For educational purposes only. Calculations are estimates based on your inputs and standard Canadian semi-annual compounding rules. Actual mortgage rates, terms, and payments will vary based on lender requirements and individual qualifications. CMHC insurance premiums and minimum down payment rules are subject to change — verify current requirements with a licensed mortgage professional. This calculator does not constitute financial or mortgage advice.
A mortgage in Canada works differently from mortgages in most other countries. By law, Canadian mortgages are compounded semi-annually rather than monthly — this calculator applies the correct formula so your payment estimates are accurate.
Your down payment determines whether CMHC mortgage insurance is required. Below 20%, you pay a premium (added to your mortgage balance) ranging from 2.80% to 4.00% of the insured amount. At 20% or more, there is no insurance required, which reduces your total mortgage significantly on higher-priced properties.
The amortization period — typically 25 years — determines the length of time to pay off the mortgage and directly affects your payment amount. As of August 2024, first-time buyers and new build purchasers can access 30-year insured amortizations, improving monthly affordability.
Payment frequency matters more than most buyers expect. Accelerated bi-weekly payments (26 per year) are equivalent to one extra monthly payment annually, shaving years off your amortization and saving tens of thousands in interest over the life of the loan.
| Purchase Price | Min. Down |
|---|---|
| Up to $500,000 | 5% |
| $500,001 – $999,999 | 5% + 10% on amount over $500K |
| $1,000,000 – $1,499,999 | ~7.5–10% |
| $1,500,000+ | 20% (no CMHC) |
| Down Payment | Premium |
|---|---|
| 5% – 9.99% | 4.00% |
| 10% – 14.99% | 3.10% |
| 15% – 19.99% | 2.80% |
| 20%+ | $0 |
The minimum down payment in BC depends on the purchase price: 5% on the first $500,000; 5% + 10% on the portion between $500,001 and $1,499,999; and 20% for properties $1,500,000 and above. A down payment of 20% or more eliminates CMHC mortgage insurance, which meaningfully reduces your total mortgage balance on higher-priced homes. Use Scenario 1 in the calculator above — it automatically sets the minimum required down payment based on your purchase price.
CMHC mortgage default insurance protects the lender if you default — it is required any time your down payment is less than 20% and the purchase price is under $1,500,000. The premium is added to your mortgage balance, not paid upfront. Rates: 4.00% (5–9.99% down), 3.10% (10–14.99%), 2.80% (15–19.99%). On an $800,000 home with 5% down, the CMHC premium would be approximately $30,400 — added to your mortgage and amortized over the full period.
Canadian mortgages are compounded semi-annually by law, which is different from the US where mortgages compound monthly. The effective periodic payment rate is calculated as: (1 + annual rate / 2)^(2 / payments per year) – 1. In practice, this means your effective rate is slightly lower than the stated annual rate. This calculator uses the correct Canadian formula — so if your lender quotes you 4.5%, the actual effective monthly rate is approximately 0.3715% rather than 0.375%.
For insured mortgages (less than 20% down), the standard maximum is 25 years. As of August 1, 2024, first-time buyers and new build purchasers can access 30-year insured amortizations — check the "First-time buyer or new build" box in the calculator to unlock this option. For uninsured mortgages (20%+ down), many lenders offer up to 30 years. A longer amortization reduces your payment but significantly increases the total interest paid over the life of the loan — use the side-by-side comparison above to see the difference.
CMHC's gross debt service (GDS) guideline requires that your monthly housing costs — mortgage payment, property taxes, and heating — not exceed 32% of gross monthly household income. The affordability estimate at the bottom of the calculator applies the 32% rule to the mortgage payment in Scenario 1 only. Your actual qualifying income will need to be higher once taxes and heating are included. For Tri-Cities homes in the $800K–$1.2M range, buyers typically need $180,000–$260,000 in gross household income to qualify. Contact Cole Jones at Inlet Mortgage for a precise pre-approval.
Monthly payments are made 12 times per year. Bi-weekly payments are made every two weeks — 26 times per year — which is equivalent to making 13 monthly payments annually. The extra payment goes directly against principal, accelerating your payoff. On a $700,000 mortgage at 4.5% over 25 years, switching from monthly to bi-weekly payments can reduce the amortization by approximately 2.5 years and save over $30,000 in total interest. The calculator lets you select payment frequency per scenario so you can compare directly.
Yes — as of August 1, 2024, first-time homebuyers and buyers of newly built homes can access insured mortgages with a 30-year amortization, provided the purchase price is under $1,500,000. This was introduced to improve housing affordability. The 30-year option reduces monthly payments but increases total interest paid over the life of the mortgage. Use the "First-time buyer or new build" checkbox in the calculator to see both 25-year and 30-year scenarios side by side.
The calculator defaults to 4.50% as a general reference rate — not a current market rate. For accurate estimates, enter the rate being quoted by your lender or mortgage broker for your specific product and term. Rates in BC vary by term length (1, 2, 3, or 5 years), fixed vs. variable, insured vs. uninsured status, and your credit profile.
