Whether you’re a financial expert or just starting to learn about the economy, this article is designed to give you a thorough understanding of interest rates and how they affect our lives. In this guide, we’ll cover the basics of interest rates, how they’re calculated, and their impact on the economy. We’ll also include some frequently asked questions and tables to help illustrate key concepts. Let’s get started!
What are Interest Rates?
Interest rates are the cost of borrowing money. They represent the percentage of the loan that is charged to the borrower as compensation for the lender’s risk and opportunity cost. Put simply, interest rates are how lenders make money off of loans.
Interest rates can be either fixed or variable. A fixed interest rate remains the same for the duration of the loan, while a variable interest rate can change over time based on market conditions.
How are Interest Rates Calculated?
Interest rates are determined by a variety of factors, including inflation, economic growth, and monetary policy. Inflation is the rate at which prices for goods and services increase over time. When inflation is high, lenders typically charge higher interest rates to compensate for the decreased purchasing power of their loaned money. Economic growth also impacts interest rates, as lenders are more willing to lend money during times of growth when there is less risk of default. Finally, monetary policy set by central banks can influence interest rates by adjusting the supply and demand for money in the economy.
The formula for calculating interest rates is:
| Symbol | Explanation |
|---|---|
| r | Interest Rate |
| i | Annual Interest Payment |
| P | Principal |
Where:
r = (i / P) x 100
This formula can be used to calculate the interest rate for any loan, including mortgages, car loans, and credit cards.
What is the Federal Funds Rate?
The Federal Funds Rate is the interest rate at which banks lend to each other overnight to meet reserve requirements set by the Federal Reserve. The Federal Reserve sets a target for the Federal Funds Rate, and adjusts it as needed to achieve its monetary policy goals. Changes in the Federal Funds Rate can impact other interest rates, such as those for mortgages and credit cards.

| 2000 | 6.50% |

How do Interest Rates Affect the Economy?
Interest rates have a significant impact on the economy and financial markets. When interest rates are low, borrowing is cheaper, which can stimulate economic growth. Lower interest rates can also lead to higher inflation, as people are more likely to spend money when credit is cheap and available.
On the other hand, high interest rates can slow down economic growth by making borrowing more expensive. High interest rates can also lead to lower inflation, as people are less likely to spend money when credit is expensive and scarce.
What is the Prime Rate?
The Prime Rate is the interest rate that banks charge their most creditworthy customers. It is typically used as a benchmark for other interest rates, such as those for mortgages and credit cards.
The Prime Rate can change based on market conditions and is often influenced by the Federal Funds Rate. The table below shows the historical Prime Rate from 2000 to 2020:
