Frequently Asked Questions
How much do extra mortgage payments save?
Extra monthly payments reduce your principal balance faster, lowering total interest and shortening your loan term. Even $200–$500 extra per month can save tens of thousands over a 25-year mortgage. Use the Extra Payment Calculator above to see your exact savings.
How do I calculate my refinance break-even point?
Divide your total closing costs by your monthly payment savings. For example, $8,000 in closing costs with $200/month savings means a 40-month (3.3 year) break-even. If you plan to stay longer, refinancing saves you money.
What is an amortization schedule?
An amortization schedule shows each payment broken down into principal and interest, along with your remaining balance. In the early years, most of each payment goes to interest — the schedule shows exactly when that flips.
How much mortgage can I afford in Canada?
Canadian lenders use the Gross Debt Service (GDS) ratio (max 39%) and Total Debt Service (TDS) ratio (max 44%) to determine affordability. You also need to qualify at the stress test rate (your contract rate + 2%, or 5.25%, whichever is higher). Use the Affordability Calculator above to find your maximum.
