How to do a cost-benefit analysis


Cost-benefit analysis, or CBA, is a procedure or instrument used to aid in making project-related decisions. CBA assesses a project’s cost vs benefit to establish project viability (how significantly the benefit overcomes the price) and to offer decision-making criteria when considering numerous possibilities.

What is the Meaning of a Cost-Benefit Analysis?

cost-benefit analysis is systematic procedure organisations use to determine which to implement and which to avoid. The cost-benefit analyst adds the possible rewards of a scenario or activity and then deducts the overall expenses of pursuing that activity. Some experts or analysts may create models to give monetary value to intangible elements such as the advantages and costs of living in a specific area.

The Cost-Benefit Analysis is an example of a cost-benefit ratio. Assume there are two activities, one accruing an overall price of Rs. 8,000 and getting paid a benefit of Rs 12,000, while the other accruing expenses of Rs. 11,000 and getting paid a benefit of Rs 20,000. Using cost-benefit analysis, the cost-benefit ratio of the first task is 1.5 (Rs 8,000/Rs 12,000), and the ratio of the 2nd part is 1.81 (Rs11,000/Rs20,000).

How to Do a Cost-Benefit Analysis?

A cost-benefit analysis, also known as a cost-savings analysis, is crucial in determining whether to proceed with a fresh idea or proposal. 

1. Recognise the Cost of Sustaining the Established Order

This stage helps you comprehend the possible expenses associated with doing nothing and might help you assess whether starting a new project is viable. Performing nothing is sometimes the best choice. On the contrary, doing nothing might result in disaster if anyone lags behind his competing products; doing nothing may cost him more than investing.

2. Determine the Costs

Spend some time thinking about the project’s expenses. Make a complete list of all costs that may have an influence, such as: –

  • Initial expenses
  • Unexpected expenses
  • Actual costs
  • Collateral expenses
  • Current or future expenses
  • Any possible hazards that might result in a cost

3. Determine the Advantages

Determine the possible benefits of moving on with the project at this stage. Consider the following questions: –

  • What additional income will the investment generate?
  • What is the expected investment’s return? Explain what ROI implies to the business—perhaps anyone assesses ROI in revenue, productivity, or customer base. List the advantages connected with ROI, whatever you define it.
  • Determine how far ahead a person should look to find long-term advantages. 

4. Give the Expenses and Benefits a Financial Value

All expenses and benefits must be calculated with the same unit of currency. If anyone undertakes a cost-benefit analysis for a multinational corporation, don’t try to divide project expenses into multiple categories based on location or country. Using the same money for everything is much simpler to record actual costs and profits.

5. Make a Schedule of Estimated Expenses and Revenue

Plan out when and how much you anticipate the fees and advantages to materialise. The timeline assists users in aligning, defining, and tracking the objectives of all parties involved. Furthermore, the timeframe may help you prepare for future expenses and income implications, allowing users to monitor and modify as things change.

6. Costs and Advantages Should Be Weighed

Depending on the categories, estimate the total expenditure and absolute benefits. Utilise the same denomination in all of your calculations. Users can see if the benefits exceed the drawbacks when comparing the two figures.

Importance of Choosing an Online School Using Cost-Benefit Analysis

cost-benefit analysis of economics is a straightforward idea. Cost-benefit analysis is used to understand better whether the online school is right for professional and educational objectives by knowing more about its benefits and drawbacks.

  • Evaluate Your Attendance Charges

Calculate the expenses of attendance for every institution and investigate to begin the cost comparison. Together with tuition costs, include living expenditures like housing and breakfast, healthy meals, textbooks, and any additional fees. While one school may have cheaper tuition costs than the other, the attendance costs may increase if it is situated in a costly metropolitan city instead of a more inexpensive rural place.

  • Consider Financial Help and Student Loans

Examine your financial support offers more closely after determining the attendance costs for each institution. Your financial assistance package may contain grants and fellowships that you do not have to repay and student loans.

Examine the specifics of your financial assistance plan at each school so you understand how often each one will pay you, both currently and in the future, and continue to submit grants and fellowships to lower the amount you’ll have to spend on student loan debt.

  • Take into Account Graduation and Persistence Rates

Once you’ve gained a better knowledge of the expenses of education, it’s time to consider the advantages. One approach to assess a school’s worth is to examine its degree and performance rates.

Graduation rates indicate how several students graduate, whereas retention reveals how many students remain each year and how many move or quit.


There are several reasons to do a cost-benefit analysis. The method is based on data-driven judgment; each proposed conclusion is based on measurable facts explicitly acquired for a particular situation.

In general, cost-benefit analysis economics entails totalling all expenses associated with a project or choice and deducting that cost from the entire predicted benefits of the program or judgment. For more information about cost-benefit analysis, visit the 21K School platform.
