There are provided systems and methods for communication device input interfaces for use in determining a true cost of an item with associated purchases. A user may utilize a communication device, such as a mobile phone or wearable computing device, to input information identifying an item. The input may be an image, audio, or text input. The input may be communicated to a server that determines associated purchases required or recommended with the item identified by the user. For example, the user may be recommended to purchase additional items for the installation of the item or for repairs to a home, work, or vehicle when using the item. The user may also be required to purchase shipping, labor, or other additional costs. The additional purchases may be determined from user and merchant information. A total cost for the item and the additional purchases may be determined for the user.
