How to Use This Calculator

Enter the total dining seats and the average turns per meal period.
Set the number of meal periods per day (e.g., 2 = lunch and dinner).
Enter the peak hour percentage -- the share of daily covers served in the busiest hour (30-50% is typical).
Review the peak racks/hour needed to identify the correct machine type (under-counter, door-type, or conveyor).
Use the daily water usage and energy estimates to evaluate operating costs.
