Canadian Mortgage Payment Calculator

Calculate Canadian mortgage payments with CMHC insurance, amortization schedules, and stress test qualification using this mortgage calculator canada.

Canadian mortgages follow distinct legislated rules compared to other countries:

  • Semi-Annual Compounding: By law, interest rates in Canada are compounded semi-annually rather than monthly. This makes the effective interest rate slightly different.
  • CMHC Default Insurance: Purchases with less than 20% down payment require default insurance. Premiums range from 2.80% to 4.00% and are added to the loan.
  • Stress Test: Lenders qualify buyers at either the contract rate + 2%, or 5.25% (whichever is higher), to ensure affordability if rates rise.

Understanding Canadian Mortgages

Canadian mortgages are calculated differently than US mortgages. Under Canadian law, mortgage interest must be semi-annually compounded for fixed-rate mortgages. Buyers with down payments under 20% must also purchase CMHC default insurance.

How Canadian Mortgage Payments are Determined

Canadian fixed mortgages use a semi-annual interest compounding model:

  1. Determine Net Principal: Price - Down Payment + CMHC Insurance Premium (if down payment is under 20%).
  2. Calculate Effective Monthly Rate (i): Compounded semi-annually, so i = (1 + r/2)^(2/12) - 1, where r is annual rate.
  3. Define Number of Payments (n): Amortization in years multiplied by 12 (standard limit is 25 years with under 20% down).
  4. Apply Canadian Payment Formula: Monthly Payment = Principal * [i * (1 + i)^n] / [(1 + i)^n - 1].

Canadian Mortgage Standards & Caps

Parameter / Bracket Rate / Amount
Maximum Amortization (Down < 20%) 25 Years
Maximum Amortization (Down >= 20%) 30 Years
CMHC Insurance Premium Range 0.6% to 4.0% of loan amount
Standard Stress Test Rate Contract rate plus 2.0%, or 5.25% (whichever is higher)

Frequently Asked Questions about Canadian Mortgages

CMHC insurance is default insurance provided by the Canada Mortgage and Housing Corporation. It is legally required for buyers with down payments between 5% and less than 20%.
Under the Canadian Bank Act, fixed-rate mortgages are legally required to be compounded semi-annually. This results in slightly less interest paid compared to US mortgages, which compound monthly.
