What is CMHC Insurance?
In Canada, if your down payment is less than 20% of the home's purchase price, you are legally required to purchase Mortgage Default Insurance. This insurance protects the lender (not you) in case you stop making payments.
While CMHC (Canada Mortgage and Housing Corporation) is the most well-known provider, private insurers like Sagen (formerly Genworth) and Canada Guaranty offer identical products with the same rates.
Premium Rates (Standard)
The premium is calculated as a percentage of your total mortgage amount and is typically added to your mortgage balance:
5% to 9.99% Down: 4.00% Premium
10% to 14.99% Down: 3.10% Premium
15% to 19.99% Down: 2.80% Premium
The $1.5 Million Cap
Homes priced above $1.5 million are not eligible for mortgage default insurance, so they require a down payment of at least 20%. The insured cap was raised from $1 million to $1.5 million on December 15, 2024, and 30-year insured amortizations were expanded at the same time to all first-time buyers and to buyers of newly built homes. For the full premium math, the tiered minimum down payment, and a test for when waiting for 20% down wins, read the companion CMHC mortgage insurance guide for Canada.
Assumptions on this calculator: standard CMHC homeowner schedule by loan-to-value band (4.00% above 90% LTV, 3.10% above 85%, 2.80% above 80%), 25-year amortization pricing, premium added to the mortgage. Provincial sales tax on the premium in Ontario, Quebec, and Saskatchewan is cash at closing and is not included in the total shown. Your lender confirms the final premium and schedule on your application.
CMHC Premium Formula
The premium is calculated strictly on the total amount borrowed (the mortgage amount), not on the purchase price of the home.
Purchase\;Price - Down\;PaymentThe base loan amount you are requesting from the lender
Premium\;RateThe percentage applied based on your down payment tier (2.8% to 4.0%)
Manual Step: Calculating a 5% Down Premium
You are purchasing a home for $500,000. You put down the minimum required 5% ($25,000).
1
1. Calculate Mortgage Base
Subtract your down payment from the purchase price.
2
2. Determine Rate Tier
Because your down payment is exactly 5%, you fall into the highest premium tier.
3
3. Apply Premium Rate
Multiply the base mortgage by 4%.
4
4. Final Mortgage Amount
The $19,000 premium is added to your loan, bringing your total debt to $494,000.
5
Result
You pay interest on this extra $19,000 for the entire life of your mortgage.
Frequently Asked Questions
Do I have to pay CMHC insurance upfront?
No. In almost all cases, the insurance premium is added to your total mortgage balance and you pay it off gradually over the life of your amortization (e.g., 25 years). However, the provincial sales tax (PST) on the premium must be paid upfront in cash on closing day in some provinces like Ontario, Quebec, and Saskatchewan.
Does the premium protect me if I lose my job?
Absolutely not. Mortgage default insurance strictly protects the lender. If you default on your mortgage, the insurer pays the bank. The insurer then has the legal right to pursue you for the shortfall.
Can I avoid CMHC insurance?
Yes, by providing a down payment of 20% or more. This is considered a 'conventional' mortgage and does not legally require default insurance.

The Time Value of Money
The fundamental principle of all finance is the time value of money. A dollar today is worth more than a dollar tomorrow because of its potential earning capacity. This core concept is the engine behind compound interest, mortgages, and retirement planning. When you use financial tools, you are essentially projecting this principle across different time horizons and interest rates to visualize your future wealth.
Navigating Compound Interest
Compound interest is often referred to as the eighth wonder of the world. It is the process where the interest you earn also earns interest. Over long periods, this exponential growth can turn modest savings into substantial wealth. However, it works both ways. Compound interest on debt can quickly overwhelm a budget. This tool helps you quantify that compounding effect so you can make informed decisions about where to deploy your capital.
Risk and Return in Financial Modeling
Every financial calculation inherently involves assumptions about the future. What will the inflation rate be? What is the expected return on the market? These variables introduce risk. A robust financial model doesn't just give you one static number; it allows you to test different scenarios. By adjusting the inputs here, you can stress-test your financial plan against worst-case scenarios.
The Psychology of Financial Planning
Here is what I found: the biggest hurdle in personal finance isn't the math; it's the psychology. Seeing the hard numbers laid out in front of you can be intimidating, but it is also empowering. It removes the ambiguity of 'hoping' you have enough money and replaces it with a concrete target. This tool is designed to give you that clarity, helping you transition from passive saving to active wealth management.
