How to Perform a Cost-Benefit Analysis
A cost-benefit analysis (CBA) is essential for anyone making business decisions, managing projects, or creating policies. It helps you evaluate how much something will cost versus the benefits you expect to gain so you can make smarter, more informed choices.
This guide will show you how to quickly conduct a cost-benefit analysis, considering an investment, a new project, or a policy change.
A cost-benefit analysis compares a decision’s costs with its benefits to determine whether they are worth the costs. This process is helpful when resources are limited, and you want to ensure that you make the best decision for the future.
Example: Imagine your company is thinking about buying new software. A cost-benefit analysis would compare the price of the software to the benefits, like more productivity, lower labor costs, or better customer service. If the benefits are higher than the costs, the investment makes sense.

Please enter costs and benefits to calculate the result.
Some time recently, you can calculate the benefits; you are required to list all the costs included. These are coordinated or backhanded, short-term or long-term. Begin by composing down each conceivable cost.
Example: In the software case, direct costs include the price of the software and the cost of installation and training. Indirect costs could be employees’ time learning how to use the new software.

You must consider the benefits now that you’ve listed all the costs. These can be tangible (easy to measure) or intangible (more challenging but still meaningful).
Example: The computer program might bring significant benefits, like higher productivity or diminished labor costs. Intangible benefits include ways to improve group resolve or progress client advantage.
For a deeper dive into tangible vs. intangible benefits, check out this article in Harvard Business Review.
Once you’ve identified the costs and benefits, the next step is to assign a dollar amount to each one. Some benefits, especially intangibles, may be hard to quantify, but giving them a realistic value is essential. Base your estimates on reliable data, like industry standards or expert advice.
Example: If the software costs $10,000 to purchase and $1,000 per year for maintenance, and it’s expected to save $15,000 annually in labor costs, the return on investment is easily visible.
You can use Excel or Google Sheets to create a simple financial model.
Now that you’ve assigned values to costs and benefits, compare them. This is the core of the cost-benefit analysis. If the benefits exceed the costs, the project is likely worth pursuing. You can find the net benefit by subtracting total expenses from total benefits.

Example: If the computer program costs $10,000 but passes on $15,000 in benefits yearly, the net advantage is $5,000 yearly. If the costs and benefits are comparable, other components, like chance or key destinations, might affect your choice.

In 2025, the U.S. Department of Energy reported that municipalities investing in solar power saw an average return of 15% annually through energy savings and economic growth. This shows how a well-done cost-benefit analysis can lead to innovative, sustainable decisions.
After comparing the costs and benefits, you’ll be ready to decide. If the benefits clearly outweigh the costs, go ahead with the project. But if the costs outweigh the benefits, you should rethink it or consider alternatives.
Example: If the computer program offers a strong return on investment, it makes sense to proceed. If the benefits are negligible or short-lived, it might be best to delay the choice or look for another program arrangement.

To see how a cost-benefit analysis works, consider this example of a local government deciding whether to invest in renewable energy like solar power.

Q4. How do I perform a sensitivity analysis?
A4. Sensitivity analysis helps you understand how changes in your assumptions (like cost or benefit values) affect the overall result. Adjusting the numbers slightly lets you see how sensitive your outcome is to changes. More on sensitivity analysis here.
Q5. What should I do if the costs outweigh the benefits?
A5. If the fees exceed the benefits, it may be a poor investment. But before deciding, consider non-financial factors or explore ways to reduce costs or increase benefits.
