Your Refinance Breakeven Just Doubled: Why the Math Changed in 2026
Kevin refinanced in 2023 at 1.99%, fixed for five years. He paid $4,200 in legal fees, appraisal, and title insurance to access $85,000 in equity for a kitchen renovation. His breakeven: 22 months. He crossed that line in early 2025. By September 2026, the Bank of Canada policy rate sits at 2.25%, unchanged from a year earlier after reaching that level in October 2025, and Kevin's neighbour is asking whether the same move makes sense now. It doesn't, not on the same timeline.
The Policy Rate Move Changes the Denominator
The policy rate has held at 2.25% since October 2025, but mortgage rates have not followed the same path. Lenders price new fixed-rate mortgages off bond yields, and while variable-rate products track closer to policy, fixed rates remain materially higher than they were 18 months ago. A borrower refinancing in September 2026 sees rates that have changed considerably from early 2025 levels, depending on term and LTV. The refinance costs, legal, appraisal, title insurance, discharge fees, haven't changed. Still $3,500 to $5,500 for most residential deals. What changed is how long it takes for the rate savings to cover those costs.
A refinance that drops your rate by 100 basis points on a $400,000 balance saves roughly $4,000 a year. Breakeven on $4,500 in costs: 13 to 14 months. But in September 2026, fewer borrowers can access a 100-basis-point drop because lender competition has tightened and fixed rates remain elevated despite the policy rate holding at 2.25%. More common now: a 60-basis-point improvement, saving $2,400 a year. Breakeven: 23 months. Nearly double.
Equity Is Expensive to Mobilize When Exit Costs Are Unknown
Kevin's 2023 refinance locked in 1.99% for five years. If rates fall to 3% by 2027, he rides that out with no penalty. But someone refinancing today at 4.39% for five years (insured) or 4.94% (uninsured conventional) faces a different bet. If the Bank of Canada cuts policy back to 2.75% by late 2027, a scenario priced into forward curves as of mid-2026, that borrower who locked an insured rate at 4.39% is locked in 164 basis points above where the market lands. Breaking the mortgage early to refinance again costs three months' interest minimum, often more under the interest rate differential method. On a $500,000 balance at 4.39%, three months' interest is $5,488. Add new closing costs and the second refinance breakeven stretches past three years.
This matters for anyone pulling equity to deploy elsewhere. If you're refinancing to access $100,000 for an investment, you're not just paying 4.39% (insured) or 4.94% (uninsured conventional) on the borrowed amount. You're also paying the present-value cost of being locked in at that rate if the market moves against you.
Three Cases Where the Math Still Works
Refinancing at today's mortgage rates makes sense in three narrow situations. First: debt consolidation where the blended rate you're replacing is above 8%. Credit card debt at 19.99%, a car loan at 7.5%, and a second mortgage at 9% all justify a refinance even at current rates. The breakeven is immediate because the rate differential is wide.
Second: capital deployment into something returning more than the borrowing cost. A business expansion, a rental property acquired below replacement cost, or a Smith Manoeuvre™ setup where the interest is tax-deductible and the invested capital is expected to compound above 5% after tax over a decade. You are funding operations, real estate, or a tax-sheltered investment strategy that generates returns higher than your cost to borrow.
Third: term and product mismatch. A borrower with 18 months left on a 6.2% fixed rate who can lock 4.39% (insured) or 4.94% (uninsured conventional) for five years today pays a penalty to exit early, but the penalty is smaller than the cumulative cost of riding out the old rate. Run the math with actual penalty quotes. Don't assume.
The Holding Period Is the Variable Nobody Stress-Tests
Ask your broker for the breakeven month in writing, with the calculation shown. Then compare it to how long you plan to hold the property and the mortgage. If you're selling in 24 months and your breakeven is 27 months, you lose money on the refinance. If rates drop and you want to refinance again in 30 months, your first refinance hasn't paid for itself before you trigger new costs.
The decision isn't "are rates lower than my current rate." It's "do the savings justify the cost over my actual time horizon, and what happens if the market moves before I hit breakeven." When the policy rate sat below 2.5% in early 2025, most borrowers could ignore the second question. In September 2026, with the policy rate at 2.25% but fixed mortgage rates remaining elevated, it's the first thing to model.
