Interest rate is the fee charged by the lender to the borrower, usually expressed as a percentage of the principal (i.e., the loan amount). The interest rate on a loan is generally calculated annually and expressed as an annual percentage rate (APR).

Interest rates also apply to savings accounts or time deposits (CDs). In this case, the bank or credit union pays the account holder a percentage of the funds deposited. Annual Percentage Yield (APY) refers to the interest earned on these deposit accounts.
Interest is essentially a fee for the borrower to use the asset. Borrowed assets can include cash, consumer goods, vehicles and real estate. Therefore, interest rates can be thought of as the "cost of funds" - the higher the interest rate, the more expensive it is to borrow the same amount.
The interest rate applies to most loan or borrowing transactions. Personal borrowing is used to buy a home, finance a project, start or grow a business, or pay for college. Businesses use loans to finance capital projects and expand operations, such as purchasing fixed assets such as land, buildings and machinery. Borrowed money is usually repaid in a lump sum or in installments on an agreed date.
For loans, the interest rate is applied to the principal, which is the amount of the loan. The interest rate is the cost of debt for borrowers and the rate of return for lenders. The amount repaid is usually higher than the amount borrowed because the lender needs to compensate for any loss in use of the funds over the life of the loan. During this time, the lender could have invested the money and made a profit. The difference between the total payment and the original loan is the interest charged.
When a borrower is considered a low risk by the lender, a lower interest rate will generally be charged; if the borrower is considered a high risk, a higher interest rate will be charged, resulting in a higher loan cost.
Important: Risk is usually assessed when lenders look at a potential borrower's credit score, so it's crucial to have a good credit score if you want to get the best loan.
Suppose you borrow US300,000 plus (4% x US300,000 + US312,000 to the bank.
The above example is based on the annual simple interest formula:
If the borrower only borrows the loan for one year, he or she will have to pay $12,000 in interest at the end of the year. If the loan is a 30-year mortgage, the interest payment is:
Simple interest = 360,000
An annual interest rate of 4% translates into annual interest payments of 12,000 x 30 years = $360,000 in interest, which explains how banks make money on loans, mortgages, and other types of lending.
Some lenders prefer to use compound interest, meaning the borrower pays more in interest. Compound interest, also known as interest on interest, applies to the principal as well as interest accumulated in previous periods. The bank assumes that at the end of the first year, the borrower owes the principal plus that year's interest; at the end of the second year, the borrower owes the principal plus the first year's interest, plus the first year's compound interest.
The interest owed when compound interest is calculated is higher than the interest owed under the simple interest method. Interest is charged each month on the principal including interest accumulated in previous months. For shorter time periods, interest calculations are similar for both calculations. However, as the length of the loan increases, the difference in calculations between the two methods increases.
Using the example above, the total interest on a 673,019 at the end of 30 years.
Compound interest can be calculated using the following formula:
Let’s look at another example. The principal loan is US1,576.25:
Compound interest is beneficial when saving money using a savings account. The interest earned on the account is compounded as compensation to the account holder for allowing the bank to use the deposited funds.
For example, if you deposit 300,000 of that toward your mortgage. For this, the bank will pay you 5% interest per year. Therefore, the bank charges 8% interest to the borrower and 5% interest to the account holder, resulting in a net interest rate of 3%. In effect, savers lend money to banks, which in turn provide it to borrowers in exchange for interest.
While interest rates represent interest income to lenders, they constitute a cost of debt to borrowers. When businesses evaluate the cost of borrowing, they compare it to the cost of equity (such as dividend payments) to determine which form of financing is the cheapest. Since most companies choose to borrow debt or issue equity when funding capital, the assessment of the cost of capital is aimed at achieving an optimal capital structure.
Interest rates on consumer loans are often expressed as an annual percentage rate (APR), which is the rate of return required by the lender on borrowed money. For example, credit card interest rates are expressed as APR. In the example above, 4% is the APR on the mortgage. APR does not take into account compound interest during the year.
