npv

npv(stream, discountRate, initialValue, factor, timeStep) is the system dynamics function that returns the net present value of stream computed using discountRate. The initial value is determined by initialValue (usually 0) and the value is reported after multiplying by factor (usually 1). 

Example: 


npv can be called in formulas of system dynamics variables.

Units: 

stream -> units
discountRate -> 1/time
initialValue -> units*time
factor
-> dimensionless
timeStep -> time

npv() -> units*time
