NPV = Sum of [Cash Flow in Year t / (1 + Discount Rate)^t] – Initial Investment
Example:
For founders: NPV is how you evaluate every major capital allocation decision: should you hire 5 more engineers? Open a new market? Build a new product line? Acquire a company? Each of these is an investment with expected cash flows that should be discounted at your cost of capital.
1. Overly optimistic cash flows: Use realistic projections, not best-case. Run three scenarios: base, bull, and bear. If NPV is negative in the base case, do not invest just because the bull case looks amazing.
2. Wrong discount rate: Using the risk-free rate (7%) when the project carries significant risk understates the required return and inflates NPV. Use WACC for average-risk projects and add a risk premium for speculative ones.
3. Ignoring terminal value: For projects with cash flows beyond the projection period, include a terminal value. This often represents 50-70% of total NPV, so getting the terminal growth rate right is critical.

FAQs about NPV Calculator
NPV (Net Present Value) is the difference between present value of future cash flows and initial investment. It accounts for time value of money. Positive NPV means the investment creates value.
Use WACC for corporate projects. For startups, 15-25% depending on risk. For personal investments, use opportunity cost. In India, 12-18% is common for business investments.
The investment destroys value. Present value of returns is less than what you invest. Re-evaluate assumptions: are cash flows too conservative? Is the discount rate too high?
ROI is simple profit/investment percentage. NPV accounts for time value of money. Rs 1 Cr in 5 years is worth less than Rs 1 Cr today. For multi-year investments, NPV is far more reliable.
PI = PV of cash flows / Initial investment. Above 1.0 means positive NPV. Useful for ranking capital-constrained projects. PI of 1.5 means every rupee generates Rs 1.50 in present value.
Yes, DCF valuation IS NPV applied to a business. Project free cash flows for 5-10 years, add terminal value, discount at WACC. Most rigorous valuation method, but assumptions matter enormously.
Only as good as your projections and discount rate. Garbage in, garbage out. Assumes reinvestment at discount rate. For uncertain projects, supplement with scenario analysis.
