Buying a car is a significant financial decision. Understanding how much car you can realistically afford helps prevent overextending your budget and getting stuck with unaffordable payments. The Car Affordability Calculator estimates the maximum car price you can afford by considering your income, existing debt payments, down payment, loan term, and interest rate.

Formula

• Maximum Monthly Car Payment = (Monthly Gross Income × 15%) – Existing Monthly Debt Payments
• Loan Amount (P) = Monthly Payment × [(1 + r)^n – 1] ÷ [r(1 + r)^n], where r = monthly interest rate, n = loan term in months
• Maximum Car Price = Loan Amount + Down Payment

Example

Suppose your annual income is $60,000, monthly debts are $500, down payment $5,000, loan term 60 months, and interest rate 5% annually:

• Monthly income = 60,000 ÷ 12 = $5,000
• Max monthly payment = (5,000 × 15%) – 500 = 750 – 500 = $250
• Calculate loan amount with monthly payment $250 over 60 months at 5% interest → approx. $13,715
• Add down payment → max car price ≈ $18,715
