Depreciation expense is one of the popular accounting methods used to allocate the cost of a tangible fixed asset over its useful life. Rather than recording the total cost of an asset purchase as an expense at once, depreciation systematically spreads the cost over the years the asset is expected to contribute economic benefits to the business. This allows companies to match the expense with the revenues generated by using the asset, adhering to the matching principle in accounting.
Key Takeaways
- Depreciation expense spreads the cost of a fixed asset over its useful life to match expenses with revenue.
- It is a non-cash expense reflecting the asset’s usage, wear, or obsolescence during a period.
- Various depreciation methods (straight-line, declining balance, SYD, units of production) allocate expense differently based on asset usage or strategy.
- Choosing a depreciation method depends on the asset type, business goals, tax rules, and financial reporting needs.
How Does Depreciation Expense Work?
Depreciation expense represents the reduction in value of an asset due to usage, wear and tear, or obsolescence during an accounting period. It's a non-cash charge, meaning it does not involve an actual outflow of cash at the time it is recorded. Instead, it reflects how much of the asset's value has been consumed.
Businesses use depreciation to reflect this usage on financial statements, which impacts profit and loss and tax calculations. Key factors in calculating depreciation include the asset's initial cost, its expected useful life, and estimated residual or salvage value at the end of its use.

Different Methods of Depreciation Expense
There are several methods that exist to calculate depreciation expense, each offering a different pattern of expense allocation:
- Straight-Line Method: The simplest and most common method, it evenly distributes the depreciable amount of an asset over its useful life using the formula:
Depreciation Expense=Cost of Asset−Salvage Value/ Useful Life
This Straight-Line method models an equal expense amount in each period.
- Declining Balance Method: An accelerated depreciation approach that records higher depreciation expenses in the earlier years of the asset's life and progressively less in later years. A common variant used is the Double Declining Balance method, which doubles the straight-line depreciation rate. The formula is:
Depreciation Expense=Book Value at Beginning of Year×2/Useful Life
- Sum-of-the-Years'-Digits (SYD): This method also accelerates depreciation by applying a decreasing fraction based on the sum of the years' digits of the asset’s life to the depreciable base.
- Units of Production Method:Calculates depreciation based on actual usage or production levels of the asset, making it ideal for assets whose wear depends on output rather than time.
Illustration Calculating Depreciation Expense
Suppose a company purchases machinery for ₹1,00,000 with an expected useful life of 10 years and a salvage value of ₹10,000. Using the straight-line method:
Depreciation Expense= ₹1,00,000−₹10,000/10= ₹9,000 per year
The company will record ₹9,000 as depreciation expense annually for 10 years, reflecting the asset's consumption over time.
Using the double declining balance method on the same asset, the first year's depreciation would be:
1,00,000×2/10=20,000
Subsequent years’ depreciation expenses decrease as they are calculated on the declining book value.
Conclusion
Depreciation expense is a vital concept in accounting that accurately assigns the cost of a fixed asset over its useful life, reflecting consumption and preserving the matching principle. Various methods of depreciation provide flexibility depending on the asset type, business needs, and financial strategy. Understanding depreciation helps businesses manage asset costs, financial reporting, and tax implications effectively.
