$/GPM is the price divided by the hot water flow the heater delivers at a 45 °F temperature rise, worked out from its kW rating. "Box GPM" is the maker's own maximum, often quoted at a much smaller rise, so it is shown but not ranked on. Your rise depends on your incoming water: the sizing calculator works it out from your ZIP.
