In the world of corporate accounting, expenses are not always about cash leaving a bank account. Instead, one of the most significant costs on a company’s income statement is often a non-cash item known as depreciation expense. Understanding this concept is vital for any business owner or accountant who wants to reflect the true cost of operations. Essentially, it is the process of allocating the cost of a tangible asset over the years it is used.
By recording depreciation expense, a business follows the “matching principle.” Consequently, it ensures that the expenses incurred to generate revenue are recorded in the same period as that revenue. Without this, your financial statements would show a massive loss in the year you buy equipment and artificial profits in the years that follow. This article will provide a deep dive into how this expense works, provide clear examples, and show you the exact journal entries required, following the core principles established in our pillar guide depreciation.
What Exactly is Depreciation Expense?
Initially, we must define what this expense represents. Depreciation expense is the allocated portion of the cost of a fixed asset that is “consumed” or “used up” during an accounting period. Because assets like machinery, vehicles, and buildings wear out or become technologically obsolete, their value must be reduced systematically.
Furthermore, it is important to remember that depreciation expense is a non-cash charge. You do not write a check to “Depreciation” every month. Rather, the cash was already spent when the asset was purchased. Therefore, this expense is used to lower the “book value” of the asset while providing a tax deduction. To understand which items in your inventory qualify for this treatment, refer to our detailed what is depreciating assets.
The Core Components of the Calculation
Before you can record a journal entry, you must calculate the expense accurately. To do this, you need three specific pieces of information that also form the basis of your gross fixed assets.
The Total Asset Cost
This is not just the sticker price. Instead, it includes everything spent to get the asset ready for use. For instance, it includes shipping, insurance during transit, and professional installation fees. As a result, the “cost” is often significantly higher than the original invoice.
The Salvage Value
Also known as residual value, this is what you expect the asset to be worth at the end of its useful life. If you plan to scrap a machine for parts, that scrap value must be subtracted from the total cost before calculating the annual expense.
The Useful Life
This is the estimated number of years the asset will be productive. Because technology moves fast, the useful life might be shorter than the physical life of the machine. Consequently, managers must be realistic when setting this timeline to avoid financial discrepancies later.
Straight-Line Depreciation Expense Example
The straight-line method is the most common way to calculate this expense. Essentially, it spreads the cost of an asset evenly across its life.
The Example Scenario
Imagine a company buys a high-capacity industrial oven for $55,000. They pay $5,000 for installation, making the total cost $60,000. They expect the oven to last for 5 years and have a salvage value of $10,000.
The Calculation
-
Depreciable Base: $60,000 – $10,000 = $50,000.
-
Annual Depreciation Expense: $50,000 / 5 years = $10,000 per year.
By using this simple formula, the company will record a $10,000 expense every year for five years. This consistency makes budgeting and financial forecasting much easier, as seen in our depreciation example.
Recording the Journal Entry
Once the calculation is finished, the next step is the accounting record. Recording a depreciation journal entry requires two specific accounts to keep the balance sheet in check.
The Debit: Depreciation Expense
You debit the depreciation expense account. Consequently, this increases the expenses on your income statement and reduces your taxable net income. This is the primary driver for understanding tax depreciation methods.
The Credit: Accumulated Depreciation
Instead of crediting the asset account directly, you credit a “contra-asset” account called accumulated depreciation. By doing so, you preserve the original cost of the asset on the balance sheet while showing how much of it has been “used up” over time. For more advanced recording techniques, see how to calculate accumulated depreciation.
The Journal Entry Format
For the example above, the annual entry would look like this:
-
Debit: Depreciation Expense … $10,000
-
Credit: Accumulated Depreciation … $10,000
Impact on the Three Financial Statements
Understanding where the depreciation expense goes is crucial for holistic asset management. Initially, it may seem like a minor entry, but it touches every part of your reporting.
The Income Statement
As mentioned, the expense appears here to reduce your profit. However, it does not affect your EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization), which is why many investors prefer that metric.
