CMHC premium calculator.
Any Canadian mortgage with less than 20% down needs CMHC mortgage default insurance. This runs the complete published premium table — homeowner and small rental, standard and extended amortization — not just the standard high-ratio band.
The premium is a percentage of your mortgage amount, banded by loan-to-value (LTV): from 0.60% at 65% LTV or less up to 4.00% at 90.01–95% LTV for an owner-occupied home. A 30-year amortization (insured mortgages only, for first-time buyers or new construction) adds a 0.20% surcharge. In Ontario, provincial sales tax of 8% applies on top of the premium — paid in cash at closing, since CMHC does not allow the tax itself to be added to the loan.

The complete premium table
CMHC (Canada Mortgage and Housing Corporation) insures any residential mortgage with less than 20% down. The premium is charged as a percentage of the mortgage amount (not the purchase price), and the rate depends on your loan-to-value ratio — how much you're borrowing relative to the home's value.
| Loan-to-value | Owner-occupied (1–4 units) | Small rental (2–4 units) |
|---|---|---|
| Up to 65% | 0.60% | 1.45% |
| 65.01%–75% | 1.70% | 2.00% |
| 75.01%–80% | 2.40% | 2.90% |
| 80.01%–85% | 2.80% | not insurable (rental max 80% LTV) |
| 85.01%–90% | 3.10% | — |
| 90.01%–95% | 4.00% (4.50% if down payment is non-traditional) | — |
The 30-year amortization surcharge
CMHC introduced a 30-year amortization option on 1 August 2024, but only for insured mortgages taken out by first-time buyers or purchasers of new construction. Any amortization beyond 25 years — this 30-year option, or a refinance on a longer schedule — carries an additional 0.20% surcharge on the premium rate, on top of whichever LTV band applies.
The $1,500,000 insurable price cap
A mortgage cannot be CMHC insured at all if the purchase price is $1,500,000 or more. That cap was raised from $1,000,000 effective 15 December 2024. At or above the cap, 20% down is mandatory and no premium calculation applies.
Provincial sales tax on the premium
Ontario, Quebec and Saskatchewan charge provincial sales tax on the CMHC premium itself. CMHC does not allow that tax to be added to the mortgage — it is due in cash at closing, separately from your down payment. In Ontario the rate is 8%, which this calculator applies directly. Quebec and Saskatchewan also charge PST on the premium, but this tool doesn't compute a dollar figure for those two provinces because their exact current rate wasn't independently re-confirmed for this build — confirm the figure with your lender or notary before closing.

Frequently asked questions
Is the CMHC premium added to my mortgage or paid up front?
It is normally added to (financed within) the mortgage, so you pay it off gradually with interest rather than in cash at closing. The one exception is provincial sales tax charged on the premium in Ontario, Quebec and Saskatchewan — CMHC requires that tax to be paid in cash, separately, because it cannot be added to the loan.
What's the difference between loan-to-value and down payment percentage?
They're complements: down payment % + loan-to-value % = 100%. A 5% down payment means a 95% loan-to-value ratio, which is why the same transaction is sometimes described by its down payment and sometimes by its LTV in different lender paperwork.
Can I get a 30-year amortization on any insured mortgage?
No. CMHC's 30-year insured amortization is restricted to first-time home buyers or buyers of a newly constructed home. Every other insured mortgage is capped at 25 years.
Why is the small rental table different from the homeowner table?
CMHC treats a non-owner-occupied small rental property (2–4 units) as higher risk. It requires a minimum 20% down payment (so it's never available at the 5%–19.99% down bands homeowners use), caps insurability at 80% loan-to-value, and charges higher rates at every matching LTV band.
Estimate only — not legal or financial advice
This tool calculates the CMHC mortgage default insurance premium from CMHC's own published rate table. It does not model portability premium credits or increases, self-employed non-traditional-income surcharges beyond the down-payment-source case shown here, or Quebec/Saskatchewan PST dollar amounts (flagged but not computed — see above). Confirm your exact premium and closing costs with your lender or mortgage broker.
