Cost-Benefit Analysis of Computer Purchase for Small Business
This paper applies cost-benefit analysis to evaluate a computer purchase decision for a small independent business. The analysis identifies all relevant costs, including hardware, software, support, and installation ($1,452.28), and quantifies benefits from e-commerce expansion, increased traditional sales, and labor time savings across a three-year period ($3,443.58). The paper then applies net present value methodology with a 5% discount rate to account for the time value of money, yielding a net present value of $1,809.84. The conclusion supports the investment as financially justified, provided sales projections prove accurate.

What makes this paper effective
- Provides a concrete, real-world case study with specific dollar figures and itemized costs, making the analysis tangible and easy to follow.
- Progresses logically from simple cost-benefit comparison to the more sophisticated net present value method, showing how financial analysis can be layered and improved.
- Acknowledges limitations and assumptions (e.g., the 5% discount rate is speculative) rather than presenting results as certainties, demonstrating analytical maturity.
- Uses clear tables to organize complex financial data, enhancing readability and allowing readers to verify calculations.
Key academic technique demonstrated
The paper demonstrates financial appraisal through progressive complexity. It begins with straightforward subtraction (benefits minus costs), then introduces the net present value framework—a standard investment evaluation tool in finance and business. By showing both methods and explaining why NPV is superior (accounts for time value of money), the paper illustrates how practitioners move beyond naive approaches to more rigorous decision-making. The explicit discussion of discount rate selection and sensitivity (noting that results are "speculative") shows critical thinking about model assumptions.
Structure breakdown
The paper follows a formal financial analysis structure: (1) problem statement and context, (2) itemized cost inventory with total, (3) benefit estimation across three years with multiple benefit streams, (4) initial net calculation, (5) refined NPV calculation with discounting, and (6) conclusion. This mirrors standard business case analysis and investment recommendation formats. Each section builds on prior data, and tables serve as both evidence and reference points for subsequent calculations.
Introduction
In today's commercial environment, it is necessary that small as well as large businesses remain competitive. For every investment there will be an opportunity cost, so it is essential that potential investments are assessed to help maximize value creation. One approach frequently used is the cost-benefit approach, which measures costs and benefits based on the underlying principle that an investment or project should only proceed if the benefits are greater than the costs incurred. If a small business is considering investing in a computer, a cost-benefit analysis may help assess whether the investment is likely to be beneficial.
This analysis begins with the assessment of costs to be incurred and potential benefits. In this case, it is assumed that a business such as an independent shop is considering purchasing a computer to increase efficiency for counting and record-keeping, as well as to facilitate an expansion strategy into e-commerce, allowing the business to sell online.
Identifying and Calculating Costs
The computer selected as suitable for the small business is a Dell OptiPlex mini tower. It is essential that all requirements are considered, not just the cost of the core computer. All items assessed as required are taken from the Dell website. The computer is a starting point, but it is also necessary to look at the additional hardware, software, and support needed. For example, a computer system requires a monitor, speakers, and a printer. As the business will rely on a computer, it is also advisable to ensure there is sufficient technical support with a service agreement. The costs include an extended warranty for both the computer and printer, and accident insurance so that replacements can be made if needed. The software included is Microsoft Office, as well as a three-year Dell data protection and encryption license.

Quantifying Benefits Over Time
The next stage is to consider the benefits that will emerge as a result of the investment. The benefits will not be immediate but will accumulate over time. In this assessment, it is assumed that the computer will have a useful life of three years, after which it will need to be replaced. Therefore, the cost-benefit analysis is based on a three-year period. Since benefits accumulate over three years, the initial assessment is based on annual benefits.
There are several potential sources of benefit. First is the ability of the firm to undertake an e-commerce strategy, which will increase sales. The development of forecasts accounts for the way in which sales will be low in the first year and grow over time. The benefit from online sales is the net benefit to the firm, measured as the increase in net profit (sales less costs) expected to occur as a result of the new strategy facilitated by the computer. This figure also allows for the possibility that some traditional customers may move to the online sales medium.
In addition to e-commerce benefits, there may also be increases in traditional sales. With the firm's ability to establish a web presence through a webpage and social media presence, the firm can undertake cost-effective marketing to support gaining traditional customers who will visit the shop. The increase in net profit as a result of these sales is also included in the benefits.
The ability of the business owner to save time is a convenience, but it can be difficult to monetize. However, if a total of 2 hours are saved per week, this may result in the ability to reduce employee hours by 1 hour, which is a cost saved and can be included. It is assumed that 1 employee, at a total cost of $12 per hour, can be calculated as a benefit. It is assumed that wages will rise by 5 percent per annum. The net benefits for each of the three years are shown in Table 2.

Simple Cost-Benefit Assessment
This initial analysis would appear to indicate that there is a benefit to the purchase, as the benefits are greater than the costs. In this case, there is a net benefit of $1,991.30, as shown in Table 3.

Conclusion
Overall, it would appear that, as long as the increased profit projections are correct, this would be a wise investment and would produce benefits far greater than the costs. The net present value analysis, which appropriately accounts for the time value of money, still yields a positive return of $1,809.84, suggesting that the computer purchase is financially justified for the small business.
