A scheduling system suitable for tracking and visually indicating impact of events on free time is provided. The scheduling system receives a request associated with an event. In response, the scheduling system accesses, from a data storage, user data structure for a user associated with the event, whereby the user data structure indicates scheduling information for the user including free time of the user. The scheduling system determines an impact on the free time of the user based on the user attending the event. The scheduling system then generates a user interface that includes a visual indication of the impact of attending the event on the free time of the user and causes presentation of the user interface on a client device of the user.
