Formula Used

The calculator uses the standard auto 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 multiplied by 12)

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

Worked Example

Let's calculate a $25,000 auto loan with a 4.5% annual interest rate over 5 years:

Principal (P) = $25,000
Annual interest rate = 4.5% or 0.045
Monthly interest rate (r) = 0.045 / 12 ≈ 0.003792
Number of payments (n) = 5 years × 12 = 60 months

Plugging these values into the formula:

Monthly Payment = $25,000 * (0.003792(1 + 0.003792)^60) / ((1 + 0.003792)^60 - 1)

Monthly Payment ≈ $454.23

Total interest paid over 5 years would be approximately $3,261.80.

Frequently Asked Questions

What is the difference between APR and interest rate?

APR (Annual Percentage Rate) is the total annual cost of borrowing, including fees, while the interest rate is the portion of APR that represents the actual cost of borrowing. APR is always higher than the interest rate.

How does loan term affect my monthly payment?

A longer loan term means lower monthly payments but more total interest paid. A shorter loan term means higher monthly payments but less total interest paid. Choose a term that fits your budget and financial goals.

What happens if I make extra payments?

Making extra payments can reduce your principal balance faster, lower your total interest, and potentially shorten your loan term. However, check with your lender to ensure they allow extra payments and understand how they affect your loan.
