Worked example: the same mortgage at CIBC and at National Bank
You owe $480,000 on a $500,000 5-year fixed at 5.29%, signed when the posted 5-year rate was 6.89% (a 1.60-point discount). There are 30 months left and you need to sell without porting. The payment, about $3,064.75 a month, is the same at either bank; what differs is the exit.
| CIBC | National Bank | |
|---|---|---|
| Compares with | 2-yr posted | 2- and 3-yr rates, interpolated for 30 months |
| Comparison rate after discount | 3.64% | 4.07% |
| 3 months’ interest | $8,268 | $8,268 |
| Penalty if you break now | $19,800 | $15,200 |
| Penalty if posted rates fall 1 point first | $31,800 | $27,200 |
| Most lump-sum room stated, on the original amount | $100,000 | $50,000 |
| Penalty after using this year’s lump sum first | $15,675 | $13,669 |
| Porting | All CIBC mortgages except Variable Flex can be ported; the charge may be waived or reimbursed in full or in part, and a delayed port allows up to 120 days. | Rollover Mortgage: balance, rate and term move to a new National Bank mortgage for your next home, and the prepayment charge is recovered; no window stated. |
Where CIBC and National Bank differ most
- Breaking the same mortgage after rates fall a point costs $4,600 more at CIBC ($31,800 vs $27,200): CIBC compares with its 2-yr posted rate and National Bank with its 2- and 3-yr rates, interpolated for 30 months rate.
- Which bank is cheaper to leave depends on when you leave: across the term the lead changes hands. The gap is widest with 30 months left: $19,555 at CIBC (2-yr posted) vs $15,018 at National Bank (2- and 3-yr rates, interpolated for 30 months).
- Prepayment room differs by $50,000 a year on a $500,000 mortgage (CIBC 10%, 15% or 20% by product, National Bank 10% a calendar year).
Both use rate plus discount in part of the formula; CIBC by chart, National Bank by interpolation.
CIBC and National Bank are the two banks whose 3 months’ interest is figured at your rate plus your discount (National Bank calls it the posted rate). Beyond that they differ: CIBC assigns your months left to a term with a published chart, National Bank interpolates between two terms and adds one month’s interest up to $500. CIBC allows payment increases up to 100%; National Bank lets you add up to one regular payment on each payment date.
Ask: Ask both for a written penalty quote on the same payout date; the two methods can disagree by more than you’d expect.
When would breaking cost less at CIBC or at National Bank?
The same $500,000 mortgage, broken at five points in its 5-year term (balance paid down on schedule, today’s posted tables). Each bank’s comparison term changes at different months, so the gap opens and closes:
| Months left | CIBC penalty | National Bank penalty | CIBC compares with | National Bank compares with |
|---|---|---|---|---|
| 54 | $15,595 | $18,212 | 4-yr posted | 4- and 5-yr rates, interpolated for 54 months |
| 42 | $12,727 | $14,415 | 3-yr posted | 3- and 4-yr rates, interpolated for 42 months |
| 30 | $19,555 | $15,018 | 2-yr posted | 2- and 3-yr rates, interpolated for 30 months |
| 18 | $12,146 | $11,085 | 1-yr posted | 1- and 2-yr rates, interpolated for 18 months |
| 6 | $7,764 | $7,764 | 1-yr posted (CIBC uses its 6-month rate; 1-year shown) | 1-yr rate |
Who feels the difference between CIBC and National Bank?
The aggressive pre-payer: $100,000 a year at CIBC vs $50,000 at National Bank
Take a $500,000 5-year fixed at 5.29% at either bank and put the largest lump sum each bank states into it at every anniversary. At CIBC (10%, 15% or 20% by product) you’d have paid it off before renewal, paying $67,523 in interest over the five years; at National Bank (10% a calendar year) you’d owe $166,253 at renewal, paying $95,720. Without lump sums you’d owe $444,528. Kept up, CIBC’s room would clear the mortgage in about 4.8 years against 7.3 at National Bank. Most people won’t prepay this hard; if you will, this is the clause to choose on.
The mover who can’t port: CIBC or National Bank, month by month
Selling with 54 months left would cost $15,595 at CIBC and $18,212 at National Bank, so CIBC is the cheaper exit early in the term; with 6 months left it’s $7,764 against $7,764, and neither bank is cheaper. Waiting from 54 to 6 months left saves $7,831 at CIBC and $10,447 at National Bank. If you might sell mid-term, porting beats both: see the porting row in the term sheet above and ask each bank for its window in writing.

A brand-new mortgage at each bank, broken after two years
A new 5-year fixed for $450,000 at each bank’s own 5-year special, discounted from its own posted rate, broken after 24 months. People usually break when rates have fallen, which is when the IRD bites, so we show both cases:
| CIBC | National Bank | |
|---|---|---|
| Starting rate (5-yr special) | 5.34% | 5.14% |
| Discount from posted | 1.15 pts | 1.00 pts |
| Comparison rate after discount | 4.99% | 5.09% |
| 3 months’ interest | $7,301 | $6,908 |
| Penalty, posted rates unchanged | $7,301 | $6,908 |
| Penalty, posted rates 1 point lower | $18,225 | $14,675 |
Uses each bank’s published rule (see methodology); balance kept at $450,000 for a like-for-like comparison. “—” means the bank publishes no 5-year fixed special to start from (Scotiabank posts none; its specials are variable). Price your own mortgage in the penalty analyzer.
Bring CIBC’s written offer to National Bank (or the other way round) and ask them to beat it on the same term. Then compare the penalty clause, because that’s where these two differ most.