The annual percentage yield (APY) is the interest rate a bank or credit union earns on a savings account or CD, which takes into account compound interest.
The interest rates charged by banks are affected by a variety of factors, such as the economic situation. A country's central bank (such as the Federal Reserve System in the United States) sets the interest rate, and each bank determines the APR range it offers based on this interest rate. When central banks set higher interest rates, the cost of debt rises, dampening borrowing and consumer demand. Interest rates tend to rise with inflation.
To curb inflation, banks may raise reserve requirements, leading to a tightening of the money supply, or an increase in demand for credit. In an economy with high interest rates, people tend to save because they can earn more from their savings. Stocks have been dragged down as investors prefer to tap their high-yielding savings rather than invest in lower-yielding stocks. Businesses are also restricted in their search for capital funding, causing the economy to shrink.
During periods of low interest rates, the economy tends to be stimulated because borrowers can obtain loans at low fees. Because interest rates on savings are low, businesses and individuals are more likely to spend and buy riskier investment vehicles, such as stocks. Such consumption stimulates the economy and injects vitality into capital markets, promoting economic expansion.
Although the government favors lower interest rates, this ultimately leads to market imbalances where demand exceeds supply, triggering inflation. When inflation occurs, interest rates increase, which may be related to Walras' law.
6.90%: The average interest rate for a 30-year fixed-rate mortgage in February 2024. This is up from 6.0% a year ago and 3.89% two years ago.
Systemic racism in the United States persists despite laws like the Equal Credit Opportunity Act (ECOA) prohibiting discriminatory lending practices.
Research evidence shows that white people have a higher chance of being approved for a mortgage. According to data reported under the Home Mortgage Disclosure Act, 16.4%, 11.1%, and 9.2% of Black, Hispanic, and Asian applicants, respectively, were denied conventional mortgages in 2022. The rejection rate for white applicants was much lower, at only 5.8%. There is also data showing that race affects interest rates. Mortgage data from 2018 and 2019 from Realtor.com found that home buyers in areas with predominantly black neighborhoods received mortgage rates that were 13 basis points higher than those in white neighborhoods.
Other sources, including Harvard University and the Urban Institute, have confirmed the existence of mortgage rate discrimination. In 2022, the agencies claimed that the average black homeowner paid an interest rate 33 basis points higher than the average white homeowner and paid about $250 more in interest per year.
Not everyone agrees with these findings. A study by Federal Reserve economists showed no preference was given to any race, prompting the authors to speculate that disparities reported elsewhere may be due to black and Hispanic borrowers tending to choose slightly higher interest rates in exchange for lower upfront costs.
The Fed believes discrimination has improved, thanks in part to automatic underwriting and stricter enforcement of the Fair Housing Act and the Equal Credit Opportunity Act.
The interest rate depends on default risk and opportunity cost. Longer-term loans and debt are inherently riskier because the borrower has a longer chance of defaulting. At the same time, the opportunity cost is greater over a longer period because the principal is locked up during this period and cannot be used for other purposes.
The Federal Reserve, like other central banks around the world, uses interest rates as a monetary policy tool. By raising borrowing costs for commercial banks, the central bank is able to influence many other interest rates, such as personal loans, business loans and mortgages. This generally makes borrowing more expensive, reducing demand for funds and easing an overheating economy. Conversely, lowering interest rates makes it easier to borrow funds, thereby stimulating consumption and investment.
A bond is a debt instrument that typically pays a fixed rate of interest over its life. If the prevailing interest rate is 5%, a bond with a price of 50 per year in interest. If interest rates rise to 10%, the newly issued bond will pay double interest, or 1,000 of face value. Existing bonds paying only 10 in interest per 50 will be highly sought after and its price will be pushed higher.
The interest rate is the cost of debt for borrowers and the rate of return for lenders. When you take out a loan, you pay an additional fee to the entity that lent the funds as compensation. Likewise, a financial institution may reward you if you keep funds in a savings account because it can use the funds to provide more loans to its customers.
These fees or payments are called interest and are calculated at a predetermined rate.
