Par value:Par value:Par value:Par value:

Par value:

Enter the par value of the bond (only numeric characters 0-9 and a decimal point, no dollar sign or commas). Par value is also referred to as the face value.

Coup rate:Coupon rate:Coupon rate:Coupon rate:

Coupon rate:

Enter the coupon rate of the bond (only numeric characters 0-9 and a decimal point, no percent sign). The coupon rate is the annual interest the bond pays. If a bond with a par value of $1,000 is paying you $80 per year, then the coupon rate would be 8% (80 ÷ 1000 = .08, or 8%).

Compound:Compounding:Rate compounding interval:Coupon rate compounding interval:

Coupon rate compounding interval

Select the compounding frequency of the coupon rate. Typically, the shorter the compounding interval, the more interest you will earn with all other factors remaining the same. While the effects of compounding are fairly insignificant for small investments, the effects can be very significant when investing a large sum of money.

Mkt rate:Market rate:Current market rate:Current market rate of similar bonds:

Current market rate of similar bonds:

Enter the current market rate that a similar bond is selling for (only numeric characters 0-9 and a decimal point, no percent sign). If the current market rate is below the coupon rate, then the bond should be trading at a premium (price greater than the par value). Conversely, if the current market rate is above the coupon rate, then the bond should be selling at a discount (price less than par value).

Yrs to mat:Yrs to maturity:Years to maturity:Years to maturity:

Years to maturity:

Enter the number of years remaining before the bond reaches its maturity date (whole numbers only). The maturity of a bond is the year the par or face value of the bond is returned to the bond holder.

Bond value:Bond value:Bond value:Bond value:

Bond value:

Given the face value, coupon rate, coupon compounding interval, years to maturity, and the current market rate, this is the price your bond would be trading at. In other words, this should be the price a buyer would be willing to pay to purchase your bond.
