Variable Interest Rate

Definition and meaning of Variable Interest Rate in real estate.

A variable interest rate is an interest rate on a loan that fluctuates over time in response to changes in a designated market index.

In more detail

Loans with variable interest rates typically start with a fixed rate for an initial period, after which the rate adjusts periodically based on market conditions. These rate adjustments are tied to a benchmark index, such as the Secured Overnight Financing Rate, plus a lender margin.

Borrowers choose variable rates because they often offer lower initial monthly payments compared to fixed-rate loans, but they carry the risk of payments increasing if interest rates rise.

Frequently asked questions

What is the difference between a variable interest rate and an adjustable interest rate?

The terms are generally used interchangeably in consumer lending, though variable rate often refers to short-term changes while adjustable rate is common in long-term mortgages.

Can my variable interest rate increase without limit?

Most variable-rate loans feature interest rate caps, which limit how much the rate can increase during a single adjustment period and over the lifetime of the loan.
