Find the yield to maturity on a semi-annual coupon bond with a face value of \$1000, a
10% coupon rate, and 15 years remaining until maturity given that the bond price is \$862.35.

### Calculation of YTM by using PRM allowed calculator-TI -30XS

We can use approximation method :-
semi - annual YTM = [F-P/N]+C/ F+P/2
= [1000-862.35/15*2(semi annual)] + 50(coupon) /(1000+862.35)/2
= 54.58/931.17 = 5.86%

YTM = 2* semi - annual YTM = 2*5.86% = 11.72%

i got it. the way you have written formula is quite confusing. it should have been written as :
(((F-P)/N)+C)/ (F+P)/2
