An interest rate is a cost of using money. It is the amount a lender charges a borrower for using their money. It is usually shown as a percentage. This percentage is applied to the amount of money borrowed or saved.
Types of Interest Rates
There are different types of interest rates. Let’s discuss a few common types.
Fixed Interest Rate
A fixed interest rate stays the same over the loan or savings period. It does not change. This can be good for planning. You know what to expect each month.
Variable Interest Rate
A variable interest rate can change over time. It might go up or down. This depends on the market or other factors. It can make payments higher or lower.
Simple Interest Rate
Simple interest is calculated on the principal amount only. The principal is the original amount of money. This means you pay interest only on the initial amount borrowed.
Compound Interest Rate
Compound interest is calculated on the principal amount and also on any interest earned. This means you pay interest on interest. It can make the total amount owed grow faster.
How Interest Rates Work
Interest rates work based on the type of loan or savings. Let’s look at some examples.
Interest Rates On Loans
When you borrow money, you usually have to pay it back with interest. The interest rate determines how much extra you pay. Here is a simple example:
| Loan Amount | Interest Rate | Interest Paid | Total Amount Paid |
|---|---|---|---|
| $1,000 | 5% | $50 | $1,050 |
In this example, you borrowed $1,000 at a 5% interest rate. You will pay $50 in interest. The total amount you pay back is $1,050.
Interest Rates On Savings
When you save money, banks may pay you interest. This is like a reward for keeping your money with them. Here is a simple example:
| Savings Amount | Interest Rate | Interest Earned | Total Amount |
|---|---|---|---|
| $1,000 | 2% | $20 | $1,020 |
In this example, you saved $1,000 at a 2% interest rate. You will earn $20 in interest. Your total savings grow to $1,020.

Factors Affecting Interest Rates
Interest rates can change based on several factors. Here are some common ones:
Inflation
Inflation is the rate at which the general level of prices for goods and services rises. Higher inflation usually leads to higher interest rates.
Economic Growth
When the economy grows, interest rates may rise. This is because demand for money increases. More people and businesses want to borrow.
Central Bank Policies
Central banks, like the Federal Reserve, set key interest rates. These rates influence other interest rates in the economy. They may raise or lower rates to control inflation and stabilize the economy.
Credit Score
Your credit score affects the interest rate you get. A higher credit score usually means a lower interest rate. Lenders see you as less risky.
Why Interest Rates Matter
Interest rates matter because they affect our daily lives. They influence how much we pay on loans and how much we earn on savings.
Borrowing Money
If interest rates are high, borrowing money costs more. This can affect big purchases like homes and cars. It can also make credit card debt more expensive.
Savings
