Calculate YTM – Assume a bond will mature in 20
years.
A. Calculate the YTM for a bond with a price of $874 and annual
payment of $70.
B. Calculate the price at the end of year 10. Calculate the price
at the end of year 19. Explain the results.
No excel! Must use formulas.
20 year maturity bond
No of periods = 20 years
Bond Price = Coupon / (1 + YTM)period + Face value / (1 + YTM)period
$874 = $70 / (1 + YTM)1 + $70 / (1 + YTM)2 + ...+ $70 / (1 + YTM)20 + $1000 / (1 + YTM)20
Using Texas Instruments BA 2 Plus Calculator
SET N = 20, FV = 1000, PMT = 70, PV = -874
CPT I/Y = 8.31
YTM = I/Y = 8.31%
Price at the end of year 10
Bond Price = Coupon / (1 + YTM)period + Face value / (1 + YTM)period
Bond Price = $70 / (1 + 8.31%)1 + $70 / (1 + 8.31%)2 + ...+ $70 / (1 + 8.31%)10 + $1000 / (1 + 8.31%)10
Using PVIFA = (1 - (1 + Interest rate)- no of periods / interest rate to value coupons
Bond Price = $70 * (1 - (1 + 8.31%)-10) / (8.31%) + $1000 / (1 + 8.31%)10
Bond Price = $463.21 + $450.11
Bond Price = $913.31
Price at the end of year 19
Bond Price = Coupon / (1 + YTM)period + Face value / (1 + YTM)period
Bond Price = $70 / (1 + 8.31%)1 + $1000 / (1 + 8.31%)1
Bond Price = $64.63 + $923.28
Bond Price = $987.91
The bond is trading at a discount as the bond nears maturity the price of the bond moves closer to the Par value. This explains the difference in the prices at year 10 & year 19. At year 19 the price is closer to the Par value. At year 10 th price is far away from the Par value.
