Return on Investment (ROI)
An ROI measures what you gain instead of what you have paid out. This is not necessarily a purely financial term, but what is gained vs. what is lost must be goods, items, services, or something else that is quantifiable and comparable to one another to achieve an accurate ROI and determine how successful the investment ultimately was.
The ROI calculation is as follows: (Benefit-Cost)/Cost = ROI
Accurately calculating your ROI is crucial to determining the true profitability of an investment and as a comparison tool between investments for forecasting or risk analysis.

A basic four-function calculator used to be monstrously expensive. Now it comes built into every thirty-dollar smartphone, along with smartphone.
