Depreciation Rate Calculator (Companies Act 2013)
Introduction & Importance of Depreciation Calculation
Understanding the legal requirements and financial implications
The Companies Act 2013 introduced significant changes to how businesses in India must calculate and account for depreciation. Section 123(2) of the Act mandates that companies must provide for depreciation in accordance with Schedule II, which prescribes specific useful lives for different asset classes and calculation methods.
Proper depreciation calculation is crucial for:
- Accurate financial reporting and compliance with Indian Accounting Standards (Ind AS)
- Tax planning and optimization under the Income Tax Act
- Asset valuation for mergers, acquisitions, and financial audits
- Determining true profitability and cash flow position
- Compliance with RBI guidelines for financial institutions
The Act specifies two primary methods for depreciation calculation:
- Straight Line Method (SLM): Equal annual depreciation over the asset’s useful life
- Written Down Value (WDV) Method: Higher depreciation in early years, decreasing over time
Schedule II of the Companies Act 2013 categorizes assets into 23 classes with prescribed useful lives ranging from 3 to 100 years. For example, computers have a 3-year useful life while buildings may have up to 60 years. The Act also introduced the concept of ‘component accounting’ where significant parts of an asset with different useful lives must be depreciated separately.
How to Use This Depreciation Calculator
Step-by-step guide to accurate calculations
- Enter Asset Cost: Input the original purchase price of the asset including all costs necessary to bring the asset to its working condition (installation, transportation, etc.)
- Specify Residual Value: Enter the estimated scrap value of the asset at the end of its useful life (typically 5-10% of original cost)
-
Select Useful Life: Choose from the dropdown based on Schedule II of Companies Act 2013:
- Computers: 3 years
- Furniture & Fixtures: 10 years
- Plant & Machinery: 15 years
- Buildings: 30-60 years
- Intangible Assets: 10 years
-
Choose Depreciation Method:
- Straight Line Method: Recommended for assets with consistent usage patterns
- Written Down Value: Preferred for assets that lose value quickly in early years (like technology)
-
Review Results: The calculator provides:
- Annual depreciation rate (%)
- Annual depreciation amount (₹)
- Total depreciation over asset life
- Visual depreciation schedule chart
- Interpret the Chart: The interactive graph shows year-by-year depreciation values and cumulative depreciation
Pro Tip: For component accounting, run separate calculations for each significant component with different useful lives (e.g., building structure vs. electrical installations).
Formula & Methodology Behind the Calculator
Understanding the mathematical foundation
1. Straight Line Method (SLM)
The formula for annual depreciation under SLM is:
Annual Depreciation = (Asset Cost – Residual Value) / Useful Life
Depreciation Rate (%) = (Annual Depreciation / Asset Cost) × 100
2. Written Down Value Method (WDV)
The WDV method uses a fixed percentage applied to the reducing balance each year. The formula is:
Depreciation Rate (%) = 1 – (Residual Value / Asset Cost)^(1/Useful Life)
Annual Depreciation = Opening WDV × Rate
Schedule II Rate Adjustment: The Companies Act 2013 allows companies to use rates different from Schedule II if they can justify the useful life based on technical evaluation. However, such deviations must be disclosed in financial statements.
Partial Year Depreciation: For assets purchased during the year, depreciation is calculated proportionately from the date of purchase to year-end. Our calculator assumes full-year depreciation for simplicity.
Change in Depreciation Method: Section 123(2) allows changes in depreciation method if:
- The change is required by statute or accounting standards
- The change results in more appropriate presentation of financial statements
All calculations comply with:
- Schedule II of Companies Act 2013
- Indian Accounting Standard (Ind AS) 16
- Income Tax Rules for depreciation under Section 32
Real-World Depreciation Examples
Practical case studies with actual numbers
Case Study 1: Manufacturing Plant Machinery
Scenario: A textile manufacturer purchases new weaving machinery for ₹50,00,000 with expected residual value of ₹5,00,000 and useful life of 15 years.
