Understanding the value of an investment is crucial in any business decision-making process. One effective way to do this is through a cost-benefit analysis. This method allows businesses to weigh the potential positive effects against the costs associated with a particular action or decision. In this guide, we will walk you through the steps of conducting a cost-benefit analysis and provide a detailed example for better understanding.how to do cots-benefit analysis

Part 1. How Do You Perform a Cost-Benefit Analysis?

A cost-benefit analysis (CBA) is a systematic process for evaluating the potential benefits and costs associated with a specific project or decision. The goal is to determine whether the benefits outweigh the costs and whether the project or decision is economically viable. Here's a step-by-step guide on how to conduct a cost-benefit analysis:

Step 1. Define the Project or Decision

Clearly define the scope and objectives of the project or decision. Identify what you are evaluating and what alternatives exist.

Step 2. Identify Costs and Benefits

Costs: These are the expenses associated with the project or decision. Include both direct and indirect costs. Examples include initial investment costs, operating costs, maintenance costs, and any other relevant expenses.

Benefits: These are the positive outcomes or gains resulting from the project or decision. Benefits can be tangible (monetary) or intangible (non-monetary), and they can be short-term or long-term.

Step 3. Quantify Costs and Benefits

Monetary Values: Assign monetary values to both costs and benefits. This step can be challenging for intangible benefits, but it's essential for a comprehensive analysis.

Time Frame: Determine the time frame over which costs and benefits will occur. Consider the time value of money by discounting future values to present values.

Step 4. Calculate Net Present Value (NPV)

Subtract the total costs from the total benefits to calculate the Net Present Value. NPV helps account for the time value of money. A positive NPV indicates that the benefits exceed the costs.cost-benefit analysis


  • Bt= Benefits in time period
  • Ct= Costs in time period
  • r = Discount rate
  • n = Time horizon

Step 5. Calculate Return on Investment (ROI)

Calculate the ROI as a percentage using the following formula:cost benefit analysis

A positive ROI indicates a profitable project.

Step 6. Sensitivity Analysis

Assess the impact of changes in key assumptions on the analysis. Identify the most sensitive variables and consider different scenarios.

Step 7. Decision Making

Based on the results of the analysis, make an informed decision. If the NPV is positive and the ROI is acceptable, the project is considered economically viable.

Part 2. Detailed Example for Cost-Benefit Analysis

Let's dive into a more detailed example of a cost-benefit analysis for a solar power installation project.

Solar Power Installation Project Cost-Benefit Analysis:

1. Project Definition:

Scope: Installing a solar power system to generate electricity for a business facility.

Objective: Reduce electricity costs and promote environmental sustainability.

2. Costs:

Initial Investment: $500,000 (includes solar panels, inverters, installation, etc.).

Operating and Maintenance Costs: $20,000 per year for routine inspections, cleaning, and minor repairs.

3. Benefits:

Annual Energy Cost Savings: $50,000 (estimated reduction in electricity bills).

Environmental Benefits: Reduction in carbon emissions. While it's challenging to assign a precise monetary value, it contributes to corporate social responsibility and may have long-term financial benefits.

4. Time Frame:

Analysis Period: 10 years (the estimated useful life of the solar power system).

5. Quantification of Costs and Benefits:

Discount Rate: 5% (reflects the opportunity cost of capital).

Monetary Values:

r=0.05 (discount rate)

6. Net Present Value (NPV) Calculation:

The NPV will be positive or negative based on this calculation.

7. Return on Investment (ROI) Calculation:

8. Sensitivity Analysis:

Assess the impact of changes in key variables (e.g., energy savings, discount rate) on NPV and ROI.

9. Decision Making:

If NPV is positive and ROI is acceptable, the solar power installation project is economically viable.


Hypothetical Results:

  • NPV: $100,000 (positive)
  • ROI: 20% (acceptable)

Decision: Proceed with the solar power installation project as the benefits outweigh the costs, and the return on investment is satisfactory.
