# Understanding the Declining Balance Method: Formula and Benefits

## What Is the Declining Balance Method?

The declining balance method is an accelerated way to record larger depreciation in an asset's early years. The system records smaller depreciation expenses during the asset's later years.

### Key Takeaways

*   The declining balance method accelerates depreciation by recording larger expenses during an asset's early years.  
    
*   This method is ideal for technology products that rapidly depreciate due to obsolescence.  
    
*   Unlike the straight-line method, declining balance leads to smaller depreciation expenses in later years.  
    
*   The double-declining method depreciates assets twice as quickly by doubling the rate of the declining balance method.  
    
*   Accelerated depreciation techniques can reduce taxable income early in an asset's life.

## Calculating Declining Balance Depreciation: A Step-by-Step Guide

Depreciation under the declining balance method is calculated with this formula:

$\begin{aligned} &\text{Declining Balance Depreciation} = CBV \times DR\\ &\textbf{where:}\\ &CBV=\text{current book value}\\ &DR=\text{depreciation rate (\%)}\\ \end{aligned}$  

Current book value is the asset's net value at the start of an accounting period. It's calculated by deducting the [accumulated depreciation](https://www.investopedia.com/terms/a/accumulated-depreciation.asp) from the cost of the fixed asset.

[Residual value](https://www.investopedia.com/terms/r/residual-value.asp) is the estimated salvage value at the end of the useful life of the asset.

The rate of depreciation is defined according to the estimated pattern of an asset's use over its useful life. The expense would be $270 in the first year, $189 in the second year, and $132 in the third year if an asset costing $1,000 with a salvage value of $100 and a 10-year life depreciates at 30% each year.

## Understanding the Insights of the Declining Balance Method

The declining balance method is also known as the reducing balance method. It's ideal for assets that quickly lose their value or inevitably become obsolete. This is classically true with computer equipment, cell phones, and other high-tech items that are generally useful earlier on but become less so as new models are brought to market. An accelerated method of depreciation ultimately factors in the phase-out of these assets.

> Employing the accelerated depreciation technique means there will be lesser taxable income in the earlier years of an asset's life.

The declining balance method contrasts with straight-line depreciation, which suits assets that lose value steadily.

The [straight-line depreciation method](https://www.investopedia.com/terms/s/straightlinebasis.asp) simply subtracts the salvage value from the cost of the asset and this is then divided by the useful life of the asset. The annual straight-line depreciation expense would be $2,000 ($15,000 minus $5,000 divided by five) if a company shells out $15,000 for a truck with a $5,000 salvage value and a useful life of five years.

## Comparing Declining Balance and Double-Declining Methods

It may signal that a company is using accelerated depreciation methods such as the [double-declining balance depreciation](https://www.investopedia.com/terms/d/double-declining-balance-depreciation-method.asp#:~:text=The%20double-declining%20balance%20depreciation%20method%20is%20an%20accelerated,depreciation%20each%20year%20over%20an%20asset%27s%20useful%20life%29.) method if it often recognizes large gains on sales of its assets, Net income will be lower for many years but this ultimately leads to a bigger gain when the asset is sold because book value ends up being lower than market value. Its sale could portray a misleading picture of the company's underlying health if the asset is still valuable.

## What Is Accumulated Depreciation?

Accumulated depreciation is total depreciation over an asset's life beginning with the time when it's put into use. Depreciation is typically allocated annually in percentages.

## How Does Depreciation Affect Taxes?

Depreciation lets a company deduct an asset's value decline, lowering taxable income. The company must own the asset and use it to generate income. Its anticipated service life must be for more than one year and it must have a determinable useful life expectancy.

## How Does the Double-Declining Balance Depreciation Method Work?

The double-declining method involves depreciating an asset more heavily in the early years of its useful life. A business might write off $3,000 of an asset valued at $5,000 in the first year rather than $1,000 a year for five years as with straight-line depreciation. The double-declining method depreciates assets twice as quickly as the declining balance method as the name suggests.

## The Bottom Line

The declining balance method is an accelerated depreciation technique that allows businesses to report larger depreciation expenses in the early years of an asset's life, which reduces taxable income during those years. This method is particularly effective for assets like technology products that quickly become obsolete.

While this approach results in smaller depreciation amounts in later years, it is advantageous for managing tax liabilities in the short term. Understanding the right depreciation method can significantly impact a business's financial statements and tax obligations. Businesses must consider the nature of their assets and financial strategy when selecting a depreciation method.
