## Definition

A fixed interest rate loan is a loan where the interest rate doesn’t fluctuate during the fixed rate period of the loan. This allows the borrower to accurately predict their future payments. Variable rate loans, by contrast, are anchored to the prevailing discount rate.

## Fixed Interest Rate Loan

A fixed interest rate loan is a loan in which the interest rate doesn’t fluctuate during the fixed rate period of the loan. This allows the borrower to accurately predict their future payments. The borrower will pay a set amount of interest on a loan or line of credit. Unlike a variable interest rate loan, in which the interest rate can go up or down in response to changes in the prime rate or other index rate, a fixed rate remains the same unless the lender changes it. A fixed interest rate is based on the lender’s assumptions about the average discount rate over the fixed rate period. For example, when the discount rate is historically low, fixed rates are normally higher than variable rates because interest rates are more likely to rise during the fixed rate period. Conversely, when interest rates are historically high, lenders normally offer a discount to borrowers to fix their interest rate over time, as rates are more likely to fall during the fixed rate period.

## How Does a Fixed Interest Rate Work?

With a fixed rate loan, youll know exactly how much each monthly payment will be, as well as how much it will cost you overall to pay off the loan based on the agreed upon rate. On the flipside, a variable interest rate loan can fluctuate; meaning youll have no way of knowing if/when your payments will go up, down, or remain the same during the life of the loan. Borrowers do not always have the option of choosing between fixed and variable rate loans. Lenders must disclose where the interest rate on a loan is fixed or variable, as well as what the interest rate will be, prior to agreeing to the loan terms.

## Can I switch from a variable to a fixed interest rate?

Depending on the lender, and the type of loan, you may be able to refinance your loan from a variable interest rate to a fixed interest rate (or vice versa). By refinancing from a variable interest rate loan to a fixed interest rate, especially when rates are low, you can lock in a new, hopefully lower, interest rate for the remainder of the loan terms.

## Pros and Cons of a Fixed Interest Rate

The benefit of a fixed interest rate loan in the security of knowing that the changing marketing conditions, an increase in the prime rate or other index rate, won’t trigger a change in your fixed interest rate. The negative of the above, is that the opposite rings true. Even if index rates go way down, and your lenders lower their variable rates, the interest on a fixed-rate loan will stay the same. Choosing between a fixed interest rate and a variable interest rate comes down to your comfort level with risk. If you like the security of a loan payment plan that will not change over the length of the loan, go with a fixed interest rate.
