Depreciation Schedule (WDV Method)
Comprehensive Guide: How to Calculate Depreciation Rate Using WDV Method
The Written Down Value (WDV) method, also known as the diminishing balance method, is a depreciation technique where the asset’s value is reduced by a fixed percentage each year. This method is particularly useful for assets that lose more value in their early years of use.
Key Features of WDV Method
- Higher depreciation in early years – Reflects the actual usage pattern of many assets
- Never fully depreciates to zero – Leaves a residual salvage value
- Tax benefits – Often preferred by businesses for tax planning
- Complies with accounting standards – Recognized by GAAP and IFRS
WDV Depreciation Formula
The basic formula for calculating depreciation using the WDV method is:
Depreciation for Year = (Net Book Value at Beginning × Depreciation Rate) / 100
Where:
- Net Book Value = Cost of Asset – Accumulated Depreciation
- Depreciation Rate = Percentage applied to the reducing balance
Step-by-Step Calculation Process
- Determine initial cost – The original purchase price of the asset
- Establish salvage value – The estimated value at the end of useful life
- Set useful life – The period over which the asset will be depreciated
- Choose depreciation rate – Typically higher than straight-line method
- Calculate annual depreciation – Apply the rate to the reducing balance
- Prepare depreciation schedule – Track the asset’s value over its life
WDV vs Straight Line Method Comparison
| Feature | WDV Method | Straight Line Method |
|---|---|---|
| Depreciation Pattern | Higher in early years, decreases over time | Equal amount every year |
| Tax Implications | Better tax savings in early years | Consistent tax deduction |
| Book Value | Never reaches zero (salvage value remains) | Reaches zero at end of useful life |
| Complexity | More complex calculations | Simple and straightforward |
| Best For | Assets that lose value quickly (vehicles, computers) | Assets with consistent usage (buildings, furniture) |
Real-World Example: Vehicle Depreciation
Let’s consider a commercial vehicle with the following details:
- Initial cost: ₹10,00,000
- Salvage value: ₹1,00,000
- Useful life: 5 years
- Depreciation rate: 40%
| Year | Opening Value | Depreciation | Closing Value |
|---|---|---|---|
| 1 | ₹10,00,000 | ₹4,00,000 | ₹6,00,000 |
| 2 | ₹6,00,000 | ₹2,40,000 | ₹3,60,000 |
| 3 | ₹3,60,000 | ₹1,44,000 | ₹2,16,000 |
| 4 | ₹2,16,000 | ₹86,400 | ₹1,29,600 |
| 5 | ₹1,29,600 | ₹29,600 | ₹1,00,000 |
Advantages of WDV Method
- Better matches actual usage – Many assets lose value faster in early years
- Tax benefits – Higher depreciation in early years reduces taxable income
- More accurate financial reporting – Reflects the true economic value of assets
- Flexibility – Can choose different rates for different asset classes
- Compliance – Accepted by tax authorities and accounting standards
Disadvantages to Consider
- Complex calculations – Requires tracking of reducing balance each year
- Never fully depreciated – Asset value never reaches zero (except salvage value)
- Inconsistent expenses – Different depreciation amounts each year
- Potential for manipulation – Choice of rate can significantly impact financials
When to Use WDV Method
The WDV method is particularly suitable for:
- Assets that lose value quickly in early years (vehicles, computers, mobile phones)
- Businesses looking to maximize tax benefits in early years of asset ownership
- Assets with high maintenance costs that increase over time
- Technological equipment that becomes obsolete quickly
- Situations where accounting standards require or recommend WDV
Legal and Accounting Standards
The WDV method is recognized by major accounting standards:
- Indian Accounting Standards (Ind AS) – Permits WDV method under Ind AS 16
- Income Tax Act, 1961 – Section 32 provides for WDV method depreciation
- International Financial Reporting Standards (IFRS) – Allows WDV under IAS 16
- Generally Accepted Accounting Principles (GAAP) – Accepted in many jurisdictions
Common Mistakes to Avoid
- Using wrong rate – The rate should reflect the actual usage pattern
- Ignoring salvage value – Must be considered in calculations
- Incorrect useful life – Should match the asset’s economic life
- Mixing methods – Shouldn’t switch between WDV and straight-line
- Not documenting assumptions – Rates and lives should be justified
- Forgetting tax implications – Different methods have different tax treatments
WDV Method in Different Countries
| Country | Standard | Typical Rates | Special Provisions |
|---|---|---|---|
| India | Income Tax Act, 1961 | 15%-40% | Higher rates for certain industries |
| United States | MACRS (Modified ACCRS) | Varies by asset class | 150% or 200% declining balance |
| United Kingdom | Capital Allowances | 8%-18% | First-year allowances available |
| Australia | Taxation Ruling TR 2000/18 | Varies by asset | Simplified depreciation for SMEs |
| Canada | Capital Cost Allowance (CCA) | Varies by asset class | Different classes for different assets |

