NPV discounts all future cash flows of a project to today and subtracts the upfront cost. A positive NPV means the project earns more than the required rate of return and should be accepted; a negative NPV means it destroys value.
Formula
NPV = Σ [Cash Flowₜ ÷ (1 + r)ᵗ] − Initial Investment
Example
A project costing ₹1,000 that returns ₹1,200 in present-value terms has an NPV of +₹200 and is worth doing.
