How to Perform Monte Carlo Simulation in Excel: Risk and Profitability Analysis Guide
In this Excel tutorial you will learn how to perform Monte Carlo simulation in Excel to evaluate risk and forecast outcomes. By using Monte Carlo simulation in Excel, you’ll discover how to model uncertainty in financial models, project management, and forecasting with realistic probability-based scenarios.
Monte Carlo calculations
Let’s move on with calculations.
To calculate revenue I used =(400+RAND()*100)*215 formula:
- remember that number of clients is 400-500
- 400+RAND()*100 will generate random number between 400 – 500
- unit price is 215 and I need to multiply random number of clients in range between 400 and 500 to get total sales
Apply formula to the entire column.
Next, calculate the costs. Simuilarly formula is =(80000+RAND()*30000) to generate random number in range 80,000 – 110,000.
To calculate financial results you just need to know how to subtract in Excel. The formula is =B2-C2.
For the next Profit/Loss column we need to know if it is true or not. Let’s agree that for profit we will see 1 and 0 will be for loss. IF Excel function will do the job!
The formula is =IF(D2>0,1,0)
Now, we are able to calculate the average of expected profit using the Monte Carlo simulation in Excel. The AVERAGE function in Excel simplifies probability calculations and financial analysis, allowing you to evaluate risk and expected outcomes.
The formula is =AVERAGE($D$2:$D$10001)
To calculate probability it is enough to sum column E. Excel Sum function will do the job.
The formula is =SUM($E$2:$E$10001)/10000
Hit F9 keyboard key several times. Please notice that the numbers change slightly. The more rows the smaller the changes will be.
Monte Carlo simulation is finished. Now, based on the number you can decide if it is worth to take the risk and introduce the product into the market. The simulation provides insights into the expected profit and the probability of making a profit.
Excel did the job, now it is on you to take a call.
