If

P_(0)

is the initial price of the security,

P_(1)

is the price after you hold it for a year, and

x

represents a direct payment, an asset's rate of return is equal to:\ rate of return

=(P_(1)-P_(0))

\ rate of return

=(P_(1)-P_(0))+x

\ rate of return

=(P_(1)-P_(0))/(P_(0))+xP_(0)

\ rate of return

=(P_(1)-P_(0))/(P_(0))+x

If P0 is the initial price of the security, P1 is the price after you hold it for a year, and X represents a direct payment, an asset's rate of return is equal to: rate of return =(P1P0) rate of return =(P1P0)+X rate of return =(P1P0)/P0+XP0 rate of return =(P1P0)/P0+X
