What is an Auto Loan?
An auto loan is a type of financing that allows you to purchase a new or used vehicle by borrowing money from a lender and repaying it over time, usually with interest. Auto loans are commonly used because most people don't have enough cash to pay for a car upfront. The car itself typically acts as collateral for the loan, making it easier to qualify compared to unsecured loans.

How is an Auto Loan Payment Calculated? (Formula Explained)
The standard formula for a fixed-rate auto loan payment is:
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (months)
This formula helps you understand how much you'll pay each month, including both principal and interest. It's widely used by banks, credit unions, and auto finance companies.
Example: Auto Loan Calculation Step-by-Step
Let's say Alex wants to buy a car with these details:
- Loan amount: $25,000
- Interest rate: 5%
- Loan term: 5 years
First, convert the interest rate to a monthly rate: 5% ÷ 12 ÷ 100 = 0.0041667
Total payments: 5 × 12 = 60
Plug into the formula:
Alex's estimated monthly payment is $471.78.
