The profit potential of self-service phone case vending machines is significant. A single machine in an ideal location can generate a monthly net profit of approximately $3,500, thanks to its low costs, high demand, and no-staff operation advantages.

The gross margin for phone cases typically ranges between 30% and 50%. Brand premiums and design elements can further enhance profit margins, but intensifying competition may cause profits to decline to 8–15%.

Selecting the right location is crucial, such as high-traffic areas like shopping malls or industrial zones, which can significantly boost sales. For example, selling 30 phone cases daily can generate approximately 300 yuan in profit, with monthly profits stabilizing around 10,000 yuan.

The global phone case market continues to grow, with projections reaching 28.5 billion USD by 2025, at an annual growth rate of 5.8%, presenting a vast business opportunity for self-service vending machines.
