Abstract: A system for facilitating simulations and modelling of market sales volume is provided including a server, an input device, at least one web pages, and software for projecting penetration of merchandise at a predetermined number of weeks, W, since a launch of a product, based on weekly data of initial purchases from a launch of a product. The software can also be operable for generating a curve from weekly sales data. The software can also be operable for retrieving a component of the curve (B) representing a degree of belly of the curve, retrieving a component from the curve representing a slope term (S) and performing a calculation to produce a predicted or continued value for components of market sales volume using the B component and the slope component (S) in a formula, wherein the formula is: Predicted=Exp(S)×W(B).
