Deep dive
How to think about Net Present Value (NPV)
NPV is a cornerstone of financial analysis. A positive NPV means the projected earnings exceed the anticipated costs, adjusted for the time value of money. It is considered one of the most reliable methods for evaluating long-term investments because it accounts for risk through the discount rate.
Example: A company evaluates a $1M investment expected to generate $300K annually for 5 years. At a 10% discount rate, the present value of cash flows is $1.137M. NPV = $1.137M - $1M = $137K. Since NPV > 0, the project adds value.

NPV is the difference between the present value of cash inflows and outflows over a period of time, discounted at a specific rate.
A company evaluates a $1M investment expected to generate $300K annually for 5 years. At a 10% discount rate, the present value of cash flows is $1.137M. NPV = $1.137M - $1M = $137K. Since NPV > 0, the project adds value.
In an interview, define Net Present Value (NPV), explain where it appears in a real finance workflow, then name one assumption or limitation that a reviewer should check.
