Present value (PV) is the current worth of a future sum of money, discounted at a specific rate of return. It answers: "How much would I need to invest today to have $X in Y years?" Formula: PV = FV / (1 + r)^n. A dollar today is worth more than a dollar tomorrow because of its earning potential — this is the core concept of the time value of money.
Net Present Value (NPV) is the sum of all discounted future cash flows minus the initial investment. A positive NPV means the investment generates more value than its cost at the given discount rate — it is worth pursuing. A negative NPV means the investment destroys value at the required rate of return. An NPV of zero means you earn exactly your required rate, breaking even in present-value terms.
The time value of money (TVM) is the principle that a dollar available today is worth more than a dollar in the future because it can be invested and earn returns. TVM is the foundation of all financial calculations including present value, future value, loan amortization, and retirement planning. The discount rate used in PV calculations represents the opportunity cost — what you could earn by investing elsewhere.
