Mortgage Penalty Calculator — Vancouver BC
Selling, switching lenders, or refinancing? Estimate your IRD or 3-month-interest penalty before you pay tens of thousands you didn't expect.
This mortgage penalty calculator for Vancouver BC estimates the prepayment charge you'll pay if you break a fixed-rate mortgage early. Canadian lenders charge the greater of:
- 3 months of interest on your balance, or
- Interest Rate Differential (IRD) — the lender's lost-revenue calculation.
For variable-rate mortgages it's typically just 3 months interest. Big-6 banks tend to use POSTED rates which inflates IRD significantly versus credit unions.
How Mortgage Penalties Work in Vancouver BC
3 Months Interest Method
Formula: Balance × (Contract Rate ÷ 12) × 3. This is straightforward and is the standard penalty for variable-rate mortgages and most short remaining terms.
Interest Rate Differential (IRD)
Formula: Balance × (Contract Rate − Current Comparison Rate) × Months Remaining ÷ 12.
"Current Comparison Rate" is your lender's current rate for the term closest to your remaining term. Big-6 banks use their posted rate (typically 1.5%–2% above their discounted rate) which dramatically inflates IRD penalties.
When IRD Hurts the Most
- Rates have fallen meaningfully since you locked in.
- You have 2+ years remaining in your term.
- You're with a Big-6 bank using posted-rate IRD.
FAQ
How much is a typical Vancouver mortgage penalty?
For a $600K balance with 2 years left at a 4.79% rate, expect $3,000–$8,000 if rates are roughly stable, but $15,000–$30,000+ if rates have fallen and you're with a big bank using posted-rate IRD.
Can I avoid the penalty by porting my mortgage?
Often yes — if you're buying another property, you can port your existing mortgage to it and avoid the penalty entirely. Ask your lender about the porting window (usually 30–120 days).
