Types of Capital Expenditures
Capital Expenditure (Capex) = Funds used to acquire, upgrade, or maintain physical assets
Capex appears on the Balance Sheet (PP&E) and is expensed over time through Depreciation.
🔧 Maintenance Capex
Spending to maintain current operations
- Replace worn-out equipment
- Repair and upkeep of existing assets
- Does NOT increase capacity
- Usually equals Depreciation expense
🚀 Growth Capex
Spending to expand the business
- New factories, stores, warehouses
- Geographic expansion
- Increases productive capacity
- Drives future revenue growth
How to forecast Capex:
• Maintenance Capex = Depreciation (or % of Gross PP&E)
• Growth Capex = Based on expansion plans or % of incremental revenue
• Total Capex = Maintenance + Growth
Capex Forecasting Approaches
Common Capex Forecasting Methods
| Method | Formula | Best For |
|---|---|---|
| % of Revenue | Capex = Revenue × Capex % | Mature, stable companies |
| Fixed Asset Turnover | Capex = (Revenue / FAT) - Existing Net PP&E | Asset-intensive industries |
| Management Guidance | Use disclosed capex plans | All companies (if available) |
| Depreciation + Growth | Capex = Depreciation + Growth Capex % | Growing companies |
Example: TCS Capex Forecast (% of Revenue Method)
| Item | 2025A | 2026E | 2027E | 2028E |
|---|---|---|---|---|
| Revenue | 289,456 | 318,402 | 350,242 | 385,266 |
| Capex % of Revenue | 13.8% | 14.0% | 14.0% | 14.0% |
| Capex | 39,930 | 44,576 | 49,034 | 53,937 |
Example 2026E: =318,402 * 14% = 44,576
Depreciation Methods
Depreciation allocates the cost of a tangible asset over its useful life.
It's a non-cash expense that reduces taxable income but does NOT reduce cash.
Straight-Line Depreciation (Most Common)
' Example: Asset costing ₹10,00,000, salvage ₹50,000, 10-year life
=SLN(1000000, 50000, 10)
' Returns: ₹95,000 per year
Depreciation Schedule: Multiple Asset Classes
| Asset Class | Cost (₹) | Salvage (₹) | Life (Years) | Annual Depr. (₹) | Excel Formula |
|---|---|---|---|---|---|
| Buildings | 10,000,000 | 500,000 | 30 | 316,667 | =SLN(10000000,500000,30) |
| Machinery | 5,000,000 | 250,000 | 10 | 475,000 | =SLN(5000000,250000,10) |
| Computers | 2,000,000 | 100,000 | 5 | 380,000 | =SLN(2000000,100000,5) |
| Vehicles | 1,500,000 | 100,000 | 7 | 200,000 | =SLN(1500000,100000,7) |
| Furniture | 800,000 | 50,000 | 10 | 75,000 | =SLN(800000,50000,10) |
| TOTAL | 19,300,000 | 1,000,000 | - | 1,446,667 | - |
Hands-On: Build Depreciation Schedule
📥 Download Practice File
⬇ Download lecture-06-capex-data.csv🎯 Exercise: Create Depreciation Schedule
Task 1: Set Up Asset Schedule
- Create a new sheet named "Depreciation"
- Set up columns: Asset Class, Cost, Salvage, Life, Annual Depr
- Enter the 5 asset classes from the table above
Task 2: Calculate Annual Depreciation
Use the SLN function for each asset:
=SLN(B2, C2, D2)
' Or manually:
=(B2-C2)/D2
Task 3: Build 5-Year Schedule
| Year | Buildings | Machinery | Computers | Vehicles | Furniture | Total |
|---|---|---|---|---|---|---|
| 1 | 316,667 | 475,000 | 380,000 | 200,000 | 75,000 | 1,446,667 |
| 2 | 316,667 | 475,000 | 380,000 | 200,000 | 75,000 | 1,446,667 |
| ... | ... | ... | ... | ... | ... | ... |
| 5 | 316,667 | 475,000 | 0 | 200,000 | 75,000 | 1,066,667 |
Note: Computers are fully depreciated after Year 5 (shown in yellow)
Task 4: Verify Results
- Year 1-5 Total Depreciation should be 1,446,667
- Year 6+ (after computers fully depreciated): 1,066,667
- Check: Total depreciation over all years = Cost - Total Salvage
Key Takeaways
- Maintenance Capex ≈ Depreciation (maintains current operations)
- Growth Capex expands capacity and drives future revenue
- Capex % of Revenue is the most common forecasting method
- SLN function in Excel calculates straight-line depreciation
- Depreciation is non-cash - added back in cash flow statement
