Car Affordability Calculator FullScreen

Use our free online Car Affordability Calculator to calculate how much you can spend on a car. Additionally, the calculator takes into account interest rates, trade-ins, sales taxes, down payments, and loan terms to create a loan amortization schedule.

How much car can I afford?



To calculate the loan amount we use the following formula:

P = (A / Rate) × [ 1 − (1 + Rate) − N ]


P = The loan amount ,

A = The monthly loan payment ,

N = The number of monthly payments (for a 3 year loan N = 3 x 12 = 36) ,

Rate (monthly interest rate) = Decimal Rate / 12 , or Rate = (Annual Interest Rate / 100) / 12.

What is Car Affordability Calculator

A Car Affordability Calculator is a financial tool used to determine how much you can afford to spend on purchasing a car. It helps individuals assess their budget and financial situation to determine a reasonable price range for buying a car without straining their finances.

Here's how a typical Car Affordability Calculator works:

  1. Monthly Income: You input your monthly income, which can include salaries, wages, and any other regular sources of income.

  2. Monthly Expenses: The calculator allows you to input your monthly expenses, such as rent/mortgage, utilities, groceries, insurance, debt payments, and other recurring bills.

  3. Down Payment: You specify the amount of money you plan to contribute as a down payment towards the purchase of the car. A higher down payment reduces the loan amount and monthly payments.

  4. Loan Term: You select the desired duration or time period over which you want to repay the car loan. Common terms are usually 36, 48, or 60 months.

  5. Interest Rate: The calculator allows you to input the estimated interest rate for the car loan. This rate determines the cost of borrowing and influences the total interest paid.

  6. Calculation: Using the provided inputs, the Car Affordability Calculator calculates the maximum monthly payment you can comfortably afford. It takes into account your income, expenses, down payment, loan term, and interest rate to determine the affordable monthly payment.

  7. Displaying the Result: The calculator presents the calculated maximum monthly payment amount and provides an estimated price range for purchasing a car based on this payment.

The Car Affordability Calculator helps individuals set realistic expectations and make informed decisions about their car purchase. It ensures that the monthly payment fits within their budget and prevents them from overextending their finances.

It's important to note that the calculated results are estimates based on the provided inputs and assumptions. Actual loan terms, interest rates, and vehicle prices may vary depending on factors such as creditworthiness, lender policies, fees, and other specific terms. Therefore, it's advisable to consult with a qualified financial advisor or lender for accurate and personalized information regarding car affordability calculations and loan options.

Car Affordability Calculator Example

Sure! Here's an example of a Car Affordability Calculator that helps determine how much car you can afford based on your monthly income and expenses:

Let's assume the following financial information: Monthly Income: $4,000 Monthly Expenses: $1,500 Target Savings Rate: 20% (optional)

To calculate the maximum amount you can afford to spend on a car, we need to consider your monthly income, expenses, and desired savings rate.

Step 1: Calculate the Available Income Available Income = Monthly Income - Monthly Expenses

Available Income = $4,000 - $1,500 = $2,500

Step 2: Determine the Maximum Monthly Car Payment Maximum Monthly Car Payment = Available Income * Car Expense Ratio

The Car Expense Ratio typically ranges from 10% to 20% of your available income. For this example, let's assume a Car Expense Ratio of 15%.

Maximum Monthly Car Payment = $2,500 * 0.15 = $375

Step 3: Calculate the Maximum Affordable Car Loan To calculate the maximum affordable car loan, we need to consider the interest rate and loan term. Let's assume an interest rate of 4% and a loan term of 5 years (60 months).

Maximum Affordable Car Loan = Maximum Monthly Car Payment * (1 - (1 + Monthly Interest Rate) ^ (-Loan Term))) / Monthly Interest Rate

Monthly Interest Rate = Annual Interest Rate / 12 = 4% / 12 = 0.3333%

Maximum Affordable Car Loan = $375 * (1 - (1 + 0.003333) ^ (-60)) / 0.003333

Maximum Affordable Car Loan = $21,261.07

Therefore, based on a monthly income of $4,000, monthly expenses of $1,500, and a target savings rate of 20%, you can afford a maximum car loan of approximately $21,261.07.

Please note that this is just an example calculation, and actual affordability may vary depending on individual financial circumstances. Additionally, it's important to consider other factors such as down payment, insurance costs, and ongoing maintenance expenses when budgeting for a car purchase.
