Discounted Cash Flow (DCF) and Internal Rate of Return (IRR) models are two important tools used by finance professionals and investors to evaluate investment opportunities. DCF looks at the estimated future cash flows of an investment, discounted to the present value, while IRR is the rate of return needed to make a given investment worthwhile. While both of these models can be used to efficiently evaluate potential investments, Excel is often used to implement them.

Adopting these models in Excel has many advantages. For starters, Excel is easily accessible and can serve as a powerful solution for developing sophisticated financial models. When combined with powerful 3rd-party add-ins and functions, Excel can easily be tailored to perform the type of analysis necessary for advanced DCF and IRR analysis. Below are some of the key benefits of using Excel to build these models.

Overview of Discounted Cash Flow (DCF) Model

Discounted Cash Flow (DCF) Model is a valuation methodology used for pricing of a company's stock or other investments. It provides investors with a system for assessing the intrinsic value of a project or asset. The DCF model consumes the projected, future cash flows from an investment in order to determine its current market value, which helps investors decide if to invest in the project or not.

Overview of the Valuation Model

The DCF Model is based on the premise that the value of an investment should be equal to its expected returns. The model can be used in the case of a business, equity instrument, or project. To accurately estimate the value, it is necessary to estimate future cash flows, adjusted to the present value. The DCF Model discounts future cash flows to the present value, given investor's required rate of return. The value thus established can be then compared to the current market price to assess whether the investment wouldn't be a good deal or not.

Computation of Free Cash Flow

To begin with, the most essential part of the DCF Model is calculation of free cash flow. Free Cash Flow (FCF) is the amount of money a company can generate after deducting all the costs associated with acquiring the asset. This can include cost of capital, cost of production, and any other expenses associated with the asset. The demand for a certain product or service, revenue generated by it, and other economic factors must also be taken into consideration. After calculating free cash flow and other cash flows associated with the asset, they must be discounted to present value by applying the selected discount rate.

Adjusting The Discount Rate

In the DCF Model, the need to adjust the discount rate is often necessary. The discount rate is a rate of return used to determine the present value of the cash flows. This can also be referred to as the required rate of return. This rate is usually adjusted depending on the anticipated risk of investing in the asset. This adjustment to the discount rate can cause different items to appear differently when the formula is applied to determine the present value.

  • The higher the discount rate, the lower the present value of the cash flows.
  • The lower the discount rate, the higher the present value of the cash flows.

Overview of Internal Rate of Return (IRC) Model

An Internal Rate of Return (IRC) model is a financial evaluation metric used to calculate the return of an investment. By measuring the discounted cash flows (DCF) of a potential investment, the IRR is used as a method for comparing cash flow and return on investment. An IRR should never be confused with a rate of return, which measures the appreciation in value of an investment, but rather a measure of the yield on cash flows over the life of an investment. As such, the IRC model is a widely used tool for making investment decisions.

Calculating Net Present Value

Net present value (NPV) is a major component of IRC models, as it is used to determine the present value of an investment. NPV is calculated by taking the discount rate (the cost of capital) and subtracting it from the cash flow. This gives a NPV number that is used as the main metric when calculating an IRC. It is important to remember that when calculating NPV, cash that is received or paid in the future, must be discounted to take into account the opportunity cost of that cash in the current period. In Excel, NPV can be calculated using the NPV function.

Applying the Interest Rate

The IRC model that is calculated using an NPV number is the interest rate that is required to make the NPV of future cash flows equal to zero. In Excel, the IRR function is used to quickly find the IRR of a series of cash flows. Depending on the assumptions made in the project, a certain amount of guesswork and iteration may be required to to achieve the desired IRR. Additionally, the assumptions and cash flows should be adjusted depending on the risk associated with the project.

  • The discount rate used in the NPV calculation can have a major impact on the end IRC value and should be directly related to the risk of the project.
  • It is important to remember that any changes made to the assumptions and cash flow inputs should be accompanied by an adjustment in the discount rate to ensure the validity of the results.

