Definition§
The Net Present Value (NPV) Rule is the principle which states that managers and investors should only pursue projects or investments with a positive NPV, meaning that the present value of anticipated cash inflows exceeds the present value of cash outflows. Conversely, they should steer clear of ventures with a negative NPV, as they signify a likely loss.
NPV Rule vs IRR Rule Comparison§
| Feature | Net Present Value (NPV) Rule | Internal Rate of Return (IRR) Rule |
|---|---|---|
| Decision focus | Positive NPV projects only | IRR must exceed the required rate of return |
| Time value of money | Explicitly considers | Implicitly accounts |
| Cash flow patterns | Can handle non-standard patterns | Difficult with non-conventional cash flows |
| Conflicts | Less prone to conflicts | May lead to multiple or conflicting IRR values |
| Complexity | Straightforward calculation | Requires iterative calculations |
Example§
Imagine a project requiring an initial investment of $1,000 and promising cash inflows of $300 annually for the next 5 years. If we assume a discount rate of 10%, the NPV is:
- Yearly inflows: $300
- Discounted inflows:
- Year 1: $300 / (1+0.10)^1 = $272.73
- Year 2: $300 / (1+0.10)^2 = $247.93
- Year 3: $300 / (1+0.10)^3 = $225.39
- Year 4: $300 / (1+0.10)^4 = $204.90
- Year 5: $300 / (1+0.10)^5 = $186.27
Total present value of inflows = $272.73 + $247.93 + $225.39 + $204.90 + $186.27 = $1137.22
NPV = Total PV of inflows - Initial Investment = $1137.22 - $1000 = $137.22
Since the NPV is positive ($137.22), the investment is deemed favorable!

Frequently Asked Questions§
Q1: Why is NPV important?
A1: NPV is crucial because it provides a direct value of an investment’s profitability — making things much clearer than staring into a crystal ball!
Q2: What if my NPV is zero?
A2: A zero NPV means you break even. It’s like washing your hands after touching the stock market: you leave with what you came with!
Q3: Can NPV be negative but still attract investment?
A3: Yes, but that would usually indicate your investors had something stronger than logic — perhaps an affinity for risk or a very compelling pitcher!
