fin.internal-rate-of-return Calculator
Calculates IRR using the Newton-Raphson method from an initial investment and up to 10 years of cash flows. IRR assumes cash flows are reinvested at the IRR itself — when that's higher than the actual reinvestment rate, MIRR is the more accurate measure.
Inputs
Initial Invest
Upfront cost — the negative cash flow at time zero in NPV/IRR analysis.

Results
IRR
IRR (internal rate of return) -- the annualised return rate at which net present value equals zero. If IRR exceeds the hurdle rate, the investment adds value.
NPV at 10%
The value at the specified point or condition.
initial investment
The upfront capital deployed at time zero. This is the negative cash flow from which all future returns are measured.
total cash flows
The combined total across all inputs and components.

Newton-Raphson iteration
The proportional relationship between two quantities.
