# The ROI Formula: How to Calculate Returns on Investment

The ROI formula has become an indispensable tool for any business that wants to measure the success of its investments. ROI, or Return on Investment, is a financial metric that allows managers to measure the return they get from an investment. This metric can be used to evaluate any investment that a business makes, and can help managers make informed decisions about where to allocate resources.

Calculating ROI is relatively simple. The formula for calculating ROI is:

(Return – Investment) / Investment x 100

To use the formula, you need to know the amount of money you invested in a particular project, and the return you received from that investment. Typically, the return on investment is expressed as a percentage.

Let’s use an example to illustrate how the ROI formula works. Pretend we are investing in a new advertising campaign for our company. We spend \$10,000 on this campaign and it generates \$20,000 in new sales. To calculate the ROI for this investment we would use the ROI formula:

(\$20,000 – \$10,000) / \$10,000 x 100 = 100%

This means that we generated a return of 100% on our investment. For every dollar we invested in the advertising campaign, we received two dollars in new sales. This is a good return on investment and indicates that our advertising campaign was successful.

It is important to remember that ROI is not the same as profit. Profit is the amount of money you make from an investment, while ROI is the percentage return on your investment. A high ROI does not necessarily mean that you are making a large profit, just as a low ROI does not necessarily mean that the investment was unsuccessful.

There are some limitations to using the ROI formula as well. For example, it does not take into account the time value of money or the cost of borrowing. It also does not measure other non-financial factors such as customer satisfaction or brand perception.

Despite these limitations, ROI is a useful tool for managers and businesses to measure their returns on investment. By evaluating the ROI of various projects and initiatives, managers can make informed decisions about where to allocate resources and how to measure the success of their investment.
