Something many homeowners are surprised about when they want to sell is what it costs to break their mortgage. While most variable-rate mortgages cost about 3 months of interest to break their mortgage contract, fixed-rate mortgage holders may pay more based on the Interest Rate Differential (IRD) calculation used by their lender.
IRD is calculated differently by each lender and is only applicable the day the lender receives the payout request. The easiest calculation that I've seen is to take the current rate of the mortgage with the length of time remaining in the term. The length of time remaining is important as this covers two variables in the calculation. The interest rate on the current term, is at least as long as the remaining term or shorter.
For example: Two years have passed, exactly three years are remaining, the term rate would be the current three-year rate. If two and half years have passed, the term used would be the two-year term. So if the current rate is 5%, the current 3-year rate is 3.5%, the interest rate used to calculate the penalty would be 1.5% times the outstanding balance, times three years.
Therefore, depending on where you are in your term, this penalty may be in the $1,000s.
Luckily, IRD comes into play when interest rates are dropping and the rate on the term remaining is lower than the rate on the contract (existing mortgage).
