What is a Cost-Benefit Analysis?
Cost-benefit analysis (CBA) is a systematic approach to estimating the strengths and weaknesses of alternatives that satisfy a business’s transactions, activities, or functional requirements. It is an analytical tool used to determine the viability of a project or decision by comparing its pros and cons.
Depending on the type of situation you’re evaluating, a cost-benefit analysis could consider either tangible or intangible costs and benefits.
- Tangible costs are direct costs you can easily quantify, such as labor, materials, and equipment expenses.
- Intangible costs are indirect costs and potential risks you can’t quantify as easily, including opportunity costs and lost productivity.
- Tangible benefits are those that have a specific monetary value, such as revenue generated, cost savings, or return on investment.
- Intangible benefits are non-monetary gains, such as improved customer satisfaction or increased employee morale.
In the decision-making process, there are always trade-offs. A cost-benefit analysis is all about determining whether a particular decision’s benefits are worth those trade-offs. It helps organizations evaluate the potential impact of a decision on their resources and determine if it aligns with their goals and objectives.

Purpose of Cost-Benefit Analysis in Business
The purpose of a cost-benefit analysis is simple: determine options that provide the best approach to achieving business results while preserving savings. It helps business leaders make high-level decisions by evaluating the potential costs and benefits of each alternative. It also helps them identify any unforeseen consequences that may arise from a decision.
The findings from a cost-benefit analysis tell stakeholders and management/exec teams important information, like:
- Whether a project is financially viable
- How much budget to allocate for the project
- Project prioritization and resource allocation
- The potential return on investment (ROI) for the project
- Which projects would receive less priority as a result
- How the project could impact their customers or employees
- Potential risks and challenges associated with the project
A cost-benefit analysis provides a structured approach to decision-making, making it easier for businesses to justify their choices and communicate them effectively to stakeholders. It’s subjective, but it relies on objective data to make informed decisions. As a result, it reduces bias in decision-making and encourages organizations to make well-informed choices.
Common Business Use Cases for Cost-Benefit Analysis
Depending on the nature of your business, the exact application of cost-benefit analysis will vary. For instance, a SaaS company might use it to determine which product features will are worth developing. A manufacturing company might use CBA to evaluate potential investments in new equipment or facility locations.
Here are some common business scenarios where cost-benefit analysis comes into play:
Governments use cost-benefit analysis to evaluate infrastructure projects, such as building new roads or bridges. Since they have limited budgets for public infrastructure, they have to consider where the investment will be best for the local (and, by extension, national) economy.
Governments often contract private businesses to carry out these types of projects. Every company is largely reliant on manpower and overall costs, so they need perform a CBA to ensure each project will be sustainable and profitable for them.
Implementing new technology is always expensive. For example, switching CRMs could cost as much as $145 per user, plus tens of thousands in implementation fees.
Beyond the significant costs of implementing new software or switching from an old one, there’s non-monetary considerations. User adoption, data migration, and training are just some of the factors that need to be taken into account.
So companies perform a cost-benefit analysis that compares the potential long-term upside to the upfront investment of time and money. Ultimately, it usually comes down to whether their current problem is so severe that it warrants the risk of adopting a new technology.
New Product Development
One of the biggest challenges for software companies is allocating development resources to building new features for their existing products. When it comes down to prioritizing which features will make the cut, companies often rely on a cost-benefit analysis.
Some factors that might affect the decision could include:
- Market demand for the feature
- The level of effort required to build it
- Potential revenue impact
- Development resources required
Customers also play a significant role in this evaluation. If a significant enough proportion of current and potential customers ask for a specific feature, it’s more likely to be prioritized despite the investment requirement. In cases like those, lower customer retention could be much more costly than the resources required to build the feature.
Business Expansion and Investment
Expanding operations, entering new markets, and investing in R&D are all potentially risky endeavors. Their financial implications can be significant, so companies usually rely on a cost-benefit analysis to ensure they are making informed decisions.
Factors that could influence their decision might include:
- The total addressable market
- The potential return on investment (ROI) from that market
- Potential risks and challenges associated with the venture
- Existing competition
- Additional sales and marketing infrastructure and expected costs
- Scalability of the project
A company generally invests in expansion or diversification when there’s a large enough total addressable market that there’s room for sustainable competition. If the market isn’t big enough or it’s too competitive, they might choose to prioritize other projects with smaller but more certain returns.
Risk management is, in a lot of ways, based on cost-benefit analysis. The whole point of risk management processes is to weigh the cost of potential losses (and their probabilities) against the cost of safeguarding yourself against them.
There are several ways you could use cost-benefit analysis in risk management, depending on the specific situation. These might include:
- Evaluating different insurance policies
- Deciding whether to invest in cybersecurity systems
- Implementing safety protocols
- Protecting customer data
- Dealing with market volatility
In highly regulated industries like finance and healthcare, certain risks (e.g., data security) are more pressing than they would be for businesses that use less sensitive data. The same goes for enterprise companies, which are commonly targets of cyberattacks.
