Car Affordability Rules of Thumb

The 10-15% Rule:

• Conservative: 10% of monthly income for car payment
• Moderate (Recommended): 15% of monthly income for car payment
• Aggressive: 20% of monthly income for car payment

The 20/4/10 Rule:

• 20% down payment
• 4 years loan term maximum
• 10% of monthly income for transportation

The 35% Rule:

• Total transportation costs (payment, insurance, gas, maintenance) should not exceed 35% of income

Affordability by Income Level

Assuming 15% of income for car payment, 20% down, 60-month term at 7.5% APR:

Monthly Income	Car Payment	Max Car Price
$2,500	$375	$17,500
$3,000	$450	$21,000
$4,000	$600	$28,000
$5,000	$750	$35,000
$6,000	$900	$42,000
$8,000	$1,200	$56,000
$10,000	$1,500	$70,000

Don't Forget Hidden Costs

Ongoing Car Ownership Costs:

• Insurance: $100-300/month depending on vehicle and location
• Fuel: $100-300/month depending on commute and MPG
• Maintenance: $50-150/month average
• Registration/Taxes: $200-500/year
• Parking: $50-200/month in some areas

Real Monthly Transportation Cost Example:

Car Payment: $500
Insurance: $150
Fuel: $150
Maintenance: $75
Total: $875/month

Debt-to-Income Ratio (DTI)

Lenders look at your DTI ratio to determine loan eligibility:

DTI = Total Monthly Debt Payments / Monthly Income

• Below 36%: Excellent - Best loan terms
• 36-43%: Good - Qualification likely
• 43-50%: Fair - May qualify with restrictions
• Above 50%: Poor - Difficult to qualify

Your new car payment will increase your DTI. Keep this in mind when deciding how much to spend.

Tips for Buying Within Your Budget

Before You Shop:

• Check your credit score and fix errors
• Get pre-approved for a loan
• Calculate your total transportation budget
• Research reliable vehicles within your price range

At the Dealership:

• Focus on total price, not monthly payment
• Negotiate the price first, then financing
• Avoid expensive add-ons and extended warranties
• Consider certified pre-owned instead of new

Save Money By:

• Buying used vs. new (20-30% depreciation in first year)
• Buying older models (1-3 years old)
• Shopping at end of month/quarter/year
• Considering less popular makes/models
• Buying from private sellers (with caution)
