How Interest Rates Work

A Primer for Beginners

Understanding interest rates is crucial for anyone looking to manage finances effectively. Whether you’re saving money or borrowing it, interest rates determine how much you earn or owe over time. At Texas Bay Credit Union, we aim to help you grasp these financial concepts so you can make informed decisions about your money.

What Are Interest Rates?

In the simplest terms, an interest rate is the cost of borrowing money or the reward for saving it. It’s usually expressed as a percentage of the principal—the amount of money you originally borrowed or saved. Interest rates affect various aspects of personal finance, including savings accounts, personal loans, auto loans, mortgages, and credit cards.

• For Savers: Interest rates determine how much your money will grow in a savings account, certificate of deposit (CD), or similar investment.
• For Borrowers: Interest rates dictate how much you’ll pay over the life of a loan or how quickly credit card debt can accumulate.

Types of Interest Rates

Interest rates can be categorized into several types, depending on how they’re calculated and applied.

1. Fixed Interest Rates

A fixed interest rate stays the same for the entire term of a loan or investment. This makes it easy to predict your monthly payments or interest earnings.

• Example: If you take a 5-year personal loan at a fixed 5% interest rate, your monthly payments won’t change throughout the loan term.

Advantages of Fixed Interest Rates:

• Predictable payments or returns
• No surprises due to rate fluctuations
• Ideal for long-term budgeting

Disadvantages of Fixed Interest Rates:

• May be higher than initial variable rates
• No benefit from falling rates in the market

2. Variable Interest Rates

Variable interest rates can fluctuate over time based on changes in a benchmark interest rate, such as the prime rate or the federal funds rate.

• Example: An adjustable-rate mortgage (ARM) often starts with a fixed rate for a set period, after which the rate can change periodically.

Advantages of Variable Interest Rates:

• Initial rates may be lower than fixed rates
• Potential savings if rates decrease over time

Disadvantages of Variable Interest Rates:

• Payments can increase unexpectedly
• Uncertainty in long-term financial planning

How Interest Rates Are Set

Interest rates are influenced by several factors, including:

1. Federal Reserve Policies

The Federal Reserve, often called “The Fed,” plays a major role in setting interest rates in the U.S. It adjusts rates primarily to control inflation and stimulate or slow down economic growth. For instance:

• When the economy is slow: The Fed may lower interest rates to encourage borrowing and spending.
• When inflation is high: The Fed may increase rates to curb spending and borrowing.

2. Economic Conditions

General economic factors like employment rates, consumer spending, and business investments also affect interest rates. During times of economic growth, rates might rise to prevent overheating. Conversely, during downturns, rates might be reduced to promote borrowing and spending.

3. Inflation

Inflation measures how quickly prices for goods and services rise over time. Higher inflation often leads to higher interest rates, while low inflation usually correlates with lower rates.

4. Credit Risk

Lenders assess the risk of lending money to different borrowers. If a borrower has a high credit risk (e.g., a low credit score), they may be charged a higher interest rate to offset the risk. Conversely, borrowers with good credit scores often enjoy lower interest rates.

How Interest Rates Impact Savings

For savers, interest rates play a crucial role in determining how much money you can earn over time.

1. Savings Accounts and Certificates of Deposit (CDs)

• Savings Accounts: These accounts usually offer a relatively low interest rate, but they provide liquidity and safety for your money.
• Certificates of Deposit (CDs): CDs often offer higher interest rates than regular savings accounts because you agree to leave your money in the account for a set period.

Example: If you deposit $1,000 in a CD with a 2% interest rate for one year, you’ll earn $20 in interest at the end of the term.

2. Compound Interest

Compound interest is one of the most powerful concepts in finance. It’s the interest calculated on both the initial principal and the accumulated interest from previous periods. The more frequently interest is compounded (e.g., daily, monthly), the more you’ll earn.

Example: Let’s say you have $1,000 in a savings account with a 5% annual interest rate compounded monthly. Thanks to compounding, after one year, you’d earn about $51 in interest, not just $50.

At Texas Bay, interest on CDs is paid monthly; therefore compounding by the end of the term. This is known as the Annual Percentage Yield or APY.

How Interest Rates Affect Borrowing

When it comes to borrowing, interest rates determine the cost of loans and credit.

1. Loans

Loans, whether personal, auto, or mortgage, come with interest rates that affect your monthly payments. Higher rates mean higher payments, while lower rates can make borrowing more affordable.

Example: A 30-year mortgage for $200,000 at a 4% interest rate will result in lower monthly payments compared to the same mortgage at a 5% interest rate.

2. Credit Cards

Credit cards often have variable interest rates, which can change based on broader economic trends. It’s important to pay off credit card balances as quickly as possible to avoid high-interest costs.

Example: If you have a credit card balance of $1,000 with an 18% annual interest rate and make only the minimum payment each month, it could take years to pay off the balance while accruing significant interest charges.

Tips for Managing Interest Rates

1. Check Your Credit Score: A higher credit score can help you qualify for lower interest rates on loans and credit cards.
2. Refinance When Possible: If rates drop, consider refinancing loans or mortgages to take advantage of lower rates.
3. Consider the Total Cost: Look beyond the interest rate alone; also consider fees, loan terms, and other factors that affect the total cost of borrowing or saving.
