NPV / IRR Calculator
Analyze Net Present Value (NPV), calculate Internal Rate of Return (IRR / MIRR), map project profitability indexes, and view real inflation-adjusted curves.

Investment Periodic Cash Flows
Enter one cash flow amount per line. Period 0 represents initial capital (usually negative). Subsequent rows denote periodic gains or losses.

PI Metrics: A Profitability Index greater than 1.0 indicates that the present value of future capital inflows exceeds the initial investment outlay.
Capital budgeting metrics: NPV, IRR, and MIRR
Net Present Value (NPV) discounts future cash flow elements to estimate present value margins. The index maps: NPV = Σ [CF_t / (1+r)^t].
Modified IRR (MIRR) resolves standard IRR pitfalls by assuming capital is financed at borrow rates and reinvested at reinvestment rate indexes.
