Introduction
When it comes to the topic of calculating the depreciation value of an asset of a business in a competitive industry, there are numerous methods that are frequently used in order to conduct the calculation. Straight Line method is one such method.
The straight line method of depreciation is an especially helpful and effective method of calculating the depreciable value of any particular asset with regards to its acquiring cost and potential salvage value. Therefore, this is a crucial method that is often incorporated among firms worldwide.
Straight Line Method of Depreciation
The process of straight line depreciation involves the cost of acquisition of an asset as well as its potential future salvage value in years to come, as has been stated above. So, in order to expand on the topic of the depreciation method of Straight Line, these two aspects shall be understood first.
Since the straight line depreciation formula involves the cost of an asset, the asset that is being positioned in the market which can potentially yield a profit to its company will inevitably face a depreciation in its value in the market, with few rare exceptions. Therefore, the potential salvage value, i.e., the value of the asset in terms of its monetary value in the market in the future is utilized in this method to narrow down the depreciation value of the asset in the market with respect to the years of consideration.
Therefore, in order to further this discussion about this particular method of straight line depreciation, the formula that has been established in relation to this method has hereby been stated.
Straight Line Method of Depreciation Formula
As stated above, the straight line method is dependent entirely on an asset’s acquisition cost (the cost of the asset with which the asset has been purchased or sold in the market), and the salvage value which is the value at which the asset is presently or expectedly being sold or purchased in the market.
Therefore, the straight line method formula has been penned in accordance with the contributing factors of the method. The formula is hence derived by the difference between the salvage value of the asset in the market and the initial cost of acquisition of the asset. The resulted difference is the depreciation value of the asset.
The straight line depreciation equation is:
Depreciation Expense = \[\frac{\text{Cost of Fixed Asset - Salvage Value}}{\text{Useful Life }}\]
Straight Line Projection
Since a large part of the method of calculating the depreciating value of an asset in a market involves the projection of the annual depreciation formula of the asset’s value, it is imperative to understand the method of Straight line forecasting.
Straight Line projection or forecasting refers to the practice of gaining a thorough understanding of a business’ future potential revenue growth. The estimation that is required for this method is in alliance with the linear method of depreciation.

FAQs on Straight Line Depreciation Method Explained
1. What is the Straight Line Method (SLM) of depreciation as per the CBSE Class 11 Accountancy syllabus?
The Straight Line Method is a way to calculate depreciation where the cost of a tangible asset is reduced by a uniform amount each year over its useful life. The core principle is that the asset provides equal utility or benefit throughout its lifespan, so the depreciation expense charged to the Profit and Loss Account remains constant every year.
2. What is the formula to calculate the annual depreciation expense using the Straight Line Method?
The formula for calculating the annual depreciation expense under the Straight Line Method is:
Depreciation Expense = (Cost of Asset - Estimated Salvage Value) / Estimated Useful Life of the Asset
- Cost of Asset: The original purchase price plus any costs incurred to bring the asset into use (e.g., installation charges).
- Salvage Value: The estimated residual or scrap value of the asset at the end of its useful life.
- Useful Life: The estimated period for which the asset is expected to be used by the business.
3. Can you explain how to calculate straight-line depreciation with a simple example?
Certainly. Imagine a company buys a machine for ₹1,20,000. It estimates the machine will have a useful life of 10 years and a salvage value of ₹20,000 at the end of that period.
Using the formula:
- Cost of Asset: ₹1,20,000
- Salvage Value: ₹20,000
- Useful Life: 10 years
Annual Depreciation = (₹1,20,000 - ₹20,000) / 10 years
Annual Depreciation = ₹1,00,000 / 10 = ₹10,000 per year.
The company will record a depreciation expense of ₹10,000 for this machine each year for 10 years.
4. What are the key advantages of using the Straight Line Method in accounting?
The main advantages of the Straight Line Method are:
- Simplicity: It is the easiest method to understand and calculate, requiring no complex computations.
- Consistency: It results in a uniform depreciation charge each year, which makes comparing profitability across different accounting periods simpler.
- Full Depreciation: The asset's value is depreciated down to its salvage value, ensuring the entire depreciable amount is written off over its useful life.
5. How does the Straight Line Method (SLM) differ from the Written Down Value (WDV) Method?
The primary difference lies in the basis of calculation and the resulting annual expense. In the Straight Line Method, depreciation is calculated on the original cost of the asset, leading to a constant depreciation amount each year. In contrast, the Written Down Value Method calculates depreciation on the book value (cost less accumulated depreciation) of the asset, resulting in a depreciation amount that decreases each year.
6. Why is the Straight Line Method considered most appropriate for certain types of assets and not others?
The Straight Line Method is most suitable for assets that generate revenue or provide utility evenly throughout their useful life. For example, assets like buildings, furniture, and long-term leases are a good fit. This is because their pattern of use does not significantly diminish over time. However, it is less suitable for assets like machinery or vehicles, which are often more efficient and productive in their early years and whose repair costs increase as they age. For such assets, the Written Down Value method is often preferred as it allocates higher depreciation in the initial years.
7. In the SLM formula, why is it important to use an 'estimated' salvage value and 'estimated' useful life?
Using 'estimated' values is crucial because both salvage value and useful life are projections about the future, which cannot be known with certainty at the time of purchasing the asset. The salvage value is an educated guess of what the asset might be worth at the end of its service period. Similarly, the useful life is an estimation of how long the asset will remain productive for the business. These estimates are based on industry standards, manufacturer guidelines, and past experience, and they directly impact the annual depreciation amount.
