About the NPV (Net Present Value) Calculator

Net present value (NPV) discounts a series of future cash flows back to today's dollars and subtracts the upfront investment, showing whether a project is expected to create or destroy value.

Formula: NPV = ∑ [Cash Flowt ÷ (1 + r)t] − Initial Investment, summed over each year t.

A positive NPV means the investment is expected to earn more than the discount rate (your required return); a negative NPV means it falls short and would destroy value at that rate.
