Consider saving for a 20% down payment to avoid negative equity risk.
The 20/4/10 rule is widely considered outdated - RateHub.ca and Driving.ca recommend 15–20% of take-home as the realistic benchmark for most Canadians in 2026.

The 20/4/10 rule is the classic Canadian guideline for buying a car without becoming car-poor: 20% minimum down payment, 4 years maximum financing term, and total transportation costs (loan payment + insurance + fuel + maintenance) under 10% of your gross monthly income. This calculator checks all three at once and tells you the maximum vehicle price you can comfortably afford.
The tool solves for the vehicle price where: down payment = 20% of price, loan term = 48 months at current rate, and (monthly loan payment + insurance + fuel + maintenance) ≤ 10% of your gross monthly income. It uses province-specific insurance and fuel assumptions you can adjust.
Average Canadian new-car price in April 2026 is around $68,000 - 2× the pre-pandemic average. A household earning $120,000/year gross can safely afford roughly $1,000/month in total transport spend, which translates to a $28,000–$35,000 vehicle depending on province.
The 20/4/10 rule recommends putting at least 20% down, financing for no longer than 4 years, and keeping total vehicle costs (payment, insurance, gas) under 10% of gross monthly income. It is a widely used guideline to avoid being car-poor.
Financial planners generally suggest keeping your total vehicle payment plus insurance under 10–15% of your take-home pay. For a household earning $80,000 net, that is roughly $650–$1,000 per month. Use the affordability calculator to find your number based on your actual income and province.
New vehicles offer warranties and the latest safety features but depreciate 15–25% in the first year. Used vehicles lose less value immediately and often cost less to insure. The 20/4/10 rule applies to both; the calculator can compare the budget impact of different price points.
