Budget sensitivity only; this is not the lender’s stress test.Example: buying at $600,000 with 10% or 20% down
These two illustrative scenarios use the same 4.5% fixed rate, 25-year amortization and monthly payments. This is not a rate offer. They use the calculator’s method and exclude property taxes, home insurance, condo fees and maintenance.
| Down payment | Financed amount | Monthly payment |
|---|---|---|
| $60,000.00 (10 %) | $556,740.00 | $3,081.41 |
| $120,000.00 (20 %) | $480,000.00 | $2,656.67 |
Why does the financed amount differ?
In the 10% scenario, the model adds a $16,740 CMHC premium to the $540,000 loan. The $1,506.60 Quebec tax on that premium is payable separately. In the 20% scenario, the model uses a $480,000 loan with no borrower-paid premium. Compare the cash required as well as the payment; a lower payment alone does not determine the best choice.
How the estimate works
The fixed annual rate uses Canadian semi-annual compounding. Regular biweekly payments equal the monthly payment × 12 ÷ 26; accelerated biweekly payments equal half the monthly amount, paid 26 times per year. The latter therefore represents roughly one additional monthly payment annually. Actual lender payment conventions may differ.
Below 20% down, the estimate adds a standard CMHC premium to the loan: 4%, 3.1% or 2.8%, depending on loan-to-value, plus 0.2 percentage points for insured amortization over 25 years. An insured 30-year mortgage requires first-time buyer or new-build eligibility. At 20% down or more, no borrower-paid default insurance is assumed. Rebates, portability and special products are excluded.
The 9% Quebec tax on the premium is payable separately and is not added to the insured loan. For a price of $1.5 million or more, the model requires at least 20% down. Confirm all terms with your lender; no rate or loan is offered through this tool.
Put your budget in context
Keep room for the notary, inspection, moving costs and a reserve for unexpected expenses. A payment estimate is only one part of deciding which property fits your plans.
