What is Discounted Cash Flows (DCF)?
Discounted Cash Flows (DCF) is a valuation method used in finance and investment analysis to estimate the intrinsic value of an investment, business, or project. It is based on the principle that the value of money today is worth more than the same amount of money in the future due to factors such as inflation, opportunity costs, and risk.
The Discounted Cash Flow or DCF analysis involves projecting the future cash flows generated by the investment or project and then discounting those cash flows back to their present value using a discount rate. The discount rate accounts for the time value of money and reflects the risk associated with the investment.
What is Discounted Cash Flows Used For
DCF (Discounted Cash Flow) analysis is a widely used financial valuation method with various applications in finance, investment analysis, and business decision-making. Some of the key uses of DCF include:
- Valuing Investments: Discounted Cash Flow or DCF is commonly used to determine the intrinsic value of stocks, bonds, and other financial assets. By calculating the present value of the expected future cash flows generated by the investment, analysts can assess whether an asset is overvalued or undervalued in the market.
- Business Valuation: Discounted Cash Flow analysis is employed to estimate the value of an entire business or a specific business segment. By projecting future cash flows and discounting them back to their present value, business owners and investors can gauge the worth of the business and make informed decisions regarding mergers, acquisitions, or divestitures.
- Project Evaluation: Discounted Cash Flow is used to assess the financial viability of potential projects or investments. By comparing the present value of expected project cash flows to the initial investment cost, decision-makers can determine whether a project is likely to generate a positive return.
- Capital Budgeting: DCF is an essential tool in capital budgeting decisions, helping companies choose between different investment opportunities. By analysing the present value of cash flows associated with different projects, organizations can prioritize investments and allocate capital more efficiently.
- Asset and Equipment Purchases: Businesses often use DCF to evaluate the purchase of expensive assets or equipment. The analysis helps them determine whether the expected future cash flows from the asset justify the initial investment.
- Strategic Decision-Making: DCF aids in strategic planning, helping companies understand the long-term financial implications of their decisions. Whether it's expanding into new markets, launching new products, or making operational changes, DCF can provide valuable insights into potential outcomes.
- Performance Evaluation: Companies can use DCF to assess the financial performance of projects or investments over time. By comparing the original DCF analysis with the actual cash flows, organizations can identify areas of improvement and refine their decision-making processes.
Overall, DCF is a versatile and powerful tool that aids in financial analysis, investment decisions, and strategic planning, providing valuable insights into the future cash flow potential of various investments and projects. However, it's important to recognize that DCF analysis relies on projections and assumptions, so it should be used in conjunction with other valuation methods and be based on robust and well-founded data.
How DCF (Discounted Cash flow) Model Work
- Forecast Future Cash Flows: The first step is to forecast the expected future cash flows generated by the investment or project. Projections typically include revenues, expenses, taxes, and other cash inflows and outflows.
- Determine the Discount Rate: The discount rate is a critical component of DCF Model and represents the rate of return required by an investor to invest in the project or asset. It accounts for the time value of money and reflects the risk associated with the investment. The discount rate is often based on the cost of capital or the rate of return expected from similar investments with similar risk profiles.
- Calculate the Present Value: Each projected future cash flow is then discounted back to its present value using the discount rate. The formula for calculating the present value of a future cash flow is as follows:
Present Value (PV) = Cash Flow / (1 + Discount Rate)n
- PV is the present value of the cash flow
- Cash Flow is the expected cash flow in a specific period
- Discount Rate is the rate used to discount the future cash flows
- n is the time period for which the cash flow is projected.
- Sum Up the Present Values: Once all the future cash flows have been discounted to their present values, they are added together to arrive at the total present value.
- Compare to Initial Investment: Finally, the total present value is compared to the initial investment or cost of the project. If the total present value is higher than the initial investment, the project is considered financially viable and may be considered for investment. Conversely, if the total present value is lower than the initial investment, the project may not be a favourable investment.
