Cost-benefit analysis (CBA) is a process used to measure the costs and benefits of a decision before taking action. It is a way of evaluating economic projects and different options to determine what is most financially viable. CBA is often used to determine the efficiency of a certain project by comparing the overall costs with total expected benefit or return.

To measure the effectiveness of a project or investment, the costs associated with the project must be evaluated along with the potential of earning that back in revenue. CBA affords an organization the ability to analyze a project using financial metrics to determine whether it is worth undertaking. If a cost-benefit balance is found, the process allows for individuals or organizations to make informed decisions about how to best invest their money.

When undertaking a CBA, tangible costs and benefits should be listed and then weighed up against each other. All material costs, including labour, materials and future investments, should be weighed against expected operational savings or potential revenues generated by the project. However, intangible benefits and costs can also be taken into account, such as employees’ morale, customer satisfaction and public perception. It is also possible to weigh up multiple options using sensitivity analysis, discounting of cashflows or what-if scenario analysis.

Ultimately, if the cost-benefit analysis shows that there are greater benefits than costs, it is generally seen as a favorable undertaking. It is often used in marketing, engineering and other processes by corporations and organizations, as a way of estimating potential outcomes. However, conducting a CBA can be costly in itself, which needs to be taken into account when considering the process. In addition, those conducting the CBA need to be certain that all scenarios, costs and benefits are taken into account, as miscalculation may lead to flawed decisions.

In conclusion, by understanding the process and its intricacies, a cost-benefit analysis can be used to provide insight and make informed decisions. For businesses, CBA can be used as a tool to better manage finances and lead to more profitable investments.
