Bond Calculation
u Terms in the formulas
PRC
: price per $100 of face value
RDV : redemption price per $100 of face value
CPN : coupon rate (%)
YLD : annual yield (%)
M : number of coupon payments per year
(1 = Annual, 2 = Semi-annual)
N : number of coupon payments until maturity ( n is
used when “Term” is specified for “Bond Interval”.)
INT : accrued interest
CST : price including interest
A : accrued days
D : number of days in coupon period where settlement occurs
B : number of days from purchase date until next coupon payment date = D – A
D
