Rate of Depreciation Calculator (Companies Act 2013)
Introduction & Importance of Depreciation as per Companies Act 2013
The Companies Act 2013 introduced significant changes to how businesses calculate and account for depreciation in India. This legislation, implemented by the Ministry of Corporate Affairs (MCA), mandates specific depreciation rates and methods that companies must follow for accurate financial reporting and tax compliance.
Depreciation under the Companies Act 2013 serves several critical purposes:
- Financial Accuracy: Ensures assets are valued correctly in financial statements
- Tax Compliance: Aligns with Income Tax Act requirements for deductions
- Investor Transparency: Provides clear information about asset valuation
- Regulatory Compliance: Meets MCA reporting standards for all registered companies
- Business Planning: Helps in accurate budgeting for asset replacement
The Act specifies different depreciation rates for various asset classes, ranging from buildings (5%) to computers (40%). Understanding these rates is crucial for:
- Preparing accurate financial statements
- Calculating correct tax liabilities
- Making informed business decisions about asset management
- Avoiding penalties for non-compliance with MCA regulations
For authoritative information, refer to the Ministry of Corporate Affairs official website and Income Tax Department guidelines.

- Calculate: Click the button to generate instant results showing annual depreciation rate, amounts, and projected values.
The calculator automatically applies the correct depreciation method (Straight Line or Written Down Value) as per the Companies Act 2013 guidelines for your selected asset type.
Formula & Methodology Behind the Calculator
The Companies Act 2013 (Schedule II) specifies two primary depreciation methods:
1. Straight Line Method (SLM)
Used for most assets except those where the Written Down Value method is mandatory.
Formula:
Annual Depreciation = (Original Cost – Residual Value) / Useful Life
Depreciation Rate = (Annual Depreciation / Original Cost) × 100
2. Written Down Value Method (WDV)
Mandatory for certain assets like computers, vehicles, and some plant & machinery.
Formula:
Annual Depreciation = (Opening WDV × Rate) / 100
Where Opening WDV = Original Cost – Accumulated Depreciation
| Asset Category | Rate (%) | Useful Life (Years) | Method |
|---|---|---|---|
| Building (General) | 5.38 | 60 | SLM |
| Plant & Machinery (General) | 15.33 | 15 | SLM/WDV |
| Furniture & Fixtures | 10.34 | 15 | SLM |
| Computers & IT Equipment | 40.00 | 3 | WDV |
| Vehicles | 31.23 | 8 | WDV |
| Intangible Assets | 25.00 | 10 | SLM |
Our calculator automatically:
- Selects the correct method (SLM/WDV) based on asset type
- Applies the statutory depreciation rate
- Calculates annual depreciation amounts
- Projects the written down value over the asset’s useful life
- Generates a visual depreciation schedule chart

Expert Tips for Depreciation Calculation & Compliance
Best Practices for Accurate Depreciation:
- Asset Classification: Always verify the correct asset category as per Schedule II. Misclassification can lead to incorrect rates and compliance issues.
- Component Accounting: For assets with distinct components (e.g., building with AC plants), depreciate each component separately based on its useful life.
- Useful Life Assessment: While the Act provides minimum useful lives, companies can use shorter lives if justified by technical evaluations.
- Residual Value: The standard 5% can be adjusted to nil for assets that typically have no salvage value (like certain IT equipment).
- Partial Year Depreciation: For assets purchased during the year, calculate depreciation on a pro-rata basis from the date of acquisition.
- Documentation: Maintain detailed records of asset purchases, classifications, and depreciation calculations for audit purposes.
- Software Implementation: Use accounting software that automatically applies Companies Act 2013 rates to minimize errors.
Common Mistakes to Avoid:
- Using Income Tax Act rates instead of Companies Act rates for financial statements
- Applying WDV method to assets that require SLM as per Schedule II
- Ignoring component accounting for complex assets
- Not adjusting depreciation when an asset’s useful life changes due to technological obsolescence
- Failing to account for assets purchased in the second half of the financial year (pro-rata rules apply)
- Using incorrect residual value percentages without proper justification
Advanced Strategies:
- Tax Optimization: For assets where both SLM and WDV are allowed, analyze which method provides better tax benefits based on your company’s profit projections.
- Asset Revaluation: When assets are revalued, calculate depreciation on the revalued amount and transfer the difference to revaluation reserve.
- Impairment Testing: Conduct annual impairment tests for assets that may have lost value beyond normal depreciation.
