Buying a car is exciting, but knowing how much you can realistically afford is essential to avoid financial strain. The Auto Loan Affordability Calculator helps you estimate your recommended monthly payment, maximum loan amount, total interest, and maximum vehicle price based on your income, expenses, and loan terms.

This tool is perfect for anyone planning a car purchase, whether it’s your first vehicle or an upgrade. By entering your monthly income, expenses, interest rate, down payment, and loan term, you can quickly determine what you can comfortably spend.

How the Auto Loan Affordability Calculator Works

The calculator uses a simple formula to ensure your car payment fits your budget:

  1. Monthly Income: Your total earnings per month.
  2. Monthly Expenses: Rent, bills, groceries, and other fixed costs.
  3. Interest Rate (%): Annual interest rate on the car loan.
  4. Loan Term: Duration of the loan in years (3–7 years).
  5. Down Payment: Initial payment you can make upfront.

From these inputs, the calculator provides:

  • Recommended Monthly Payment: Suggested amount based on 28% of your disposable income (income minus expenses).
  • Maximum Affordable Loan Amount: Loan you can afford with the recommended monthly payment.
  • Maximum Vehicle Price: Total car price including your down payment.
  • Total Interest Paid: Estimated interest you’ll pay over the loan term.

  5. Enter your down payment, if any.

Example Calculation

Inputs:

  • Monthly Income: $4,500
  • Monthly Expenses: $2,000
  • Interest Rate: 5%
  • Loan Term: 5 years
  • Down Payment: $3,000

Step 1: Disposable Income

  • Disposable Income = 4,500 – 2,000 = $2,500

Step 2: Recommended Monthly Payment

  • Recommended Payment = 28% of disposable income = 2,500 × 0.28 = $700

Step 3: Maximum Loan Amount

  • Using the loan formula, the max loan ≈ $35,800

Step 4: Maximum Vehicle Price

  • Max Vehicle Price = Max Loan + Down Payment = 35,800 + 3,000 = $38,800

Step 5: Total Interest Paid

  • Total Interest = (700 × 60 months) – 35,800 ≈ $6,200

This calculator gives a clear picture of what you can afford without overextending your budget.
