Some business assets, such as aging equipment and vehicles, have a financial journey marked by depreciation, meaning they lose value over time due to wear and tear or usage.

Therefore, understanding how assets accumulate depreciation and learning how to calculate these assets is fundamental within accounting.

What is accumulated depreciation?

Accumulated depreciation is an accounting term that refers to the cumulative reduction of an asset over time. In other words, it shows the entire depreciation cost documented for an asset since its purchase.

For example, let’s say a company purchases a delivery truck for $50,000. Over the next five years, the company records $10,000 of depreciation expense each year. After five years, the accumulated depreciation for the truck would be $50,000.

Assets that typically accumulate depreciation include buildings, vehicles, machinery, and equipment. These assets gradually lose value over time due to wear and tear, obsolescence, or other factors.

Accumulated depreciation is crucial for financial reporting and asset valuation since it provides insight into an asset’s true value and allows businesses to track its decrease in value over time.

Accumulated depreciation is vital for calculating depreciation expenses and determining the net book value of assets, so understanding how to enter it on a balance sheet is important.

Where is accumulated depreciation on a balance sheet?

Accumulated depreciation is usually under the fixed asset category, specifically as a credit balance deducted from the total cost of the property, plant, and equipment. This deduction provides a more accurate representation of the net value of the assets.

When presenting accumulated depreciation in the balance sheet, companies can either show it as a single credit balance under fixed assets or separately for each class of assets. This often depends on the size and complexity of the company’s asset base.

For example, a small manufacturing company may want to present accumulated depreciation separately for each class of assets to provide more detailed information. This allows them to better understand the depreciation for different types of assets and make more informed decisions regarding capital expenditures and asset replacements.

Accumulated depreciation is crucial for showing the actual value of a company’s assets on the balance sheet and accurately reflecting the business’s financial health.

Despite this amount being displayed close to assets on a balance sheet, is accumulated depreciation an asset?

Is accumulated depreciation a current asset?

The short answer is no, accumulated depreciation isn’t considered a current asset. To understand why, first examine the criteria for a current asset.

Current assets are expected to be converted into cash or used up within one year or one operating cycle, whichever is longer. This includes items such as cash, accounts receivable, and inventory.

Long-term or non-current assets are resources a company owns or controls that aren’t expected to be converted into cash or used up within one year of the balance sheet date. These long-term assets are subject to depreciation because they’re expected to benefit the company over an extended period.

Therefore, accumulated depreciation is a contra-asset account that reduces the value of a company’s long-term tangible assets. It’s not considered a current asset because it doesn’t meet the expected criteria of being converted into cash within one year.

Since contra-asset accounts typically have credit balances, it’s essential to know how accumulated depreciation is categorized.

Is accumulated depreciation a debit or credit?

Accumulated depreciation is a credit balance and is recorded as a contra-asset account, meaning it reduces the value of the fixed asset it’s associated with.

Therefore, you must credit the accumulated depreciation account and debit the fixed asset account to record accumulated depreciation, reflecting the decrease in the asset’s value and keeping your overall assets balanced.

As the fixed asset continues to depreciate over time, the accumulated depreciation balance will increase, reducing the asset’s carrying amount on the balance sheet. Once an asset’s carrying amount is zero, you can consider it fully depreciated.

Before zeroing out an asset, you must understand how to calculate accumulated depreciation.

How to calculate accumulated depreciation

There are several methods for calculating accumulated depreciation, each with its unique approach.

Here are the most common ways to calculate accumulated depreciation:

• Straight-line depreciation
• Declining balance depreciation
• The sum-of-years’-depreciation

Straight-line depreciation formula

The straight-line depreciation method is one of the most commonly used and simplest methods for calculating accumulated depreciation, as it offers a fairly straightforward process.

Here’s how to calculate the straight-line depreciation formula:

Straight-line Depreciation Expense = (Cost of the Asset – Estimated Salvage Value) ÷ Estimated Useful Life of an Asset

 

For example, a company acquires a piece of equipment for $120,000, expecting a salvage value of $25,000 after six years of use:

• Cost of the asset: $120,000
• Cost of the asset – Estimated salvage value: $120,000 – $25,000 = $95,000 (total depreciable cost)
• Useful life of an asset: 6 years
• Annual depreciation amount: $95,000 / 6 years = $15,833.33

Therefore, the company would depreciate the equipment by $15,833.33 annually for six years.

If you want to calculate the straight-line depreciation rate, the formula is:

Straight-line Depreciation Rate = Annual Depreciation Expense ÷ (Cost of the Asset – Salvage Value)

Divide $15,833.33 by $95,000 to get a straight-line depreciation rate of approximately 16.67%.

Straight-line depreciation is a favorite because it provides a consistent and transparent allocation of costs over an asset’s useful life for more upfront financial reporting.

Declining balance depreciation formula

Declining balance depreciation, or double declining balance depreciation (DDB), is a popular accounting method that systematically allocates an asset’s cost over its estimated useful life.

