Your current mortgage
Pre-set for CIBC, based on how it describes its prepayment charge. You can change it if your contract says otherwise.
Using a posted rate of 6.05% for the 3.0 years you have left, less a discount of 1.84 points worked out from your start date and rate. Posted rates are the big-bank average published by the Bank of Canada, 2026-09-23; your own bank’s may differ.
Minimum savings threshold
Only flag breaking as worthwhile if savings exceed this. Breaking involves legal fees and paperwork, so small savings may not be worth the effort.
Your break analysis
Technically yes — but below your savings threshold
Savings of $14,031 — below your $15,000 threshold
Breaking now would save about $14,031, which is less than the $15,000 you said would make it worth the effort. After legal fees and paperwork it may not be worth your time.
What to consider
Your payment drops by roughly $398 per payment.
Over the comparison window you pay $14,338 less, but owe $307 more at the end.
Estimated break penalty
IRD $9,291 vs 3-month interest $6,745 — IRD applied
IRD measured against 4.21%: posted rate less your original discount, the bank method
Measured the other way the IRD would be $14,798. Lenders differ, and only a payout statement settles it.

How CIBC measures the penalty
CIBC describes the fixed-rate charge as the greater of three months' interest and the interest rate differential. It words the IRD as the difference between interest over the remaining term at your current rate plus any discount you received, and interest at CIBC's current posted rate for the comparison mortgage named in your documents. That works out the same as posted rate less discount. CIBC also describes the three months' interest on a fixed-rate mortgage as calculated at your rate plus any discount received, and for a variable-rate mortgage at the CIBC Prime Rate, so its three-month figure can differ from the simple balance times rate estimate.
In the calculator this is the "big bank or credit union" setting: the interest rate differential is measured against a posted rate for the time left, less the discount you were given when you signed. The calculator uses the Bank of Canada's average big-bank posted rates, and CIBC's own posted rates may differ, which is one reason your figure may not match.
Every mortgage contract sets its own terms, and older or specialty products can differ from what a lender publishes today. If the scenario looks worth exploring, you may wish to ask CIBC for a payout statement, which is the figure that counts.

- For a fixed-rate closed mortgage, CIBC describes the charge as: the greater of three months' interest and the interest rate differential (IRD), on the amount you prepay. The IRD is measured against CIBC's posted rate, adjusted for the discount you received when you signed. Your mortgage contract governs, and only CIBC can give you the actual figure.
- What is the penalty for breaking a CIBC variable-rate mortgage?
- CIBC describes the charge on a variable-rate closed mortgage as: three months' interest on the amount you prepay, calculated at the CIBC Prime Rate. On a $400,000 balance at 5%, three months' interest is about $5,000.
- How much can I prepay on a CIBC mortgage without a penalty?
- CIBC describes a prepayment of up to 10% of the original mortgage amount each year on its standard fixed-rate closed mortgage (10%, 15% or 20% depending on the product), and payment increases of up to 100% of the regular payment. Amounts above these limits usually carry a prepayment charge. Privileges differ by product, so you may wish to confirm yours in your mortgage documents.
- Does CIBC have its own mortgage penalty calculator?
- Yes. CIBC publishes a prepayment charge calculator on its website. For an existing CIBC mortgage it is a more authoritative estimate than a general calculator like this one, and a payout statement from CIBC is the figure that counts.
- Why might CIBC's figure differ from this estimate?
- This calculator uses the Bank of Canada's average big-bank posted rates and the numbers you enter. CIBC's own rates, the exact term it compares against, how it counts the days remaining, and any fees can all change the result. These figures are estimates based on the information entered.
