Every business has fixed assets—computers, office furniture, machinery, or company cars—that serve the business over an extended period. 

In accounting, the matching principle says we should record expenses in the same period as the revenue they help generate. If we were to deduct the full cost of these assets immediately, it would violate this principle by showing a large expense in the first year and none thereafter, even though the asset continues to be used. This makes the company’s finances look uneven. Depreciation solves this by spreading the cost of the asset over its useful life.

As a CFO or finance leader, you are responsible for ensuring that asset values are correctly reflected in your company’s books. In this blog, we’ll walk you through the fundamentals of depreciation accounting entry. 

Let’s begin by diving into what depreciation means and why it matters for your business.

What is Depreciation in Accounting?

What is Depreciation in Accounting?

Depreciation is when an asset loses value over time due to wear and tear or use. Instead of recording the full cost of an asset upfront, you spread the cost over its useful life. This prevents a big financial hit in a single year and instead records a portion of the cost each year as depreciation expense.

Example:
If you buy machinery for SAR 20,000 and plan to use it for 10 years, you would record SAR 2,000 annually as a depreciation expense.

Why it Matters:

  • Reflects the true value of assets in financial records.
  • Ensures compliance with accounting standards.
  • Provides a clearer picture of business expenses.

In Saudi Arabia, proper depreciation accounting also helps businesses meet Zakat, Tax, and Customs Authority (ZATCA) requirements, particularly under VAT and tax filing rules. Incorrect depreciation can lead to fines or issues in financial reporting. The process starts with creating a depreciation accounting entry.

What is the Accounting Entry for Depreciation?

A depreciation journal entry records the decrease in an asset's value over time. According to the matching principle in accounting, expenses should match the revenue they help generate. 

In the journal entry, you debit the depreciation expense account and credit the accumulated depreciation account. This ensures the asset’s cost is correctly reflected in your financial statements.

Suppose your company purchases office furniture for SAR 50,000 with an expected useful life of 5 years. Instead of recording the entire cost immediately, you allocate SAR 10,000 annually (SAR 50,000 ÷ 5 years) as depreciation. The journal entry for the first year would be:

Debit: Depreciation Expense SAR 10,000

Credit: Accumulated Depreciation SAR 10,000

To better understand depreciation, let’s distinguish between accumulated depreciation and depreciation expense. 

Understanding Accumulated Depreciation vs. Depreciation Expense

Both play distinct yet interconnected roles in financial reporting. Here’s how they differ:

Accumulated Depreciation vs. Depreciation Expense
Aspect Accumulated Depreciation Depreciation Expense
Definition The total depreciation recorded for an asset since it was put into use. The depreciation is allocated to a single reporting period, like a month or year.
How It’s Reported Shown as a credit on the balance sheet, reducing the value of fixed assets. Shown as a debit on the income statement, reducing net income.
Tax Impact Used to calculate the adjusted value of the asset for tax purposes if it’s sold. Used as a deduction to lower taxable income for the reporting period.
When It Ends Reversed (removed) when the asset is sold or no longer in use. Stops are recorded when the asset is sold or is no longer in use.

With a clear understanding of these concepts, let’s now explore the benefits of depreciation accounting.

Key Benefits of Depreciation Accounting

Key Benefits of Depreciation Accounting

Here are the key benefits of depreciation accounting entry:

  • Accurate Financial Reporting: Ensures your financial statements reflect the true value of assets and comply with accounting standards.
  • Tax Benefits: Depreciation helps businesses lower taxable income by allowing them to deduct depreciation expenses.
  • Asset Replacement Planning: Helps plan for future asset replacements by spreading costs over time.

Errors in depreciation accounting lead to misstated financials, higher tax liabilities, and missed investment opportunities. HAL ERP simplifies the process for you, ensuring accuracy and compliance at every step.

Let’s look at the different methods of calculating depreciation and how they impact your journal entries.

Common Depreciation Methods and Their Impact on Journal Entries

Common Depreciation Methods and Their Impact on Journal Entries

There are several methods for calculating depreciation, each impacting how depreciation is recorded in your journal entries. Let’s look at the most common methods:

1. Straight-Line Depreciation

The straight-line method is the simplest and most commonly used. It spreads the depreciation evenly over the asset’s useful life. Each year, the same amount of depreciation is recorded until the asset is fully depreciated.

Formula:

Depreciation Expense per Year = (Cost of Asset -Salvage Value)Useful Life 

For example, if machinery costs SAR 20,000 and is expected to last for 10 years, you would record SAR 2,000 in depreciation each year (SAR 20,000 ÷ 10 years). The journal entry for this would look like:

Journal Entry:

  • Debit: Depreciation Expense SAR 2,000
  • Credit: Accumulated Depreciation SAR 2,000

2. Double-Declining Balance Method

This method records more depreciation in the earlier years of an asset’s life and less in the later years. The asset loses value faster when it’s new.

Formula:

Depreciation Expense = 2 × (Book Value at Beginning of Year × Depreciation Rate)

For example, if machinery costs SAR 20,000 and the first-year depreciation is calculated at 20%, the journal entry for the first year would be:

Journal Entry:

  • Debit: Depreciation Expense SAR 4,000
  • Credit: Accumulated Depreciation SAR 4,000

3. Units of Production Depreciation

This method is based on how much the asset is used. It’s ideal for machines or equipment where usage varies each year.