Unlike straight-line depreciation, this approach accelerates the recognition of depreciation expenses in the early years, reflecting the belief that assets depreciate more rapidly initially.

By applying a set rate to the diminishing book value, declining balance depreciation offers a realistic portrayal of an asset’s decreasing contribution to revenue over time, providing businesses with a valuable tool to record finances accurately.

Here’s how to calculate the declining balance depreciation formula…

Depreciation Expense = Beginning Year Book Value × Depreciation Rate

For example, an asset costs $30,000 with a salvage value of $3,000 and a useful life of 3 years.

• Cost of the asset/Year 1 beginning book value: $30,000
• Salvage value: $3,000
• Useful life: 3 years

You can then find the depreciation rate by dividing the useful life by 1 and multiplying that resulting number by 2:

Depreciation Rate = (1÷Useful Life) x 2

Using the example above, the depreciation rate will look like…

Depreciation rate = (1÷3) x 2 = 66.67% or 2/3

Now that you’ve determined this rate, you can plug these numbers into the depreciation expense formula to determine your declining balance depreciation over a three-year period…

Year 1

Depreciation Expense (Year 1) = Year 1 beginning book value x Depreciation Rate

Depreciation Expense (Year 1) = $30,000 x (⅔) = $20,000

The depreciation expense is $20,000 in the first year; the asset will depreciate by $20,000.

Before calculating depreciation expenses for the following years, you’ll need to subtract the previous year’s beginning book value by its depreciation expense to determine the beginning book value for the next year:

Beginning book value (Year 2) = Beginning Book Value (Year 1) – Depreciation Expense (Year 1)

Using the figures from the example above, this formula will look like…

Beginning Book Value (Year 2) = $30,000 – $20,000 = $10,000

So, the book value at the end of the first year of depreciation is $10,000. You can now plug this figure into the depreciation expense formula for the second year.

Year 2

Depreciation Expense (Year 2) = Beginning Book Value (Year 2) x Depreciation Rate

Depreciation Expense (Year 2) = $10,000 x (⅔) = $6,666.67

The depreciation expense is $6,666.67 in the second year; the asset will depreciate by $6,666.67.

Then determine the beginning book value for the third year…

Beginning Book Value (Year 3) = Beginning Book Value (Year 2) – Depreciation Expense (Year 2)

Beginning Book Value (Year 3) = $10,000 – $6,666.67 = $3,333.33

Year 3

Depreciation Expense (Year 3) = Beginning Book Value (Year 3) x Depreciation Rate

Depreciation Expense (Year 3) = $3,333.33 x (⅔) = $2,222.22

Book Value (End of Year 3) = Beginning Book Value (Year 3) – Depreciation Expense (Year 3)

Book Value (End of Year 3) = $3,333.33 – $2,222.22 = $1,111.11

This completes the declining balance depreciation calculations for the 3-year period. The process continues until the book value reaches the salvage value or the end of the useful life.

This company determined the asset had a useful life of three years, meaning that based on factors such as wear and tear, technological obsolescence, or changes in market demand, it expects the asset to be most economically valuable during those three years.

After that period, the asset may become less efficient, more prone to breakdowns, or outdated, making it less economically viable to keep in operation.
​

Sum-of-the-years’-digits depreciation formula

The Sum-of-the-Years’-Digits (SYD) approach is an expedited technique to calculate an asset’s depreciation.

In the SYD method, the expected lifespan of the asset is considered, and the digits for each year are added together. Subsequently, each digit is divided by this sum. The resulting percentages are then employed to determine the annual depreciation, starting with the highest percentage applied in the first year.

The SYD method is logical when an asset experiences a significant decline in value early in its useful life. Technology and machinery equipment are common examples of assets with a rapid decline in value in the earlier years of their useful life.

For example, if an asset is anticipated to last four years, the sum-of-the-years’-digits would be calculated by adding 4 + 3 + 2 + 1, resulting in 10. This four-year lifespan calculated using the SYD method would follow this depreciation schedule:

Year 1: 4/10 = 40% depreciation
Year 2: 3/10 = 30% depreciation
Year 3: 2/10 = 20% depreciation
Year 4: 1/10 = 10% depreciation

This SYD method results in higher depreciation amounts in the earlier years of an asset’s life, with the amounts decreasing in the later years.

Understanding the different methods of calculating accumulated depreciation is essential for accurately reflecting an asset’s value over time. While each formula has its nuances and considerations, you should choose the one that best fits your business assets and stick with it for reporting consistency.

Understanding the impact of accumulated depreciation on a balance sheet

Accumulated depreciation shows how assets naturally wear down or become outdated over time. By spreading the cost of an asset over its useful life, depreciation ensures that expenses align with the revenue generated, offering a transparent representation of profitability. This practice allows stakeholders to understand the true value of assets over time.

Depreciation also often comes with tax advantages, enabling businesses to deduct a portion of an asset’s cost and effectively manage their tax liabilities.

Understanding accumulated depreciation is pivotal for gaining insight into a company’s financial health and maintaining a transparent representation of assets and how their value may decline over time.