Mergers and Acquisitions
M&A deals are among the most thought-out and well-planned projects in a company’s lifecycle. They require significant resources, time, and careful consideration, which normally take anywhere from 6 months to several years.
Common elements of M&A cost-benefit analyses include:
- The purchase price of the other company
- Integration costs (culture, systems, and personnel)
- Market growth potential from the acquisition
- Potential cost savings or synergies
- Competitive advantages the deal creates for the acquiring company
- The likelihood of the deal succeeding (due diligence)
Companies also perform a CBA when considering whether to divest certain business lines. They evaluate whether the lines are underperforming so much that it would be more beneficial for them long-term to sell them off, versus keeping and investing in them.
Cost-Benefit Analysis Steps
While the specific steps may vary slightly depending on the context and source, a commonly accepted cost-benefit analysis framework includes the following seven steps:
1. Define the scope and objectives.
Your “scope” is the problem you’re looking to solve, or the opportunity you want to evaluate. The “objectives” are what you hope to gain out of solving that problem or taking advantage of that opportunity.
“We are looking to evaluate the potential investment in a new CRM system to improve our sales processes. Our objectives are to increase efficiency, reduce costs by 10%, and ultimately drive 20% more revenue post-implementation.”
This first step assumes you’ve already identified a problem or opportunity and are considering different solutions. If you’re trying to develop new product ideas, this step would be more about defining the market opportunity and your ideal customer profile.
2. Identify all your alternatives.
There is always more than one option when it comes to solving a problem or pursuing an opportunity. Once you know what your objectives are, consider all the different ways to meet them.
Using the example from above, increasing efficiency, reducing costs, and driving more revenue are all achievable in a number of ways. In addition to switching CRMs, you could:
- Implement sales automation technology
- Use a different sales framework that cuts down deal cycle time
- Invest in different marketing collateral
- Roll out new products/features
- Reduce/raise prices
- Hire/let go of more salespeople
You should also consider what might happen if you stick to the status quo. Doing nothing is always an option, and you might decide that a certain initiative (e.g., switching CRMs) isn’t worth the effort and costs associated with it.
Identify and list all relevant alternatives or options that could meet the defined objectives.- Consider a range of options, including the status quo or “do nothing” scenario.
3. Specify costs and benefits.
All your alternatives will have their own set of benefits and drawbacks. You’re probably considering investing in multiple growth initiatives at once, so this is where you’ll evaluate which ones are the most viable for your busienss at present.
For that, you’ll need:
- Relevant metrics
- Employee feedback
- Customer feedback
- Trends analyses
- Cost figures for software/infrastructure/tools
- Estimations on time/personnel costs
- Market data
Continuing with the example from above, if you were to consider switching CRMs as a means of becoming more efficient, cutting costs, and selling more, you’d have to consider:
- Sales metrics like lead velocity and sales cycle length
- Employee feedback on the current system
- Customer feedback on your current sales and customer success process
- Trends (e.g., are others on your space switching away from a legacy system?)
- Total implementation, maintenance, and per-user subscription costs of the new CRM
- Time to implementation and time to value
- Level of involvement in the rollout
- Risks associated with data migration and integration with other systems
- Any potential disruption to sales and customer success activities during the implementation process.
If you’re having problems with your current system and your customers and employees are telling you they can’t stand it, it’s probably a lot more worth the investment than if it were a purely cost-based decision.
This is how every business decision is made. A CBA reveals a good decision when there are multiple glaring benefits and few potential drawbacks. It’s much less likely you will “randomly” stumble upon a particular solution to a problem.
4. Monetize your costs and benefits.
The financial implications for some of your costs/benefits will be very obvious. The cost of implementing software, for example, is simple to estimate (a sales rep will do it for you).
But, you have to consider the costs of:
- Not acting on the issue
- Things not working out as planned
- Opportunity cost of investing in one initiative versus another
- Long-term customer satisfaction and churn
- Lifetime value of each deal saved/improved
- Long-term scalability and revenue potential from the initiative
You’re going to find that most costs have direct (often hidden) impact on business growth. Using forecasting models can help you assess the potential upside and downside of different issues where the financial implications are not immediately obvious.
5. Discount future costs and benefits.
In any cost-benefit analysis, you have to account for time value for money by adjusting future costs and benefits to their current values. This will help you make comparisons between options with different timeframes for realization.
The generally agreed-upon discount rate for cost-benefit analyses is 7%. But the exact situation and availability of certain data might tell you to use a rate that’s higher or lower.
6. Calculate Net Present Value (NPV).
The net present value (NPV) calculation takes all your costs and benefits and makes it into a single number representing the expected financial impact of each individual option. It’s practially universally used in finance.
The calculation is as follows:
NPV = ((∑(Benefits – Costs) / (1 + Discount Rate)^Time) – Initial Investment
TO calculate NPV in a cost-benefit analysis context, take the sum of the present values of all inflows and outflows over the investment’s life. What do your numbers look like once adjusted for the discount rate over time?
