How This Calculator Works

Canadian Mortgage Compounding

Canadian mortgages compound semi-annually (not monthly). This calculator converts the semi-annual rate to a monthly equivalent before calculating your payment.

CMHC Mortgage Insurance

Required when your down payment is less than 20%. Rates range from 2.80% to 4.00% of the mortgage amount, added to your mortgage balance.

Ontario Land Transfer Tax

Calculated on a sliding scale up to 2.5% for homes over $2M. First-time buyers receive a rebate of up to $4,000 (Ontario) and up to $4,475 (Toronto).

Closing Costs

Our estimate includes LTT, legal fees (~$1,800), title insurance, home inspection (~$600), and adjustments. Budget 1.5%–4% of the purchase price.
