Compounding Methodology: Under the Canadian Interest Act, fixed-rate residential mortgages must be compounded semi-annually, not in advance. Our mortgage payment widgets implement standard Canadian actuarial compounding rather than US monthly compounding formulas, ensuring exact penny-matching with Canadian chartered bank schedules.
Stress Test & Debt Service: The debt service ratio widget applies federal OSFI Guideline B-20 rules, calculating Gross Debt Service (GDS limit typically 39%) and Total Debt Service (TDS limit typically 44%) using standard qualifying benchmarks (the higher of contract rate + 2.00% or 5.25%).
Broker & Realtor Use: Licensed real estate brokerages and agents are permitted to embed these tools freely on listing pages and client resources. Modest attribution beneath each embed helps keep the computational engine freely accessible to all Canadian homebuyers.
