However, if we apply the same logic to the first example, we can see how we can funnel the random numbers through a broader financial model. Note that the RAND functions recalculate as a final step after the data table updates, so the input random number in the left column doesn’t relate to the output in the right column. In this simple example, the data table is not doing much using multiple RAND() functions and calculating the resulting die roll.
If we have a random number, we can feed that into a data table to generate results. How is this relevant for running simulations? Well, consider what the overall process is: generating a random input based on a probability distribution, and calculating a result. A data table answers a relatively simple question: “what-if” a target cell had a value X, instead of its current value? If you’re evaluating a business that sells widgets at a price of $10 each, you could quickly assess the profitability at $8 each, or $12 each, or any number of different prices. Let me (re)introduce you to the humble data table.įor those who haven’t used data tables in the past, and are looking for a more in-depth view of how they work, check out Mark Horowitz’s fairly comprehensive write-up in the October 2015 newsletter.
USING VBA IN EXCEL 2016 FOR MAC
What if I can show you a simulation tool that’s built into Excel, is easily scalable and can be added to your existing financial models with minimal effort, without the use of VBA or any sort of macros? The latter point is particularly important-there are many issues with VBA compatibility floatingĪround right now as Excel for Mac reintroduces VBA, and as code needs to be updated for 64-bit and newer versions of Excel. But in most cases, when you want to do some “proper” simulation analysis (think 10,000+ runs based on an input probability distribution), you will usually find an add-in or macro, or even look to a completely different modelling tool.

Usually, Excel models tend to be deterministic black boxes based on a series of assumptions (inputs) and a set of rules (calculations) that result in a fixed outcome (outputs). Excel is a really useful tool for forecasting.
