When businesses or individuals invest in assets such as equipment, vehicles, or machinery, they must account for their depreciation over time. Depreciation reflects the loss of value of an asset as it ages. The reducing-balance method is one such way of calculating depreciation, and it can be a powerful tool for businesses to manage their finances more effectively. In this article, I will take a deep dive into the reducing-balance method, explain how it works, compare it with other depreciation methods, and provide examples to help you understand the process.

What is the Reducing-Balance Method?
The reducing-balance method, also known as the declining balance method, is a way of calculating depreciation that allows a higher depreciation charge in the earlier years of an asset’s useful life and progressively lower charges in later years. This approach recognizes that some assets lose value more rapidly in the beginning of their useful life than later on. The main idea is that the asset is assumed to provide more utility or value at the beginning, and as it ages, its depreciation decreases.
How Does the Reducing-Balance Method Work?
The formula for calculating depreciation using the reducing-balance method is:
D = B \times rWhere:
- D is the depreciation expense for the period,
- B is the book value of the asset at the start of the period (which is the cost of the asset minus the accumulated depreciation),
- r is the depreciation rate (expressed as a percentage).
In the reducing-balance method, the depreciation rate is applied to the book value, which decreases over time as depreciation accumulates. The depreciation expense is higher in the initial years and decreases over time.
Step-by-Step Calculation Process
To better understand how the reducing-balance method works, let’s walk through a simple example.
Example 1: Depreciation of a Car Using the Reducing-Balance Method
Imagine you purchase a car for $20,000, and it has a useful life of 5 years. You decide on a depreciation rate of 20% per year. To calculate depreciation using the reducing-balance method, you would follow these steps:
- Year 1:
- Book value at the start of Year 1: $20,000
- Depreciation expense = $20,000 × 20% = $4,000
- Book value at the end of Year 1 = $20,000 – $4,000 = $16,000
- Year 2:
- Book value at the start of Year 2 = $16,000
- Depreciation expense = $16,000 × 20% = $3,200
- Book value at the end of Year 2 = $16,000 – $3,200 = $12,800
- Year 3:
- Book value at the start of Year 3 = $12,800
- Depreciation expense = $12,800 × 20% = $2,560
- Book value at the end of Year 3 = $12,800 – $2,560 = $10,240
- Year 4:
- Book value at the start of Year 4 = $10,240
- Depreciation expense = $10,240 × 20% = $2,048
- Book value at the end of Year 4 = $10,240 – $2,048 = $8,192
- Year 5:
- Book value at the start of Year 5 = $8,192
- Depreciation expense = $8,192 × 20% = $1,638.40
- Book value at the end of Year 5 = $8,192 – $1,638.40 = $6,553.60
As you can see, the depreciation expense is higher in the early years and decreases as the asset’s book value decreases.
Comparison with Other Depreciation Methods
There are several ways to calculate depreciation, and the reducing-balance method is just one of them. It’s useful to compare this method with other common methods, such as straight-line depreciation and sum-of-the-years’-digits (SYD).
| Method | Depreciation Expense Pattern | Example of Asset Depreciation | Best Used For |
|---|---|---|---|
| Reducing-Balance Method | Higher depreciation in early years, lower in later years | Car, Machinery | Assets that lose value quickly in early years |
| Straight-Line Method | Equal depreciation each year | Buildings, Furniture | Assets that lose value evenly over time |
| Sum-of-the-Years’-Digits | Higher depreciation in early years, steeper decline than reducing balance | Technology equipment, Vehicles | Assets with a higher initial utility |
In the straight-line method, the depreciation expense remains constant throughout the asset’s useful life, which differs from the reducing-balance method, where depreciation expenses decline over time. The sum-of-the-years’-digits method, like the reducing-balance method, accelerates depreciation, but it does so more rapidly in the initial years than the reducing-balance method.
When Should You Use the Reducing-Balance Method?
The reducing-balance method is particularly useful for assets that lose value quickly. This could include vehicles, computers, or machinery, which become obsolete or wear out faster in the initial years. The method is also used in tax accounting to maximize depreciation deductions early on, which can be beneficial for businesses looking to reduce taxable income in the short term.
Here are a few factors that may influence your decision to use the reducing-balance method:
- Asset Type: Assets that lose value faster in the early years, such as technology and vehicles, are better suited for the reducing-balance method.
- Tax Considerations: The higher depreciation in the early years can help reduce taxable income in the initial years of an asset’s life, which can be a tax advantage.
- Financial Strategy: Companies looking to reduce expenses and increase cash flow in the early years may prefer this method.
Benefits of the Reducing-Balance Method
- Accelerated Depreciation: The main benefit of the reducing-balance method is that it allows for higher depreciation in the earlier years. This can be advantageous for businesses seeking to lower their taxable income in the short term.
- Reflects Reality: In many cases, assets lose their value more rapidly in the first few years. The reducing-balance method more accurately reflects the actual wear and tear on assets, especially for technology or vehicles.
- Financial Flexibility: By recognizing higher depreciation earlier, businesses can reinvest savings into other areas of their operations.
Drawbacks of the Reducing-Balance Method
- Complexity: Compared to the straight-line method, the reducing-balance method can be more difficult to calculate, especially for assets with a long useful life.
- Lower Depreciation in Later Years: Since depreciation is reduced over time, this method may not provide enough depreciation for older assets in later years, potentially leading to higher taxes in the long run.
- Book Value Fluctuations: The book value decreases faster in the initial years, which may make it harder to track the asset’s actual market value.
Key Considerations
- Depreciation Rate: The choice of the depreciation rate significantly impacts the calculation of depreciation under the reducing-balance method. Generally, the rate is set as a percentage of the asset’s cost or its expected residual value. In some cases, the rate is determined by industry standards.
- Residual Value: While the reducing-balance method typically doesn’t take the residual value into account when calculating annual depreciation, it does ensure that the asset’s book value doesn’t fall below its residual value.
- Tax Impact: Since businesses can accelerate depreciation with the reducing-balance method, they can reduce their taxable income in the short term. However, this comes at the cost of lower depreciation deductions in the later years.
Conclusion
The reducing-balance method is an effective way of calculating depreciation for certain types of assets, especially those that lose value quickly in the early years. While it may not be suitable for all assets, it provides businesses with an opportunity to maximize depreciation deductions early on, which can help reduce taxable income and improve cash flow. When deciding whether to use this method, it’s essential to consider the asset type, tax implications, and long-term financial strategy. If used correctly, the reducing-balance method can offer significant advantages for managing assets and improving financial performance.
