Capital Budgeting Decisions: NPV, IRR, and Payback Explained Practically

Vinu: Manu, when a company plans a major investment, how should finance executives evaluate it?

Manu: Through capital budgeting, Vinu. The goal is simple—invest ₹1 today only if it creates more than ₹1 in value tomorrow.

Vinu: Let’s start with NPV. What does it actually tell us?

Manu: Net Present Value (NPV) measures value creation. Suppose a project requires ₹2 crore investment and generates discounted cash inflows of ₹2.5 crore.

NPV = ₹50 lakh. That means real value addition of ₹50 lakh—so it’s a good decision.

VinuAnd if NPV is negative?

ManuThen the project destroys value. Even if it shows accounting profit, it’s not worth investing.

VinuWhat about IRR?

ManuInternal Rate of Return (IRR) is the return the project generates. If IRR is 18% and the company’s cost of capital is 12%, the project is financially attractive.

Vinu: So IRR is like comparing returns?

Manu: Exactly. But don’t rely on IRR alone—NPV is more reliable for decision-making.

VinuWhere does Payback Period fit in?

Manu: It measures how quickly the investment is recovered. If a ₹2 crore project generates ₹50 lakh annually, payback is 4 years.

Vinu: That sounds simple. What’s the limitation?

ManuPayback ignores returns after recovery and doesn’t consider time value of money. It’s useful for liquidity assessment, not profitability.

Vinu: How should executives use all three together?

ManuUse NPV to check value creation

Use IRR to compare returns

Use Payback to assess risk and liquidity

For example, between two projects—one with NPV ₹60 lakh and another ₹40 lakh—choose the higher NPV, even if IRR is slightly lower.

Vinu: What’s a common mistake businesses make?

ManuApproving projects based on intuition or short payback, ignoring long-term value.

Vinu: Final takeaway?

ManuCapital budgeting is about disciplined investment.

Always ask—Is this project creating value, generating adequate return, and recovering cash within an acceptable time?

Vinu: Clear and practical—numbers should drive investment decisions.
