Forward Rate
[(1+YTM2)^2/1+YTM]-1
Price of bond
FV / YTM as a percentage^year
Calculating the YTM for the same bond next year
percentage change of price of bond between next year bond price and this year bond price - old - new /new
Calculating FV (if you can’t do in calc usually macul duration)
Sum PV x discount rate^year of duration
Predicted price change
(-duration/1+y) x chnage in y x po (initial price)
Percentage error calculation
New - old / old
Rate of return (bond)
end year price + coupon + beginning / beginning
Predicted price change convexity
(- duration / 1 + y) + (1/y x C x y) x Po
Modified duration
Macaulay duration / 1 + YTM
