Car Affordability Calculator


Calculating car affordability is an essential step when planning to purchase a vehicle. To streamline this process, a car affordability calculator proves to be invaluable. With this tool, individuals can assess their financial capabilities and determine the suitable budget for their desired car.

How to Use

Using the car affordability calculator is straightforward. Simply input your financial details into the designated fields, including your desired loan term, interest rate, and down payment. Once all necessary information is provided, click the “Calculate” button to obtain the monthly payment amount you can afford.


The formula used in the car affordability calculator is based on the standard formula for calculating loan payments, also known as the amortization formula. This formula calculates the monthly payment amount based on the principal loan amount, interest rate, and loan term. The formula is as follows:


  • M = Monthly payment
  • P = Principal loan amount
  • r = Monthly interest rate (annual interest rate divided by 12)
  • n = Total number of payments (loan term in months)

Example Solve

Let’s consider an example where:

  • Principal loan amount (P) = $25,000
  • Annual interest rate = 5%
  • Loan term = 60 months (5 years)

First, calculate the monthly interest rate (r):

Next, calculate the total number of payments (n):


Now, substitute the values into the formula:

After calculation, the monthly payment (M) would be approximately $471.78.
