Drone adoption has grown consistently since 2010, with the most rapid expansion occurring in the Southwest. As of 2025, Federal Aviation Administration (FAA) registration data[1] indicate that Texas leads the nation with more than 600 registered agricultural drones, followed by California with over 500 units, while New Jersey has approximately 50, reflecting both regional cropping patterns and technology diffusion.
This study focuses exclusively on applicator drones, where costs and benefits are more directly tied to operational efficiency and field-level outcomes. While scouting drones also hold promise, evaluating their economic value is complicated by the highly variable costs of data processing and analysis, which depend heavily on farm management capacity and service arrangements.
Existing economic evidence, largely from China, suggests benefits from drone spraying, including increases in farm revenue of $176-$198 per acre (Quan et al., 2023), decreases in pesticide expenditures by $66 per acre (Li et al., 2025), for large-scale rice producers. Recent reviews further emphasize the potential of aerial spraying applications, especially in orchard systems, despite ongoing technical and regulatory challenges (Calderone et al., 2025). Although drone technology holds considerable potential, the question of whether owning an applicator drone represents a financially viable decision for producers remains a critical issue.
This study evaluates drone investment decisions from a farm management perspective, with the objective of identifying the economic and operational conditions under which drone adoption can enhance farm profitability. The primary analysis compares the relative costs and benefits of on-farm drone application with those of custom-hired spraying services. Both fixed investment costs and ongoing operating costs of drone use, including labor time and fuel required for battery charging, are incorporated into the analysis.
Drone specifications determine the time and fuel required for application operations. Higher coverage rates and longer flight (hovering) times reduce total application time, while lower generator fuel consumption rates decrease operating fuel costs. Larger battery capacities and faster charging times further improve operational efficiency by reducing the number of batteries required to sustain continuous field application. Additional assumptions regarding operational conditions and drone specifications are summarized in Table 1.
Figure 1 presents the net present value (NPV) of the investment over time. Under the assumed lifespan, batteries are replaced in year 5 and the drone is replaced in year 10. Greater application intensity increases cost savings relative to custom hiring. Under the baseline parameter assumptions, total annual applications must exceed 20 for the investment to achieve a positive NPV and pay off before year 6.

Figure 1: NPV over time for 30ac field, across number of applications
Drone investment becomes more economically favorable as field size increases (Figure 2). Assuming 30 applications per year, a minimum of 30 acres is required to reach the break-even point before year 6, while a 35-acre operation achieves break-even before year 4.
Drone application can affect farm revenue through multiple channels. Timely applications may increase crop yield or improve quality, while more targeted spraying can reduce input costs. However, technical inefficiencies may lead to ineffective applications that reduce revenue. The sensitivity analysis below examines how changes in revenue per acre and field size influence investment outcomes, assuming 20 applications per year. The baseline scenario assumes a 30 acre field with no revenue change, for which the investment breaks even in year 6. When revenue increases by more than $40 per acre, positive NPV can be achieved on fields as small as 25 acres. In contrast, on a 35 acre field, even a revenue loss of $40 per acre yields NPV outcomes similar to the baseline case, indicating break-even at approximately year 6.
