How it works
The internal rate of return is the annual return that sets the net present value of all cash flows to zero. It is the single rate that summarizes a project or investment - higher is better, and a project clears the bar when IRR exceeds your required return.
IRR solves: 0 = sum CFt / (1 + IRR)^t
