IRD Explained (Plain English)
The Interest Rate Differential (IRD) is a common penalty method on Canadian fixed-rate mortgages. In general terms, it can apply when:
-
You break your mortgage early, and
-
Interest rates have dropped since you took the mortgage, meaning your lender may “lose” interest revenue if they re-lend at a lower rate.
Penalty outcomes vary significantly by lender and timing, which is why monitoring matters

Interest Rate Differential (IRD):
-
The Interest Rate Differential (IRD) on a Canadian fixed-rate mortgage is a type of penalty that may be charged to a borrower who decides to pay off or refinance their mortgage before the end of its term. The IRD is calculated when the interest rates have dropped since the time the mortgage was taken out, and the lender stands to lose interest income if the mortgage is paid off early and the funds are then lent out at a lower current rate.
-
The IRD is essentially the difference between:
-
The interest rate on your existing mortgage: This is the rate you agreed to pay when you signed your mortgage contract.
-
The current interest rate that the lender can charge today for a mortgage term similar to your remaining term: This is usually based on the rate the lender could earn if they were to re-lend the funds at current market rates for the remaining duration of your original term.
-
-
-
The formula for calculating the IRD can vary between lenders but generally involves the following steps:
-
Determine the remaining balance on your mortgage.
-
Calculate the difference between your mortgage's interest rate and the current market rate for a term similar to your remaining term.
-
Multiply this rate difference by the remaining balance.
-
Multiply the result by the remaining term of your mortgage (in years or months, depending on how the lender calculates it).
