How to Calculate Bond Yield: Current Yield, YTM, and Yield to Call Explained
When someone says a bond "yields 5%," they might mean three completely different things. Bond yield is one of the most confusing concepts in investing because there are multiple types — each measuring something different. This guide demystifies all three.
The Three Types of Bond Yield
| Yield Type | What It Measures | Formula Complexity | Most Useful For |
|---|---|---|---|
| Current Yield | Annual income relative to current price | Simple | Quick income comparison |
| Yield to Maturity (YTM) | Total return if held to maturity | Complex | Comparing bonds fairly |
| Yield to Call (YTC) | Total return if called early | Complex | Callable bond analysis |
1. Current Yield
The Formula
Current Yield = (Annual Coupon Payment ÷ Current Market Price) × 100
Example
A bond with:
- Face value: $1,000
- Coupon rate: 5% (pays $50/year)
- Current market price: $950
Current Yield = ($50 ÷ $950) × 100 = 5.26%
Notice: the bond is trading at a discount ($950 vs $1,000 face value), so the current yield (5.26%) is higher than the coupon rate (5%). This makes sense — you're getting the same $50 annual payment for a lower price.
| Bond Price vs Face Value | Current Yield vs Coupon Rate |
|---|---|
| Discount (price < $1,000) | Current yield > coupon rate |
| Par (price = $1,000) | Current yield = coupon rate |
| Premium (price > $1,000) | Current yield < coupon rate |
Limitations
Current yield ignores two important factors:
- Capital gain/loss at maturity — if you bought at $950 and get $1,000 at maturity, that's a $50 gain
- Time value of money — a dollar received today is worth more than a dollar received in 10 years
2. Yield to Maturity (YTM)
YTM is the total annualized return you earn if you hold the bond to maturity, accounting for coupon payments, reinvested interest, and any capital gain or loss.
The Formula
YTM is found by solving:
Price = C/(1+r) + C/(1+r)² + ... + C/(1+r)^n + FV/(1+r)^n
Where:
- C = annual coupon payment
- r = yield to maturity (what we're solving for)
- n = years until maturity
- FV = face value ($1,000)
This equation can't be solved algebraically — it requires iteration or a financial calculator.
Example
Same bond: $1,000 face, 5% coupon, currently $950, 10 years to maturity.
Using our Bond Yield Calculator:
YTM ≈ 5.66%
This is higher than the current yield (5.26%) because YTM includes the $50 capital gain when the bond matures at $1,000.
Comparing Bonds with YTM
YTM is the gold standard for comparing bonds because it accounts for everything:
| Bond | Coupon | Price | Maturity | Current Yield | YTM |
|---|---|---|---|---|---|
| Bond A | 4.0% | $920 | 10 years | 4.35% | 5.02% |
| Bond B | 6.0% | $1,050 | 10 years | 5.71% | 5.44% |
| Bond C | 5.0% | $980 | 5 years | 5.10% | 5.43% |
Looking at current yield alone, Bond B seems best (5.71%). But YTM reveals Bond B is actually the most expensive (5.44%) — its premium price means a capital loss at maturity.
3. Yield to Call (YTC)
Some bonds are callable — the issuer can buy them back before maturity (usually at a small premium over face value). YTC calculates your return assuming the bond is called at the earliest possible date.
The Formula
Same as YTM, but replace the maturity date and face value with the call date and call price:
Price = C/(1+r) + C/(1+r)² + ... + C/(1+r)^n + Call Price/(1+r)^n
Example
A callable bond: $1,000 face, 6% coupon, price $1,040, callable in 5 years at $1,020, matures in 15 years.
| Yield Measure | Value |
|---|---|
| Current Yield | 5.77% |
| YTM (15 years) | 5.65% |
| YTC (5 years) | 5.38% |
If interest rates drop, the issuer will likely call this bond (refinancing at lower rates). In that case, your actual return would be the lower YTC — so always check both.
Rule: When a bond trades at a premium, focus on YTC. When it trades at a discount, focus on YTM.

Yield Curve and What It Tells You
The yield curve plots yields across different maturities:
| Maturity | Typical Yield (Normal Curve) | Inverted Curve |
|---|---|---|
| 3-month T-bill | 4.25% | 5.25% |
| 2-year Treasury | 4.50% | 5.00% |
| 5-year Treasury | 4.75% | 4.50% |
| 10-year Treasury | 5.00% | 4.25% |
| 30-year Treasury | 5.25% | 4.00% |
Normal curve: Longer maturities pay more (compensation for time risk). This is the healthy default.
Inverted curve: Short-term rates exceed long-term rates. Historically, this has preceded recessions about 70% of the time.
Bond Yield vs. Stock Dividend Yield
| Factor | Bond Yield | Stock Dividend Yield |
|---|---|---|
| Principal safety | Returned at maturity (if no default) | No guarantee |
| Income predictability | Fixed schedule | Can be cut or eliminated |
| Growth potential | Limited to par + coupons | Unlimited price appreciation |
| Inflation protection | None (fixed coupons) | Companies can raise dividends |
| Tax treatment | Ordinary income (federal bonds: state-exempt) | Qualified dividends (lower rate) |
Bonds provide certainty; stocks provide growth. A balanced portfolio uses both.
Factors That Affect Bond Yields
| Factor | Effect on Yield |
|---|---|
| Interest rate increases | Yield rises (prices fall) |
| Credit rating downgrade | Yield rises (risk premium) |
| Approaching maturity | Yield converges toward coupon rate |
| Inflation expectations | Higher inflation → higher yields |
| Economic uncertainty | Flight to safety lowers Treasury yields |
Practical Application: Building a Bond Allocation
For Safety and Income (Retirees):
Focus on high-quality bonds (Treasury, investment-grade corporate) with a ladder of maturities. Compare using YTM.
For Total Return (Growth Investors):
Consider bond funds that actively manage duration and credit quality. Focus on the fund's SEC yield (standardized 30-day yield).
For Tax Efficiency:
Municipal bonds ("munis") pay interest exempt from federal taxes. Their tax-equivalent yield = Muni Yield ÷ (1 - Tax Bracket):
A 3.5% muni yield for someone in the 32% bracket: 3.5% ÷ 0.68 = 5.15% tax-equivalent yield

Understanding bond yield isn't just academic — it's the difference between overpaying for income and building a portfolio that reliably delivers your target return.
