Break-Even Switch Calculator (Canada)

The Break-Even Math Explained

The break-even calculation is simple in concept: total switching costs ÷ monthly savings = months to recover. If you have more months remaining on your term than the break-even figure, switching pays. If you have fewer, you'd be better off waiting.

Example: You have $450,000 at 5.49% with 24 months remaining. A new lender offers 4.19%. Monthly saving ≈ $340. Total switching costs = $6,000 penalty + $0 legal (lender covers) + $325 discharge = $6,325. Break-even = $6,325 ÷ $340 = 18.6 months. You have 24 months remaining, so you recover the cost and net ~$1,800 in savings. Switch wins.

Key variables that flip the answer: (1) Size of the penalty — Big 6 IRD penalties can be 5–10× larger than monoline 3-month penalties. (2) Remaining months — 12 months remaining almost never breaks even; 36+ months usually does. (3) Rate gap — a 0.3% drop rarely beats switching costs; 1.0%+ usually does.

The Four Cost Components of Switching

1. Prepayment Penalty (largest)

The greater of 3-month interest or IRD, depending on your lender. Use our Mortgage Penalty Calculator to estimate. Monolines: typically $3,000–$8,000 on a $500k balance. Big 6 with IRD: typically $15,000–$35,000+.

2. Legal Fee ($500–$1,500)

A real estate lawyer or title service is needed to register the new mortgage and discharge the old one. Most new lenders offer "legal paid" promotions — budget $0 if they do, otherwise $800–$1,200 depending on province.

3. Discharge Fee ($200–$400)

Charged by your current lender to remove their charge from title. Provincial fees vary: Ontario ~$325, Alberta ~$250, BC ~$300. Always charged; rarely covered by the new lender.

4. Appraisal Fee ($0–$550)

New lenders may require a property appraisal ($350–$550). Increasingly, many lenders accept AVM (automated valuation models) for low-LTV straight switches — in which case it's $0. Check with the broker before budgeting for this.

When to Switch Mid-Term

• You're on a monoline with a fair 3-month penalty — penalties are small, break-even is fast
• Rate gap exceeds 1.25% — savings outpace almost any cost structure
• 24+ months remaining on your term — enough runway to recover costs
• A new lender is offering cash-back or lender-paid-legal — effectively reduces your switch cost
• You're refinancing anyway for cash-out — the penalty is a sunk cost of doing the refi either way

When to Wait for Renewal

• Big 6 IRD penalty — often $15,000–$40,000 on large balances; usually not beatable
• Less than 12 months left — the 120-day rate hold means you can lock in now and close at renewal penalty-free
• Rate gap under 0.75% — switching costs usually exceed savings
• You're planning to sell or move within 2 years — savings horizon is too short
• You can get equivalent rates by negotiating with your current lender — always call them before switching; many will match or beat to retain

Caveats and Hidden Costs

This calculator uses the remaining-term horizon for savings — not the full amortization. If you switch and the new term ends higher than today's rate, your future renewal may be at a higher rate than if you'd just stayed. Also watch for cash-back clawbacks from your current lender (if you received a sign-on bonus, breaking early may trigger a repayment obligation) and collateral charge re-registration costs at some Big 6 banks where the mortgage is secured via a collateral rather than standard charge.
