Monthly Auto Loan Calculator


Purchasing a car often involves financing through an auto loan, and understanding the financial implications is crucial. The Monthly Auto Loan Calculator is a helpful tool that allows individuals to estimate their monthly loan payments accurately, aiding in budgeting and financial planning.


The formula for calculating monthly auto loan payments is typically based on the loan amount, interest rate, and loan term. The formula is as follows:

Monthly Payment=Loan Amount×Monthly Interest Rate1−(1+Monthly Interest Rate)−Number of Monthly Payments 

Here, the Monthly Interest Rate is the annual interest rate divided by 12, and the Number of Monthly Payments is the total number of monthly installments over the loan term.

How to Use?

Using the Monthly Auto Loan Calculator is a straightforward process:

  1. Input Loan Amount: Enter the total amount of the auto loan you are considering.
  2. Specify Interest Rate: Input the annual interest rate offered by the lender.
  3. Enter Loan Term: Specify the number of months over which you plan to repay the loan.
  4. Calculate: Press the calculate button to obtain your estimated monthly auto loan payment.


Consider an example:

  • Loan Amount: $20,000
  • Annual Interest Rate: 5%
  • Loan Term: 48 months

Using the formula:

Monthly Interest Rate=5%12=0.004167

Monthly Payment=$20,000×0.0041671−(1+0.004167)−48

After calculation, the estimated monthly auto loan payment would be $460.77.
