Capital Budgeting in India: Complete Guide to Investment Decisions

Introduction: The Art of Saying Yes or No to Millions

Tata Steel faces a decision: invest ₹35,000 crore in a new plant in Odisha or not. The wrong choice could mean billions in losses; the right choice could secure the company’s future for decades. How do corporate leaders make such monumental decisions?

Welcome to capital budgeting—the systematic process of evaluating major investments. Whether you’re a CFO deciding on a ₹10,000 crore expansion or a small business owner considering a ₹50 lakh machine purchase, capital budgeting principles remain the same.

Cash Flow Estimation

The Foundation of Capital Budgeting

Principle: Focus on incremental cash flows, not accounting profits.

Types of Cash Flows

Calculating Operating Cash Flow

Formula:

$$OCF = (Revenue - Costs)(1 - Tax) + Depreciation \times Tax$$

Or:

$$OCF = EBIT(1 - Tax) + Depreciation$$

Example: New Machine Investment

Given:

• Machine cost: ₹50 lakh
• Installation: ₹5 lakh
• Additional working capital: ₹10 lakh
• Annual revenue increase: ₹40 lakh
• Annual cost savings: ₹10 lakh
• Annual depreciation: ₹11 lakh
• Tax rate: 25%
• Project life: 5 years
• Salvage value: ₹5 lakh

Initial Investment (Year 0):

Machine cost:        ₹50,00,000
Installation:        ₹ 5,00,000
Working capital:     ₹10,00,000
Total:               ₹65,00,000

Annual Operating Cash Flow:

Revenue increase:    ₹40,00,000
Cost savings:        ₹10,00,000
Total benefit:       ₹50,00,000

Less: Depreciation:  ₹11,00,000
EBIT:                ₹39,00,000

Less: Tax (25%):     ₹ 9,75,000
Net Income:          ₹29,25,000

Add: Depreciation:   ₹11,00,000
OCF:                 ₹40,25,000

Terminal Cash Flow (Year 5):

Salvage value:       ₹ 5,00,000
Tax on gain:         ₹ 1,25,000  (assuming book value is zero)
After-tax salvage:   ₹ 3,75,000
Working capital:     ₹10,00,000
Terminal CF:         ₹13,75,000

Important Concepts

Sunk Costs:

• Already incurred costs
• Should NOT be included
• Example: Market research already done

Opportunity Costs:

• Value of next best alternative
• SHOULD be included
• Example: Using existing land (include market value)

Externalities:

• Effects on other company projects
• Cannibalization effects
• Synergies with existing operations

Capital Budgeting Techniques

Overview of Methods

1. Payback Period

Definition: Time required to recover initial investment.

Formula:

$$Payback\ Period = \frac{Initial\ Investment}{Annual\ Cash\ Flow}$$

(For uneven cash flows, calculate cumulative cash flows)

Example:

Investment: ₹100 lakh
Annual CF: ₹25 lakh

Payback = ₹100 lakh ÷ ₹25 lakh = 4 years

Decision Rule:

• Accept if Payback < Maximum acceptable period
• Lower payback = Better

Advantages:

• Simple and intuitive
• Emphasizes liquidity
• Risk indicator

Disadvantages:

• Ignores time value of money
• Ignores cash flows after payback
• No objective criterion

2. Net Present Value (NPV)

Definition: Present value of all cash flows minus initial investment.

Formula:

$$NPV = \sum_{t=0}^{n} \frac{CF_t}{(1+r)^t}$$

Where:

• CF_t = Cash flow at time t
• r = Discount rate (required return)
• n = Project life

Example:

Investment: ₹100 lakh
CF Years 1-5: ₹30 lakh each
Discount rate: 12%

NPV = -100 + 30/1.12 + 30/1.12² + 30/1.12³ + 30/1.12⁴ + 30/1.12⁵
NPV = -100 + 26.79 + 23.92 + 21.36 + 19.07 + 17.02
NPV = ₹8.16 lakh

Decision Rule:

• NPV > 0 → Accept
• NPV < 0 → Reject
• NPV = 0 → Indifferent

Advantages:

• Considers time value of money
• Considers all cash flows
• Measures absolute value creation
• Theoretically correct

Disadvantages:

• Requires discount rate estimation
• May not suit capital rationing
• Doesn’t show rate of return

3. Internal Rate of Return (IRR)

Definition: Discount rate that makes NPV equal to zero.

