★ TOOL · MORTGAGE PREPAYMENT PENALTY · 2026

Breaking your mortgage? Know the bill first.

Most Canadians pay $7,000-$25,000 to break a fixed mortgage. We calculate BOTH penalty types (3-month interest vs IRD) and show which one your lender will charge. The difference can be $20K.

★ YOUR PENALTY

$5,670

Penalty: 3 months interest

3-MONTH INTEREST$5,670
IRD (FIXED ONLY)$3,675
Rule: Fixed-rate lenders charge the GREATER of the two. Variable-rate is always 3-month interest.
★ HOW LENDERS CALCULATE THIS ★

The two formulas

3-MONTH INTEREST(Balance × Rate / 12) × 3

Standard penalty for variable mortgages. Simple, predictable. Typically ranges $5K-$10K.

IRD (Interest Rate Differential)(Contract Rate − Current Rate) × Balance × (Months Left ÷ 12)

Big-Six lenders use POSTED rates (not discounted) which inflates IRD penalties dramatically. Can hit $20K+ on a large mortgage.
