Mortgage Inputs
Enter the current mortgage details and the investment return available for prepayments.
Current Mortgage
Annual rate percentage, compounded semi-annually for Canadian mortgage payment math.
Investment Return
Example: $100,000 at 10.14% generates $10,140 annually.
The calculator allocates the annual return to monthly prepayments first, up to the 20% monthly privilege, then applies the remaining return to the anniversary prepayment privilege. Neither 20% privilege needs to be maxed out.
Prepayment Privileges
Monthly privilege: up to 20% additional monthly payment.
Anniversary privilege: up to 20% lump-sum prepayment on each anniversary date.
