How Much Car Can I Afford?
Before you start shopping, figure out how much car you can actually afford. Here's a practical guide to setting your car budget in Canada.
The most common mistake car buyers make is shopping for a car before knowing what they can afford. Here's how to figure out your car budget in Canada.
The 20/4/10 rule
A widely used guideline for car affordability:
- 20% down: Put at least 20% down to reduce your loan and avoid being underwater
- 4-year term: Keep the loan to 48 months or less to minimize interest
- 10% of gross income: Your total monthly car cost (payment + insurance + gas + maintenance) shouldn't exceed 10% of your gross monthly income
This is a conservative rule. Many Canadians stretch beyond it, but doing so increases financial risk.
A more practical approach
Let's say you make $60,000/year ($5,000/month gross). Here's how the math works:
10% rule: $500/month total car cost
- Insurance: ~$150/month
- Gas: ~$200/month
- Maintenance: ~$50/month
- Remaining for payment: ~$100/month — which only finances about $5,000–$6,000
That's very conservative. Most Canadians spend 15–20% of gross income on transportation. At 15% ($750/month), subtracting $400 for insurance, gas, and maintenance leaves $350 for a car payment — enough to finance about $18,000–$20,000 over 60 months at 6%.
Total cost of ownership
Don't just budget for the payment. A car costs:
| Expense | Monthly Estimate |
|---|---|
| Loan payment | $300–$600 |
| Insurance | $120–$300 |
| Fuel | $150–$300 |
| Maintenance | $50–$150 |
| Registration | $10–$20 |
| Total | $630–$1,370 |
Factors that affect affordability
- Your income: Higher income = more room, but don't let lifestyle creep push you into too much car
- Existing debt: Student loans, credit cards, and other payments reduce what you can spend
- Housing costs: High rent or mortgage means less for a car
- Down payment: More down = smaller loan = lower payment
- Credit score: Better score = lower rate = lower payment for the same car
Signs you're buying too much car
- The payment is more than one week's take-home pay
- You need a loan longer than 72 months to afford the payment
- You can't afford a 20% down payment
- You'd have to skip other financial goals (savings, debt repayment) to afford it
- You're counting on overtime or bonuses to make the payment
Quick affordability calculator
- Calculate your monthly gross income
- Multiply by 0.15 (15% rule) — this is your total car budget
- Subtract $350 for insurance, gas, and maintenance
- The remainder is your maximum monthly payment
- At 6% interest over 60 months, multiply the payment by 50 to get your max loan amount
Example: $5,000/month gross × 0.15 = $750 − $350 = $400 payment × 50 = $20,000 max loan
