What is a Blended Rater?
A blended rate is an interest rate that combines the rate from an existing mortgage with the rate of a new mortgage when refinancing or increasing the loan amount.
Why Blended Rates Matter in Real Estate
In Canada, lenders use blended rates when a borrower wants to access more funds mid-term—typically through refinancing, porting, or adding to their mortgage. Rather than paying a prepayment penalty to break the mortgage, a blended rate allows borrowers to combine rates.
Blended rates are calculated using:
- The current interest rate on the existing mortgage
- The new rate being offered
- The proportion of each mortgage amount
- Avoid prepayment penalties
- Access equity for renovations or investments
- Maintain flexibility while locking in new funds
Example of a Blended Rate
A homeowner with a $300,000 mortgage at 2.8% blends in $100,000 at a new 5.2% rate, resulting in a combined rate of 3.5% without breaking their mortgage.
