The term yield-to-maturity, or YTM, is closely associated with bonds. As a result, YTM is an important term for debt mutual funds. The annual return is expressed as YTM. It tells us what the overall return on a bond would be if the investor keeps it until maturity. A debt fund’s underlying assets are a variety of government and corporate bonds that the fund manager prefers to hold in the portfolio.

Meaning of Yield to Maturity

Yield to maturity is the annualized rate of return that an investor can expect if they keep a bond before it matures. A fund manager keeping bonds in a mutual fund portfolio is in the same boat. YTM assumes that the lender has re-invested all of the bond’s interest payments before the bond matures. It can also take into account the reinvestment of principal at maturity.

A debt mutual fund scheme’s YTM

The estimated return an investor may expect if ALL of the bonds and other securities in a debt scheme are kept until maturity (YTM minus expense). It’s also known as the weighted average of all the underlying securities’ yields divided by the holding’s proportion. Since debt schemes are actively managed, the fund manager can adjust the fund’s portfolio in response to market conditions, the YTM of a debt scheme may not be constant.

As a result, YTM minus expense can be a rough measure of how much return an investor can expect if all securities are held until maturity, but returns can vary due to interest rates and portfolio adjustments. It’s possible that the debt mutual fund scheme you’re investing in is taking higher risks, which is why your debt scheme has a high YTM. The bond’s market price and yield are inversely related. If the stock price falls, the YTM will rise.

When choosing a scheme, investors should consider the YTM in conjunction with the underlying portfolio since a high YTM does not always imply a high return or a good match in your portfolio.

 The formula of Yield to Maturity (YTM) 

The YTM formula for a single Bond is:

Yield to Maturity = [Annual Interest + {(FV-Price)/Maturity}] / [(FV+Price)/2]

In the above formula,

  • Annual Interest = Annual Interest Payout by the Bond
  • FV = Face Value of the Bond
  • Price = Current Market Price of the Bond
  • Maturity = Time to Maturity i.e. number of years till Maturity of the Bond

Yield to Maturity’s Importance

The most important aspect of yield to maturity is that it allows investors to compare various securities and the returns they may expect from each. It is crucial in deciding which securities to include in their portfolios Also, it enables investors to recognize how shifts in market dynamics impact their portfolio, because when the price of shares falls, the yield increases, and vice versa.

What are YTMs and how do they work?

The present value of all potential cash flows will be determined by the price at which the bond can be purchased on the market.

Bonds, on the other hand, are marketable securities, and their values fluctuate in response to the economy’s changing interest rates.

Here’s the rub: there’s a catch. The bond’s coupon rate is set until it matures. The price and yield are the only things that change. So, if a bond has a face value of Rs 2,000 and a 5% coupon rate. The coupon rate would then remain constant until maturity. The price may rise or fall. When market interest rates increase faster than the coupon rate paid on bonds, the bond becomes less appealing. The bond’s price falls as a result of this. When interest rates decline, the reverse occurs. The bond becomes more appealing as the coupon rates rise, driving the bond price higher.

When looking at the yield to maturity model, you’ll notice that it assumes that all coupon payments are reinvested in the bond, resulting in the present value of cash flows equaling the bond’s current market price. The YTM of the bond is the rate at which cash flows are assumed to be invested.

Yield to Maturity’s (YTM) Uses

Yield to maturity is a valuable tool for determining whether or not purchasing a bond is a safe investment. A required yield will be determined by an investor (the return on a bond that will make the bond worthwhile). When an investor knows the YTM of a bond they’re considering buying, they can compare it to the appropriate yield to see if the bond is a good investment.

Since YTM is expressed as an annual rate regardless of the bond’s term to maturity, it can be used to equate bonds of different maturities and coupons. The yield to maturity (YTM) of a bond is important since it shows the return if the bond is held to maturity. Bonds, Certificates of Deposits, and Commercial paper are common underlying holdings in debt funds. YTM is calculated by fund managers to provide a forecast of cash flow rather than returns.

Varieties of Yield to Maturity (YTM)

There are a few common variations of yield to maturity that account for bonds with embedded options.

  • The yield to call (YTC) is based on the assumption that the bond will be called. That is, the issuer repurchases a bond before it matures, resulting in a shorter cash flow duration. The YTC is determined based on the premise that the bond will be called as soon as possible and financially feasible.
  • Yield to put (YTP) is similar to yield to call (YTC), except that a put bondholder can opt to sell the bond back to the issuer at a fixed price depending on the bond’s terms. The YTP is determined assuming that the bond will be returned to the issuer as soon as possible and financially feasible.
  • If a bond has several choices, the yield to worst (YTW) equation is used. If an investor were reviewing a bond that had both calls and put clauses, they would measure the YTW using the option terms that yielded the lowest yield.

