Interest rate is a common term that has many definitions. In the most basic sense, an interest rate represents the cost of a loan, or the accrued cost of borrowing money. An interest rate is also the cost of the lender’s service. Because the business of lending money is risky, an interest rate protects the lender. Also, because lending requires monetary deferment in the present, without the interest rate, most lenders wouldn’t be willing to cut spending, save and lend money. The interest rate is available in many forms. No matter if you are a borrower or a lender, it’s very important to be knowledgeable about your interest rate options.   

Because the loan lender always risks the possibility of the borrower not paying the loan, an interest rate acts as risk compensation for the lender. Inflation also plays a major role with the interest rate. When the lender loans money in the present, the cost of services and goods will rise by the time the borrower pays back the loan. The interest rate accounts for this future inflation of the market.    

The interest rate is the price borrowers must pay to obtain immediate money. The interest rate enables the borrower to afford commodities now, rather than having to save money and buy in the future. The mortgage interest rate market is a prime example of how an interest rate caters to immediate needs. If a buyer agrees to a home mortgage that they cannot afford in full, they can utilize the interest rate as a means to loan money, and pay the mortgage over time.

  The interest rate exists based on the nature of supply and demand. The monetary level of the interest rate is directly related to supply and demand in the market. The risk factor also is a big determinant of the interest rate level. The risk factor represents the probability of the borrower paying the amount of the loan. If there isn’t a good chance the borrower will repay the loan, the interest rate level will be high. But, if it’s liable the borrower will pay the loan in full, the interest rate level will be lower. Secured loans also lower the level of the interest rate. For secured loans, where lenders are guaranteed additional collateral if the borrower doesn’t repay the loan, the collateral accounts for the level of the interest rate.    

The interest rate is paramount to the mortgage industry. Because many people want to own homes, but lack the funds to pay for the entire mortgage; an interest rate enables more people to finance a mortgage and own their own home. An interest rate is also a very lucrative factor for the lender. The interest rate is the major source of income for the lender. Thus, the interest rate simultaneously helps the borrower, the lender, and the growth of the real estate market.
