The impact of interest can be seen in our everyday lives, from the interest we pay on loans for big purchases like homes and cars, to the interest we earn on savings accounts and investments.
In this article, we will define interest and discuss how it works and its impact on our everyday lives.
Defining Interest
To put it simply, interest is the cost of borrowing money. Interest is a percentage of the amount borrowed or invested, typically expressed as an annual rate, that is charged or paid for the use of money over a certain period of time.
It is the cost of borrowing money or the return on an investment. It can be calculated on a variety of financial products such as loans, mortgages, credit card balances, and savings accounts. In a nutshell, interest is the price of money.

Why Is Interest Important?
Interest is important because it’s basically extra money that you can earn or pay on top of the money you borrowed or invested. For example, if you put your money in a savings account, the bank will pay you interest, which is a little extra money on top of what you originally saved. This can help your money grow over time.
On the other hand, if you borrow money, like from a credit card or a loan, you will have to pay interest on top of the money you borrowed. This means you’ll have to pay back more than you borrowed.
Interest can also be affected by different factors such as inflation, credit score, and the type of investment or loan.
In short, Interest is important because it can help your money grow, but it can also make borrowing more expensive. So it’s important to understand how interest works and how it can affect your finances, whether you’re saving, investing, or borrowing money.
Interest can be either simple or compound. Here is the difference:
Simple Vs. Compound Interest
Simple interest and compound interest are two different ways to calculate how much interest you earn on an investment or how much interest you pay on a loan.
Simple interest is when you just multiply the amount you borrowed or invested (called the “principal”), the interest rate, and the number of years you have it for. For example, if you borrow $1000 at a 5% interest rate for one year, you would pay $50 in interest. The formula for simple interest is: I = Prt, where ‘I’ is the interest earned, ‘P’ is the principal amount, ‘r’ is the interest rate, and ‘t’ is the number of time periods.
Compound interest is different because it adds the interest you earn each year to the principal, and then calculates the interest for the next year based on that bigger number. So, the interest you earn each year gets bigger and bigger. For example, if you invest $1000 at a 5% interest rate for one year with compound interest, you would actually earn $25.51 in interest.
This means that the interest earned in each subsequent period is based not only on the original principal amount, but also on the accumulated interest from all previous periods. The formula for compound interest is: A = P(1 + r)^t, where ‘A’ is the final amount including interest, ‘P’ is the principal amount, ‘r’ is the interest rate, and ‘t’ is the number of time periods.
One thing that you will always see accompanying APY rates is the compounding period. This period is important as it tells us how often the interest is worked out. Available options here include daily, weekly, monthly, quarterly, and yearly.
Most of the time, it will be once a day. The best compounding period is daily (if you’re investing and earning interest), and the worst is yearly. This is because the more compounding periods we have, the more interest is added to the original capital when we compound.

Fixed Vs. Variable Interest
Interest can be fixed or variable. Interest that is fixed stays the same for the whole term. Interest that is variable can go up or down during the term.
When a bank or other financial institution gives a rate, it doesn’t just make it up out of nothing. Instead, it is based on the Federal Reserve rate, which is released every day. The Federal Reserve sets a target for the federal funds rate, which is the interest rate at which banks can borrow money from each other overnight. This rate is used as a benchmark for other interest rates, such as the prime rate, which is the rate at which banks lend money to their most creditworthy customers.
The Federal Reserve can raise or lower interest rates as a way to influence the economy. When the Fed raises interest rates, it becomes more expensive for businesses and consumers to borrow money, which can slow down economic growth. Conversely, when the Fed lowers interest rates, it becomes cheaper to borrow money, which can stimulate economic growth
When you get a loan or open a CD at a bank, you might be able to choose between a fixed rate and a variable rate.
A fixed rate gives you peace of mind because you will always know how much you owe (down to the last cent). On the other hand, if the rate goes down, you might not save as much. When you choose a variable rate, the opposite is true. You don’t know for sure how much you’ll end up paying, so you might save money or end up paying more.

How Is The Interest Rate Set?
Interest rates are a crucial aspect of the economy and are determined by a variety of factors. As previously mentioned, the Federal Reserve, as the central bank of the United States, plays a major role in determining interest rates by setting the target for the federal funds rate, which is the rate at which banks can borrow money overnight from each other.
The Fed can raise or lower this rate in order to influence the economy. When the Fed raises interest rates, it becomes more expensive for businesses and consumers to borrow money, which can slow down economic growth and decrease inflation. Conversely, when the Fed lowers interest rates, it becomes cheaper to borrow money, which can stimulate economic growth and increase inflation.
Inflation is another important factor that determines interest rates. Inflation is the rate at which the prices of goods and services in an economy are rising. When inflation is high, the Fed will typically raise interest rates to help curb it, as high inflation can lead to economic instability. However, when inflation is low, the Fed may lower interest rates to help stimulate economic growth.
The level of supply and demand for credit also plays a role in determining interest rates. When demand for credit is high, lenders can charge higher interest rates to borrowers. This is because the demand for loans is high, so lenders can charge more for the loan. Conversely, when demand for credit is low, lenders may need to lower interest rates to attract borrowers. This is because the demand for loans is low, so lenders have to offer lower rates to entice borrowers.
Finally, global events can also have an impact on interest rates. Political and economic instability, natural disasters, acts of war, and other unexpected events can cause uncertainty in the market, leading to fluctuations in interest rates.
Overall, interest rates are determined by a complex interplay of economic, financial, and political factors, and can fluctuate depending on the current state of the economy and global events. Understanding how interest rates are determined can help individuals and businesses make informed decisions about borrowing and investing.

A fixed interest rate means the rate stays the same for the entire loan term, while a variable interest rate can change over time. Variable rates tend to start lower but can go up or down depending on the market.
Interest rates can affect the stock market in a few ways. When interest rates are low, it can make stocks look more attractive because they offer better returns than bonds. But when rates are high, it can make stocks look less attractive and cause the market to drop.
