How this is calculated
- The qualifying rate is the higher of your contract rate + 2% or 5.25%. You still pay your actual rate; the higher rate is only used to test the mortgage.
- GDS counts the mortgage payment, property tax, heat and half of any condo fees. TDS adds all other debt payments. CMHC limits are 39% and 44%; individual lenders may be stricter or more flexible.
- The largest-mortgage figure assumes the same 25-year amortization and the costs you entered. It is an estimate, not a pre-approval.

But how does this apply to your business income?
This calculator estimates the numbers you entered. How a lender treats your salary, dividends or business income is a separate question, and it's the one the Mortgage Readiness Review looks at first.
