But why Excel for Monte Carlo simulation?
Well, unlike others, Excel is a versatile tool that allows you to easily perform complex calculations.
Widely accessible, user-friendly, and built with many statistical functions, Excel is the ideal choice for Monte Carlo simulations. Its robust data visualization tools not only help you to present your findings clearly, but also instill confidence in your ability to communicate effectively.
The Monte Carlo simulation is based on statistics and statistical principles. These are the foundations of data analysis, results interpretation, and decision-making for this method.
To truly understand and use Monte Carlo simulation, you have to be aware of key statistical measures used to describe data, such as:
- Mean: The average value
- Median: The middle value in a sorted (ascending or descending) data set
- Standard Deviation: A measure of how spread out the data is from the mean (average) value
- Variance: The square of the standard deviation that measures the spread of data points
- Normal Distribution: A bell-shaped curve representing the probability of different probabilities occurring within a certain range
- Skewness: The measure of asymmetry in a statistical distribution
Core statistical concepts (principles) are also important to know. For instance, a higher standard deviation or variation value means a wider range of data. Conversely, lower values indicate that the data points are closely clustered around the mean.
Here’s another core statistical concept used in the Monte Carlo simulation.
In normal distribution or the bell curve, the highest point—on the symmetrical bell-shaped curve—represents the mean or the most likely outcome.
Similarly, measures like skewness and median accurately model and interpret simulated data, accounting for potential biases and uncertainties.
As you know by now, statistics is at the heart of the Monte Carlo simulation, providing insight into potential outcomes and associated probabilities. Such information is invaluable for decision-making as it deeply assesses risks, uncertainties, and potential scenarios.

The Monte Carlo simulation method is an essential, tried-and-tested risk assessment framework.
Here’s a detailed guide to performing the simulation in Excel, using a dice-rolling example to illustrate the process.
Dice rolling event
Step 1: Define the problem: Let’s use an example of rolling two dice to understand the Monte Carlo simulation process. You want to determine the probability of getting different scores when two dice are rolled simultaneously. Each die has numbers from 1 to 6, so the sum of numbers (total score) on the faces can range from 2 (1+1) to 12 (6+6).
Range of outcomes
Step 2: Determine the range of possible outcomes: The possible sums (total scores) when rolling two dice are integers between 2 and 12. Each sum has a different likelihood because different combinations can produce it. For instance, there’s only one way to get a sum of 2 (1+1), but multiple ways to get a sum of 7 (e.g., 1+6, 2+5, 3+4, etc.).
Number of dice rolls
Step 3: Decide the number of simulations: You should perform many simulations to get a reliable result. Let’s decide to simulate 10,000 rolls of the two dice. The more simulations you do, the more accurate your estimated probabilities will be.
Simulation
Step 4: Set up the spreadsheet for simulation: You can use random number generation functions on an Excel sheet to simulate dice rolls. To generate random numbers or random values, follow these steps:
Generate random numbers
- In cell A2, enter =RANDBETWEEN(1, 6) to simulate the first die roll
- In cell B2, enter =RANDBETWEEN(1, 6) to simulate the second die roll
Calculate the sum
- In cell C2, enter =A2 + B2 to calculate the sum (total score) of the two dice
Extend the simulation
- Copy the formulas in A2, B2, and C2 down to row 10001 to simulate 10,000 dice rolls
Probability
Step 5: Analyze the simulation results to calculate the probability of each outcome (total score). You can do this by using the COUNTIF function.
- Create a frequency distribution list
- In column E, starting from cell E2, list all possible sums of the outcome of two die rolls from 2 to 12
- In column F, starting from cell F2, use the COUNTIF function to count how many times each sum occurs. For example, in cell F2, enter =COUNTIF(C$2:C$10001, E2) and copy this formula down to F13
- Calculate probabilities
- In column G, convert the counts to probabilities by dividing each count by the total number of simulations (10,000). For example, in cell G2, enter =F2 / 10000 and copy this formula down to G12
- You can now name the column heads if you want to
Conclusions
Step 6: Draw conclusions from the results: Analyze the results to understand the likelihood of different outcomes. The values in column G will give you the empirical probabilities of each possible sum based on your simulation.
By comparing these probabilities with the theoretical probabilities, you can validate the accuracy of your simulation. This helps you understand the distribution of outcomes and make informed predictions.

Summarize this article for me pleaseAdvantages and Limitations of Monte Carlo Simulation in Excel
Monte Carlo simulations in MS Excel offer a simple way to model complex statistical distributions, making it a go-to tool for many analysts.
One of the biggest advantages is accessibility. MS Excel is readily available. Also, it’s surprisingly beginner and user-friendly, so you don’t need to be a hardcore data scientist to run simulations.
And if that’s not enough, Excel’s built-in functions and formulas allow you to create sophisticated models that can handle a wide range of scenarios, providing valuable insights into probability distributions and outcomes.
Another significant benefit is scalability. Excel can manage large datasets and numerous simulations with relative ease. For most business applications, Excel’s data-handling capacity is more than enough. You can run countless simulations and still get relevant insights for meaningful decision-making.
Despite excellent advantages, Excel isn’t bulletproof.
One major drawback is the lack of parallel processing capabilities.
Excel can slow down when running extensive simulations because it processes tasks sequentially rather than simultaneously—a bottleneck for time-sensitive analyses.
Also, Excel’s flexibility diminishes as models become more complex. Excel might not offer the required support or efficiency for advanced techniques and highly intricate models.
Other software solutions such as synthetic data generation tools and cloud computing models often surpass Excel in these areas. They provide features like parallel processing and better support for complex models.
Cloud-based tools, in particular, offer scalability far exceeding what Excel can handle, allowing for faster and more efficient simulations.
These Excel alternatives also include advanced statistical techniques and machine learning algorithms, offering a broader range of analytical capabilities.
