Calculate Your CMHC Insurance Premium
What Is CMHC Mortgage Insurance?
In Canada, if your down payment is less than 20% of the purchase price, you must purchase mortgage default insurance. This insurance protects the lender (not you) in case you default on your mortgage.
Three companies provide mortgage default insurance in Canada:
- CMHC (Canada Mortgage and Housing Corporation) — A Crown corporation
- Sagen (formerly Genworth Canada)
- Canada Guaranty
All three use the same premium rate structure, so the cost is the same regardless of the insurer.
CMHC Insurance Premium Rates
| Down Payment % | Premium % of Mortgage | Example on $600K Mortgage |
|---|---|---|
| 5.00% – 9.99% | 4.00% | $24,000 |
| 10.00% – 14.99% | 3.10% | $18,600 |
| 15.00% – 19.99% | 2.80% | $16,800 |
| 20.00% or more | 0% (not required) | $0 |

Minimum Down Payment in Canada
| Home Price | Minimum Down Payment |
|---|---|
| Up to $500,000 | 5% of purchase price |
| $500,001 – $999,999 | 5% of first $500K + 10% of remainder |
| $1,000,000+ | 20% minimum (no CMHC insurance available) |
Example: Minimum Down Payment on a $750,000 Home
5% of $500,000 = $25,000
10% of $250,000 = $25,000
Total minimum: $50,000 (6.67% of purchase price)
How to Avoid CMHC Insurance
The only way to avoid CMHC insurance is to make a down payment of 20% or more. While saving a larger down payment takes time, it can save you tens of thousands in insurance premiums.
