The NPV profile is a graph that illustrates a project's NPV against various discount rates, with the NPV on the y-axis and the cost of capital on the x-axis. To begin, simply calculate a project's NPV using different cost-of-capital assumptions. Once these are calculated, plot the values on the graph.
Look Out! Since the IRR is the discount rate where the NPV of a project equals zero, the point where the NPV crosses the x-axis is also the project's IRR.
