Payment Summary Help
Monthly Payment
The standard monthly mortgage payment amount. When an accelerated payment scheme (Bi-Weekly or Weekly) is active, this card is labelled "(ref.)" — it shows the baseline monthly reference used for comparisons. Your actual per-payment amount is shown in the Payment Category section under Optional Features.
Payment Frequency
Appears when an accelerated payment scheme is active, showing how often payments are made per year. Accelerated Bi-Weekly (26 payments) and Accelerated Weekly (52 payments) each result in roughly one extra monthly payment per year, reducing total interest and shortening your loan term.
Refinanced Monthly Payment
If you use the refinancing feature, this shows your new monthly payment amount after refinancing.
Total Principal
The total amount borrowed, not including interest.
Total Interest
The total interest paid over the life of your mortgage.
Total Lump Sum Prepayments
The sum of all lump sum prepayments you've added to your calculation.
Total Extra Monthly Payments
The sum of all extra monthly payments over the life of your mortgage.
Total Interest Saved
The amount of interest you'll save compared to a plain monthly mortgage with no optional features. Savings can come from lump-sum prepayments, extra monthly payments, and/or an accelerated payment scheme (Bi-Weekly or Weekly).
Loan Term
The actual time it will take to pay off your mortgage, which may be shorter than your original term if you make prepayments.
Debt Principal Per $100 of Monthly Payment
This is how much extra debt you can take on for every $100 of payment that you are willing to pay, assuming you contribute the same percentage downpayment along with the sum. This, for example, can be used to understand the difference between buying something that has condo fees versus how much more debt you could take on for a house with no condo fees for the same monthly cash outflow.
Optional Features Help
Lump Sum Prepayments
Add one-time payments toward your mortgage principal in specific years.
Payment Category
Choose how frequently you make mortgage payments. Accelerated Bi-Weekly (26 payments/year at half your monthly amount) and Accelerated Weekly (52 payments/year at a quarter of your monthly amount) each result in roughly one extra monthly payment per year. This reduces your total interest paid and shortens your loan term — Weekly pays off slightly faster than Bi-Weekly. Your Monthly Payment card always shows the standard monthly reference; the per-payment amount is displayed below the options when an accelerated scheme is active.
