CMHC Insurance Calculator
Calculate your CMHC mortgage default insurance premium and minimum down payment.
How it works
Premium = loan × rate. CMHC rates by loan-to-value: 80.01–85% 2.80%; 85.01–90% 3.10%; 90.01–95% 4.00% (traditional down payment). Amortization over 25 years adds 0.20%. Minimum down: 5% of the first $500,000 + 10% of the portion up to $1.5M; homes $1.5M+ need 20%. Provincial sales tax on the premium (ON, QC, SK) is not included.
Examples
- $500,000 home, 5% down: $475,000 × 4.00% = $19,000.
- $500,000 home, 10% down: $450,000 × 3.10% = $13,950.
