Return on investment or ROI is a profitability ratio that computes the benefits of an investment for a proportion of their initial price. To put it differently, it measures just how a lot of cash was made about the investment for a proportion of their buy cost. It shows traders how effectively each dollar spent in a job is at generating a benefit. Investors not just utilize this ratio to quantify how well an investment done, in addition they use it in order to evaluate the performance of various investments of all sorts and dimensions.

For instance, an investment in share could be in comparison to one in gear. It doesn’t matter what the type of investment because the return on investment calculation only looks that the benefits and the costs associated with the investment.

That being said, the ROI calculation is one of the most common investment ratios because it’s simple and extremely versatile. Managers can use it to compare performance rates on capital equipment purchases while investors can calculate what share purchases performed better.

## Formula

The return on investment formula is calculated by subtracting the cost from the total income and dividing it by the total cost.

As you can see, the ROI formula is very simplistic and broadly defined. What I mean by that is the income and costs are not clearly specified. Total costs and total revenues can mean different things to different individuals. For example, a manager might use the net sales and cost of goods sold as the revenues and expenses in the equation, whereas an investor might look more globally at the equation and use gross sales and all expenses incurred to produce or sell the product including operating and non-operating costs.

In this way, the ROI calculation is very versatile, but it can also be very manipulative depending on what the user wants to measure or show. It’s important to realize that there is no one standardized equation for return on investment. Instead, we’ll look at the basic idea of recognizing benefits as a percentage of income. To truly understand the return on an investment presented to you, you have to understand what revenues and costs are being used in the calculation.

## Example

Now that you know that there isn’t a typical equation, allow’s consider a simple model without getting into price and sales sections. Let’s look in Keith’s Brokerage House for instance. Keith is a stockbroker that specializes in penny assets. Keith created a somewhat risky investment at a liquid metals share a year ago after he bought 5,000 stocks at $1 per share. Nowadays, a year after, the fair store value of each share is $3.50. Keith sells the share and utilizes an ROI calculator to quantify his performance.

As you can see, Keith’s return on investment will be 2.5 roughly 250 percent. This usually means that Keith earned $2.50 for each dollar he spent in the liquid metals firm. This investment has been extremely efficient since it gained 2.5 times.

We could compare Keith’s great selection of liquid metals along with his other fiscal selection of investing at a medical equipment business. He bought 1,000 stocks at $1 a share and sold for about $ 1.25 per share.
