The San Francisco Travel Association adopted DMAI's Event Impact Calculator in 2013 to better estimate the economic impact of events on the local economy. The tool calculates estimates spending in categories like lodging, food, and retail based on event details. It also estimates tax revenue and jobs supported. The Association uses the tool to demonstrate event value to stakeholders and identify events that generate more room nights than contracted blocks. It collects data on attendees to inform the tool's inputs. The tool's reports help educate partners on events' tourism contributions.
