Short Answer
Depreciation can be calculated using different methods depending on the nature of the asset and business needs. The most common methods are the straight-line method and the written down value method.
Other methods include the units of production method and the sum of years’ digits method. Each method calculates depreciation in a different way but aims to spread the cost of an asset over its useful life.
Detailed Explanation:
Methods of depreciation
Straight line method
The straight-line method is the simplest and most commonly used method of depreciation. Under this method, an equal amount of depreciation is charged every year over the useful life of the asset.
For example, if an asset costs ₹1,00,000 and its useful life is 10 years, then ₹10,000 will be charged as depreciation each year. This method is easy to understand and provides a fixed expense every year.
It is suitable for assets that are used evenly over time, such as buildings and furniture.
Written down value method
The written down value method is also known as the reducing balance method. In this method, depreciation is calculated on the remaining value of the asset each year.
As a result, the amount of depreciation is higher in the earlier years and decreases over time. This method is suitable for assets like machinery and vehicles that lose more value in the beginning.
For example, if an asset has a value of ₹1,00,000 and depreciation is charged at 10%, the first year depreciation will be ₹10,000. In the next year, depreciation will be calculated on ₹90,000, and so on.
Units of production method
Under this method, depreciation is based on the usage or output of the asset. Instead of time, it depends on how much the asset is used.
For example, a machine may be expected to produce 1,00,000 units in its lifetime. Depreciation is calculated based on the number of units produced each year.
This method is useful for machines and equipment where usage varies each year.
Sum of years digits method
This method is another accelerated method of depreciation. It charges higher depreciation in the early years and lower in later years.
The total useful life of the asset is added in the form of digits. Then depreciation is calculated based on these digits. This method reflects the fact that many assets lose more value in the beginning.
Annuity method
In the annuity method, depreciation is calculated by considering both the cost of the asset and the interest on capital invested. It assumes that the asset is like an investment.
This method is more complex and is used in special cases where interest plays an important role.
Importance of choosing correct method
Accurate profit calculation
Different methods give different depreciation amounts. Choosing the correct method helps in calculating accurate profit.
Proper asset valuation
The method selected affects how the asset value is shown in the balance sheet. It helps in presenting the correct financial position.
Suitable for different assets
Different assets require different methods. For example, machinery may use the written down value method, while buildings may use the straight-line method.
Conclusion
There are various methods of depreciation such as straight-line, written down value, units of production, sum of years’ digits, and annuity method. Each method has its own way of calculating depreciation. Choosing the right method ensures accurate accounting, proper asset valuation, and correct financial reporting.
