What is a Fixed Rate and it's Advantages and Disadvantages

What is a Fixed Rate?

A fixed interest rate is an interest rate that remains the same throughout the specified term of the loan. Typically fixed rates are agreed upon between 1 to 5 years.

This means that the borrower will pay the same interest rate on the loan for the entire fixed period even if the market rates change. This contrasts with adjustable-rate (floating) loans, in which the interest rate can change over time based on changes in market interest rates.

Advantages of a fixed interest rate:

  • Predictability: Budgeting and financial planning becomes easier as borrowers know exactly what their interest rate and monthly payment will be for the life of the loan.                       
  • Stability: A fixed interest rate provides stability in an unpredictable interest rate environment, protecting borrowers from unexpected increase in loan costs. 
  • Rate: Fixed rates are typically lower than adjustable (floating) rates, meaning borrowers may pay less in interest over the life of the loan.

Disadvantages of a fixed interest rate:

  • Limited flexibility: Borrowers may be locked into a higher interest rate if rates fall after the loan is taken out.           
  • Lump repayments: Many lenders will limit extra 'lump' repayment amounts during a fixed period.

  • After checking out the great reviews we decided to get in touch with Scott to help us navigate the landmines of home loans as a first home buyer. We went in with little knowledge and have left feeling way more confident with the whole process. Scott provided exceptional information, help and guidance and his step by step guide made the whole thing seamless. It didn't take long to get the ball rolling and before long we were putting the final touches on the home loan. We can't recommend his service enough and would encourage everyone to get in touch with him for mortgage advice.
