Below we'll explore what you need to know about interest rates as a borrower so you can make smarter decisions with your money.
What Are Interest Rates?
An interest rate is the proportion of a loan that is charged as interest to the borrower, typically expressed as an annual percentage of the loan outstanding. Interest is the money paid regularly at a particular rate for the use of money lent, or for delaying the repayment of a debt.

Lenders give you money because they expect to make a return on their investment. The price of that money is interest. There are many types of loans that produce interest. Some loans have higher interest rates compared to others based on risk and collateralization.
Typically, credit cards and personal loans have the highest interest rates because they are unsecured by any collateral. Conversely, car and mortgage loans offer the lowest interest rates because they are secured by valuable collateral.
Other factors affecting the interest rate you will pay include your credit history, income level, expenses, and other factors affecting your perceived risk of default.
Long-Term Versus Short-Term Loans
Interest rates are also influenced by the length of the loan term.
For example, A 30 year mortgage will require a higher interest rate than a comparable 15 year mortgage. This compensates the lender for what is known as duration risk. In other words, the longer the loan term, the greater the risk that inflation and/or changes in interest rates will reduce the value of that loan.
Conversely, the shorter the loan term the lower your interest rate will be to reflect the reduced duration risk.
Other Factors Affecting The Interest Rate
Sometimes there are special features in your loan that could affect the interest rate.
For example, if the lender allows you to make extra payments so that you can pay off your loan anytime without penalty then this will reduce the total expected value of the loan. The lender will then calculate a higher interest rate to offset this prepayment risk.
Also, the amount of money available for borrowing can impact interest rates. It is a simple supply/demand equation. If the demand for loans is greater than supply then the interest rates will be higher. If there are not many people applying for loans and there is plenty of money to lend then interest rates will decline to attract more borrowers.
The government also dictates the prevailing short-term interest rate based on economic conditions. However, long-term interest rates are determined by market forces and are not controlled by the government.
Interest rates are one of the most important factors to consider when you apply for a loan. It's one of the four relevant loan terms that this interest rate calculator will figure for you.
If you're taking a loan, it's also wise to figure out all the conditions surrounding the loan before you sign on the dotted line.
