Calculate an Ontario mortgage payment using Canadian semi-annual compounding, then compare affordability, stress-test, land-transfer-tax, renewal and rate scenarios in one place. Results are estimates, not approval or a lender offer.
Calculations use Canadian semi-annual compounding as required by the Interest Act. CMHC premiums apply when down payment is less than 20%. Rates shown for illustrative purposes.
Based on OSFI's GDS/TDS qualifying ratios for Ontario buyers.
Estimates based on standard GDS (39%) and TDS (44%) ratios. Actual qualification may vary by lender, credit score, and other factors. Stress test qualifying rate = contract rate + 2% or 5.25%, whichever is higher.
The stress test determines if you can still afford your mortgage if interest rates rise.
