Return on investment is one of the key drivers for your investment decision. In the case of bond investment, bond yield represents your return on investment. It is the percentage return on a bond investment and is represented as the ratio of the annual coupon payments to the bond’s current market price. The higher the bond yield, the better the return on investment. But how can you calculate bond yield? Is there a bond yield calculator available that automates our return calculation and shows accurate results? Let’s find out!

What is a bond yield?

Before understanding bond yield calculation, it is important to understand what is bond yield. As stated earlier, bond yield is the return on the investment you made in bonds which and is denominated in percentage. It indicates the returns you can earn as per the prevailing bond price. The higher the bond yield, the better the returns. This is what makes it a key driver in bond investing decisions.

How to calculate bond yield online?

Calculating bond yield is simple. It shows the ratio of how much interest you earned as compared to the current market price of the bond. This indicates how much returns bond yields today. For calculating bond yield, the following two pieces of information are required:

Coupon rate:

This is the rate at which the bond pays interest to the investor. Suppose a bond is priced at Rs. 1000 with a coupon rate of 8% per annum. Thus, the bond will pay an interest of Rs. 80 annually to the investor.

The market price of the bond:

This is the current market price at which the bond is trading today.

Following is the bond yield formula to calculate bond yield:

Bond Yield = Coupon amount / Current market price of the bond * 100

To calculate the bond yield, divide the bond’s annual interest payment by the bond’s current market price. For example, let’s say you have invested Rs. 1,000 in a bond with a 8% coupon rate that pays interest annually. The annual interest payment would be Rs. 80 (8% of Rs. 1,000). The bond’s current market price is Rs. 950. So, the bond yield today should be calculated as follows:

Bond Yield = Coupon amount / Current market price of the bond * 100

= Rs. 80 / Rs. 950 * 100

= 8.42%

This is how a yield calculator works.

Generally speaking, the higher the yield to maturity YTM, the better return you can expect on your investment. However, it’s important to remember that yields can fluctuate over time due to change in the current market price of the bond. So, monitor your bonds closely to ensure they are still performing as expected.

What is Yield to Maturity?

Yield to maturity YTM is another significant parameter to measure the bond’s performance. While the bond yield measures the annual return that the bond has provided, yield to maturity measures the annual returns provided by the bond over the total investment tenure.

How to Calculate YTM?

Here’s how to calculate yield to maturity using the YTM formula:

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


Annual interest = Interest paid annually by the bond

Face Value = Face value of the bond

Price = Current market price of the bond

Maturity = Number of years till maturity

Thus, yield to investment considers the overall returns over the life of the bond. Let’s understand how to calculate YTM with a practical example:

Continuing the above example, suppose the life of the bond is 5 years. Following is the complete data for the bond:

Annual interest = Rs. 80

Face value = Rs. 1000

Current Price = Rs. 950

Maturity = 5 years

Therefore, we can calculate the YTM of this bond using the following YTM formula:

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

= [Rs. 80 + {(1000-950)/5}] / [(1000+950)/2] * 100

= 9.23% per annum

That means, the bond will yield returns at the rate of 9.23% annually till its maturity.

Of course, calculating yield is just one part of making intelligent investment decisions. It would be best to consider risk tolerance and objectives before putting your money into a security.
