When Virtual Reality Is Worth the Investment: A Two-Layer Systematic Review of Global Research, Economic Evidence, and Cost–Value Decision Making
This two-layer systematic review reveals a critical disconnect between high global research output in virtual reality and the scarcity of robust economic evidence, demonstrating that while VR often reduces specific operational costs or improves outcomes, it rarely lowers total first-use costs and requires a structured decision framework to justify investment, particularly given the notable absence of direct economic evaluations for major research-producing nations like China, Japan, and South Korea.

Virtual reality has long promised to transform how we learn, heal, and work, offering a way to practice dangerous skills or explore distant places without leaving a room. But for the hospitals, factories, and governments considering the purchase of this technology, a simple promise is not enough. They need to know if the investment makes financial sense. The core question is not whether the technology works, but whether it saves money or provides better value than the traditional methods it replaces. This requires looking past the excitement of the headset itself to examine the actual ledger: the cost of the equipment, the time spent training staff, the price of the software, and what is actually saved by using it. Sometimes, a new tool costs more upfront but saves money over time by reducing the need for expensive materials or travel. Other times, it might be cheaper to stick with the old way. Determining which is which requires a careful accounting of every dollar and hour involved.
A recent comprehensive review by Elena Popescu from the University of Oradea tackles this exact problem by separating the sheer volume of research from the actual economic proof. The study operates on two distinct levels. The first level acts as a global census, counting how many scientific papers have been written about virtual reality and identifying which countries are writing them. The second, more rigorous level digs into those papers to find only the ones that actually calculate costs, savings, or financial value. This two-step approach reveals a striking disconnect: a country can be a massive producer of research papers while having almost no evidence that the technology saves money in its own hospitals or industries.
The census part of the study examined over 85,000 English-language research papers published between 2006 and September 2026. The United States emerged as the largest producer of this research, followed closely by China, the United Kingdom, Germany, Italy, South Korea, and Canada. However, the type of work these nations produce varies significantly. The United States and the United Kingdom focus heavily on healthcare and surgical training, while China concentrates on engineering, construction, and industrial applications. Despite this massive global output, the review found that very few of these studies actually answer the question of whether virtual reality is worth the money. When the researchers filtered the thousands of papers down to only those that contained specific economic data, the number shrank dramatically. Out of the initial pool, only 49 studies met the strict criteria for a proper economic evaluation.
The findings from these 49 studies paint a nuanced picture where virtual reality rarely reduces the total cost of a project on its first use. Instead, the technology often becomes cheaper only after it is used many times, spreading the high initial price of the equipment and software over a large number of trainees. In many cases, virtual reality does not make the entire process cheaper; rather, it reduces specific costs, such as the time instructors spend in a live drill, the consumption of expensive laboratory materials, or the need for travel. For example, in surgical training, virtual reality can save money by allowing students to practice repeatedly without using expensive cadavers or operating room time, but the savings only appear after the initial investment is paid off through reuse. In other scenarios, such as rehabilitation, the technology might be more effective at improving patient outcomes but also more expensive than simple home exercises, meaning a decision-maker must choose whether the extra benefit is worth the extra cost.
The review also highlighted significant gaps in the global evidence. Despite China being the second-largest producer of research papers, the review found no eligible primary economic studies from mainland China, Japan, South Korea, France, or Italy that met the strict criteria. This does not mean such studies do not exist, but it indicates that they were not found in the English-language sources or specific searches conducted for this review. The United States and the United Kingdom provided the bulk of the usable economic data, with the UK contributing several studies that showed virtual reality was not always cheaper than traditional methods. One study found that a home exercise program was both cheaper and just as effective as a virtual reality console program for arm rehabilitation, suggesting that the high-tech solution is not automatically the better financial choice.
To help institutions make better decisions, the author proposes a new framework for evaluating these investments. This approach insists that before buying the technology, an organization must clearly define what specific cost they hope to reduce, such as instructor time or travel expenses, and compare it directly against the traditional method. They must also calculate the initial setup costs, the ongoing maintenance fees, and the number of people who will use the system. The review concludes that there is no universal rule stating that virtual reality is a good investment. It is only worth the money in specific situations where the alternative is very expensive, dangerous, or impossible to repeat often enough. For many other applications, the technology may offer better learning or health outcomes, but it will likely come with a higher price tag, requiring a conscious decision to pay more for that extra value.
