Cost benefit analysis

Because decisions about safety investments involve choices between different possible risk management options, cost-benefit analysis can be very useful. Moreover, decisions may not be straightforward in some cases, especially in the process industries, where there are important risks to be managed and controlled. Cost-benefit analysis is used to determine whether an investment represents an efficient use of resources. An investment project regarding prevention represents an allocation of means (money, time, etc.) in the present that will result in a particular stream of hypothetical benefits in the future.

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. Identify the goals and objectives you’re trying to address with the proposal. This can help you identify and understand your costs and benefits, and will be critical in interpreting the results of your analysis. 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.


In addition, it’s advisable to conduct a sensitivity analysis to evaluate different scenarios and how those affect your cost-benefit analysis. These costs and benefits are then assigned a monetary value and used to determine the cost-benefit ratio. However, a cost-benefit analysis might also involve other calculations such as return on investment (ROI), internal rate of return (IRR), net present value (NPV) and the payback period (PBP). These criticisms continued under the Clinton administration during the 1990s. Some analysts oppose the use of CBA in policy-making, and those in favor of it support improvements in analysis and calculations.

Think advancing sustainability objectives, diversity and inclusion initiatives and helping employees navigate new workplace realities. Businesses perform cost-benefit analyses to help leaders remove emotion from assessments and provide an apples-to-apples Cost benefit analysis basis to compare competing priorities. And, when intangible benefits are expressed as a “benefits value,” with dollar amounts assigned, that helps finance calculate a break-even point — the time it takes for a product’s or purchase’s benefits to exceed the cost. This type of economic analysis also takes some time to complete, so it’s best for when you’re faced with a big decision that will impact your team or project success.

Since it’s based on adding positive factors and subtracting negative ones to get a net result, it is also known as running the numbers. Cost–benefit analysis (CBA) is an analytical technique for measuring the economic efficiency of public actions by summarizing positive and negative economic effects to a common measure, typically money. Finance teams acting as mediators should consider a formal cost-benefit analysis exercise. Also sometimes called a benefit-cost analysis, this is a well-established process for guiding leaders to make decisions that are rooted in and informed by data on company goals and priorities and budget realities.

Account for Costs Accurately

If you’re relying on incomplete or inaccurate data to finish your cost-benefit analysis, the results of the analysis will follow suit. If the costs outweigh the benefits, ask yourself if there are alternatives to the proposal you haven’t considered.

Cost benefit analysis

By taking the sum of each user’s willingness to pay, Dupuit illustrated that the social benefit of the thing (bridge or road or canal) could be measured. Some users may be willing to pay nearly nothing, others much more, but the sum of these would shed light on the benefit of it. It should be reiterated that Dupuit was not suggesting that the government perfectly price-discriminate and charge each user exactly what they would pay. Rather, their willingness to pay provided a theoretical foundation on the societal worth or benefit of a project. Simply taking the sum of the materials and labor, in addition to the maintenance afterward, would give one the cost.

Here are some of the most common applications for a cost-benefit analysis in project management. CBA has been criticized in some disciplines as it relies on the Kaldor-Hicks criterion which does not take into account distributional issues. This means, that positive net-benefits are decisive, independent of who benefits and who loses when a certain policy or project is put into place.

F. John Reh is a business management expert, with more than 30 years of experience in the field. A writer and journalist over the past 17+ years, he has covered business management for The Balance. CBA has also attracted a high degree of criticism from both economists and noneconomists. Certainly, CBA has many weaknesses and there are many problems in applying it to the environment. However, CBA offers a formal and conceptually simple way of presenting the advantages and disadvantages of a policy or project option.

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. 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.

  • During the project scope development phase, key stakeholders should be identified, notified, and given a chance to provide their input along the process.

  • The sales price of any item includes many additional factors that will throw off your analysis if you include them, not the least of which is a profit margin.

Cost-benefit analysis is best suited to smaller to mid-sized projects that don’t take too long to complete. In these cases, the analysis can help decision-makers optimize the benefit-cost ratio of their projects. The present value of a project’s benefits and costs is calculated with the present value formula (PV).

A CBA can help you determine, among other things, the financial viability of a project if you need to hire additional staff, and how you want to prioritize investments so you can make an informed decision. Conducting a cost-benefit analysis will give you justification and evidence both for and against changing your routines and adopting new business practices that’ll improve production, team collaboration, or what have you.
