Discuss NPV method for making capital budgeting decisions with suitable examples.

Introduction

The Net Present Value (NPV) method is one of the most widely used techniques for evaluating investment and capital budgeting decisions. It considers the time value of money and provides a clear indication of whether a project will generate value for the firm. This article explains the NPV method, its process, benefits, and includes examples to illustrate its application.

What is NPV?

NPV is the difference between the present value of cash inflows and the present value of cash outflows over a period of time. It measures the net increase in value for the firm from an investment project. A positive NPV indicates that the projected earnings (in present value terms) exceed the anticipated costs, while a negative NPV suggests a loss.

Formula:

NPV = Σ [Ct / (1 + r)^t] – C₀

Where:
Ct = Net cash inflow during the period t
r = Discount rate
t = Time period
C₀ = Initial investment

Steps in NPV Method

Estimate Future Cash Flows: Predict the net inflows expected from the investment.
Select an Appropriate Discount Rate: Typically the firm’s cost of capital or required rate of return.
Calculate Present Value: Discount each of the future cash flows to present value.
Subtract Initial Investment: The initial cost of the project is subtracted from the total PV of inflows to derive NPV.
Decision Rule: Accept the project if NPV > 0; reject if NPV < 0.

Example:

Project A requires an initial investment of ₹100,000 and is expected to generate ₹30,000 per year for 5 years. Assume a discount rate of 10%.

Using the NPV formula:
PV = ₹30,000 × [1 – (1 + 0.10)^-5] / 0.10 = ₹113,730
NPV = ₹113,730 – ₹100,000 = ₹13,730

Conclusion: Since NPV is positive, Project A is acceptable.

Advantages of NPV Method

Considers the time value of money
Provides a direct measure of value addition
Useful for comparing multiple investment options
Adjustable for risk via discount rate

Limitations of NPV Method

Estimation of future cash flows can be uncertain
Choice of discount rate can influence the result
Ignores non-financial factors like brand value or employee satisfaction

Conclusion

The NPV method is a robust tool for capital budgeting decisions, offering clear insight into whether a project will be profitable. By focusing on cash flows and time value, it supports rational investment decision-making and value maximization for shareholders.
