Abstract: One example of determining an estimated time of arrival (ETA) based on calibrated distance includes a method implemented by a processor included in a mobile device to be carried by a user. An estimated distance between a starting location and an ending location is received. A calibration factor based on a location of the mobile device on the user's body and a movement pace of the user is determined. The estimated distance between the starting location and the ending location is modified based, in part, on the determined calibration factor resulting in a modified estimated distance. An estimated time to arrive (ETA) at the ending location is determined based, in part, on the modified estimated distance.
