Calculate the duration of a 3 year from maturity bond that has a 5.00% annual pay coupon rate and a 2.50% yield. (Use 4 decimal point precision.)
Annual coupon rate = 5%
YTM = 2.5%
Face value of the bond = 1000
Time to maturity = 3 years
Following are the cash flows for this bond:
C1 = 50, C2 = 50, C3 = 50+1000 = 1050
Present Value of these cash flows are:
Present value of C1 = PV(C1) = C1/(1+r)1 = 50/(1+2.5%)1 = 48.780487804878
Present value of C2 = PV(C2) = C2/(1+r)2 = 50/(1+2.5%)2 = 47.5907198096371
Present value of C3 = PV(C3) = C3/(1+r)3 = 1050/(1+2.5%)3 = 975.029381465736
Present value of the bond is the sum of present value of aall future cash flows
Present value of bond = PVBond = PV(C1) + PV(C2) + PV(C3) = 48.780487804878+47.5907198096371+975.029381465736 = 1071.40058908025
Duration of the bond is given by the below formula:
Duration = [(1*48.780487804878)+(2*47.5907198096371)+(3*975.029381465736)]/1071.40058908025 = 3069.05007182136/1071.40058908025 = 2.86452154600363
Answer -> Duration = 2.8645 years
