- Compare options at the same discount rate.
- See whether an investment adds value (NPV above zero).
Frequently asked questions
What does NPV tell me?
NPV is the value today of future cash flows minus the upfront cost. A positive NPV means the investment is expected to add value at your discount rate.
How do I enter the cash flows?
List them in order, separated by commas or new lines. The first value is usually the initial investment entered as a negative number.
