Find out how much home you can afford based on your income, debts, and down payment using Canadian lending rules and GDS/TDS ratios.
Use our free Canadian home affordability calculator to determine how much house you can afford based on your income, debts, and down payment. This calculator applies the GDS and TDS ratios used by Canadian lenders along with the federal mortgage stress test to give you a realistic picture of your maximum purchase price in BC.
Canadian lenders use two key ratios to determine how much mortgage you qualify for:
The more restrictive of these two ratios determines your maximum borrowing capacity. For example, if your GDS allows a $3,500 mortgage payment but your TDS (due to existing debts) only allows $3,000, the lender will use the $3,000 figure.
Since 2018, all federally regulated lenders in Canada require borrowers to qualify at a stress test rate, which is the higher of:
This means even if your actual mortgage rate is 4.5%, you must qualify as if it were 6.5%. The stress test is designed to ensure you can still afford your payments if interest rates rise. This calculator automatically applies the stress test to your affordability estimate.
Here are some general guidelines based on annual household income with a 20% down payment, 25-year amortization, and typical debt levels:
| Annual Income | Approx. Max Purchase Price | Monthly Payment (est.) |
|---|---|---|
| $60,000 | $280,000 - $320,000 | $1,250 - $1,450 |
| $80,000 | $380,000 - $440,000 | $1,700 - $1,950 |
| $100,000 | $480,000 - $560,000 | $2,100 - $2,450 |
| $120,000 | $580,000 - $680,000 | $2,550 - $2,950 |
| $150,000 | $730,000 - $850,000 | $3,200 - $3,700 |
| $200,000 | $980,000 - $1,150,000 | $4,300 - $5,000 |
Estimates assume 5.5% interest rate, 25-year amortization, $500/month in other debts, and 20% down payment. Actual amounts vary by lender and individual financial situation.
Reducing monthly debt payments lowers your TDS ratio, allowing you to qualify for a larger mortgage. Focus on high-interest debts first.
A bigger down payment means a smaller mortgage, lower monthly payments, and potentially avoiding CMHC insurance premiums.
Combining household incomes significantly increases your borrowing capacity. Two incomes of $70,000 qualify for far more than one income of $70,000.
Choosing a 30-year amortization (requires 20%+ down) lowers monthly payments and may increase the home price you qualify for.
Programs like the FHSA, HBP (RRSP withdrawal), and BC first-time buyer PTT exemption can help boost your budget.
A higher credit score can qualify you for better mortgage rates, effectively increasing how much home you can afford over the life of the loan.

Income required depends on the home price, down payment, interest rates, and property taxes. As a general benchmark, you need gross household income of approximately 20-25% of the purchase price. For a $800,000 home in Surrey or Langley, expect to need $160,000-$200,000 household income. However, this assumes 20% down; with 5% down and CMHC insurance, you'd need slightly higher income to pass debt ratio tests. The current stress test (qualifying at 5.25% benchmark) typically requires income of 30-35% of purchase price. Use our calculator above to determine your exact affordability based on your specific income, debts, and down payment savings.
GDS (Gross Debt Service) ratio cannot exceed 39%, meaning your housing costs (mortgage, property tax, insurance, strata fees) shouldn't exceed 39% of gross household income. TDS (Total Debt Service) ratio cannot exceed 44%, including all debts—mortgage, property tax, insurance, strata fees, car loans, credit cards, and student loans. These ratios protect both you and lenders. On $200,000 household income, maximum GDS housing costs would be $78,000 annually ($6,500/month), and maximum total debts including housing would be $88,000 annually ($7,333/month). With current interest rates and stress testing, most buyers qualify for less than the maximum ratios allow. Our affordability calculator uses these exact ratios to give you accurate borrowing capacity.
For homes under $500,000, minimum down payment is 5% of the purchase price. For homes between $500,000-$999,999, you need 5% on the first $500,000 plus 10% on the remainder. For homes $1,000,000 and above, minimum down payment is 20%. CMHC insurance is required for down payments under 20%, adding 0.6%-4.5% to your mortgage depending on loan-to-value ratio. In hot markets like Metro Vancouver and Surrey, many buyers put down 10-15% to avoid maximum CMHC insurance costs. First-time buyers benefit from gifts from family (up to 100% allowed from parents), which don't require repayment—a popular strategy in BC real estate.
Yes, co-buying with family or friends can improve affordability by combining incomes for qualification and splitting down payment savings. Both co-owners appear on title and the mortgage, combining their debt ratios for lending purposes. A $300,000 joint household income qualifies for significantly higher mortgage than $150,000 individual income. Important considerations: joint ownership affects future refinancing, selling, and estate planning; both parties are equally liable for the entire mortgage; and relationship changes complicate ownership. Consult a lawyer about tenancy options (joint tenancy vs. tenancy-in-common) and consider written co-ownership agreements. This strategy is increasingly common in BC's expensive markets among siblings, parents-adult children, and committed couples.
The Fraser Valley offers significantly better affordability than Metro Vancouver—typical homes in Abbotsford range $550,000-$700,000 compared to $900,000+ in Surrey. Chilliwack, Mission, and Maple Ridge are other affordable options with 30-minute to one-hour commutes to downtown Vancouver. South of the border, parts of Langley and Aldergrove offer value. In Metro Vancouver, affordability increases with distance from Vancouver: North Delta, Burnaby, and Port Coquitlam offer better entry prices than West Vancouver or Vancouver proper. However, affordability should balance with lifestyle and commute time—a $500,000 home 90 minutes from work costs differently in total cost-of-living. I specialize in helping buyers find value throughout the Fraser Valley and Metro Vancouver, matching neighbourhood affordability with lifestyle preferences and income stability.
