Get Exact Numbers — Free CallHow the Mortgage Payment Calculator Works
Your monthly mortgage payment depends on more than just the sticker price of a home. This calculator uses the same Canadian semi-annual compounding lenders use, and automatically adds CMHC mortgage insurance if your down payment is under 20%, so the number you see is a realistic estimate — not a rough guess.
Adjust the home price, down payment, interest rate and amortization to see how each one moves your payment, then use the results to plan your budget before you start shopping.
4 Steps to Your Results
The calculator checks your down payment percentage against the 20% threshold to determine whether CMHC mortgage insurance applies.
Type your exact rate or drag the slider — every fixed-rate quote in Canada is compounded semi-annually, which this tool applies automatically.
Pick 15, 20, 25 or 30 years. Longer amortizations lower your monthly payment but increase total interest paid.
See your estimated monthly payment, the CMHC premium (if any), your total mortgage amount, and total interest over the full amortization.
Take a $750,000 home with 20% down ($150,000), a 4.49% rate, and a 25-year amortization — the calculator’s starting example.
Because the down payment is exactly 20%, no CMHC insurance is required, so the mortgage stays at $600,000. At 4.49% over 25 years, that works out to an estimated monthly payment of $3,318, with total interest of $395,251 paid over the full amortization.
Drop the down payment to 10% on the same home and CMHC insurance kicks in, adding a premium to the loan and raising both the mortgage balance and the payment — try it in the calculator above to see the exact difference.
