How to read your National Bank of Canada mortgage payment
Your mortgage payment is driven by three numbers: the mortgage amount (purchase price minus down payment, plus the CMHC premium if you’re under 20% down), the interest rate, and the amortization. National Bank of Canada, like every Canadian lender, uses semi-annual compounding rather than the monthly compounding US calculators assume, so the effective annual cost is slightly below the stated rate — this calculator uses the exact Canadian convention so your number matches what National Bank of Canada quotes.
The two National Bank of Canada rate sheets
National Bank of Canada runs a posted/branch rate quoted to walk-in customers and a wholesale broker-channel rateavailable only through a licensed brokerage — usually 15-30 bps lower because the broker does the origination work National Bank of Canada would otherwise pay branch staff to do. You can’t access the broker rate by walking into a National Bank of Canada branch. The calculator shows your payment at both the broker-channel rate and National Bank of Canada’s posted rate (~6.79%) so the gap is concrete rather than abstract.
A worked example: a $750,000 home with 20% down
Take a $750,000 purchase with $150,000 down — a $600,000 mortgage, no CMHC premium because you’re at 20% down. At a broker-channel rate near today’s 5-year fixed over a 25-year amortization, the payment lands a little over $3,300 a month. Run the same $600,000 at National Bank of Canada’s posted ~6.79% and the payment jumps by roughly $700 a month — about $8,000 a year, and tens of thousands over a five-year term. That difference is the entire reason to access the broker channel rather than signing the first rate a branch quotes. Adjust the sliders above to your own price and down payment to see your version of the same gap.
What actually sets the rate you qualify for
The posted-versus-broker gap is only the start. The rate National Bank of Canada (or any lender) actually offers you depends on your credit score, your down payment / loan-to-value, whether the mortgage is insured, and the property type — an insured under-20%-down file with strong credit usually prices sharpest. That’s why we put your file in front of National Bank of Canada’s broker desk and 50+ other lenders on one application: you getNational Bank of Canada’s best and the market’s best, then choose.
