How much car can I afford on my salary?

A common rule is to spend no more than 20% of your gross annual income on a vehicle. For a $60,000 salary, that's $12,000. Using DTI, your total auto costs (payment + insurance) should not exceed 15% of monthly gross income.

What is a good DTI for a car loan?

Lenders prefer a total debt-to-income ratio below 43%. For auto loans specifically, keeping monthly payment below 10-15% of gross income helps ensure you can comfortably afford the vehicle.

Should I include insurance and maintenance in my car budget?

Yes. The purchase price is only part of the cost. Insurance, fuel, maintenance and registration add up, which is why the 15% DTI method caps total monthly auto costs (payment plus insurance) rather than just the loan payment. Budget for the full picture, not just the sticker price.

How much should I put down on a car?

A common target is at least 20% down on a new car and 10% on a used car. A larger down payment lowers your monthly payment, reduces total interest, and helps you avoid negative equity (owing more than the car is worth) during the steep first-year depreciation.

Does a longer loan term let me afford a more expensive car?

A longer term (72 or 84 months) lowers the monthly payment, so it can appear to expand your budget. But you pay far more total interest and stay underwater longer. The affordable price it implies is misleading because the real cost of the car rises sharply.

How does my credit score affect what car I can afford?

Your credit score largely determines your interest rate. A lower rate means more of each payment goes to principal, so you can afford a higher price at the same monthly payment. A poor score raises the rate and shrinks your affordable price range.

Is the 20% rule based on gross or net income?

The 20% rule uses gross annual income (before taxes). Because your take-home pay is lower, treat the result as a ceiling rather than a target, and sanity-check the monthly payment against your actual net budget.

Car Affordability Calculator

How to use Car Affordability Calculator

The car affordability calculator tells you the maximum vehicle price you can safely consider based on your gross income and debt load, using two proven methods: the 20% annual-income rule and the 15% debt-to-income (DTI) method. See the recommended price range, maximum monthly payment, and how a down payment and loan terms affect what you can actually afford.

Enter your gross annual income.
Add any existing monthly debt payments (student loans, credit cards, etc.).
Enter your planned down payment.
Set the interest rate and loan term.
Review the recommended car price range from both methods.

The 20% income rule vs the 15% DTI method

The 20% rule suggests keeping total vehicle cost (price + taxes + fees) below 20% of gross annual income. The 15% DTI method limits your total monthly auto costs (payment + insurance) to 15% of gross monthly income. Both are conservative guidelines; the more restrictive result is the safer budget. Lenders typically approve up to 43% total DTI, but that leaves little financial cushion.

Car affordability by annual income (20% rule, 10% down, 60-mo at 7%)
Annual income	Max car price	Est. monthly payment	Recommended down
$40,000	~$8,000	~$158	~$2,400
$60,000	~$12,000	~$238	~$3,600
$80,000	~$16,000	~$317	~$4,800
$100,000	~$20,000	~$396	~$6,000
$150,000	~$30,000	~$594	~$9,000

Down payment, loan terms and total cost

A larger down payment reduces the amount financed, lowering both the monthly payment and total interest paid. Aim for at least 20% down to avoid being "underwater" (owing more than the car is worth) as depreciation accelerates in year one. Shorter loan terms (36–48 months) cost more monthly but far less in total interest than 72- or 84-month terms.

Worked examples

$60,000 income (20% rule)

Inputs: 20% × $60,000

Result: ≈ $12,000 total vehicle budget

$60,000 income (15% DTI method)

Inputs: 15% × ($60,000 ÷ 12)

Result: ≤ $750/mo for payment + insurance

$12k budget, 10% down, 60-mo @ 7%

Inputs: $1,200 down → finance $10,800

Result: ≈ $214/mo principal & interest
