Depreciation Rates Calculator as per Companies Act 2013
Module A: Introduction & Importance of Depreciation as per Companies Act 2013
The Companies Act 2013 introduced significant changes to how businesses calculate and report depreciation in India. This legislation, implemented by the Ministry of Corporate Affairs, mandates specific depreciation rates and methods that companies must follow for accurate financial reporting and tax compliance.
Depreciation represents the systematic allocation of an asset’s cost over its useful life. Under the Companies Act 2013, companies must use the Written Down Value (WDV) method for most assets, though some exceptions apply. Proper depreciation calculation is crucial for:
- Accurate financial statement preparation
- Tax deduction optimization
- Compliance with statutory requirements
- Proper asset valuation for business decisions
- Investor and stakeholder transparency
The Act specifies different depreciation rates for various asset classes, ranging from 5% for buildings to 40% for computers and electronic equipment. These rates are designed to reflect the actual wear and tear of assets over time.

Module C: Formula & Methodology
The Companies Act 2013 primarily uses the Written Down Value (WDV) method for depreciation calculation. The formula for annual depreciation is:
Annual Depreciation = (Depreciation Rate / 100) × (Asset Cost – Accumulated Depreciation)
Written Down Value = Asset Cost – Accumulated Depreciation
Where:
- Depreciation Rate: Percentage as per Schedule II of Companies Act 2013
- Asset Cost: Original purchase price of the asset
- Accumulated Depreciation: Total depreciation charged to date
The Act specifies these key provisions:
- Assets are grouped into categories with specific rates
- Useful life is determined based on asset type
- Residual value cannot exceed 5% of original cost
- Depreciation begins when the asset is ready for use
- Pro-rata depreciation applies for assets used for part of a year
For assets purchased before the Act came into effect, companies must adjust the remaining useful life and depreciation rates accordingly.
Module D: Real-World Examples
Example 1: Office Building
Scenario: A company purchases an office building for ₹5,000,000 with an expected useful life of 20 years and 5% residual value.
Calculation:
- Depreciation rate: 5% (as per Schedule II)
- Depreciable amount: ₹5,000,000 × (1 – 0.05) = ₹4,750,000
- Annual depreciation: ₹4,750,000 × 5% = ₹237,500
- WDV after Year 1: ₹5,000,000 – ₹237,500 = ₹4,762,500
Example 2: Manufacturing Plant
Scenario: A manufacturing company installs new machinery costing ₹2,500,000 with a 15% depreciation rate and 10-year useful life.
Calculation:
- Depreciation rate: 15%
- Depreciable amount: ₹2,500,000 × (1 – 0.05) = ₹2,375,000
- Annual depreciation: ₹2,375,000 × 15% = ₹356,250
- WDV after Year 1: ₹2,500,000 – ₹356,250 = ₹2,143,750
Example 3: IT Equipment
Scenario: A tech startup purchases computers worth ₹1,200,000 with a 40% depreciation rate and 3-year useful life.
Calculation:
- Depreciation rate: 40%
- Depreciable amount: ₹1,200,000 × (1 – 0.05) = ₹1,140,000
- Annual depreciation: ₹1,140,000 × 40% = ₹456,000
- WDV after Year 1: ₹1,200,000 – ₹456,000 = ₹744,000
Module E: Data & Statistics
Understanding depreciation rates across different asset classes helps businesses make informed financial decisions. Below are comparative tables showing standard rates and their impact on asset valuation.

Module F: Expert Tips for Accurate Depreciation Calculation
Best Practices:
- Always maintain proper asset registers with purchase dates and costs
- Review depreciation rates annually for any regulatory changes
- Use separate depreciation schedules for different asset categories
- Document the rationale for any custom depreciation rates used
- Consider tax implications when choosing between WDV and SLM methods
Common Mistakes to Avoid:
- Using incorrect depreciation rates for asset categories
- Failing to adjust for partial-year usage
- Ignoring residual value limitations (max 5%)
- Not reconciling book depreciation with tax depreciation
- Overlooking asset revaluations and their impact
Advanced Considerations:
- For assets used in multiple shifts, consider higher depreciation rates (up to 50% more)
- Account for technological obsolescence in IT equipment depreciation
- Review useful life estimates periodically based on actual asset performance
- Consider component accounting for major asset components with different lives
- Document impairment tests for assets that may have reduced in value
Module G: Interactive FAQ
What is the difference between WDV and SLM depreciation methods?
The Written Down Value (WDV) method applies the depreciation rate to the reducing balance of the asset each year, resulting in higher depreciation in early years. The Straight Line Method (SLM) spreads the depreciation evenly over the asset’s useful life.
Companies Act 2013 primarily mandates WDV method, though SLM can be used for certain assets like intangibles with the approval of the Central Government.
How does the Companies Act 2013 handle assets purchased before its implementation?
For assets acquired before April 1, 2014, companies must:
- Determine the remaining useful life as per Schedule II
- Calculate the carrying amount after depreciation until March 31, 2014
- Depreciate the remaining amount over the revised useful life
The residual value cannot exceed 5% of the original cost, even for older assets.
Can we use different depreciation rates for tax and accounting purposes?
While Companies Act 2013 governs accounting depreciation, the Income Tax Act has separate provisions. Companies often maintain two sets of books:
- Accounting Books: Follow Companies Act rates (WDV method)
- Tax Books: Follow Income Tax Act rates (often higher)
Differences create deferred tax assets/liabilities that must be disclosed in financial statements.
What happens if an asset’s useful life changes after purchase?
If an asset’s useful life changes due to technological advancements, physical wear, or other factors:
- Reassess the remaining useful life
- Adjust the depreciation rate prospectively
- Disclose the change in accounting policies
- Calculate depreciation on the revised remaining life
This is considered a change in accounting estimate, not a correction of error.
How should we handle assets used for less than a full year?
For assets used for part of a year, Companies Act 2013 requires pro-rata depreciation based on the number of days the asset was available for use:
Formula: (Annual Depreciation × Days Used) / 365
Example: An asset purchased on October 1 would have depreciation calculated for 181 days (from October 1 to March 31).
