First we calculate the price of bond at YTM = 9.40% and with yield changes of +/- 40bps i.e. (0.40%)
Formula used in excel:
Approximate Modified Duration = (V1-V2) / (2*V0*Change in yield)
Approximate Modified Duration = (902.4405 - 855.4616) / (2*878.5386*0.40%)
Approximate Modified Duration = 6.684
