Randomness between results will decrease and become meaningful with enough number of runs. With each run of the simulation, a new random variable is generated and used as an input. These random variables can be used as is, or can be used to generate inputs through additional calculations. A stochastic approach is based on collecting random variables.

A stochastic approach, on the other hand, will provide more reliable results. We recommend avoiding the traditional deterministic ways that rely on some fundamental assumptions. If there was a perfect way, forecasting would be a far easier analysis than it actually is. There are various ways to determine the inputs and, unfortunately, none of them are perfect. Without correct inputs, a model can’t generate the correct results. So, the next step is forecasting how many items will be sold.ĭetermining the inputs is just as important as building the calculation model. We know the cost of a single unit, but number of units to be sold and the profit are the two unknowns in this equation. = Units_Sold * ( Sell_Price - Unit_Cost ) Typically, profit is the number of goods sold times the cost of one unit, minus any costs. Companies want to know how many units of products they sold and calculate how much profit it will generate for the next year. Let’s take a profit calculator as an example. All that matters is the model's ability to mimic the real-time process that it’s used to solve.

A simulation in Excel must be built around a model, and that is defined by a system of formulas and mathematical operations.
