If your down payment is less than 20%, you're required to purchase CMHC mortgage default insurance. This calculator shows you exactly how much it will cost and how it affects your total mortgage.
CMHC insurance protects the lender — not you — but it enables you to buy a home with as little as 5% down.
Enter your purchase price and down payment to calculate your insurance premium.
CMHC premium is added to your mortgage and amortized over your mortgage term. Provincial sales tax (PST) on the premium must be paid upfront at closing — Alberta has no PST on CMHC premiums.
| Down payment | Premium rate |
|---|---|
| 5% – 9.99% | 4.00% of mortgage |
| 10% – 14.99% | 3.10% of mortgage |
| 15% – 19.99% | 2.80% of mortgage |
| 20%+ | No insurance required |
CMHC insurance is required for all purchases with less than 20% down where the purchase price is under $1.5M. The premium is added to your mortgage — you don't pay it upfront.