A negative NPV means that the investment is not expected to generate a positive return, while a positive NPV suggests it will.
Note: The higher the value of NPV, the better. And a “good” NPV is > 0.
7. Conduct a sensitivity analysis before making a decision.
To see how changes in key assumptions affect the results of your analysis, conduct a sensitivity test. This type of analysis is also referred to as a “what-if” analysis, and it allows you to see how changing one variable affects the outcome.
For example, let’s say you’re considering investing in a new marketing campaign. You believe this will increase sales by 20%, but your ROI calculation assumes only a 10% increase. Conducting a sensitivity test can help you see how sensitive your investment is to this assumption.
To conduct a sensitivity analysis, identify the key variables in your cost-benefit analysis and change each variable one at a time while keeping the other variables constant. This will help you see how each individual variable impacts the overall outcome of your analysis, and its level of uncertainty.
From there, you’re ready to make an educated decision.
Challenges and Limitations of Cost-Benefit Analysis
Like any other decision-making tool, there’s a certain level of uncertainty when using a cost-benefit analysis. The accuracy of your analysis will only be as good as the data and assumptions you use. And, relying too heavily on numbers alone can overlook qualitative factors that could greatly impact the true value of a decision.
Broadly, here are the most pressing challenges and limitations of cost-benefit analyses:
- Data accuracy and completeness
- Quantifying intangible factors such as environmental impact, social welfare, employee morale, and customer satisfaction
- Subjectivity, especially in evaluating costs and benefits, which can lead to bias
- The distributional impacts of a decision (e.g., if it disproportionately affects certain groups or communities)
- Uncertainty, since it’s based on assumptions and predictions about the future
- Market fallibility, such as monopolies or market distortions due to government interventions
- Discount rates and time horizons that might undervalue or overestimate long-term benefits
- The dynamic nature of markets and economies, particularly factors like inflation and interest rates, that shift cost-benefit balance over time
- Optimism bias and strategic misrepresentation in early project development, where costs are underestimated, and benefits are overestimated
Cost-Benefit Analysis Examples
SaaS M&A Deal
A large SaaS company is looking to acquire a smaller competitor, but they need to determine if the acquisition will generate positive returns for shareholders and the company itself.
Some potential costs and benefits of this deal include:
- Acquisition price and company valuation
- Integration costs (e.g., merging systems, staff training)
- Increased overhead costs (e.g., salaries, office space)
- Synergies and efficiencies gained by combining resources
- Increased market share and customer base
- Potential for new products or services from the acquired company
If the company has a specific software or feature that could dramatically improve the acquirer’s product offering, it might be worth paying a higher price. However, if the acquisition only results in incremental growth and higher costs, the analysis could suggest acquiring the company isn’t a great idea.
B2B Manufacturer Facility Investment
A prominent manufacturing company is facing the decision of whether to invest in a new facility or upgrade their existing one.
Some potential costs and benefits of this investment include:
- Construction or renovation costs
- Increased production capacity and efficiency
- Lower maintenance costs for the new facility
- Taxes (property and income) in the new facility’s location
- Employee training and relocation costs
- Potential for increased revenue from new products, production capabilities, and markets
- Existing purchase orders that prove the demand and need for a new facility
- Additional opportunities (e.g., contract manufacturing for competitors with less infrastructure)
In this case, the analysis will need to weigh the upfront costs of building a new facility against the potential long-term benefits, such as increased production capacity and efficiency. If demand increases aren’t expected to offset the initial costs, it probab;y won’t be profitable. If they are, it’s potentially a fantastic way to capture more market share and leverage economies of scale.
Key Takeaways on Cost-Benefit Analysis
By understanding the potential costs and benefits of different options, you can select those that are likely to have the most positive impact on your business while minimizing risks and uncertainties.
Some key takeaways to keep in mind when conducting a cost-benefit analysis include:
- Always consider both quantifiable and qualitative costs and benefits.
- Don’t rely solely on numbers; account for intangible factors.
- Review the results of a sensitivity analysis to understand how changing assumptions can affect the outcome.
- Be aware of the challenges and limitations of cost-benefit analyses, such as data accuracy, subjectivity, and uncertainty.
- Use cost-benefit analysis in real-life scenarios like M&A deals and facility investments to make more informed decisions.
- Remember that the goal of a cost-benefit analysis is to help you choose the option with the highest net benefit, not necessarily the cheapest or most profitable.
People Also Ask
Why is cost-benefit analysis important?
Cost-benefit analysis is important because it helps decision-makers weigh the advantages and disadvantages of a course of action. It allows them to carefully decide whether the potential upside of a project or investment versus its downside. This makes for an overall less risky decision.
What are the pros and cons of cost-benefit analysis?
The most significant “pro” of cost-benefit analysis is it assigns monetary value to intangible things like environmental or social impacts. The main “con” is that it’s difficult to accurately measure and account for all costs and benefits, especially when considering long-term effects. Additionally, cost-benefit analysis can be biased if decision-makers have a personal stake in the outcome.
