Formula Explained

The auto loan payment calculation uses the standard loan payment formula:

Loan Payment Formula

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (APR/12/100)
n = Number of payments (loan term in months)

This formula calculates the fixed monthly payment required to pay off the loan in the specified term, including both principal and interest.

Worked Example

Let's calculate a loan with these parameters:

Loan amount: $25,000
Annual interest rate: 5%
Loan term: 60 months

Using the formula:

Calculation Steps

1. Convert annual rate to monthly: 5%/12 = 0.4167% or 0.004167

2. Plug values into formula: 25000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)

3. Calculate: Monthly payment ≈ $452.34

4. Total interest paid: $1,727.40

5. Total cost of loan: $26,727.40

This example shows that with a $25,000 loan at 5% APR over 5 years, you would pay approximately $452.34 per month, with $1,727.40 going to interest.

Frequently Asked Questions

What is an auto loan APR?

APR stands for Annual Percentage Rate. It represents the annual cost of borrowing, including both the interest rate and any fees. A lower APR means lower monthly payments and less total interest paid over the life of the loan.

How does loan term affect my payments?

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

What's the difference between APR and interest rate?

The interest rate is the cost of borrowing without fees, while APR includes all fees and costs. APR is always higher than the interest rate and gives a more accurate picture of the total cost of borrowing.
