Mortgage Lab
A little perspective. A lot of possibility.

Clarity for your next move.

Model loans, leverage, and reverse mortgages — with rates that change mid-term, like real life.

Rate changes

Available for variable rates only. Saved changes are retained.
Enter increases or decreases in percentage points. Each adjustment applies to the previous rate, in chronological order.
The payment holds at its original amount. If the rate climbs high enough that the payment no longer covers interest, it rises to cover interest only, then falls back once the rate drops. Only matters once a rate change is added.

The investment

%
Entered rate is nominal; effective annual growth depends on the compounding chosen.

Account allocation

Split the borrowed amount across account types. Only the non-registered share has deductible interest; RRSP contributions earn a tax refund; TFSA growth is tax-free. Boxes auto-balance to 100%.

Applies to non-registered money only.

Monthly contribution

Money added from cash flow, not from the loan. It earns the same return but carries no interest and no deduction, and never changes the amount borrowed.

Tax

%
%
The rate you expect when withdrawing from an RRSP. A lower rate than today is what makes an RRSP pull ahead.

Market changes

Vary the borrowing rate and/or market return at points in the horizon.
Enter increases or decreases in percentage points. Each adjustment applies to the previous rate, in chronological order.
