Steps To Calculate Data Science ROI

Calculating the ROI of data science projects involves several steps. By following this structured approach, you can accurately assess the value generated by your data science initiatives.

1. Clarify the goals and aims of the project

Begin by establishing specific, measurable goals for the data science project. These goals should align with broader business objectives to ensure the project contributes meaningfully to the organization’s overall strategy. 

It's essential to identify KPIs that will be used to track progress and measure the achievement of these goals. Precise alignment between the project’s objectives and the company’s strategic priorities will provide a solid foundation for evaluating ROI.

2. Calculate the expenses linked to the project

To understand the actual cost of a data science project, it's important to account for all related expenses. These typically include:

• Staff costs: Consider the salaries and benefits for all team members, including data scientists, analysts, technicians, project managers, and IT support staff.
• Software and applications: Factor in the costs of essential software tools, such as analytics platforms, AI frameworks, and presentation software for reporting and visualization.
• Technical infrastructure: Include expenses related to cloud computing services, data storage solutions, and hardware upgrades. Additionally, consider the costs of acquiring and organizing the data needed for the project.
• Training and skill development: Account for any training and professional development investments to equip team members with the skills required for the project.

3. Evaluate the project's gains

Next, assess both the tangible and intangible benefits of the project:

• Tangible financial benefits: Calculate the direct financial gains, such as increased revenue, cost reductions, and time savings. Time savings should be quantified by converting the hours saved into monetary value based on employee salaries or operational efficiencies.
• Intangible benefits: Consider the less quantifiable but equally important benefits such as improved customer satisfaction, enhanced brand reputation, and reduced risks. These factors contribute to the project's overall value, even if they are harder to express in dollar terms.

Gathering data on the identified KPIs before and after the project’s implementation is essential. This allows for a comparison that highlights the project's impact.

4. Calculate the ROI

After identifying the project’s costs and evaluating its gains, the final step is calculating the ROI. This step involves quantifying the overall financial performance of the data science project in terms of its costs.

The ROI formula is:

Data Science ROI = (Net Benefit from Data Science Project / Total Cost of Data Science Project) x 100

Where:

• The net benefit from the data science project is the total gains (both tangible and intangible) minus any ongoing operational costs. This includes revenue increases, cost savings, time efficiencies converted into monetary terms, and other measurable benefits.
• The total cost of the data science project is the sum of all expenses incurred, including staff costs, software and infrastructure investments, data acquisition, and training expenses.

Steps to calculate:

1. Determine the net benefit: Subtract the ongoing operational costs from the total gains (both financial and intangible) identified in step 3.
2. Sum up the total costs: Add up all the costs associated with the project as detailed in step 2.
3. Apply the ROI formula: Plug the net benefit and total cost figures into the formula to calculate the ROI percentage.

Example calculation:

Let’s say a data science project resulted in total measurable benefits of $500,000, as seen in the example offered in the previous section, and the total project cost was $200,000. After accounting for $50,000 in ongoing operational costs, the net benefit would be $450,000.

So, the ROI would be:

ROI = (450,000 / 200,000) * 100 = 225%

This result indicates that for every dollar spent on the project, the company gained $2.25 in return.

Interpret the results:

A positive ROI indicates that the project has delivered more value than its cost, justifying the investment. A higher ROI percentage means greater returns relative to the costs. Conversely, a negative ROI suggests the project's costs outweigh its benefits, signaling a need to reassess its approach or implementation.

5. Understand and share results

Evaluate the ROI against industry standards and company goals. Prepare a clear report detailing the ROI calculation, methodology, and critical insights. Communicate the results to stakeholders, highlighting the project's impact on business objectives.

6. Monitor

Regularly review the project's ROI to ensure it meets expectations. Identify areas for improvement and apply these lessons to enhance future data science projects, ensuring ongoing efficiency and value.

Successfully calculating the ROI involves several important steps.
