这个罚款的额度是如何计算呢？简单的说是－－ 3个月的利息。
严格的说是：
greater of { 3 month interest (or) ird }
3个月的利息的利息很好理解，但是什么是ird?
ird = interest rate differential amount
这是definition定义：
Interest Rate Differential Amount (IRD) - An IRD amount is a compensation charge that may apply if you pay off your mortgage principal prior to the maturity date or pay the mortgage principal down beyond the prepayment privilege amount. The IRD amount is calculated on the amount being prepaid using an interest rate equal to the difference between your existing mortgage interest rate and the interest rate that we can now charge when re-lending the funds for the remaining term of the mortgage.
简单的解释就是说：您现在所支付的利息以及您将要转换的利息的差额。
大部分人要做这样的变化是想把高利息转低利息。对银行来说，这就是“损失的利息差额 ” （ird)
银行在计算客户要支付多少罚款是会看3个月的利息和ird. 那个高用那个。 所有的银行
都是采用这样的计算方式。
为什么银行这么“奸诈”呢？ 说道最后还是关于银行的资本营运的成本。
在您签订了一份贷款 (负债liability) 合约时，这对银行来说是它的资产asset.
根据您的承诺，银行将您所支付的利息付给投资人／存款客户，从中
赚取差价。贷款客户中途停止／改变贷款合约，银行如何向投资人／存款客户交代？
所以说罚款是必要的。或者说，大部分的 “罚款”还是流入到投资人／存款客户手中。
并不是银行借机牟利。
followup,
nobody, yes, nobody will pay the penalty for you.
if you switch the mortgage to another bank, the receiving will "not" pay the penalty for you because the profit margin is so thin they cannot afford to do that;
if you just want to change the mortgage to a new/lower rate + stay with your own bank, your own bank will "not" waive the penalty for you; (same reason stated above);
*** if someone says, switch to us and we will penalty for you, they are not telling the truth, they are just playing a trick on you called "cash back" it means they are offering you a rate that is higher then what they should be offering you but lower than what you are paying now. they hope the "differences" will generate enough cash upon funding to cover the penalty. you, the client are paying for the penalty at the end. 羊毛出在羊身上。。。if you don't mind, i can also crunch some numbers and "pay" the penalty for you. for me, i rather give you the best rate i can get. it's the same thing after all.
Interest Rate Differential (IRD) - Mortgage
-The remaining term interest rate differential is calculated based on the amount that the client wants to prepay or payout.
-When calculating IRD, the market rate (current posted rate for the remaining term of the mortgage) will be reduced by the discount the client received on their current mortgage at the time of advance, and will reflect the posted rate at that time.
-If the client was charged a premium, the posted rate for the remaining term is not adjusted.
Example:
-A client received a .50% discount off the posted rate at time of funding. At time of payout the remaining term posted rate will be discounted by .50%.
-If a premium was added to the posted rate at time of funding, then at time of payout the remaining term posted rate will not be adjusted by the premium.
-If the client received a blended rate at time of advance, the discount the client received at funding is the difference between the posted rate on day of funding and the blended client rate. This discount is reported on COB documents and OLMS in the prem/disc field. If the difference is positive, it is reported as a premium.
-This applies to all mortgages advanced, renewed, early renewed, converted, switch-in, or with a built in add-on on, on or after February 1, 2002. OLMS will automatically check the date and calculate the IRD accordingly.

Three Months Interest Calculation
How to Calculate IRD (Estimate Only)
Step 1:
• Mortgage interest rate (expressed as a percentage)_________ (A)
• Posted interest rate for a new mortgage with a term similar to the remaining term in existing mortgage (less any rate reduction received on existing mortgage)_______(B)
• A – B = C, which is the difference between existing interest rate and the current rate (less rate reduction), written as a decimal amount__________ (C)
• Amount client wants to pay off__________ (D)
Step 2:
• Number of months left until the mortgage maturity date_________ (E)
• (C x D x E) divided by 12 = F, estimated interest rate differential amount________(F)
