Yield to Maturity vs Yield to Call: Understanding the Key Differences

Introduction

Yield is one of the most commonly analysed aspects of fixed-income instruments. Among the various measures of yield, two widely used ones are Yield to Maturity (YTM) and Yield to Call (YTC). While both describe potential yield estimates based on today’s market price, they differ in how they interpret cash flows and maturity assumptions.

Understanding what YTM means, how the yield to maturity formula works, and how yield to call applies to callable bonds helps investors interpret fixed-income characteristics more clearly.

This article explains YTM vs YTC, how each measure is calculated, and when each is used in fixed-income analysis.

What Is Yield to Maturity (YTM)?

Yield to Maturity (YTM) represents the estimated yield an investor may earn if:

• the bond is purchased at today’s market price,

• held until maturity, and

• all coupon and principal payments are made as scheduled.

YTM considers the bond’s:

• coupon payments,

• final repayment,

• current market price, and

• remaining time to maturity.

It provides a holistic view of the bond’s yield assuming it remains outstanding until maturity.

Yield to Maturity Meaning & Purpose

The meaning of YTM can be summarised as follows:

• It represents the internal rate of return (IRR) of a bond held until maturity.

• It reflects the discount rate at which the present value of all future cash flows equals the bond’s current price.

• It incorporates both coupon income and capital gain or loss (difference between purchase price and redemption value).

• YTM is a widely used analytical metric because it combines multiple variables into a single estimated yield measure.

Yield to Maturity Formula

The general form of the yield to maturity formula is:

P=∑t=1nCFt(1+y)tP = \sum_{t=1}^{n} \frac{CF_t}{(1+y)^t}P=t=1∑n​(1+y)tCFt​​

Where:

PPP = Current bond price

CFtCF_tCFt​ = Cash flow at time t

yyy = Yield to maturity

nnn = Number of periods

This formula is typically solved using trial-and-error, numerical tools, or a yield to maturity calculator, since algebraic rearrangement is not straightforward.

Example: How YTM Is Estimated

Suppose a bond:

has a face value of ₹1,000, offers an annual coupon of ₹80, trades at ₹950, and matures in 3 years. To estimate YTM:

Discount each year’s cash flow using trial values of y. Adjust the yield until the present value of cash flows approximately equals the current price. Digital tools such as yield calculators can assist in this estimation.

What Is Yield to Call (YTC)?

Some bonds include a call feature, allowing the issuer to redeem the bond before its full maturity date.

Yield to Call (YTC) estimates the yield assuming:

• the bond is purchased at today's price, and

• is called (redeemed early) at the next available call date at the call price.

YTC measures the yield an investor may receive if the bond does not remain outstanding until its final maturity, but instead until its next call event.

Yield to Call Meaning & Purpose

Yield to Call helps investors understand:

• the potential yield when the issuer may redeem early,

• how a callable structure influences yield estimates,

• the relationship between call price, coupon, and market yield.

For bonds with embedded call features, YTC provides an alternative lens for evaluating yield characteristics besides YTM.

Yield to Call Formula

The formula for YTC mirrors the YTM approach but uses call date and call price instead of maturity and face value:

P=∑t=1cCFt(1+y)t+CP(1+y)cP = \sum_{t=1}^{c} \frac{CF_t}{(1+y)^t} + \frac{CP}{(1+y)^c}P=t=1∑c​(1+y)tCFt​​+(1+y)cCP​

Where:

PPP = Current bond price

CFtCF_tCFt​ = Cash flows until the call date

CPCPCP = Call price

ccc = Time (years) until call

yyy = Yield to call

Like YTM, this is generally calculated using numerical tools or a yield to call calculator.

YTM vs YTC: Key Differences

Both YTM and YTC estimate yield using market price and cash flows, but their assumptions differ.

1. Maturity Assumption

• YTM assumes the bond remains outstanding until final maturity.

• YTC assumes the bond is redeemed early at the call date.

2. Cash Flow Horizon

• YTM includes all future coupon payments and final redemption.

• YTC includes only payments until the possible call.

3. Applicable Bonds

• YTM applies to all bonds.

• YTC applies only to callable bonds.

4. Redemption Price

• YTM uses face value.

• YTC uses call price, which may differ from face value.

5. Analytical Purpose

• YTM offers a long-term yield estimate.

• YTC estimates potential yield under an early redemption scenario.

• Understanding these differences helps investors interpret callable bond structures more effectively.

When Investors Refer to YTM and YTC

Investors reference YTM when:

• analysing long-term cash flow expectations,

• evaluating non-callable bonds,

• comparing yield estimates across fixed-income options.

Investors reference YTC when:

• analysing callable bonds,

• assessing yield expectations under early redemption,

• reviewing call price and call schedule information.

Together, YTM and YTC provide a broader understanding of how yield estimates change based on bond structure.

YTM/YTC and Interest Rate Scenarios

Price sensitivity varies when yields change. Although duration and convexity describe sensitivity, YTM and YTC help interpret how yield calculations may differ under:

• varying market price levels,

• changes in interest rate expectations,

• scenarios where a call option is more or less likely to be exercised.

These measures help investors understand yield characteristics in changing market environments.

Using YTM & YTC as Analytical Tools

YTM and YTC are widely used to:

• compare bond structures,

• interpret issuer call schedules,

• analyse pricing relative to prevailing yields,

• study differences between long-term and call-adjusted yield estimates.

• Neither measure predicts performance—both serve as analytical tools to interpret bond price relationships.

Conclusion

Both Yield to Maturity (YTM) and Yield to Call (YTC) are essential concepts for understanding fixed-income yield estimates.

YTM describes the estimated yield assuming the bond is held to maturity, while YTC provides an estimate assuming early redemption at the call date.

By learning the yield to maturity formula, yield to call formula, and how these yields differ, investors gain deeper insight into how bond structures influence yield calculations.