What is the difference between the YTM and the coupon rate of a bond?

The key distinction between a bond’s YTM and its coupon rate is that the coupon rate is constant, while the YTM varies with time. The coupon rate is contractually fixed, while the YTM fluctuates depending on the bond’s price as well as interest rates available elsewhere in the market. If the YTM is greater than the coupon rate, the bond is being sold at a lower price than its par value. If the YTM is lower than the coupon rate, however, the bond is being sold at a discount.

The yield based on the asset class

Based on the asset class, there are two types of yields.

  • When it comes to stocks,

In the case of securities, yield refers to the return on the dividend received by the stockholder. It excludes the benefit from the sale of the shares. The general formula for stock yield is as follows:

In the case of stocks, the yield is calculated as (price increase + dividend paid)/price.

  • When it comes to shares,

The interest yield on a bond is the return on investment. The coupon rate is another name for interest. As a result, bond yields are determined by the coupon rate. It’s known as natural yield in the case of bonds. This is the annual rate of return on fixed-income investments.

Normal yield = Yearly interest earned/ Bond face value

What is the current yield?

The annual cash flows of investment are divided by the security’s current market price to calculate the current yield. It depicts the current rate of return that an investor will receive if they bought and kept the stock for a year. The current yield does not reflect the real yield that an investor would receive if the investment were held to maturity. The annual return on investment, on the other hand, is what it is.

Current yield = Yearly Cash Flows/ Current price.

Year-end cash flows = Price rise in the security plus the dividend

The expression “current yield” is most often used in the context of bonds. This is due to the fact that the bonds are sold at a premium or discount to par value. When investors purchase a bond, they may want to measure the possible return on their investment. In these situations, the current yield is usually used.

Present yield, on the other hand, may be applied to stocks or equities. Divide the dividend by the current share price to get the current yield, thats the calculation.

Terms linked to YTM

Following are few essential terms in the yield to maturity formula

Face value/ Par value

The bond’s face value, also known as the par value, is the amount it will be worth when it matures. In other words, this is the amount paid to the bondholder when the bond reaches maturity.

Present value/ Market value

The current selling price is the bond’s present value or market value. Bond rates are subject to interest rate increases, which cause them to fluctuate. The relationship between price and yield is inverse.

Coupon rate

The coupon rate is the amount of interest paid by the bond issuer to the bondholder. The coupon rate is based on the face value of the bond rather than the market value.

Interest rate

A bond’s interest rate and coupon rate are not the same. Let’s look at an example to help you understand. Mr. Ananth purchases a bond with a face value of INR 1,000 and a coupon rate of 10%. Mr. Ananth receives INR 100 (10 percent of INR 1,000) in annual coupon payments for his savings. For him, the effective interest rate is 10%.

Ms. Sushma, on the other hand, purchases a bond for INR 2,000. (at a higher price to its face value). The bond has a face value of INR 1,000 and a ten percent coupon rate. Ms. Sushma also receives a yearly payment of INR 100 (10% of INR 1,000) in the form of annual coupon payments. However, since she purchased the bond for INR 2,000, the interest rate on her investment is 5% (INR 100 of INR 2,000). Similarly, if an investor purchased a bond for less than its face value, the interest rate would be greater than the coupon rate.

Discount and Premium

Bonds trade both at discount or premium. When,

Market value is equal to Face value, the bond is trading at par

Face value is less than Market value, the bond is trading at a premium

Face value is greater than Market value, the bond is trading at a discount

Time to maturity

Maturity refers to the time or period when a bond’s principal and interest are repaid. A 10-year government bond, for example, would mature in 10 years. At that point, the bondholder gets the principal sum as well as interest. Maturity is most often referred to as “time to maturity.” This graph represents the period of time before the bond matures.


YTM may be applied to know whether a bond is a safe investment or not. It aids in determining whether or not a bond is worth investing in. You may equate a bond’s YTM to that of other bonds to determine which has a better path to maturity. YTM may also be utilized to contrast bonds of various maturities for a like-to-like evaluation. The most important thing to remember is that YTM provides you with planned returns. Even though bonds are less risky than stocks, the stone can’t take anything in the world of investments. Make an educated decision while still considering other factors.
