Calculate Your CMHC Mortgage Insurance Premium

Find out exactly how much mortgage default insurance will cost for your Canadian home purchase.

Calculate CMHC Premium

Key Takeaways

  • Required for down payments under 20%: CMHC insurance is mandatory for high-ratio mortgages
  • Premium rates range from 0.60% to 4.00%: Based on your loan-to-value (LTV) ratio
  • Added to your mortgage: You don't pay upfront—it's added to your principal
  • PST applies in some provinces: Ontario and Quebec charge provincial sales tax on the premium
  • Protects the lender, not you: This is lender insurance, not homeowner protection

In Canada, if you're buying a home with less than 20% down payment, you are required to purchase mortgage default insurance, commonly known as CMHC insurance. This protects lenders if you default on your mortgage. Our CMHC calculator helps you understand exactly how much this insurance will cost and how it affects your monthly payments and total borrowing costs.

What Is CMHC Mortgage Insurance?

Canada Mortgage and Housing Corporation (CMHC) mortgage insurance, also called mortgage default insurance, is a mandatory requirement for Canadian homebuyers who make a down payment of less than 20% of the purchase price. This insurance protects mortgage lenders against losses if a borrower defaults on their loan.

Why Is CMHC Insurance Required?

The Canadian government requires mortgage insurance for high-ratio mortgages (those with less than 20% down) to:

  • Protect the Canadian housing market and financial system
  • Enable more Canadians to buy homes with smaller down payments
  • Reduce risk to lenders, allowing them to offer competitive rates
  • Ensure stability in the mortgage lending industry

Three Mortgage Insurance Providers in Canada

  • CMHC (Canada Mortgage and Housing Corporation): Federal Crown corporation, most common provider
  • Sagen (formerly Genworth Canada): Private insurer, identical rates to CMHC
  • Canada Guaranty: Private insurer, also offers identical rates

Your lender will choose which insurer to use, but the cost to you is identical regardless of provider.

CMHC Premium Rates for 2025

CMHC premium rates are determined by your loan-to-value (LTV) ratio—the amount you borrow compared to the home's value. The smaller your down payment, the higher the insurance premium.

20% or more80% or less0.00%No insurance required
CMHC Premium = Mortgage Amount x Premium Rate

Example: $475,000 mortgage x 4.00% = $19,000 premium

How to Calculate Your CMHC Premium

Step 1: Determine Your Down Payment Percentage

Calculate what percentage of the purchase price you're putting down:

Down Payment % = (Down Payment Amount / Purchase Price) x 100

Step 2: Calculate Your Mortgage Amount

Mortgage Amount = Purchase Price - Down Payment

Step 3: Apply the Premium Rate

Use the rate from the table above based on your down payment percentage:

CMHC Premium = Mortgage Amount x Applicable Premium Rate

Step 4: Calculate Total Mortgage with Premium

Total Mortgage = Mortgage Amount + CMHC Premium

Real Cost Examples

Example 1: First-Time Buyer in Toronto

Scenario: $700,000 condo with 5% down ($35,000)

  • Mortgage Amount: $665,000
  • CMHC Premium (4.00%): $26,600
  • Ontario PST (8%): $2,128
  • Total CMHC Cost: $28,728
  • Total Mortgage: $691,600 (principal + CMHC)
  • Monthly Payment Increase: ~$132/month over 25 years at 5%

Example 2: Moving Up with 15% Down

Scenario: $600,000 home with 15% down ($90,000)

  • Mortgage Amount: $510,000
  • CMHC Premium (2.80%): $14,280
  • Total Mortgage: $524,280
  • Monthly Payment Increase: ~$71/month over 25 years at 5%
  • Savings vs 5% Down: $12,320 less in CMHC premiums

Strategies to Minimize CMHC Costs

1. Save a Larger Down Payment

Increasing your down payment from 5% to 10% reduces your premium from 4.00% to 3.10%. On a $500,000 home, that's a savings of $4,275.

2. Increase to 20% to Avoid CMHC Entirely

Avoiding CMHC insurance altogether requires a 20% down payment but saves you thousands. Consider:

  • Waiting longer to save more
  • Buying a less expensive home
  • Using RRSP Home Buyers' Plan (up to $35,000 withdrawal)
  • Gifted down payments from family (with proper documentation)

3. Consider the RRSP Home Buyers' Plan

First-time buyers can withdraw up to $35,000 from their RRSP ($70,000 for couples) to increase their down payment. This must be repaid over 15 years.

4. Shop for Lower-Priced Homes

Every $10,000 reduction in purchase price saves you approximately $400 in CMHC premiums at the 4% rate.

CMHC Premium Refunds

In some cases, you may be eligible for a CMHC premium refund:

Portability Refund

If you sell your home and port (transfer) your mortgage to a new property, you may receive a partial refund of your CMHC premium when you get new mortgage insurance.

Energy-Efficient Homes

CMHC offers a 25% premium refund for homes that meet specific energy efficiency standards. Requirements include:

  • EnerGuide rating of 82 or higher, OR
  • ENERGY STAR certification, OR
  • Built to specific green building standards

Self-Employed Borrowers and CMHC

Self-employed individuals can qualify for CMHC insurance, but documentation requirements are stricter. You'll typically need:

  • 2+ years of tax returns showing consistent income
  • Notice of Assessment from CRA
  • Business registration documents
  • Lenders may use a lower percentage of your stated income to account for business variability

Frequently Asked Questions

The "Tax Trap": Hidden Cash Requirement

Many buyers forget that in Ontario (8% PST), Quebec (9% QST), and Saskatchewan (6% PST), you must pay sales tax on the CMHC premium.

Crucial Rule: This tax cannot be added to your mortgage. You must pay it in cash at closing.

Example: A $20,000 premium in Ontario requires an extra $1,600 cheque on closing day.

Money Saving Secret: Mortgage Portability

If you move to a new home, you don't have to pay the full CMHC premium again!

You can "port" your existing insurance to the new property. You only pay a "top-up" premium on the new money you borrow. Always ask your lender about portability before breaking your mortgage.
