Car Loan Cost Calculator


The Car Loan Cost Calculator is a handy tool for estimating the monthly payments on your car loan. By providing the loan amount, annual interest rate, and loan term, you can get an idea of your financial commitment before making a car purchase.


The monthly payment is calculated using the following formula: Monthly Payment=�×(�×(1+�)�)(1+�)�−1Monthly Payment=(1+r)n−1P×(r×(1+r)n)​ Where:

  • P is the loan amount,
  • r is the monthly interest rate (annual interest rate divided by 12 and converted to a decimal), and
  • n is the total number of payments (loan term in years multiplied by 12).

How to Use

  1. Enter the loan amount you are considering.
  2. Input the annual interest rate (in percentage).
  3. Specify the loan term in years.
  4. Click the “Calculate” button to get the estimated monthly payment.


Suppose you are taking out a car loan of $20,000 with an annual interest rate of 5% and a loan term of 3 years. The estimated monthly payment would be calculated as follows: Monthly Payment=20000×(0.05/12×(1+0.05/12)3×12)(1+0.05/12)3×12−1Monthly Payment=(1+0.05/12)3×12−120000×(0.05/12×(1+0.05/12)3×12)​
