Return on Investment (ROI) is a vital metric for evaluating investment effectiveness and profitability, enabling comparisons between different opportunities. It quantifies the return on the investment cost by dividing the benefit by the investment cost, expressed as a percentage or ratio. It assists investors in assessing performance and building a persuasive business case for proposed ventures.
In cases where enterprises have immediate goals, like securing market share or positioning for sale, ROI measurement can be tailored to align with these objectives. This approach goes beyond immediate profits or cost reductions, focusing on strategic objectives for long-term business success and value.
How to Calculate Return on Investment (ROI)
Return on Investment (ROI) enables a comparison between the earnings generated from your investment and the initial cost of that investment. The following are two formulas for calculating ROI:
Formula 1
ROI= [(Investment Value at Maturity – Invested Value)/Invested Value] × 100
Formula 2
ROI= (Net Gains/ Invested Value)×100
Where,
Net Gains= Final Value of Investment – Invested Value
ROI can take on positive, negative, or zero values and is consistently expressed as a percentage.
When Should You Use ROI?
You should consider using ROI in various situations where its calculation proves advantageous. It serves several purposes, including:
1. Assessing Investment Value
Whether you’ve invested in a single location or a network of businesses like a franchise, ROI helps determine the value of each investment. By considering the purchase price, annual net sales, and length of ownership, you can calculate ROI to evaluate margins, plan for business expansion, and enhance overall profitability.
2. Monitoring Marketing Effectiveness
ROI is a valuable tool for marketers to assess the success of their outreach efforts. Marketers can use ROI calculations to gauge the effectiveness of campaigns in attracting new customers. This approach also enables the evaluation of the sales team’s performance by analyzing the number of customers acquired for the products or services promoted within the allocated marketing budget.
3. Using Total Capital Employed for Earnings Rate Calculation
Total capital employed represents the assets available for investment in your company. These assets are crucial for increasing production and diversifying the range of products for sale. By factoring in the cost of additional assets or capital used to improve production, ROI can be calculated based on the increase in business sales resulting from these investments. This provides insights into the efficiency of capital utilization and the return on the total assets employed in the business.

What are the Limitations of ROI?
Return on Investment (ROI) is a widely used metric for assessing investment viability and profitability in business. Nonetheless, it has some drawbacks, including:
1. Temporal Oversight
ROI may not adequately consider the aspect of time in its evaluation. A higher ROI might seem favorable, but it may overlook the significance of time. For example, an investment with a higher ROI over a decade could be less advantageous than one with a slightly lower ROI but achieved within a single year.
2. Divergent Calculations
The lack of standardization in ROI calculations across businesses adds complexity. Since different methodologies are used, making cross-comparisons becomes challenging and, in some cases, meaningless.
3. Bias toward Higher ROIs
Managers may have a bias toward choosing investments with higher ROIs, potentially overlooking opportunities with lower ROIs that could still enhance a company’s value. This bias might lead to inefficient resource allocation.
4. Ignorance of Nonfinancial Gains
ROI calculations, especially for items like new computers, often focus solely on monetary aspects, neglecting nonfinancial benefits. For instance, quantifying the value of improved employee morale resulting from upgraded computers can be challenging within the traditional ROI framework.
