A T-bond with semi-annual coupons has a coupon rate of 7%, face value of $1,000, and 2 years to maturity. If its yield to maturity is 5%, what is its Macaulay Duration? Answer in years, rounded to three decimal places.
K = Nx2 |
Bond Price =∑ [( Coupon)/(1 + YTM/2)^k] + Par value/(1 + YTM/2)^Nx2 |
k=1 |
K =2x2 |
Bond Price =∑ [(7*1000/200)/(1 + 5/200)^k] + 1000/(1 + 5/200)^2x2 |
k=1 |
Bond Price = 1037.62 |
Period | Cash Flow | Discounting factor | PV Cash Flow | Duration Calc |
0 | ($1,037.62) | =(1+YTM/number of coupon payments in the year)^period | =cashflow/discounting factor | =PV cashflow*period |
1 | 35.00 | 1.03 | 34.15 | 34.15 |
2 | 35.00 | 1.05 | 33.31 | 66.63 |
3 | 35.00 | 1.08 | 32.50 | 97.50 |
4 | 1,035.00 | 1.10 | 937.66 | 3,750.64 |
Total | 3,948.91 |
Macaulay duration =(∑ Duration calc)/(bond price*number of coupon per year) |
=3948.91/(1037.62*2) |
=1.903 |
