Answer: Macaulay Duration = 2.6908154485 = 2.69

Explanation:

Macaulay Duration = Sum of Cash flows Present Value / current bond price

Cash flows: year 1 = $12

Cash flows: year 2 = 12

Cash flows: year 3 = 100 + 12 = 112

Sum of Cash Flow PV = (1*12: (1.118) ^1) + (2*12: (1.118) ^2) + (3*112: (1.118) ^3)

Sum of Cash Flow PV = 270.37857712

Current Bond Price or Value = Face Value / (1+r) ^n + PV of Annuity

Current Bond Price or Value = 1000 / (1.118) ^3 + (30 * (1 - (1+0.118) ^-3) / 0.118

Current Bond Price or Value = 100.48202201

Macaulay Duration = 270.37857712 : 100.48202201

Macaulay Duration = 2.6908154485 = 2.69
