How to Calculate Yield on a Bond Equivalent Basis

The bond equivalent basis is the non-annual bond rate in annual terms. It can be implicitly calculated through the difference in bond prices. The bond equivalent basis yield then helps investors to adequately compare two different rates. Without a comparable rate, investors are comparing apples and oranges. Instead, they can use a simple calculation to convert the yield rate. Professional investors will automatically convert this rate through computer calculation. However, individual investors may convert the rate manually.

Step 1

Gather the information about your bond investment. The data you need includes the face value, the purchase price and the days until maturity.

Step 2

Input the data into the formula to find the bond equivalent basis. The calculation is face value minus purchase price then divided by purchase price. This number is multiplied by 365 divided by the days until maturity. ((face value - purchase price) / purchase price) x (365 / days until maturity)

Step 3

Complete the calculation by filling in the data and computing. In this example, we will use 97 for purchase price, 110 for face value and 60 days until maturity. ((110 - 97) / 97) x ( 365 / 60) = .81