The Balance Sheet
The accumulated depreciation account grows here. This account is subtracted from your gross fixed assets to arrive at the “Net Book Value.”
The Cash Flow Statement
Since depreciation is a non-cash expense, it is added back to the net income in the operating activities section. As a result, it actually increases your “Cash from Operations,” even though it technically lowered your “Net Income.”
Accelerated Depreciation Expense and Journaling
In contrast to the straight-line method, some businesses prefer accelerated methods like the Double Declining Balance (DDB).
Why Use Accelerated Methods?
Because some assets lose most of their value in the first two years, it makes sense to record a higher expense early on. As a result, the company gets a larger tax break when the asset is newest. You can compare these strategies in our guide depreciation method comparison.
The Accelerated Journal Entry
Using the oven example, the first-year expense under DDB might be $24,000 instead of $10,000.
-
Debit: Depreciation Expense … $24,000
-
Credit: Accumulated Depreciation … $24,000
Depreciation Expense vs Accumulated Depreciation
It is a common mistake for non-accountants to confuse these two terms. Initially, they may seem interchangeable, but they have very different lifespan behaviors.
Temporary vs Permanent
Depreciation expense is a “temporary” account. It resets to zero at the end of every fiscal year. Essentially, it tells you the cost for that specific year.
Cumulative Tracking
Accumulated Depreciation is a “permanent” account. It continues to build up year after year. By looking at this account, you can see the total value lost since the day the asset was purchased. Mastering this difference is key to how to calculate accumulated depreciation.
Common Errors in Recording Depreciation Expense
Despite being a standard process, errors occur frequently, leading to audit failures. Therefore, a rigorous check is necessary.
Forgetting the “Placed in Service” Date
Sometimes, companies start depreciating an asset the day they pay for it. However, the correct rule is to start when the asset is ready and available for use. If a machine sits in a warehouse for three months before being installed, you cannot record depreciation for that period.
Exceeding the Salvage Value
One common mistake is continuing to record depreciation after the book value has hit the salvage value. If you do this, your asset value becomes negative on the books. Consequently, you must monitor your accumulated depreciation totals with absolute care.
The Role of Technology in Journaling
In the past, accountants had to manually calculate every entry. Now, modern software has transformed this into a one-click task.
Automation and Accuracy
Modern EAM (Enterprise Asset Management) systems can be programmed with the cost and life of every depreciating asset. By doing so, the software generates the journal entries automatically every month. This eliminates the risk of “fat-finger” errors in your general ledger.
Real-time Financial Visibility
With automated systems, your balance sheet is updated in real-time. You can see your gross fixed assets and net book values instantly. Ultimately, this allows for faster decision-making when it’s time to retire an old machine and invest in new capital goods.
Disposal and the Final Journal Entry
Eventually, every asset reaches the end of its journey. When you sell or scrap an asset, the depreciation expense story ends with a “disposal entry.”
Closing the Loop
When you get rid of an asset, you must remove both the original cost and the accumulated depreciation from your books. Initially, you debit Accumulated Depreciation to reset it and credit the Asset account to remove it.
Recording the Outcome
If you sell the asset for more than its book value, you record a “Gain on Disposal.” Conversely, if you sell it for less, you record a “Loss.” By doing this, you ensure your final financial statement reflects the true economic outcome of the asset lifecycle, as detailed in depreciation.
FAQ
Is depreciation expense a cash outflow?
No, it is a non-cash expense. The money was spent when you bought the asset. Depreciation is just how you “report” that cost over time.
Why do we credit “Accumulated Depreciation” instead of the Asset?
By using a contra-asset account, we can always see the original cost of the asset on the balance sheet for audit purposes.
When does depreciation expense stop?
It stops when the asset is sold, scrapped, or when the “Book Value” equals the “Salvage Value.”
What is the difference between an expense and a “Depreciating Asset”?
Read our Explanation: What Is Depreciating Assets? to see how a long-term resource is treated differently than a standard office supply.
