by A cost-benefit analysis is a systematic process that businesses use to analyze which decisions to make and which to forgo. The cost-benefit analyst sums the potential rewards expected from a situation or action and then subtracts the total costs associated with taking that action. Some consultants or analysts also build models to assign a dollar value on intangible items, such as the benefits and costs associated with living in a certain town.
Before building a new plant or taking on a new project, prudent managers conduct a cost-benefit analysis to evaluate all the potential costs and revenues that a company might generate from the project. The outcome of the analysis will determine whether the project is financially feasible or if the company should pursue another project.
In many models, a cost-benefit analysis will also factor the opportunity cost into the decision-making process. Opportunity costs are alternative benefits that could have been realized when choosing one alternative over another. In other words, the opportunity cost is the forgone or missed opportunity as a result of a choice or decision. Factoring in opportunity costs allows project managers to weigh the benefits from alternative courses of action and not merely the current path or choice being considered in the cost-benefit analysis.
By considering all options and the potential missed opportunities, the cost-benefit analysis is more thorough and allows for better decision-making.
The Cost-Benefit Analysis Process
A cost-benefit analysis should begin with compiling a comprehensive list of all the costs and benefits associated with the project or decision.
The costs involved in a CBA might include the following:
- Direct costs would be direct labor involved in manufacturing, inventory, raw materials, manufacturing expenses.
- Indirect costs might include electricity, overhead costs from management, rent, utilities.
- Intangible costs of a decision, such as the impact on customers, employees, or delivery times.
- Opportunity costs such as alternative investments, or buying a plant versus building one.
- Cost of potential risks such as regulatory risks, competition, and environmental impacts.
Advantages:
- Higher revenue and sales from increased production or new product.
- Intangible benefits, such as improved employee safety and morale, as well as customer satisfaction due to enhanced product offerings or faster delivery.
- Competitive advantage or market share gained as a result of the decision.
An analyst or project manager should apply a monetary measurement to all of the items on the cost-benefit list, taking special care not to underestimate costs or overestimate benefits. A conservative approach with a conscious effort to avoid any subjective tendencies when calculating estimates is best suited when assigning a value to both costs and benefits for a cost-benefit analysis.
Finally, the results of the aggregate costs and benefits should be compared quantitatively to determine if the benefits outweigh the costs. If so, then the rational decision is to go forward with the project. If not, the business should review the project to see if it can make adjustments to either increase benefits or decrease costs to make the project viable. Otherwise, the company should likely avoid the project.
The Purpose of Cost-Benefit Analysis
The purpose of cost-benefit analysis in project management is to have a systemic approach to figure out the pluses and minuses of various paths through a project, including transactions, tasks, business requirements and investments. The cost-benefit analysis gives you options, and it offers the best approach to achieve your goal while saving on investment.
There are two main purposes in using CBA:
- To determine if the project business case is sound, justifiable and feasible by figuring out if its benefits outweigh costs.
- To offer a baseline for comparing projects by determining which project’s benefits are greater than its costs.
Limitations of the Cost-Benefit Analysis
For projects that involve small- to mid-level capital expenditures and are short to intermediate in terms of time to completion, an in-depth cost-benefit analysis may be sufficient enough to make a well-informed, rational decision. For very large projects with a long-term time horizon, a cost-benefit analysis might fail to account for important financial concerns such as inflation, interest rates, varying cash flows, and the present value of money.
Alternative capital budgeting analysis methods, including net present value (NPV), could be more appropriate for these situations. The concept of present value states that an amount of money or cash in the present day is worth more than receiving the amount in the future since today’s money could be invested and earn income.
One of the benefits of using the net present value for deciding on a project is that it uses an alternative rate of return that could be earned if the project had never been done. That return is discounted from the results. In other words, the project needs to earn at least more than the rate of return that could be earned elsewhere or the discount rate.
However, with any type of model used in performing a cost-benefit analysis, there are a significant number of forecasts built into the models. The forecasts used in any CBA might include future revenue or sales, alternative rates of return, expected costs, and expected future cash flows. If one or two of the forecasts are off, the CBA results would likely be thrown into question, thus highlighting the limitations in performing a cost-benefit analysis.
Efficient Investment Analysis
Investment analysis is a broad term for many different methods of evaluating investments, industry sectors, and economic trends. It can include charting past returns to predict future performance, selecting the type of investment that best suits an investor’s needs, or evaluating individual securities such as stocks and bonds to determine their risks, yield potential, or price movements. Investment analysis is key to a sound portfolio management strategy.
The aim of investment analysis is to determine how an investment is likely to perform and how suitable it is for a particular investor. Key factors in investment analysis include the appropriate entry price, the expected time horizon for holding an investment, and the role the investment will play in the portfolio as a whole.
In conducting an investment analysis of a mutual fund, for example, an investor looks at how the fund performed over time compared to its benchmark and to its main competitors. Peer fund comparison includes investigating the differences in performance, expense ratios, management stability, sector weighting, investment style, and asset allocation.
