Return on Investment (ROI) Definition
Return on investment (ROI) is a profitability ratio used for measuring the amount of profit generated by an investment relative to its cost. It evaluates the cost efficiency of an investment and is expressed as a percentage or ratio. It is calculated as the return of an investment divided by the cost of the investment. The formula for computing the ROI is, ROI = (Gain from Investment - Cost of Investment) / Cost of Investment For example, if an individual invests $1000 for buying the stocks of a company and then after a year, he or she sells the share at $1500 then profit from that investment is ($1500-$1000) =$500 and the return on investment is $500/$1000=0.5 or 50%
A Little More on What is Return on Investment
ROI is used for comparing returns from various investments that allow the investor to invest their capital efficiently. It is the most common indicator used across different types of investments. It is easy to calculate the ROI because of its simplistic nature; although, for companies it is a bit more complicated when there are several inputs. The investors compare the ROI of different investments and it is always better to go for a higher ROI. Negative ROI depicts a loss, so those investments should be avoided. ROI allows the investors to make an informed decision when investing their money. It is important for investors to use the same inputs for calculating ROI while comparing different investments. One shortcoming of comparing ROIs of similar project is it doesnt take time into consideration. Suppose, an individual invests $2,000 to buy stocks of a company. One year later he sells it at $2400. The profit from the investment is ($2,400-$2000) = $400 and ROI is $400/$2000= 0.2 or 20%. Then the same individual buys stocks of a company with $4000 and sells those shares in the market 3 years later at $4800. His profit from the investment is ($4800-$4000) = $800 and the return on investment is $800/$4000=0.2 or 20%. So apparently the ROI is the same for both the investments, but in the first case it took only one year and in the second instance it took three years. So, the first investment is more profitable than the second one although the ROI is the same for both. Thus, ROI provides a simplistic estimate of the profitability of an investment. As such, other indicators must also be taken into account when comparing different investments. The Rate of Return or Net Present Value can be used along with ROI to get a more accurate estimate.

Expatriate return on investment in the Asia Pacific: An empirical study of individual ROI versus corporate ROI, McNulty, Y., De Cieri, H., & Hutchings, K. (2013). Journal of World Business,48(2), 209-221. This paper presents return on investment (ROI) as a critical aspect of expatriate management and majors mostly on the organizational perspective of this phenomenon. It uses interviews with 31 long-term expatriates in 10 Asian countries to examine the extent to which individual ROI influences corporate ROI. It also investigates the challenges and opportunities to individuals and organizations alike that arise from expatriation in the Asia Pacific. Measuringreturn on investment(ROI) of organizations' internal communication efforts, Meng, J., & Berger, B. K. (2012). Journal of Communication Management,16(4), 332-354. This study investigates how the senior communication executives compute the effectiveness of the internal communication efforts of organizations and link them with business performance. The results suggest that a majority of the business communicators and organizations realized the importance of measuring internal communication initiatives. However, the study uses limited metrics in the assessment process. Thereturn-on-investment(ROI) process: Issues and trends, Phillips, J. J. (1998)...Educational Technology,38(4), 7-14. This article takes a rational approach to ROI and implements a relevant mix of evaluation strategies after understanding the drivers for the ROI process and its inherent weaknesses and advantages. It also explores its use in education and training. It also investigates the various perspectives of individuals towards ROI where some regard is as very flawed and inappropriate while others regard it as the answer to accountability. A new model for measuringreturn on investment(ROI) for safety programs in aviation: an example from airline maintenance resource management (MRM), Taylor, J. C. (2000) (No. 2000-01-2090). SAE Technical Paper. This paper develops a new ROI model to compare and evaluate the new and quickly evolving aviation maintenance resource management (MRM) programs. This model is easy to understand and apply and is essential since it will allow airline maintenance employees to identify the financial advantages of these safety initiatives and therefore plan accordingly. What's the return on ROI? The benefits and challenges of calculating your library's return on investment, Matthews, J. R. (2011). Library Leadership & Management,25(1). This study details how various libraries have tried to improve the discussion of the value of the public library by preparing a return on investment (ROI) analysis. This ROI is used in the estimation and the comparison of the costs and benefits of a particular undertaking. ROI calculates the total value of the public library to the residents of a community by summing up the use and non-use benefits. The effect of return on equity (ROE) andreturn on investment(ROI) on trading volume, Ichsani, S., & Suhardi, A. R. (2015).Procedia-Social and Behavioral Sciences,211, 896-902. This paper presents Return on Equity (ROE) and ROI as indicators in profitability ratio. This is because these two utilize net income as a benchmark when measuring profitability. ROI and ROE also affect the volume of trade but give weak results. However, the paper also states that the investors don't only look at the profitability factor which is presented by the ROE and ROI.

Return on investment(ROI), Sandborn, P. (2013). InCost Analysis of Electronic Systems(pp. 329-348). This paper explains that forming an ROI is accompanied by investing money in a financial instrument but that calculating ROI involves the generation of an increase in the customer base, cost savings or future cost avoidance and this is not easy to do.