- Leased Assets: For leased assets, follow Ind AS 116 (if applicable) for proper depreciation treatment.
- Group Depreciation: For similar assets with similar useful lives, consider group depreciation to simplify calculations.
Interactive FAQ: Companies Act 2013 Depreciation
What is the key difference between Companies Act 2013 and Income Tax Act depreciation?
The Companies Act 2013 governs financial reporting while the Income Tax Act affects tax calculations. Key differences include:
- Different depreciation rates for several asset classes
- Companies Act allows both SLM and WDV for some assets, while Income Tax Act mandates specific methods
- Financial statements must use Companies Act rates, while tax returns use Income Tax Act rates
- Companies Act has more detailed asset classification requirements
Companies must maintain two separate depreciation calculations – one for books (Companies Act) and one for taxes (Income Tax Act).
Can a company use different depreciation methods for the same asset class?
No, the Companies Act 2013 requires consistency in depreciation methods. Once you choose a method (SLM or WDV) for an asset class, you must continue using it for all assets in that class. However:
- Different asset classes can use different methods (e.g., SLM for buildings, WDV for computers)
- You can change methods if there’s a significant change in the pattern of economic benefits
- Any method change must be disclosed in financial statements with proper justification
For example, you can’t use WDV for some computers and SLM for others – all computers must use the same method.
How is depreciation calculated for assets purchased during the year?
For assets acquired during the financial year, depreciation is calculated on a pro-rata basis from the date of acquisition to year-end. The formula is:
Pro-rata Depreciation = (Annual Depreciation × Remaining Months) / 12
Example: A machine purchased on November 1, 2023 (₹10,00,000, 15% SLM):
- Annual depreciation: ₹1,50,000
- Remaining months: 5 (Nov-Mar)
- Pro-rata depreciation: (₹1,50,000 × 5) / 12 = ₹62,500
Note: If an asset is purchased in the second half of the year (after September 30), some companies apply only 50% of the annual depreciation regardless of the exact purchase date.
What happens if an asset’s useful life changes after purchase?
If an asset’s useful life changes due to technological obsolescence, physical wear, or other factors, you must:
- Reassess the remaining useful life
- Adjust the depreciation rate prospectively (not retrospectively)
- Disclose the change in financial statements
- Calculate the revised annual depreciation based on the remaining carrying amount
Example: A machine with original life of 10 years (₹10,00,000 cost) has ₹6,00,000 book value after 5 years. If the remaining life is revised from 5 to 3 years:
New annual depreciation = ₹6,00,000 / 3 = ₹2,00,000 (instead of original ₹1,00,000)
Are there any assets that don’t require depreciation under Companies Act 2013?
Yes, certain assets are exempt from depreciation:
- Land (has unlimited useful life)
- Assets under construction (depreciation starts when put to use)
- Assets fully depreciated but still in use
- Assets held for sale (classified as current assets)
- Certain biological assets related to agricultural activity
- Assets that don’t lose value over time (like some art collections)
However, even exempt assets must be properly disclosed in financial statements with justification for why no depreciation is provided.
How does depreciation affect a company’s financial ratios?
Depreciation impacts several key financial ratios:
| Financial Ratio | Impact of Higher Depreciation | Impact of Lower Depreciation |
|---|---|---|
| Profit Margins | Decreases (higher expense) | Increases |
| Return on Assets (ROA) | Decreases | Increases |
| Debt-to-Equity | Increases (lower equity) | Decreases |
| Asset Turnover | Increases (lower asset value) | Decreases |
| Cash Flow | No direct impact (non-cash expense) | No direct impact |
Investors and analysts often add back depreciation to earnings when evaluating cash flow performance, as it’s a non-cash expense that can distort profitability metrics.
What are the penalties for incorrect depreciation calculation?
Non-compliance with Companies Act 2013 depreciation rules can result in:
- Financial Restatements: Requirement to refile corrected financial statements
- Regulatory Penalties: Fines from MCA for material misstatements (up to ₹50,000 for companies and ₹5,000 for officers)
- Tax Implications: Income Tax Department may disallow incorrect depreciation claims
- Audit Qualifications: Auditors may qualify their opinion on financial statements
- Investor Lawsuits: Shareholders may take legal action for misleading financial information
- Credit Rating Impact: Rating agencies may downgrade due to accounting irregularities
To avoid penalties, implement strong internal controls including:
- Regular depreciation policy reviews
- Independent verification of asset classifications
- Automated depreciation calculation systems
- Periodic audits of fixed asset registers
