What is the current yield of a annual coupon bond with a 6% coupon, four years until maturity, and a price of $750?

What you probably really want is the Yield To Maturity (YTM). Assume the bond returns a $1000 face value after 4 years. That is what face value means. The coupon rate is the annual fraction of THAT value paid out.

With annual interest payments, the YTM is 14.7%. Most bonds make an interest payment semiannually. That won't change the YTM much.

There are online Java tools and formulas for computing YTM.

To calculate the current yield of an annual coupon bond, you need to divide the annual coupon payment by the bond's current market price.

Step 1: Calculate the annual coupon payment.
The annual coupon payment is given as 6% of the face value of the bond. Since the face value is not provided, we'll assume it to be $1,000.

Annual coupon payment = 6% * $1,000 = $60.

Step 2: Calculate the current yield.
The current yield is the annual coupon payment divided by the bond's current market price.

Current yield = Annual coupon payment / Current market price

Since the market price of the bond is given as $750, the current yield can be calculated as:

Current yield = $60 / $750 = 0.08 or 8%.

Therefore, the current yield of the bond is 8%.

To find the current yield of a bond, you need to divide the annual coupon payment by the current market price and express it as a percentage. In this case, the annual coupon payment is 6% of the face value of the bond (also known as the par value).

Step 1: Calculate the annual coupon payment.
Since the bond has a 6% coupon rate and the par value is not provided, we'll assume it is $1000 (a common convention). Therefore, the annual coupon payment is $1000 * 0.06 = $60.

Step 2: Calculate the current yield.
The current yield is found by dividing the annual coupon payment by the current market price and converting it into a percentage.
Therefore, the current yield is ($60 / $750) * 100% = 8%.

So, the current yield of this annual coupon bond is 8%.
