Yield to maturity is the total return expected on a bond if the bond is held up until the expiration of its lifetime.
To solve, the formula is:
Approx. YTM = C + F-P/n divided by F+P/2
Where:
C = Coupon Rate = 7.25%
F = Face Value = $1000
P = Price = $1,125
n = years to maturity = 13
Annuity Payment = 72.50
Solution:
Approx. YTM = 72.50 + (1000-1125/13) divided by (1125+1000/2)
Answer: 5.85%
