Money Figures

Down payment & mortgage insurance calculator

Find the minimum down payment and estimate a standard CMHC premium, including eligible 30-year insured scenarios, for a Canadian owner-occupied home.

Your numbers

For a traditional down-payment source and a one- or two-unit, owner-occupied home.

Why is the financed mortgage larger?

The base loan is the purchase price minus your down payment. For an insured scenario, the estimated premium is added to that base loan. Ontario, Quebec and Saskatchewan premium sales tax cannot be financed and is excluded here.

Choose 30 years only if that is the mortgage you are evaluating. For high-ratio insured loans, 30-year eligibility is limited.

What changes at 30 years?

This insured model permits 30 years only when you confirm first-time buyer or new-build eligibility, and adds a 0.20 percentage-point premium surcharge. Confirm all lender and insurer conditions separately.

For this tool, select Yes only if at least one borrower meets the federal first-time-buyer definition.

Select Yes only if the home has not previously been occupied for residential purposes, apart from permitted interim occupancy for a new condominium.

Why this number?

For prices below C$1.5 million, the minimum is 5% of the first C$500,000 plus 10% of the remainder. At C$1.5 million or more, this tool uses a minimum of 20%. These are price-based minimums, not a guarantee that a lender will approve the loan.

Assumptions & methodology

Minimum down payment

For prices below C$1.5 million, the minimum is 5% of the first C$500,000 plus 10% of the remainder. At C$1.5 million or more, this tool uses a minimum of 20%. These are price-based minimums, not a guarantee that a lender will approve the loan.

Standard premium

For down payments below 20%, this tool uses CMHC Purchase's standard homeowner premium tiers: 2.80% for LTV above 80% through 85%, 3.10% above 85% through 90%, and 4.00% above 90% through 95%. For an eligible insured amortization beyond 25 years, it adds CMHC's 0.20 percentage-point surcharge. The premium is calculated on the base loan and is assumed to be financed. At 20% down or more, no borrower-paid default-insurance premium is assumed.

What this version covers

This estimate covers a traditional down-payment source and a one- or two-unit owner-occupied home. It supports 25-year insured scenarios and eligible 30-year insured scenarios for first-time buyers or buyers of newly constructed homes. It does not determine whether you meet every insurer or lender condition, and it excludes non-traditional down payments, premium rebates, porting, refinancing, lender-required insurance at 20% down or more, sales tax on premiums and other closing costs. Confirm eligibility and cash costs with your lender.

A worked example

For a C$750,000 home, the minimum is C$50,000. With that down payment and a 25-year insured amortization, the base loan is C$700,000, the standard premium estimate is C$28,000 and the financed loan amount is C$728,000. An eligible 30-year insured scenario adds the applicable 0.20 percentage-point surcharge.
