    Total Cost of Borrowing

    Quick Definition

    The entire amount paid above the principal over the life of a loan.

    Full Explanation

    Total cost of borrowing refers to all costs paid above and beyond the original principal balance over the entire life of a loan. This includes all interest payments, origination fees, broker fees, insurance premiums (like CMHC), and other charges. For a $400,000 mortgage at 6% amortized over 25 years, the total interest paid is approximately $344,000 — meaning you pay $744,000 for a $400,000 home. Canadian regulations require lenders to disclose the total cost of borrowing under the Cost of Borrowing Regulations (COBR). This figure is the most impactful number for long-term loan decisions.
