthly interest rate (r) = 0.05 / 12 ≈ 0.004167
Number of payments (n) = 5 × 12 = 60

Plugging these values into the formula:

Monthly Payment = $25,000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)

Monthly Payment ≈ $462.35

For this example, the total interest paid would be approximately $3,750, and the total amount paid would be $28,750.

Frequently Asked Questions

What is an auto loan payment?

An auto loan payment is the monthly amount you pay to your lender to repay your auto loan. This payment typically includes both principal (the amount you're borrowing) and interest (the cost of borrowing).

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. Conversely, a lower interest rate will result in lower monthly payments.

Can I pay off my auto loan early?

Yes, you can pay off your auto loan early, but it's important to check your loan agreement for any prepayment penalties. Some loans allow early repayment without penalties, while others may charge fees for paying off the loan before the agreed-upon term.
