• Screen whether projected inflows appear to exceed an upfront cost.

Quick FAQ

Is this financial advice?
No. NPV is a decision-support metric, not a complete investment recommendation.

How do I interpret NPV?
A positive NPV means the cash flows exceed the discount-rate hurdle in present-value terms; a negative NPV falls short of that hurdle.

How should I enter cash flows?
Use the same time interval for every cash flow and keep inflows positive and outflows negative.

What discount rate should I use?
Use a rate that matches the project risk, financing cost, or required return. The answer can change a lot if the discount rate is wrong.
