Helps you develop an accurate projection of a projects financial costs and benefits

Are you unsure whether a particular decision is the best one for your business? Are you questioning whether a proposed project will be worth the effort and resources that will go into making it a success? Are you considering making a change to your business, marketing, or sales strategy, knowing that it might have repercussions throughout your organization?

The way that many businesses, organizations, and entrepreneurs answer these, and other, questions is through business analytics—specifically, by conducting a cost-benefit analysis.

A cost-benefit analysis is the process of comparing the projected or estimated costs and benefits (or opportunities) associated with a project decision to determine whether it makes sense from a business perspective.

Generally speaking, cost-benefit analysis involves tallying up all costs of a project or decision and subtracting that amount from the total projected benefits of the project or decision. (Sometimes, this value is represented as a ratio.)

If the projected benefits outweigh the costs, you could argue that the decision is a good one to make. If, on the other hand, the costs outweigh the benefits, then a company may want to rethink the decision or project.

There are enormous economic benefits to running these kinds of analyses before making significant organizational decisions. By doing analyses, you can parse out critical information, such as your organization’s value chain or a project’s ROI.

Cost-benefit analysis is a form of data-driven decision-making most often utilized in business, both at established companies and startups. The basic principles and framework can be applied to virtually any decision-making process, whether business-related or otherwise.

Steps of a Cost-Benefit Analysis

1. Establish a Framework for Your Analysis

For your analysis to be as accurate as possible, you must first establish the framework within which you’re conducting it. What, exactly, this framework looks like will depend on the specifics of your organization.

Identify the goals and objectives you’re trying to address with the proposal. What do you need to accomplish to consider the endeavor a success? This can help you identify and understand your costs and benefits, and will be critical in interpreting the results of your analysis.

Similarly, decide what metric you’ll be using to measure and compare the benefits and costs. To accurately compare the two, both your costs and benefits should be measured in the same “common currency.” This doesn’t need to be an actual currency, but it does frequently involve assigning a dollar amount to each potential cost and benefit.

2. Identify Your Costs and Benefits

Your next step is to sit down and compile two separate lists: One of all of the projected costs, and the other of the expected benefits of the proposed project or action.

When tallying costs, you’ll likely begin with direct costs, which include expenses directly related to the production or development of a product or service (or the implementation of a project or business decision). Labor costs, manufacturing costs, materials costs, and inventory costs are all examples of direct costs.

But it’s also important to go beyond the obvious. There are a few additional costs you must account for:

• Indirect costs: These are typically fixed expenses, such as utilities and rent, that contribute to the overhead of conducting business.
• Intangible costs: These are any current and future costs that are difficult to measure and quantify. Examples may include decreases in productivity levels while a new business process is rolled out, or reduced customer satisfaction after a change in customer service processes that leads to fewer repeat buys.
• Opportunity costs: This refers to lost benefits, or opportunities, that arise when a business pursues one product or strategy over another.

Once those individual costs are identified, it’s equally important to understand the possible benefits of the proposed decision or project. Some of those benefits include:

• Direct: Increased revenue and sales generated from a new product
• Indirect: Increased customer interest in your business or brand
• Intangible: Improved employee morale
• Competitive: Being a first-mover within an industry or vertical

3. Assign a Dollar Amount or Value to Each Cost and Benefit

Once you’ve compiled exhaustive lists of all costs and benefits, you must establish the appropriate monetary units by assigning a dollar amount to each one. If you don’t give all the costs and benefits a value, then it will be difficult to compare them accurately.

Direct costs and benefits will be the easiest to assign a dollar amount to. Indirect and intangible costs and benefits, on the other hand, can be challenging to quantify. That does not mean you shouldn’t try, though; there are many software options and methodologies available for assigning these less-than-obvious values.

4. Tally the Total Value of Benefits and Costs and Compare

Once every cost and benefit has a dollar amount next to it, you can tally up each list and compare the two.

If total benefits outnumber total costs, then there is a business case for you to proceed with the project or decision. If total costs outnumber total benefits, then you may want to reconsider the proposal.

Beyond simply looking at how the total costs and benefits compare, you should also return to the framework established in step one. Does the analysis show you reaching the goals you’ve identified as markers for success, or does it show you falling short?

If the costs outweigh the benefits, ask yourself if there are alternatives to the proposal you haven’t considered. Additionally, you may be able to identify cost reductions that will allow you to reach your goals more affordably while still being effective.

Pros and Cons of Cost-Benefit Analysis

There are many positive reasons a business or organization might choose to leverage cost-benefit analysis as a part of their decision-making process. There are also several potential disadvantages and limitations that should be considered before relying entirely on a cost-benefit analysis.

Advantages of Cost-Benefit Analysis

A Data-Driven Approach

Cost-benefit analysis allows an individual or organization to evaluate a decision or potential project free of biases. As such, it offers an agnostic and evidence-based evaluation of your options, which can help your business become more data-driven and logical.

Makes Decisions Simpler

Business decisions are often complex by nature. By reducing a decision to costs versus benefits, the cost-benefit analysis can make this dilemma less complex.

Uncovers Hidden Costs and Benefits

Cost-benefit analysis forces you to outline every potential cost and benefit associated with a project, which can uncover less-than-obvious factors like indirect or intangible costs.

Limitations of Cost-Benefit Analysis

Difficult to Predict All Variables

While cost-benefit analysis can help you outline the projected costs and benefits associated with a business decision, it’s challenging to predict all the factors that may impact the outcome. Changes in market demand, material costs, and the global business environment are unpredictable—especially in the long term.

Incorrect Data Can Skew Results

If you’re relying on incomplete or inaccurate data to finish your cost-benefit analysis, the results of the analysis will follow suit.

Better Suited to Short- and Mid-Length Projects

For projects or business decisions that involve longer timeframes, cost-benefit analysis has a greater potential of missing the mark for several reasons. For one, it’s typically more difficult to make accurate predictions the further into the future you go. It’s also possible that long-term forecasts won’t accurately account for variables such as inflation, which can impact the overall accuracy of the analysis.

Removes the Human Element

While a desire to make a profit drives most companies, there are other, non-monetary reasons an organization might decide to pursue a project or decision. In these cases, it can be difficult to reconcile moral or “human” perspectives with the business case.

In the end, cost-benefit analysis shouldn't be the only business analytics tool or strategy you use in determining how to move your organization into the future. Cost-benefit analysis isn’t the only type of economic analysis you can do to assess your business’s economic state, but a single option at your disposal.
