How to Use This Calculator

Using the Google Payment Calculator for Auto Loan is simple:

Formula Explained

The auto loan payment calculation uses 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
  • i = 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 fully amortize the loan over the specified term. The calculator also computes the total interest paid by subtracting the original loan amount from the total of all monthly payments.

Worked Example

Let's look at an example to see how the calculator works:

Example Calculation

Loan Amount: $25,000

Annual Interest Rate: 5%

Loan Term: 5 years

Monthly Payment: $462.68

Total Interest Paid: $2,744.40

Total Cost of Loan: $27,744.40

In this example, a $25,000 loan at 5% interest over 5 years would result in monthly payments of $462.68. Over the life of the loan, you would pay $2,744.40 in interest, bringing the total cost to $27,744.40.

Frequently Asked Questions

What is the difference between APR and interest rate?
The annual percentage rate (APR) is the total cost of credit, including fees and interest, while the interest rate is just the 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 interest paid over time. A shorter term results in higher monthly payments but less total interest.
What is the loan-to-value ratio?
The loan-to-value ratio (LTV) is the amount you borrow compared to the car's value. It's calculated as (Loan Amount / Car Value) × 100%. Lenders often require a minimum LTV based on your credit score.
Can I pay extra toward my loan?
Yes, paying extra principal reduces the loan balance faster and saves on interest. Many lenders allow bi-weekly payments or extra payments without penalty.
