Arcade operators measure the return on investment (ROI) for each machine using a combination of financial and operational metrics. Key methods include tracking revenue per play by counting coins, tokens, or digital payments, as well as analyzing daily/weekly earnings to identify peak performance periods. Operators also factor in maintenance costs, such as repairs and part replacements, to determine net profitability.

Player engagement metrics, like average session duration and repeat visits, help assess a machine's popularity. Additionally, operators compare location performance—placing machines in high-traffic areas often yields better returns. By combining these data points, arcade owners optimize their game lineup and maximize profitability. Advanced operators may use digital tracking systems to automate ROI calculations and adjust pricing or promotions dynamically.

Regularly reviewing these metrics ensures machines remain profitable and aligns with customer preferences, sustaining long-term arcade success.
