K = N

Bond Price =? [( Coupon)/(1 + YTM)^k] + Par value/(1 + YTM)^N

k=1

K =25

Bond Price =? [(5*1000/100)/(1 + 6/100)^k] + 1000/(1 + 6/100)^25

k=1

Bond Price = 872.17

Period	Cash Flow	Discounting factor	PV Cash Flow	Duration Calc	Convexity Calc
0	($872.17)	=(1+YTM/number of coupon payments in the year)^period	=cashflow/discounting factor	=PV cashflow*period	=duration calc*(1+period)/(1+YTM/N)^2

Convexity =(? convexity calc)/(bond price*number of coupon per year^2)

=224912.23/(872.17*1^2)

=257.88 = 259.07