Essential Insights from DCF Analysis
- DCF assesses investment value via future cash flows, calculating present value using a projected discount rate. If DCF surpasses current investment cost, it suggests potential for positive returns.
- WACC, reflecting shareholder return, is often used as the discount rate. However, DCF's drawback lies in its dependence on future cash flow estimations, which might be imprecise.
How to calculate discounted cash flow?
Discounted Cash Flow Formula
The basic formula for calculating the present value of cash flows using DCF is as follows:
Present Value (PV) = Cash Flow / (1 + Discount Rate)n
Where:
- PV is the present value of the cash flow
- Cash Flow is the expected cash flow in a specific period
- Discount Rate is the rate used to discount the future cash flows
- n is the time period for which the cash flow is projected.
Example of Discounted Cash Flow
Table 1 demonstrates the computation of the Present Value of Cash Flows for a forecast period of 5 years with a discount rate of 11% and the present value of terminal value.
Table 1
| Year | 1 | 2 | 3 | 4 | 5 |
| Cash Flow | 1000 | 1500 | 2000 | 2500 | 3000 |
| 11% Discount Factor | 0.901 | 0.812 | 0.731 | 0.659 | 0.593 |
| Present Value of Cash Flow | 900.90 | 1217.40 | 1462.40 | 1646.80 | 1780.40 |
| Cumulative PV of Cash Flow | 900.90 | 2118.30 | 3580.70 | 5227.50 | 7007.90 |
| Inflation | 2% | ||||
| WACC | 11% | ||||
| Discount Factor | 1/(1.11)n | ||||
| Cumulative Present Value of Cash Flow | 7007 |
| Present Value of Terminal Value | 20178 |
| Debt & Obligations | 1000 |
| Intrinsic / Shareholder Value | 26185 |
Notes:
- The computation of terminal values assumes there will be only inflationary growth in cash flows.
- The computation of terminal value will be explained in Chapter 18 of the book.
- Readers should read Chapter 4 - Time Value of Money and Discount Factor for better understanding of discounting and terminal value.
What is the difference between Discounted Cash Flows and NPV
Discounted Cash Flows (DCF) and Net Present Value (NPV) are closely related concepts used in finance and investment analysis to determine the value of an investment or project. Both methods involve calculating the present value of future cash flows, but they are used for slightly different purposes.
Discounted Cash Flows (DCF): DCF is a valuation method that estimates the present value of future cash flows generated by an investment or project. It considers the time value of money, recognizing that money today is worth more than the same amount of money in the future due to factors like inflation and opportunity costs.
In DCF analysis, the future cash flows are projected, and each cash flow is discounted back to its present value using a discount rate. The discount rate reflects the required rate of return or the cost of capital, taking into account the risk associated with the investment. By summing up the present values of all future cash flows, you can determine the total present value of the investment or project.
The primary goal of DCF is to assess the financial viability of an investment or project. If the total present value of cash flows is positive (greater than the initial investment cost), the investment is considered potentially profitable.
Net Present Value (NPV): NPV is a financial metric used to evaluate the profitability of an investment or project. It represents the difference between the present value of cash inflows and outflows over a specific period. In other words, NPV quantifies the net contribution of an investment to an entity's wealth.
To calculate NPV, the initial investment cost is subtracted from the sum of the present values of future cash inflows and outflows. A positive NPV indicates that the investment is expected to generate positive returns and add value to the entity. Conversely, a negative NPV suggests that the investment is not expected to meet the required rate of return and may not be financially feasible.
NPV is an important tool for investment decision-making, as it helps determine whether an investment will yield positive returns after accounting for the time value of money.
In summary, DCF is a valuation method used to estimate the total present value of future cash flows, while NPV is a financial metric that evaluates the profitability of an investment by comparing the present value of inflows and outflows. Both DCF and NPV are essential tools for assessing the financial viability and profitability of investments or projects.