Formula:

$$0 = \sum_{t=0}^{n} \frac{CF_t}{(1+IRR)^t}$$

Calculation: Trial and error or Excel/calculator

Example:

Investment: ₹100 lakh
CF Years 1-3: ₹50 lakh each

At IRR: -100 + 50/(1+IRR) + 50/(1+IRR)² + 50/(1+IRR)³ = 0

IRR ≈ 23.4%

Decision Rule:

• IRR > Required return → Accept
• IRR < Required return → Reject

Advantages:

• Considers time value
• Easy to understand (percentage return)
• No need to estimate discount rate first

Disadvantages:

• Multiple IRRs possible (non-conventional CF)
• Reinvestment assumption unrealistic
• May conflict with NPV for mutually exclusive projects

4. Profitability Index (PI)

Definition: Ratio of present value of benefits to initial cost.

Formula:

$$PI = \frac{PV\ of\ Future\ Cash\ Flows}{Initial\ Investment}$$

Example:

PV of inflows: ₹108.16 lakh
Initial investment: ₹100 lakh

PI = 108.16/100 = 1.08

Decision Rule:

• PI > 1 → Accept
• PI < 1 → Reject

Advantages:

• Useful for capital rationing
• Shows return per rupee invested

Disadvantages:

• May conflict with NPV
• Absolute value not shown

Comparing Techniques: NPV vs IRR

When They Agree

For independent projects with conventional cash flows:

• If NPV > 0, then IRR > required return
• Decision is the same

When They Conflict

Mutually Exclusive Projects:

IRR says: Choose B (higher IRR) NPV says: Choose A (higher NPV)

Resolution: NPV is theoretically correct for value maximization

Multiple IRR Problem

When cash flows change sign more than once, multiple IRRs are possible.

Example:

• Year 0: -₹100 lakh
• Year 1: +₹230 lakh
• Year 2: -₹132 lakh

This can have two IRRs: 10% and 20%

Solution: Use NPV or MIRR instead

Risk Analysis in Capital Budgeting

1. Sensitivity Analysis

Definition: Testing how NPV changes with changes in one variable at a time.

Example:

Insight: Project is most sensitive to sales volume

2. Scenario Analysis

Definition: Evaluating NPV under different scenarios.

3. Break-Even Analysis

Definition: Finding the value of a variable at which NPV = 0.

Example:

• What sales volume makes NPV = 0?
• What discount rate makes NPV = 0? (This is IRR)

4. Monte Carlo Simulation

Definition: Running thousands of scenarios with probabilistic inputs.

Process:

1. Define probability distributions for key variables
2. Generate random values
3. Calculate NPV for each combination
4. Analyze distribution of NPVs

Capital Rationing

What is Capital Rationing?

When a company has more good projects than capital available.

Types

Hard Rationing: External constraint (can’t raise more capital) Soft Rationing: Internal constraint (management-imposed limits)

Solution Approach

Rank projects by Profitability Index:

Budget: ₹150 lakh

Selection: A (₹50L) + B (₹100L) = ₹150L invested Total NPV: ₹15L + ₹25L = ₹40L

Capital Budgeting in Indian Context

Unique Considerations

1. Higher Discount Rates:

• Risk-free rate higher (6-7%)
• Equity premium significant
• Cost of capital: 12-18% typical

2. Regulatory Environment:

• Environmental clearances
• Land acquisition challenges
• Labor laws

3. Tax Considerations:

• Depreciation rates (IT Act)
• Investment allowances
• SEZ benefits

4. Currency Risk:

• For import-dependent projects
• Export revenue projects
• Dollar-denominated loans

Real Options in India

Concept: Value of flexibility in investment decisions.

Examples:

• Option to expand (if market grows)
• Option to abandon (if market declines)
• Option to delay (wait for clarity)

Relevance:

• High uncertainty in Indian markets
• Regulatory changes possible
• Economic volatility

Frequently Asked Questions

Q: Which is better – NPV or IRR? A: NPV is theoretically correct for value maximization. IRR is useful for communication. Use both, but trust NPV when they conflict.

Q: What discount rate should I use? A: Use company’s Weighted Average Cost of Capital (WACC), adjusted for project-specific risk.

Q: How do I estimate cash flows? A: Use market research, historical data, industry benchmarks, and conservative assumptions. Build scenarios.

Q: What is a good NPV? A: NPV > 0 is acceptable. Higher is better. Consider NPV relative to investment size.

Q: How do large Indian companies do capital budgeting? A: Most use NPV and IRR. Large groups like Tata, Reliance have sophisticated financial planning teams with detailed models.

Q: Should I include inflation in cash flows? A: Be consistent – use nominal cash flows with nominal discount rate, or real cash flows with real discount rate.

Capital budgeting is where finance meets strategy. The techniques are mathematical, but the judgment calls—which projects fit our vision, how much risk can we take, what does the future hold—are deeply human. Master the numbers, but never forget the strategic context.