Formula:

Depreciation Expense per Unit = (Cost of Asset -Salvage Value)Total Units Expected to be Produced

For instance, if a machine produces 10,000 units in its first year and 5,000 units in its second year, the depreciation recorded will vary based on the actual usage. The formula used for this method is:

Each method affects how much depreciation you record and how it appears in your financial statements. The choice of method depends on the type of asset and how it’s used.

Now that we’ve explored journal entries and their importance, let’s dive into the steps involved in calculating depreciation.

How Do You Calculate Depreciation?

Calculate Depreciation

When you purchase an asset, its original cost is recorded in the asset account on the balance sheet. At the end of each accounting period, a depreciation journal entry is made as part of the routine adjustments.

To calculate depreciation, you need four key details:

Once you have these details, you can calculate the depreciation expense for the asset. The formula for Depreciation:

Depreciable Amount = Cost - Residual Value

(Salvage value is often assumed to be zero for simplicity.)

Using these details, you can calculate depreciation for any asset and accurately record it in your accounts. Let’s see how it works. 

How to Record Depreciation Journal Entries

Once you have calculated depreciation, you’ll need to record it in your accounting system. Here’s the step-by-step process:

Step 1: Collect Necessary Data

Before recording depreciation, ensure you have the following details:

  • Cost of the Asset: The initial purchase price, including shipping and installation costs.
  • Useful Life: The estimated duration for which the asset will provide value.
  • Salvage Value: The expected residual value of the asset at the end of its useful life.
  • Depreciation Method: Choose from methods such as straight-line, declining balance, or units of production.

Step 2: Choose a Depreciation Method

The method you choose to calculate depreciation depends on the type of asset and how it is used. As mentioned before, here are the common methods: 

  • Straight-Line Method: Spreads depreciation evenly over the asset’s useful life.
  • Declining Balance Method: Applies more depreciation in the early years.
  • Units of Production Method: Bases depreciation on how much the asset is used

Step 3: Calculate Depreciation Expense

Using the chosen method, calculate the annual depreciation expense. For example, using the straight-line method:

Formula: Depreciation Expense = (Cost of Asset -Salvage Value)Useful Life 

Step 4: Create the Depreciation Journal Entry

Record the depreciation in your accounting system by using two accounts:

  • Debit: Depreciation Expense (reflects the cost of using the asset in the current period).
  • Credit: Accumulated Depreciation (reduces the asset’s value over time).

Example Entry:

Date Account Debit Credit
Jan 1 Depreciation Expense SAR 4,500
Accumulated Depreciation SAR 4,500

Step 5: Post the Entry in the Ledger

Post the journal entry in your accounting software or manual ledger at the end of each period: 

  • Update the Depreciation Expense account in the income statement.
  • Update the Accumulated Depreciation account under the asset section in the balance sheet.

Step 6: Adjust the Asset’s Book Value

After recording, subtract the accumulated depreciation from the asset’s original cost to determine its book value.

To better understand the process, let’s look at an example of a depreciation journal entry. 

Depreciation Expense Journal Entry Example

Suppose your business purchases office furniture for SAR 45,000 on January 1. The furniture has a useful life of 5 years and a SAR 7,000 salvage value. You’ve chosen the straight-line depreciation method, which spreads the cost evenly over the asset's useful life.

First, calculate the annual depreciation expense using the straight-line formula:

Depreciation Expense = (Cost of Asset -Salvage Value)Useful Life

    = (45,000 − 7,000)5 years = SAR 7,600 per year

Now that you have the annual depreciation, here’s how you record the journal entry at the end of the year:

Date Account Debit Credit
Dec 31 Depreciation Expense SAR 7,600
Accumulated Depreciation SAR 7,600

Impact of Depreciation Accounting Entry on Financial Statements

Impact of Depreciation Accounting Entry on Financial Statements

Depreciation has a significant impact on various financial statements. Let’s explore how it affects each one:

  • Income Statement: Depreciation is recorded as an expense, reducing your company’s profits. Although it is a non-cash expense, it provides a more accurate view of profitability.
  • Balance Sheet: The accumulated depreciation account reduces the asset’s book value. This ensures your balance sheet reflects the true, depreciated value of assets.
  • Cash Flow Statement: Since depreciation is a non-cash expense, it’s added back in the operating activities section to calculate actual cash flow.

Understanding these impacts helps you make informed decisions about asset management, tax planning, and financial forecasting.

Now, let’s explore common mistakes to avoid when handling depreciation.

Common Mistakes in Depreciation Accounting Entry

Even small mistakes in depreciation can lead to significant errors in financial reporting. Here are some common challenges and how to avoid them:

i) Recording Depreciation in the Wrong Period
Solution:
Record depreciation at the end of each accounting period. Set reminders or keep a schedule. 

ii) Using the Wrong Depreciation Method
Solution:
Choose the right method for each asset. Consult your accountant if unsure.

iii) Incorrectly Estimating Useful Life or Salvage Value

Solution: Carefully estimate the asset's useful life and salvage value. Update them if needed.

iv) Not Updating Depreciation Schedules
Solution:
Keep schedules updated for new or disposed assets.

v) Forgetting to Adjust for Accumulated Depreciation
Solution:
When selling or disposing of an asset, adjust the accumulated depreciation by debiting it and crediting the asset account.

vi) Misclassifying Accounts
Solution:
Double-check that depreciation is correctly recorded.

vii) Switching Depreciation Methods Without Documentation

Solution: Always document and stick to one method.

Avoiding these mistakes will help keep your financial records accurate. To make depreciation accounting entry even easier, consider using tools that automate and streamline the process, like HAL ERP.
