Cash Flow Summary
| Period | Cash Flow | PV at IRR |
|---|---|---|
| Year 0 (Initial Investment) | -10,000 | -10,000 |
| Year 1 | +3,000 | +2,611.08 |
| Year 2 | +4,000 | +3,030.1 |
| Year 3 | +4,000 | +2,637.28 |
| Year 4 | +3,000 | +1,721.54 |
| Total | +4,000 | ≈ 0 at IRR |
IRR is calculated using Newton-Raphson iteration. A positive NPV at your hurdle rate means the investment clears your minimum required return. IRR assumes cash flows are reinvested at the IRR rate itself.
