🏦 Bond Fundamentals: Your Ticket to the Lending Club
Imagine you’re a kid with a piggy bank full of savings. Your friend needs $100 to buy a bike, and they promise to pay you back $105 next year. Congratulations—you just made your first “bond” deal!
🎯 What is a Bond?
A bond is simply an “I Owe You” (IOU) note.
When you buy a bond, you’re lending money to someone—a company, a city, or even the government. In return, they promise to:
- Pay you interest (like a thank-you for lending)
- Give your money back on a specific date
🍕 The Pizza Party Analogy
Think of bonds like this:
Your school wants to throw a pizza party but needs $1,000. They ask 10 students to each lend $100. In return, the school promises:
- To give back $100 to each student in one year
- Plus $5 extra as a “thank you” (that’s the interest!)
That’s exactly how bonds work!
| Real World | Pizza Party |
|---|---|
| Bond Issuer | Your School |
| Bondholder | You (the lender) |
| Principal | $100 you lent |
| Interest | $5 thank-you money |
💰 Face Value vs Market Value
Face Value (Par Value)
Face value is the “sticker price”—the amount printed on the bond.
Like a $100 gift card that says “$100” on it, a bond’s face value is the amount you’ll get back when the bond matures (ends).
Example: A bond with $1,000 face value means you’ll receive exactly $1,000 when it matures.
Market Value
Market value is what people are actually willing to pay for the bond TODAY.
Here’s the twist: Just like a limited-edition toy might sell for MORE than its store price, bonds can trade for more or less than their face value!

🎮 Video Game Trade-In Analogy
- Face Value = The original price tag ($60 game)
- Market Value = What GameStop offers you today ($25 or $40, depending on demand)
| Term | What It Means | Example |
|---|---|---|
| At Par | Market = Face | Pay $1,000 for $1,000 bond |
| Premium | Market > Face | Pay $1,050 for $1,000 bond |
| Discount | Market < Face | Pay $950 for $1,000 bond |
🎟️ Coupon Rate: Your Annual Thank-You Payment
The coupon rate is the percentage of interest you earn each year.
Why “coupon”? In the old days, bonds had actual paper coupons attached. You’d clip one off and exchange it for your interest payment! ✂️
How to Calculate It
Annual Interest Payment = Face Value × Coupon Rate
Example:
$1,000 × 5% = $50 per year
🍪 The Cookie Jar Promise
Imagine your grandma gives you a cookie jar with $100 inside. She promises:
“Every year on your birthday, I’ll add 5 cookies to the jar.”
- Cookie Jar = Face Value ($100)
- 5 Cookies = Coupon Payment ($5)
- 5% per year = Coupon Rate
Important: The coupon rate NEVER changes! It’s locked in forever when the bond is created.
📈 Bond Pricing: The Seesaw Effect
Here’s one of the most important secrets in bond investing:
When interest rates go UP, bond prices go DOWN. When interest rates go DOWN, bond prices go UP.
They move like kids on opposite ends of a seesaw! ⚖️
Why Does This Happen?
Let’s say you bought a bond paying 5%. Then new bonds start paying 7%.
Your 5% bond suddenly looks boring! Nobody wants to pay full price for it anymore. So its market price drops to make up for the lower interest.

🍦 Ice Cream Shop Example
- Your shop sells vanilla for $5
- New shop opens selling chocolate for $3
- Now you must lower your vanilla price to compete!
Same with bonds—older bonds must become “cheaper” (lower price) to compete with newer, higher-paying bonds.
📊 Bond Yields: Your Real Return
Yield tells you how much money you’re REALLY making.
The coupon rate is nice, but yield shows the complete picture—especially if you didn’t pay face value for the bond!
Two Types of Yield You Must Know:
| Yield Type | What It Measures | Best For |
|---|---|---|
| Current Yield | Annual return based on current price | Quick comparison shopping |
| Yield to Maturity | Total return if held until end | Long-term planning |
🔍 Current Yield: The Simple Snapshot
Current yield = What you earn RIGHT NOW compared to what you paid.
The Formula
Current Yield = (Annual Coupon Payment ÷ Current Market Price) × 100
Example:
- Annual Coupon: $50
- You paid: $950 (discount!)
- Current Yield: ($50 ÷ $950) × 100 = 5.26%
🛒 Shopping Comparison
You’re buying two bonds:
| Bond | Coupon | Price You Pay | Current Yield |
|---|---|---|---|
| Bond A | $50 | $1,000 | 5.0% |
| Bond B | $50 | $900 | 5.56% |
Bond B has a higher current yield because you paid less for the same $50!
It’s like buying the same TV on sale—you get more value for your money.
🎯 Yield to Maturity (YTM): The Complete Picture
YTM is the TOTAL return you’ll earn if you hold the bond until it matures.
This is the “big boss” of yield calculations because it includes:
- ✅ All your coupon payments
- ✅ Any profit OR loss from the price difference
- ✅ The time value of money
The Journey Analogy 🚗
- Current Yield = Your speed right now (65 mph)
- YTM = Your average speed for the ENTIRE trip (including stops, traffic, everything)
Example: Discount Bond YTM
You buy a bond for $950 that:
- Pays $50 per year (5% coupon)
- Returns $1,000 at maturity in 3 years
Your total return includes:
- 3 years × $50 = $150 in coupons
- $50 profit when you get back $1,000 (you only paid $950!)
- Total: $200 on a $950 investment
The YTM formula is complex, but just remember:
| If You Pay… | YTM is… | Why? |
|---|---|---|
| Discount ($950) | Higher than coupon rate | You get a bonus at maturity! |
| Par ($1,000) | Equal to coupon rate | No extra gain or loss |
| Premium ($1,050) | Lower than coupon rate | You lose a bit at maturity |
🎬 Putting It All Together
Let’s follow one bond through its journey:
Meet “The Helper Bond” 📜
- Issuer: City of Helperville (wants to build a playground)
- Face Value: $1,000
- Coupon Rate: 5% (pays $50/year)
- Maturity: 5 years
graph TD A["Day 1: Buy at $1,000"] --> B["Year 1: Get $50"] B --> C["Year 2: Get $50"] C --> D["Year 3: Get $50"] D --> E["Year 4: Get $50"] E --> F["Year 5: Get $50 + $1,000 back!"] F --> G["Total Earned: $250 profit!"]
What If Interest Rates Rise to 7%?
After Year 1, interest rates jump. New bonds pay 7%.
Your 5% bond’s market value drops to about $920.
But here’s the secret: If you hold until maturity, you STILL get your $1,000 back!
Bond prices only matter if you sell early.
🧠 Key Takeaways
- Bonds = Loans where YOU are the lender
- Face Value = The promised payback amount
- Market Value = What it’s worth today (changes daily!)
- Coupon Rate = Your locked-in annual interest percentage
- Current Yield = Annual return vs. what you actually paid
- Yield to Maturity = Total return including everything
The Golden Rule of Bonds 🌟
Interest rates ⬆️ = Bond prices ⬇️ Interest rates ⬇️ = Bond prices ⬆️
