Our Canadian mortgage calculator uses industry-standard formulas adapted for Canadian mortgage practices to provide accurate payment estimates. All calculations follow IFRS 9 guidelines and include proper regulatory compliance features.
1. Principal and Interest Calculation
The core of your mortgage payment uses the standard amortization formula with Canadian semi-annual compounding:
Where:
- P = Principal loan amount (property price - down payment + CMHC premium)
- r = Monthly interest rate (converted from semi-annual compounding)
- n = Total number of payments (years × 12)
Semi-Annual Compounding Conversion
Canadian law requires fixed-rate mortgages to compound semi-annually:
Example Calculation
For a $500,000 property with $100,000 down payment, 5.5% interest rate, and 25-year term:
- Base Principal: $400,000
- CMHC Premium: $12,000 (3% for 10% down payment)
- Total Principal: $412,000
- Monthly rate: 0.453% (converted from 5.5% semi-annual)
- Total payments: 25 × 12 = 300
- Monthly payment: $2,456.78
2. Row-by-Row Rounding (Accounting Best Practice)
For maximum accuracy, our calculator uses row-by-row rounding:
- Each period's interest is rounded to 2 decimal places
- Each period's principal is rounded to 2 decimal places
- Each period's balance is rounded to 2 decimal places
- Total interest and principal are derived from summing the rounded schedule rows
3. CMHC Insurance Calculation
CMHC insurance is required when down payment is less than 20%:
CMHC Rates (2024):
- 5% down: 4.0%
- 10% down: 3.1%
- 15% down: 2.8%
The premium is added to the loan amount, not paid separately, as per Canadian convention.
4. Property Tax Calculation
Property taxes are typically paid monthly:
Property tax rates vary by province and municipality, typically ranging from 0.5% to 2.5% of assessed value.
5. Home Insurance
Home insurance is typically paid monthly:
Insurance costs depend on your home's replacement value, location, and coverage level.
6. Land Transfer Tax
Land transfer tax is a one-time tax on property purchases:
- Ontario: 0.5% to 2.5%
- British Columbia: 1% to 3%
- Alberta: 0% (no land transfer tax)
- Other provinces: Varies
7. Legal Fees
Legal fees for property purchase:
Typical range: $1,000 - $2,500, varies by province and complexity
8. Extra Payments
Our calculator handles additional payments to help you pay off your loan faster:
- Extra Monthly Payment: Additional amount paid each month
- One-time Payment: Lump sum payment in the first month
Extra Payment Impact
Extra payments are applied to reduce the principal balance, which:
- Reduces the total interest paid over the loan term
- Shortens the loan duration
- Creates a new amortization schedule
9. Total Monthly Payment
10. Total Cost Calculation
The total cost includes all components:
Where:
- Property Price: Purchase price of the property
- Total Interest: Sum of all interest payments over loan term
- CMHC Insurance: Insurance premium amount
- Land Transfer Tax: Provincial transfer tax
- Legal Fees: Legal representation costs
11. IFRS 9 Compliance Calculations
Our calculator implements International Financial Reporting Standards (IFRS 9) for accurate financial reporting:
Expected Credit Loss (ECL) Allowance
IFRS 9 requires ECL recognition from day one:
- Reduces the carrying amount of the loan
- Based on credit risk assessment
- Affects effective interest rate calculation
- Typical rates range from 0.1% to 2.0%
- Default: 0.5% (typical for residential mortgages)
Effective Interest Rate (EIR)
We calculate the true effective interest rate that considers:
- CMHC insurance premium
- Expected Credit Loss (ECL) allowance
- Incremental transaction costs
- Carrying amount adjustments
12. Amortization Schedule Generation

- Payment Number: Sequential payment identifier

- Rounding: Standard banking rounding rules
Canadian-Specific Considerations
Mortgage Types
- Fixed-Rate Mortgages: Interest rate stays the same for the term
- Variable-Rate Mortgages: Interest rate can change with Bank of Canada rate
- Adjustable-Rate Mortgages: Payment changes with interest rate
- High-Ratio Mortgages: Less than 20% down payment (requires CMHC insurance)
Stress Testing
Canadian lenders must stress test mortgages:
- Qualify at higher interest rates
- Consider debt service ratios
- Maximum loan-to-income ratios
