Introduction to Bonds
Learn what bonds are, how they work, and why they are considered safer investments than stocks.
Definition
- Face Value (Par Value): The amount you will receive when the bond matures (typically 1000 dollars)

Worked Examples
You buy a bond with a face value of 1000 dollars and a coupon rate of 6%. How much interest will you receive each year?
Identify the values
Face Value = 1000 dollars, Coupon Rate = 6% = 0.06 → Values identified
Apply the formula
Annual Interest = Face Value Coupon Rate →
Calculate
→ 60 dollars per year
Answer: You will receive 60 dollars in interest each year.
Common Mistakes
Confusing coupon rate with total return
Why it's wrong: A 5% coupon rate means 5% of the face value per year, not 5% of your total investment return.
Correct: The coupon rate tells you the annual interest payment as a percentage of face value. Total return also depends on how long you hold the bond.
Forgetting that face value is returned at maturity
Why it's wrong: Students sometimes think the interest payments are all they get, forgetting they also get their principal back.
Correct: At maturity, you receive both your final interest payment AND the full face value. Your total return = all coupon payments + face value.
Using the wrong decimal for percentage
Why it's wrong: Writing 5% as 5 instead of 0.05 in calculations leads to answers that are 100 times too large.
Correct: Always convert percentages to decimals: 5% = 5/100 = 0.05

Practice Problems
15 problemsWhat do you receive regularly when you own a bond?
Why It Matters
- Predictable Income: Unlike stocks, bonds pay regular, fixed interest payments
- Lower Risk: Bonds are generally safer than stocks because you are guaranteed your principal back (unless the issuer defaults)
- Diversification: Bonds often move opposite to stocks, providing stability during market downturns
- Real-World Uses:
- - Governments issue bonds to fund roads, schools, and infrastructure
- - Companies issue bonds to expand their businesses
- - Retirees often invest in bonds for steady income
Real World Applications
Government Savings Bonds
Many governments issue savings bonds that citizens can buy to help fund public projects while earning interest.
Example:
A 10-year government bond with 1000 dollars face value at 3% pays 30 dollars per year, totaling 300 dollars in interest over 10 years.
Your grandparent gives you a 500 dollar savings bond with a 4% coupon rate that matures in 5 years.
How much total interest will you earn by maturity?
Step 1: Write the mathematical expression
Calculate: Face Value Rate Years
Corporate Bonds for Expansion
Companies issue bonds to raise money for expansion, new equipment, or other business needs.
Example:
A tech company issues a 5-year bond at 6% to fund a new factory. Investors receive 60 dollars annually per 1000 dollar bond.
A company offers a 2000 dollar bond with 5% interest for 7 years.
What is the total amount you will receive at the end (interest + face value)?
Step 1: Write the mathematical expression
Total = Face Value + (Annual Interest Years)
Key Takeaways

- 2Face value (par value) is the amount returned to you when the bond matures
- 3Coupon rate is the annual interest rate, and coupon payment is the actual interest received

- 5Total Interest = Annual Interest times Number of Years
- 6Bonds are generally safer than stocks but offer lower potential returns