Comparing the Results of Both Models

When considering a DCF and IRC analysis, both models can be used to provide accurate valuation results for a business; however, the results are typically quite different from one another. Firstly, DCF and IRC models each follow a different approach in order to calculate the value or intrinsic worth of a business. Comparing the two models enables one to consider the most appropriate analysis to perform for one’s circumstances and requires one to understand the differences between the two.

Steps to Take

When comparing the results of DCF and IRC models, one should firstly understand the assumptions and advantages of both. Specifically, a DCF analysis is based on estimated future cash flows, while an IRC model is based on current company profits. Additionally, this comparison should also take into account the relevance of the information available and the purpose of the analysis. Once the appropriate assumptions, data, and purpose have been considered and established, potential scenarios can be simulated by changing the inputs to the analysis.

Advantages and Disadvantages

Comparing the results of DCF and IRC models can allow a company to identify the limitations of one model or the other. One advantage of DCF is the ability to incorporate future growth into the analysis. Additionally, cash flows can be more accurately forecasted with DCF when compared to IRC. On the other hand, an IRC model has the power to provide a more current value; however, it may not be very reliable when making the projections based on financial data that was not properly vetted.

Ultimately, a key consideration when choosing either a DCF model or an IRC model is the importance of understanding each model’s respective advantages. Going through the process of comparing the results of the two models can be beneficial in a variety of ways. By performing a comparative analysis, one can better understand the dynamics of both approaches and create more accurate valuations for a business.

Benefits of Using Excel For DCF and IRC Models

Excel is widely used and popular software in the world of finance, offering users the necessary tools to create financial models such as the Discounted Cash Flow (DCF) and Internal Rate of Return (IRC) models. Excel's flexibility and wide range of features make it an ideal choice for creating these models.

Creating the DCF and IRC Models in Excel

DCF (Discounted Cash Flow) and IRC (Internal Rate of Return) modelling in Excel can provide powerful insights into the long-term investment potential of a given project. Excel is typically used to construct these models, as it has the flexibility and scalability to allow intricate financial calculations to be performed quickly and efficiently. In this article, we outline the process of constructing a DCF and IRC model in Excel.

Setting Up the Worksheet

The first step when creating a DCF or IRC model in Excel is to set up the worksheet. This involves determining the exact data that needs to be included in the model, and then creating the necessary columns and rows for the data to be entered into. The exact structure and content of the worksheet will depend on the type of model being created, but it is important to ensure that all relevant data is accounted for, and that the worksheet is correctly formatted for the calculations to be performed correctly.

Entering Assumptions

The next step is to enter the relevant assumptions into the model. This will typically involve forecasting the expected cash flows of the project, as well as any additional factors such as the cost of capital and discount rate. Again, the exact assumptions that need to be included will depend on the type of model being used. It is important to ensure that all assumptions are reasonable and up-to-date, as this will significantly affect the results of the model.

Creating the Output Chart

The final step is to generate the output chart. This can be done by entering the relevant data into the worksheet and then creating a chart from the data. This will allow the results of the model to be visualised and will provide a simple way to evaluate the long-term investment potential of the project.


DCF and IRC models are effective Excel-based financial analysis tools used to evaluate potential investments and make informed decisions. Understanding and utilizing both processes provides a comprehensive evaluation of any given investment, ensuring that all deficiencies, data discrepancies and value variances are accounted for. The result is a comprehensive and reliable analysis of the investment in question.

Final Thoughts on Considerations

When performing a DCF or IRC analysis, it is crucial that analysts use the most accurate and up-to-date data available. As the inputs and assumptions used in these models often change over time, it is essential to use the most recent information whenever possible in order to ensure reliable results. Additionally, analysts should always be mindful of the associated risk in any given investment, as certain risks are not typically accounted for in these models.
