Firms typically have many ideas for projects and need to make informed decisions regarding which projects to take on. One way to decide which project(s) to move forward with is by calculating the discounted payback period, net present value, probability index, or internal rate of return.

In this post, a) propose a project for a Apple inc (new equipment, software upgrades, etc.) or personally (replacing windows in a house, adding solar panels, etc.), b) calculate either the discounted payback period, net present value, or probability index, and c) tell us whether you would take on the project and why. Remember to show the formula and numbers that went into your results.
