Abstract: Fiber project evaluation tools and related methods, graphical user interfaces (GUIs), and computer-readable media to provide and display cost estimates for a plurality of fiber solutions options that can be employed to deploy a fiber optic network for a fiber project are disclosed. Inputs are provided to allow a user to provide cost-related inputs to customize the cost estimates determined and displayed for the fiber solutions. In this manner, cost estimates can be provided for a variety of fiber solutions at the same time efficiently and visually in a GUI for efficient comparison purposes and to assist in making a choice on a fiber solution for a given fiber project. The cost estimates for the fiber solutions can also be generated and dynamically updated based on providing cost-related inputs to a user that affect the cost estimates for the fiber solutions in an iterative manner.