Straight Line Method:
Annual Depreciation = (₹50,00,000 – ₹5,00,000) / 15 = ₹3,00,000
Depreciation Rate = (₹3,00,000 / ₹50,00,000) × 100 = 6% per annum
Written Down Value Method:
Rate = 1 – (₹5,00,000/₹50,00,000)^(1/15) ≈ 17.46%
Year 1 Depreciation = ₹50,00,000 × 17.46% = ₹8,73,000
Tax Impact: The company can claim ₹8,73,000 in Year 1 under WDV vs ₹3,00,000 under SLM, providing significant tax savings in early years.
Case Study 2: IT Company Computers
Scenario: A software company buys 50 workstations at ₹80,000 each (total ₹40,00,000) with 5% residual value and 3-year life (as per Schedule II).
| Year | SLM Depreciation | WDV Depreciation | WDV Opening Balance |
|---|---|---|---|
| 1 | ₹12,66,667 | ₹16,33,975 | ₹40,00,000 |
| 2 | ₹12,66,667 | ₹11,04,123 | ₹23,66,025 |
| 3 | ₹12,66,666 | ₹7,47,405 | ₹12,61,902 |
| Total | ₹38,00,000 | ₹34,85,403 | – |
Key Insight: WDV provides 70% of total depreciation in Year 1 vs 33% under SLM, beneficial for rapidly obsolescing assets.
Case Study 3: Commercial Building
Scenario: A real estate firm constructs an office building for ₹2,00,00,000 with 10% residual value and 60-year life.
SLM Calculation:
Annual Depreciation = (₹2,00,00,000 – ₹20,00,000) / 60 = ₹3,00,000
Rate = 1.5% per annum
Component Accounting Application:
The building could be split into:
- Structure (60 years): ₹1,50,00,000
- Electrical (15 years): ₹20,00,000
- Plumbing (20 years): ₹15,00,000
- HVAC (10 years): ₹15,00,000
Tax Benefit: Component accounting accelerates depreciation on shorter-life components, improving cash flow.

-
Mid-Year Acquisition Handling:
- Depreciate assets purchased during the year proportionately
- For assets used <180 days in first year, claim 50% of normal depreciation
- Document purchase and commissioning dates carefully
-
Revaluation Considerations:
- Revalued assets must have depreciation calculated on revalued amount
- Create a revaluation reserve in equity
- Engage approved valuers for revaluation exercises
-
Disclosure Requirements:
- Disclose depreciation methods used in financial statements
- Reconcile depreciation charged with tax depreciation

Interactive FAQ on Depreciation Calculation
Expert answers to common questions
What happens if I don’t follow Schedule II depreciation rates?
Non-compliance with Schedule II can lead to:
- Financial Statement Qualifications: Auditors must qualify their report if depreciation isn’t as per Schedule II without proper justification
- Regulatory Penalties: Ministry of Corporate Affairs may impose fines under Section 134 for incorrect financial statements
- Tax Implications: Income Tax Department may disallow excessive depreciation claims
- Investor Concerns: Non-compliance may raise red flags with investors and lenders
However, companies can use different rates if they:
- Conduct a technical evaluation of the asset’s useful life
- Disclose the justification in financial statements
- Get auditor approval for the deviation
How does component accounting work under Companies Act 2013?
Component accounting requires separating an asset into significant parts with different useful lives. For example:
| Component | Cost (₹) | Useful Life | Annual Depreciation (₹) |
|---|---|---|---|
| Building Structure | 1,00,00,000 | 60 years | 1,66,667 |
| Electrical Wiring | 10,00,000 | 15 years | 66,667 |
| HVAC System | 15,00,000 | 10 years | 1,50,000 |
| Plumbing | 8,00,000 | 20 years | 40,000 |
| Total | 1,33,00,000 | – | 4,23,334 |
Benefits:
- More accurate financial reporting
- Accelerated depreciation on shorter-life components
- Better matching of expenses with revenue generation
Implementation Steps:
- Identify significant components (typically >5% of total asset cost)
- Determine appropriate useful lives for each component
- Maintain separate depreciation schedules
- Disclose component accounting policy in financial statements
Can I change the depreciation method after I’ve started using one?
