ROI, or return on investment, is a key indicator for measuring the profitability of an investment, whether it is a marketing campaign, a business project or any other type of expense. It helps answer the essential question: « How much will this earn me? »
Calculating ROI is simple and effective. For example, if you invest 1,000 euros in a marketing campaign and generate 3,000 euros in revenue, ROI is calculated as follows: [(3,000 - 1,000) / 1,000] x 100 = 200%. This means that every euro invested earns two euros.
Understanding ROI is essential to optimize your investments and make informed decisions. In the following sections, we will dive deeper into its definition, its calculation and the factors to consider in order to maximize your returns.
What is ROI or return on investment?
The importance of ROI in business management
ROI, or return on investment, is an essential financial indicator in business management. It makes it possible to assess the performance of investments and helps companies make informed decisions.
A positive ROI indicates that the investment is profitable, while a negative ROI shows that the revenue generated does not cover the costs incurred.
The main value of ROI lies in its ability to compare the profitability of different investments. This helps companies prioritize the projects and campaigns that offer the best returns, thereby optimizing the use of resources.
For example, in the case of several simultaneous marketing campaigns, ROI makes it possible to identify the one that generates the most revenue relative to the costs invested. This makes it easier to focus efforts and resources on the best performing campaigns.
Applications of ROI
ROI has applications in various areas of business management, including marketing, investment projects and financial management.
In marketing, it is used to assess the effectiveness of advertising campaigns and communication strategies. For example, a company that launches a campaign on Google Ads can use ROI to measure whether the advertising spend generates enough sales to justify the costs.
In the context of investment projects, ROI makes it possible to estimate the potential profitability before making a decision. This analysis includes the initial costs, the expected revenue and the associated risks, thereby providing a solid basis for informed choices.
Accountants and financial managers frequently rely on ROI to advise companies on the best investment opportunities and to optimize their investment portfolio.
Calculating return on investment to assess the profitability of an investment
The ROI calculation formula
Return on investment (ROI) is calculated easily thanks to a simple formula. To obtain ROI, you need to know the cost of the investment as well as the benefits it generates.
The formula is as follows:
ROI = ((Investment gain - Investment cost) / Investment cost) × 100
Or, in a simplified form:
ROI = (Benefits generated / Investment cost) × 100
This formula expresses ROI as a percentage, which makes it easier to compare different investments.
Examples of ROI calculation
Here are a few practical examples to better understand how ROI is calculated:
Example 1: marketing investment
Suppose you invest 10,000 euros in a marketing campaign and that this campaign generates 15,000 euros in revenue. The ROI calculation would be:
ROI = ((15,000 - 10,000) / 10,000) × 100 = 50%
This result means that for every euro invested, you earned 0.50 euro in return.
Example 2: real estate investment
Imagine you buy an apartment for 200,000 euros and you generate 10,000 euros in net rent per year. If, after one year, the value of the apartment rises to 250,000 euros, the ROI calculation takes into account the rent and the appreciation of the property:
ROI = ((10,000 + (250,000 - 200,000)) / 200,000) × 100 = 30%
This result includes the net rent as well as the capital gain on the property.

Interpreting the results
Interpreting ROI is essential to assess the profitability of an investment. A positive ROI indicates profitability, while a negative ROI reveals losses.
Here are a few important points to keep in mind:
Positive ROI: a positive ROI shows that the investment generated benefits greater than the costs incurred. For example, a ROI of 20% means that for every euro invested, you earned 0.20 euro in return.
Negative ROI: a negative ROI indicates that the revenue generated by the investment is not enough to cover the costs. This means that the investment is at a loss. In this case, it is important to review the strategies and the associated costs.
Comparing investments: ROI makes it possible to compare the profitability of several investments. This helps companies prioritize the projects and campaigns that offer the best returns, thereby optimizing the allocation of resources.
Limitations and critical considerations regarding ROI
Limitations of using ROI
Despite its simplicity and usefulness, ROI has several limitations that are essential to take into account when using it. One of the main limitations lies in the failure to account for the time dimension of the investment.
ROI offers a static view of profitability at a specific moment, without integrating future cash flows or the future value of the investment.
Another important limitation is the disregard for the risks associated with the investment. For example, in the context of a real estate investment, ROI does not consider risks such as rental vacancies or market fluctuations.
As a result, two investments showing identical ROIs may present very different risk profiles.
In addition, ROI can be influenced by the assumptions used for its calculation. Estimates of revenue, operating expenses and the future valuation of the asset can vary significantly, which impacts the accuracy of the ROI.
It is therefore important to consider several scenarios and not to rely solely on a single assumption.
Finally, ROI does not take into account long-term benefits or strategic advantages that are not directly measurable in financial terms. Elements such as brand recognition or customer loyalty can be decisive for the long-term health of the company, but they are not reflected in the ROI calculation.
Complements to ROI in financial analysis
To address the limitations of ROI, it is often necessary to complement it with other financial indicators. Net present value (NPV) and the internal rate of return (IRR) are tools that take into account future cash flows as well as the time value of money. These metrics make it possible to assess the profitability of an investment over the long term while considering future risks and opportunities.
Social return on investment (SROI) is another relevant indicator, integrating the social and environmental dimensions of investments. This type of ROI includes ESG (Environmental and Social Governance) criteria and SRI (socially responsible investment) practices, thereby offering a more comprehensive view of the impact of an investment.
Finally, it is essential to monitor ROI regularly and to adjust it based on indirect costs as well as changes in market conditions. This may include the use of tables and analysis software to visualize the data, thereby enabling more informed and accurate decision-making.

FAQ
What is the basic formula for calculating return on investment (ROI)?
The basic formula for calculating return on investment (ROI) is as follows:
ROI = (Investment gain - Investment cost) / Investment cost × 100
This formula makes it possible to assess the ratio between the cost of the investment and its gains, expressed as a percentage.
What are the main factors to consider when measuring the ROI of an investment, particularly in the context of a Source-to-Pay solution?
To measure the ROI (return on investment) of an investment, particularly in the context of a Source-to-Pay solution, several key factors must be taken into account:
- Capital invested: the initial amount invested in the solution.
- Periodic revenue: the savings or benefits generated by the solution, such as the reduction of process costs or the increase in efficiency.
- Final value of the investment: the total value of the solution at the end of the investment period, including any appreciation or depreciation.
- Total costs: all the costs associated with implementing and maintaining the solution, including license, training and support fees.
- Taxes and tax deductions: the taxes paid and the tax deductions applicable to the investment.
- Investment duration: the period during which the solution was used.
How can ROI be influenced by the investment duration and the associated risks?
ROI can be significantly influenced by the investment duration and the associated risks:
- Investment duration: the duration affects the comparability of ROIs. The same ROI obtained over different periods should not be assessed in the same way. In general, a shorter investment with the same ROI is often preferred.
- Associated risks: risks play an important role. A high ROI may indicate a high level of risk. A less risky project, even with a slightly lower ROI, can be more attractive in terms of stability and financial security.
What are the different types of ROI (for example, gross ROI, net ROI, cash ROI) and which situations are they best suited to?
Here are the main types of ROI and their uses:
- Gross ROI: assesses the profitability of an investment without taking the costs into account. It is useful for estimating the profitability potential of a project before considering the expenses.
- Net ROI: takes into account the revenue and the costs, offering a more accurate analysis of the profitability of an investment.
- Cash ROI: measures the cash flows generated by an investment. This type of ROI is particularly useful for long-term investments or those generating cash flows over an extended period.
These different types of ROI are suited to varied contexts, such as assessing the profitability of marketing campaigns, technology projects or investments in human resources.
