Canadian mortgage calculator with land transfer tax
Correct Canadian math for monthly payments, CMHC insurance, plus city-aware Ontario and Toronto Municipal Land Transfer Tax with first-time buyer rebates.
How the math works
What this calculator actually does
Canadian semi-annual compounding. Closed fixed-rate
mortgages in Canada are compounded semi-annually, not in advance. The
calculator converts the stated annual rate into the correct effective
monthly rate using the formula
(1 + annual/2)(1/6) - 1, then applies the
standard mortgage amortization formula. Variable-rate mortgages use
monthly compounding; this calculator models the fixed-rate case.
CMHC insurance. When the down payment is less than 20% of purchase price, federal regulations require mortgage default insurance. The calculator applies the published CMHC premium schedule: 4.00% (down payment 5% to less than 10%), 3.10% (10% to less than 15%), 2.80% (15% to less than 20%), and 0% (20%+).
Ontario Land Transfer Tax (provincial). Applied on a marginal basis: 0.5% on the first $55,000; 1.0% on $55,001 to $250,000; 1.5% on $250,001 to $400,000; 2.0% on $400,001 to $2,000,000; 2.5% above $2,000,000.
Toronto Municipal Land Transfer Tax. Applied only for purchases in the City of Toronto, including Scarborough. Calculated marginally: 0.5% on the first $55,000; 1.0% on $55,001 to $250,000; 1.5% on $250,001 to $400,000; 2.0% on $400,001 to $2,000,000; 2.5% on $2,000,001 to $3,000,000; 3.5% on $3,000,001 to $4,000,000; 4.5% on $4,000,001 to $5,000,000; 5.5% on $5,000,001 to $10,000,000; 6.5% on $10,000,001 to $20,000,000; 7.5% above $20,000,000 (the City of Toronto's luxury home tax tiers as set out in by-law).
First-time buyer rebates. For first-time buyers, the calculator deducts up to $4,000 from the Ontario LTT and up to $4,475 from the Toronto MLTT (Scarborough purchases only). Rebates cannot exceed the actual tax due.
Good to know
Frequently asked - mortgage & LTT
Why is the math 'semi-annual compounding'?
Canadian closed fixed-rate mortgages are by federal regulation compounded semi-annually, not in advance. That is different from US mortgages which are typically compounded monthly. Our calculator uses the correct Canadian effective monthly rate so the payment matches what an actual lender will quote you.
What is CMHC mortgage insurance?
When your down payment is less than 20% of the purchase price, federal regulations require mortgage default insurance, typically through the Canada Mortgage and Housing Corporation (CMHC), Sagen or Canada Guaranty. The premium is calculated as a percentage of the loan amount and is normally rolled into the mortgage. Our calculator estimates the premium based on standard CMHC tiers.
Why does my Scarborough purchase have higher land transfer tax than my Pickering purchase?
The City of Toronto (which includes Scarborough) charges its own Municipal Land Transfer Tax (MLTT) in addition to the provincial Ontario Land Transfer Tax. Pickering is in Durham Region, not the City of Toronto, so only the provincial tax applies. On a $1M purchase, that difference alone can be roughly $15,000-$16,000 - real money on closing day.
What are the first-time home buyer rebates?
First-time buyers in Ontario can claim up to $4,000 against the provincial Ontario Land Transfer Tax. For Toronto purchases (including Scarborough), first-time buyers can also claim up to $4,475 against the Toronto Municipal LTT. Our calculator applies both rebates automatically when you tick the first-time buyer box.
How accurate is this calculator?
It is accurate for standard residential mortgages with the inputs you provide, using the correct Canadian semi-annual compounding for fixed rates. It is not a substitute for an actual mortgage approval - lenders apply qualifying rules, debt-service ratios and credit assessment that this calculator cannot. Use these numbers to plan; talk to a mortgage broker to lock them in.