Yes, but with important conditions:
Legal Requirements (Section 123(2)):
- The change must be required by statute or accounting standards
- OR the change must result in a more appropriate presentation of financial statements
- The change must be disclosed in the financial statements
- The impact of the change must be quantified
Practical Considerations:
- SLM to WDV: Generally allowed as it’s more conservative in early years
- WDV to SLM: Rarely justified as it would increase reported profits
- Tax Impact: May create temporary differences requiring deferred tax accounting
- Audit Scrutiny: Expect higher auditor scrutiny for method changes
Example Justification:
“The company has changed from SLM to WDV method for its IT equipment from FY 2023-24 onwards, as this better reflects the rapid technological obsolescence in the industry. This change has resulted in additional depreciation of ₹15,00,000 for the current year.”
How does depreciation under Companies Act differ from Income Tax Act?
Key differences between Companies Act 2013 and Income Tax Act 1961 depreciation provisions:
| Parameter | Companies Act 2013 | Income Tax Act 1961 |
|---|---|---|
| Governing Section | Section 123(2) + Schedule II | Section 32 |
| Purpose | Financial reporting | Tax deduction |
| Rate Determination | Based on useful life | Fixed percentage blocks |
| Building Rate | 1.67-3.17% | 5-10% |
| Plant & Machinery | 6.33-9.50% | 15% |
| Computers | 31.67% | 40/60% |
| Method Options | SLM or WDV | Only WDV (except for power generation) |
| Component Accounting | Mandatory for significant components | Not recognized |
| Additional Depreciation | Not applicable | 20% for new plant/machinery |
Tax Reconciliation:
Companies must maintain two depreciation calculations:
- Book Depreciation: As per Companies Act for financial statements
- Tax Depreciation: As per Income Tax Act for tax returns
Differences create:
- Deferred Tax Assets/Liabilities: When book and tax depreciation differ
- MAT Implications: Minimum Alternate Tax calculations use book profits
- Disclosure Requirements: Must be reconciled in tax audit reports
For most companies, tax depreciation > book depreciation, creating deferred tax liabilities.
What are the disclosure requirements for depreciation in financial statements?
Schedule III of Companies Act 2013 mandates comprehensive depreciation disclosures:
Balance Sheet Disclosures:
- Gross block of fixed assets
- Accumulated depreciation
- Net block (gross minus accumulated depreciation)
- Additions during the year
- Deductions during the year
Profit & Loss Disclosures:
- Total depreciation for the year
- Depreciation included in cost of assets (capitalized)
- Depreciation on revalued assets
Notes to Accounts:
- Depreciation methods used (SLM/WDV)
- Useful lives or rates used
- Justification for any deviation from Schedule II
- Details of component accounting if applied
- Impact of any change in depreciation method
Sample Disclosure:
Note 3: Depreciation and Amortization
Depreciation on fixed assets has been provided on the straight-line method based on useful lives prescribed in Schedule II to the Companies Act, 2013, except for the following assets where useful lives different from Schedule II have been used based on technical evaluation:
– Specialized manufacturing equipment: 8 years (Schedule II: 15 years)
– Custom software: 4 years (Schedule II: 3 years)
The carrying amounts of fixed assets would have been ₹1,25,00,000 higher if Schedule II lives had been used.
Component accounting has been applied to building assets with separate depreciation calculated for structure, electrical, and plumbing components.
Audit Requirements:
The auditor must specifically report whether:
- The company has provided depreciation as per Schedule II
- Any deviations are properly justified and disclosed
- The useful lives assigned are reasonable
- Component accounting has been properly applied where required
