fin.invest-npv Calculator
Calculates the Net Present Value (NPV) of a series of future cash flows discounted at a chosen rate to determine whether a project adds value. A positive NPV means the investment earns more than the discount rate — the fundamental rule of capital budgeting.
Inputs
Rate
Rate used to bring future cash flows back to today's value. Higher rates make future money worth less — used in NPV, bond pricing, and valuation.
Cashflow
Total net cash received or paid in one year. Used in payback period and simple ROI calculations.
Years
Reference formula or conversion factor shown for context.
Initial
Upfront cost — the negative cash flow at time zero in NPV/IRR analysis.
Results
PV of cash flows
Present value of all future cash flows, discounted at the required rate of return. The foundation of DCF (discounted cash flow) valuation.
NPV
Sample size or count used in the calculation.
decision
Sample size or count used in the calculation.
payback factor
A dimensionless multiplier applied in the calculation.
