Most people shop mortgages by rate.
That’s understandable — but it’s incomplete.

My Canadian ‘Cost of Borrowing’ APR Mortgage Calculator goes beyond the headline rate and focuses on what actually matters: what the mortgage truly costs you once fees, structure, and timing are accounted for. That’s exactly what APR (Annual Percentage Rate) is designed to capture.

APR isn’t just the interest rate. It’s the all-in annual cost of borrowing, expressed as a single number, once required fees, charges, and compounding effects are included. Two mortgages can advertise the same rate — and still cost very different amounts once APR is considered.

My calculator helps you see that difference clearly.

Think of it this way:

• The interest rate tells you how interest is calculated.

• APR tells you what the mortgage actually costs.

I coded this calculator to make that cost visible — so you can compare mortgages properly, ask better questions, and avoid surprises later.