Frequently Asked Questions
1. Can I switch from WDV to straight-line method?
Generally no. Accounting standards require consistency in depreciation methods. Switching methods would require justification and may need approval from auditors or tax authorities.
2. What’s the maximum depreciation rate allowed?
In India, the Income Tax Act specifies maximum rates for different asset classes. For example, computers can be depreciated at 40%, while buildings typically have lower rates (5%-10%).
3. How does WDV affect my tax liability?
The WDV method typically results in higher depreciation expenses in early years, which reduces your taxable income and thus your tax liability in those years. However, this means lower depreciation (and thus higher taxable income) in later years.
4. Can I use different rates for different assets?
Yes, you can and should use different rates for different asset classes. The rate should reflect the actual usage pattern and economic life of each specific asset.
5. What happens if I sell an asset before it’s fully depreciated?
If you sell an asset before the end of its useful life, you’ll need to calculate the gain or loss on disposal by comparing the sale price with the net book value at the time of sale.
6. Is WDV method allowed for all types of assets?
While WDV is permitted for most depreciable assets, some assets like land (which doesn’t depreciate) or certain intangible assets may have different treatment. Always check the specific accounting standards applicable to your situation.
7. How do I calculate the depreciation rate?
The depreciation rate can be determined based on:
- The asset’s expected useful life
- Industry standards for similar assets
- Tax regulations in your jurisdiction
- The asset’s actual usage pattern
A common approach is to use a rate that would depreciate the asset to its salvage value over its useful life. For example, for a 5-year life with 10% salvage value, you might use a 40% rate.
Advanced Considerations
Partial Year Depreciation
When an asset is purchased or disposed of during the year, you’ll need to calculate depreciation for a partial year. The most common approaches are:
- Time proportion – Calculate based on months owned
- Half-year convention – Assume asset was owned for half the year
- Full year in year of acquisition – Some tax systems allow this
Change in Depreciation Rate
If you need to change the depreciation rate during an asset’s life (due to changed expectations about usage patterns), you should:
- Document the reason for the change
- Get approval if required by accounting standards
- Apply the new rate prospectively (not retrospectively)
- Disclose the change in financial statements
WDV for Intangible Assets
While WDV is more commonly used for tangible assets, it can also be applied to certain intangible assets like:
- Software licenses
- Patents and copyrights
- Customer lists
- Franchise agreements
The key consideration is whether the asset’s economic benefits are consumed more quickly in early years.
Conclusion
The Written Down Value method provides a more accurate reflection of how many assets actually lose value over time. By front-loading depreciation expenses, it better matches expenses with the economic reality of asset usage. However, the method requires careful calculation and consistent application to ensure compliance with accounting standards and tax regulations.
For business owners and accountants, understanding the WDV method is crucial for:
- Accurate financial reporting
- Effective tax planning
- Informed asset management decisions
- Compliance with accounting standards
Use the calculator above to experiment with different scenarios and see how changing the depreciation rate or useful life affects the depreciation schedule. For complex situations or high-value assets, consider consulting with a qualified accountant or tax professional.
