The total loan amount — purchase price minus down payment, plus any mortgage default insurance premium if applicable. This mode calculates payment mathematics only: with a loan amount entered directly, Sidehub cannot determine your purchase price, down-payment percentage, whether insurance was required, or 30-year insured-program eligibility. Switch to "Purchase price + down payment" mode for those checks.
Your contract rate. This calculator assumes a nominal annual rate compounded semi-annually, a common convention for Canadian fixed-rate mortgages.
Total time to pay off the loan. Insured mortgages (<20% down) are limited to 25 years unless eligible for the 30-year insured program.
How long your rate is locked in. The balance owed at term end is shown below for renewal planning.
Accelerated options make an extra month's worth of payments per year, reducing interest significantly.
Applied once per year on top of your regular payments. Shows interest saved and reduced amortization. Lump-sum prepayment privileges vary by lender (often in the 10–20% of original principal range) — this calculator does not validate your entered amount against any specific lender's limit.
- Nominal annual rate compounded semi-annually (period rate = (1 + r/2)^(2/n) − 1), a common convention for Canadian fixed-rate mortgages
- All five standard payment frequencies
- Accelerated payments (monthly/2 bi-weekly, monthly/4 weekly)
- Mortgage default insurance tiers in purchase-price mode, using CMHC's common homeowner premium schedule (2026 rates), including the 30-year insured schedule when eligible
- Minimum down payment and $1.5M insured price cap validation — purchase price + down payment combinations that are not legally financeable are flagged rather than silently treated as uninsured
- Annual lump-sum prepayment simulation
- Balance at end of selected term for renewal planning
- Does not include property tax, heating, or condo fees
- Lump-sum prepayment privileges vary by lender (typically 10–20% of original principal)
- Rate changes at renewal are not modelled
- Does not model reduced insurer/lender eligibility beyond the standard homeowner schedule
- This is an estimate, not a commitment to lend
