can we use duration calculation to do this problem? |

N:30,I/Y:5,PMT:4,FV100 CPT:PV=84,6275 N:30,I/Y:4.5,PMT:4,FV:100 CPT:PV=91,8556 91,8556/84,6275-1=8,54% |

understand the concept with the financial calculator, but since we `re dealing with bonds, why we don`t take FV=1000 ? |

1. Nonlinear curve 2. N=30, I=5, PMT=4, FV=100 => -PV (sto1) then I=4.5 => -PV (sto2) rcl1/rcl2-1=8.54% |

i am calculating this formula on my financial calculator, why am I not getting the right answer. |

seemor: Enter into your Calculator (presumably HP 12c): "PMT": 40 "n": 30 "i": 4.5 "FV": 1000 => Press "PV" result equals 918.556 "PMT": 40 "n": 30 "i": 5 "FV" : 1000 => Press "PV" result equals : 846.275 Take Relation: 918/846 -1 = 8.54% |

remember to clear data each time, otherwise, you may get wrong answer |

Wondering if we can use 'duration' concept here? |

Check if your calculator is not in a BGN mode |
