Net Present Value (NPV)

Net present value (NPV) is the sum of all future cash flows from an investment, discounted back to today's value. A positive NPV means the investment creates value; negative NPV means it destroys value.

Formula
NPV = Σ [Cₜ / (1 + r)ᵗ] − C₀

NPV uses the time value of money to compare investments on equal footing. A return of $1,000 in 10 years is worth less than $1,000 today — NPV quantifies exactly how much less at a given discount rate.

Formula: NPV = Σ [Cₜ / (1+r)ᵗ] − C₀, where Cₜ is the cash flow in period t, r is the discount rate, and C₀ is the initial investment. Used extensively in capital budgeting, real estate analysis, and any multi-year investment decision.
