A common guideline is to keep all your car costs (payment, insurance, fuel, maintenance, parking and registration) at or below about 15% of your take-home pay, with the loan payment itself around 10% or less. On a take-home income of $5,000 per month, that means roughly $500 for the payment and $750 in total car costs. Your real limit depends on your other debts, savings and where you live.

Start with your take-home pay, not your salary
Use the amount that actually lands in your bank account each month, after income tax, CPP or QPP contributions and EI premiums. Budgeting on gross salary is the most common way people overspend on a car.
Rules of thumb
| Rule | What it says | Why it helps |
|---|---|---|
| 10% payment rule | Car payment no more than about 10% of take-home pay | Leaves room for insurance and fuel |
| 15% total cost rule | All car costs no more than about 15% of take-home pay | Reflects the real cost of owning a car |
| 20/4/10 (adapted) | 20% down, loan of about four to five years, total costs about 10 to 15% of take-home pay | Limits interest and negative equity |
These are guidelines, not laws. If you have high rent, child care costs or other debt, aim lower.
Example budgets
| Monthly take-home pay | Target payment (10%) | Total car costs (15%) |
|---|---|---|
| $3,000 | $300 | $450 |
| $4,000 | $400 | $600 |
| $5,000 | $500 | $750 |
| $6,500 | $650 | $975 |
| $8,000 | $800 | $1,200 |
Turn a payment into a car price
A payment of $500 per month at 7.99% over 60 months supports a loan of roughly $24,700. Add your down payment and trade-in, and remember that sales tax is part of what you finance. If your province charges 13% tax, a $24,700 loan plus a $3,000 down payment covers a vehicle price of only about $24,500 before tax. Test your own numbers with the car payment calculator.
Don’t forget the costs beyond the payment
- Insurance: varies widely by province, city, age, driving record and vehicle. Get quotes before you buy, not after. See how to compare car insurance quotes.
- Fuel or electricity: multiply your yearly kilometres by the vehicle’s consumption. A car using 8 L/100 km driven 15,000 km per year needs about 1,200 litres of fuel.
- Maintenance and repairs: oil changes, tires, brakes and unexpected repairs. Older cars cost less to buy and more to maintain. Read average car maintenance costs in Canada.
- Winter tires: a set of winter tires and rims is a real expense in most of Canada.
- Registration, parking and tolls.
- Depreciation: not a monthly bill, but the biggest cost of a new car in its first years.

A step-by-step budget
- Write down your monthly take-home pay.
- Subtract fixed costs (housing, debt payments, child care, savings).
- Get insurance quotes for the models you are considering.
- Estimate fuel or charging and maintenance.
- What is left, within the 10% guideline, is your maximum payment.
- Get pre-approved by your bank or credit union so you know your real rate.
- Shop by total price, not by monthly payment.
Ways to afford a better car without overspending
- Buy a two- to four-year-old vehicle instead of new to avoid the steepest depreciation.
- Increase your down payment.
- Choose a reliable, less expensive model to insure and repair. See the most reliable used cars in Canada.
- Improve your credit score before applying for a loan.
Frequently asked questions
What percentage of income should go to a car payment?
A common guideline is no more than about 10% of take-home pay for the payment and about 15% for all car costs combined.
Is an 84-month car loan a bad idea?
It lowers the payment but increases total interest and the risk of owing more than the car is worth. It can work for a reliable car you will keep for a long time, but shorter terms are safer.
Should I include insurance in my car budget?
Yes. In some provinces and cities, insurance can cost almost as much as the payment, especially for young drivers. Get quotes before choosing a vehicle.
