Estimates only, not a quote. The regular mortgage uses Canadian semi-annual compounding per the Bank Act and is paid on its schedule; other debts are paid separately at their own rates, and the money left over each month stays in your account. On the offset side, the same money (mortgage payment, debt payments and what's left over) lands every month against one balance in an all-in-one account, charged interest monthly at the rate entered, plus the monthly account fee. It assumes you switch at renewal with no penalty and that rates never change; all-in-one rates are variable. You could also prepay a regular mortgage within its yearly limits or consolidate debts with a regular refinance; this compares against doing neither. The revolving part of these accounts is limited to 65% of your home's value (80% combined) at federally regulated lenders and needs at least 20% equity. Consult a licensed mortgage professional.
