What is the Stress Test?

Canadian lenders (OSFI B-20) must qualify you at a higher rate than your contract rate, to ensure you can still afford payments if rates rise.

▸GDS (Gross Debt Service) ≤ 39%: Your housing costs (mortgage P+I, property tax, heating, condo fees) divided by your gross income.
▸TDS (Total Debt Service) ≤ 44%: Same as GDS, plus all other debt payments (car loans, student loans, credit cards).
▸Both ratios use the qualifying rate, not your actual rate - this is the stress test. If you pass at the higher rate, you qualify.
▸Stress test applies to new purchases and refinances, but NOT renewals with the same lender.

About this calculator

Updated November 2026

The Canadian mortgage calculator shows monthly payments, amortization schedule, and total interest cost for any home price, down payment, and rate - with the OSFI stress test built in. It supports all provinces for land-transfer tax and layers CMHC default insurance automatically when your down payment is below 20%.

What you can do with it

  • Compare fixed vs variable rates side-by-side with total interest projections.
  • See how an extra $100/month or lump-sum prepayment shortens your amortization.
  • Model what happens at renewal if rates stay flat, drop 1%, or rise 2%.
  • Estimate total cash-to-close including land-transfer tax and legal fees.
  • Tick "first-time buyer" to plan FHSA + RRSP Home Buyers' Plan savings toward your down payment.

How the math works

Payments use the standard Canadian mortgage formula with semi-annual compounding for fixed-rate mortgages (monthly for variable). The stress test qualifies you at the greater of your contract rate + 2% or the 5.25% benchmark floor. CMHC premiums range from 2.80% at 15–19.99% down to 4.00% at 5–9.99% down, added to principal. First-time buyer rebates are reflected in the province-specific land-transfer tax calculations.

Canadian context - 2026

A 25-year amortization is the maximum for standard insured mortgages; 30-year insured is available for first-time buyers or buyers of newly built homes via CMHC Home Start. Following the Bank of Canada's 25 bps rate increase on October 28, 2026, the prime rate is 4.70% (policy rate 2.50%) - verify current lender rates before locking in.

Frequently asked questions

What is the mortgage stress test in Canada?

Federal rules require lenders to qualify borrowers at a higher rate than your contract rate (or a minimum floor), to ensure payments remain affordable if rates rise. The calculator can illustrate stress-tested payments for planning.

How does buy vs rent work here?

The tool compares the long-term cost of owning (including mortgage, taxes, insurance, and opportunity cost of a down payment) with renting, using assumptions you enter. Results depend heavily on those inputs.

Are CMHC premiums included?

When applicable, mortgage default insurance premiums can be modeled so you see their effect on payments and total cost. Actual lender rules may differ.

How does the RRSP Home Buyers' Plan work?

The HBP lets first-time buyers withdraw up to $60,000 from their RRSP tax-free to buy or build a qualifying home. The withdrawn amount must be repaid to your RRSP over 15 years; any unpaid portion is added to taxable income each year. Tick "first-time buyer" in the calculator to plan your down payment savings.

Can I combine FHSA and RRSP HBP for a down payment?

Yes. A single buyer can use up to $40,000 from an FHSA plus up to $60,000 from the RRSP HBP, for up to $100,000 of tax-advantaged down payment. A couple can access up to $200,000 combined. FHSA withdrawals require no repayment; HBP withdrawals must be repaid over 15 years.
