Welcome to the World of Depreciation!
Ever bought a brand-new smartphone and noticed that a year later, it’s not worth nearly as much as what you paid for it? That "loss in value" is exactly what we are looking at today, but from a business perspective. In Financial Accounting, we call this Depreciation.
By the end of these notes, you will understand how businesses account for the "wear and tear" of their big purchases (like machinery and delivery vans) so that their financial statements show a fair and honest picture. Don't worry if it seems a bit technical at first—we'll break it down step-by-step!
1. What is Depreciation?
Businesses buy Non-Current Assets (NCAs) like cars, computers, and machinery to help them make money over several years. Because these assets wear out or become outdated over time, we shouldn't record the entire cost as an expense in the first year. That wouldn't be fair to the years that follow!
Depreciation is the systematic allocation of the cost of an asset over its useful life. It’s the way we "spread" the cost of the asset to match the income it helps generate. This follows the Accruals (Matching) Concept.
Example: If a bakery buys a delivery van for \$10,000 and expects it to last for 5 years, depreciation is the way we record a portion of that \$10,000 as an expense in each of those 5 years.
Key Terms to Remember:
• Cost: How much you paid for the asset.
• Useful Life: How long the business expects to use the asset (not necessarily how long it physically lasts).
• Residual Value (or Scrap Value): What we think the asset will be worth at the end of its useful life.
• Depreciable Amount: The total amount we plan to "use up" \( (\text{Cost} - \text{Residual Value}) \).
• Carrying Amount (or Net Book Value): The value of the asset currently on the books \( (\text{Cost} - \text{Accumulated Depreciation}) \).
2. The Two Main Methods of Calculation
The ACCA FA syllabus focuses on two ways to calculate depreciation. The method a business chooses depends on how they expect to "consume" the asset's benefits.
Method A: The Straight-Line Method
This is the simplest method. We assume the asset wears out by the same amount every single year. It’s like a flat-rate tax on the asset's value.
The Formula:
\( \text{Annual Depreciation} = \frac{\text{Cost} - \text{Residual Value}}{\text{Useful Life}} \)
Sometimes, the exam might give you a percentage instead of years. In that case:
\( \text{Annual Depreciation} = (\text{Cost} - \text{Residual Value}) \times \% \)
Quick Tip: If the question says "20% straight line" and doesn't mention a residual value, just multiply the Cost by 20%!
Method B: The Reducing Balance Method
Some assets, like cars or computers, lose a lot of value in the first year and less as they get older. This method applies a fixed percentage to the Carrying Amount (what's left on the books) rather than the original cost.
The Formula:
\( \text{Annual Depreciation} = \text{Carrying Amount} \times \% \)
(Remember: \( \text{Carrying Amount} = \text{Cost} - \text{Depreciation already charged in previous years} \))
Common Mistake to Avoid: Never subtract the Residual Value before calculating Reducing Balance depreciation! The formula naturally moves the value toward the residual amount over time.
Key Takeaway:
Straight Line = Same amount of expense every year.
Reducing Balance = High expense in Year 1, getting smaller every year after.
3. Recording Depreciation (The Double Entry)
This is where many students get nervous, but there’s a simple trick. Think of it as two separate buckets. One bucket is the Expense (P&L) and the other is the Accumulated Depreciation (SFP) which "collects" all the depreciation over the years.
The Journal Entry:
Debit (Dr): Depreciation Expense (Income Statement/P&L)
Credit (Cr): Accumulated Depreciation (Balance Sheet/SFP)
Memory Aid: Use the DEAD CLIC rule. Expenses (Depreciation Expense) are always Debits when they increase. Accumulated Depreciation is a "Contra-Asset" (it reduces an asset), so it acts like a Liability and is a Credit.
Step-by-Step Process:
1. Calculate the depreciation for the current year only.
2. Debit the Depreciation Expense account with this year's figure.
3. Credit the Accumulated Depreciation account with this year's figure.
4. When preparing the Statement of Financial Position, subtract the total (accumulated) depreciation from the original cost of the asset.
4. Important Rules to Watch Out For
Pro-rata Depreciation:
If a business buys an asset halfway through the year, they might only charge depreciation for the months they actually owned it. If the policy is "monthly pro-rata," and you owned a van for 6 months, you only charge \( 6/12 \) of the annual depreciation.
Full Year in Year of Acquisition:
Some businesses have a policy of charging a full year's depreciation in the year they buy an asset, and none in the year they sell it. Read the exam question carefully to see which policy they use!
Did you know? Land is almost never depreciated. Why? Because unlike a tractor or a laptop, land doesn't "wear out" or have a limited useful life. In fact, it often goes up in value!
5. Summary and Quick Review
Quick Review Box:
• Depreciation spreads the cost of an asset to match income (Matching Concept).
• Straight Line: \( (\text{Cost} - \text{Residual}) / \text{Life} \).
• Reducing Balance: \( \text{Carrying Amount} \times \% \).
• Journal Entry: Dr Depreciation Expense, Cr Accumulated Depreciation.
• Carrying Amount: The value shown on the SFP \( (\text{Cost} - \text{Accumulated Depreciation}) \).
Don't worry if you find the Reducing Balance calculations a bit fiddly at first. Just remember: Subtract the old depreciation first, then multiply by the percentage! Keep practicing these calculations, and they will become second nature in no time.
