Introduction
Generally, when we talk about the cost of any particular asset, we tend to naturally think about the monetary aspects of the asset. However, the cost of assets for calculating depreciation includes several other key attributes as well, other than only money. As a result, there are numerous depreciation calculation methods used to analyse these costs. These costs, therefore, include several other components such as cost price, duties, handling expenses, among others.
Therefore, through the ways of this article, these methods shall be discussed with respect to the cost of assets and more specifically the accumulated depreciation formula, among others.
Depreciation Calculation Methods
With regards to calculating the decrease of the value of a company’s assets in a market, there are four primary methods that are used, namely: Straight Line Depreciation, Units of Production Depreciation, Sum of the Years’ Digits Depreciation and Declining Balance Depreciation. Each of these methods serves a distinct purpose whether with regards to calculating depreciation expense or something else.
Therefore, these methods exist to carry out a number of depreciation formula accounting practices among firms and businesses in terms of their operations. Therefore, the formulas that are used in order to calculate the depreciation of an asset’s value in a market vary differently with the kind of method that is being used to calculate.
As a result, the depreciation calculation formula is different for different methods. Three of the formulas are:
Straight-Line Depreciation Method= \[\frac{\text{Cost of Asset - Residual Value}}{\text{Useful Life of a Particular Asset}}\]
Diminishing Balance Method= \[\frac{\text{Cost of Asset * Rate of Depreciation}}{\text{100}}\]
Unit of Product Method = \[\frac{\text{Cost of Asset - Salvage Value}}{\text{Useful Life in the Form of Produced Units}}\]
As can be understood, there is no universal depreciable value formula which can be used to calculate the depreciation of an asset’s cost over time. And, similar to this, there are other important aspects to depreciation as well, such as accumulated depreciation, depreciable cost and others.
Accumulated Depreciation Formula
In order to calculate accumulated depreciation of a company’s assets, the salvage value or the estimated scrap is subtracted from the asset’s initial cost. Therefore, through the proper implementation of this formula, the accumulated depreciation of an asset’s value in a market is determined.
Therefore, the formula for the accumulated depreciation of an asset’s value is:
\[\frac{\text{Cost of Asset - Salvage Value}}{\text{ Life of Asset}}\] * Numbers of Years
Depreciable Cost
While discussing the assets of depreciation calculation, the facet of depreciable cost plays a big role. Defined as an asset’s cost which is susceptible to be depreciated with time it is, in effect, the same as the asset’s acquisition cost, without its salvage value.
Therefore, the Formula for the Depreciable Cost is: Original Cost- Salvage Value
Book Value Formula Depreciation
While discussing assets for depreciation calculation in a stable marketplace, it is imperative to discuss the book value of the asset. The book value is defined as the value of an item (asset) after the depreciation of the asset has been accounted for. Therefore, the significance of the book value of an asset lies with the asset’s allowance of depreciation over time. Similarly, the book value is a significant indicator of a business’s depreciation values and how much of them can be written off on the taxes of the business. Therefore, the book value of an asset is highly dependent on its ability to attract investors.

FAQs on Asset Costs for Depreciation Calculation
1. What exactly is included in the 'cost of an asset' for depreciation calculation?
The cost of an asset is not just its purchase price. For depreciation purposes, it includes all expenses required to get the asset ready for its intended use. This typically includes:
- The basic purchase price of the asset.
- Freight charges or shipping costs to bring it to the location.
- Installation costs and assembly fees.
- Any expenses for trial runs or testing before it is put into official use.
In short, it's the total amount spent to make the asset operational.
2. What are the main methods used to calculate depreciation as per the CBSE syllabus?
For Commerce students, the two primary methods for calculating depreciation are:
- Straight-Line Method (SLM): Where the same amount of depreciation is charged every year throughout the asset's life.
- Written-Down Value (WDV) Method: Where depreciation is charged at a fixed percentage on the asset's book value, which decreases each year.
3. How does the Straight-Line Method (SLM) for depreciation work?
The Straight-Line Method is the simplest way to calculate depreciation. It spreads the cost of an asset evenly over its useful life. The idea is that the asset contributes to revenue equally every year. The formula is:
Depreciation per year = (Total Cost of Asset - Estimated Scrap Value) / Estimated Useful Life of Asset
The amount of depreciation remains constant each year.
4. What is the key difference between the Straight-Line Method (SLM) and the Written-Down Value (WDV) method?
The main difference lies in how the depreciation amount is calculated over time. In the Straight-Line Method (SLM), the depreciation expense is the same every single year. In the Written-Down Value (WDV) Method, the depreciation expense is highest in the first year and decreases in subsequent years, because it's calculated on the reduced 'book value' of the asset.
5. Why is land not depreciated, but a building constructed on it is?
This is a fundamental concept in accounting. Land is generally considered to have an unlimited useful life. It does not wear out, decay, or become obsolete over time. In many cases, its value appreciates. A building, on the other hand, has a limited useful life. It deteriorates due to weather, wear and tear, and usage, which is why its cost is depreciated over the years it is expected to be useful.
6. What factors help decide the 'useful life' of an asset for depreciation calculations?
Estimating an asset's useful life is a crucial step. It's not a random guess but is based on several factors, including:
- The expected physical wear and tear from usage.
- Obsolescence, which is when an asset becomes outdated due to new technology.
- The manufacturer's estimated operational life.
- Legal or contractual limits, such as the expiry date of a lease.
7. How does charging depreciation affect a company's reported profit?
Depreciation is a non-cash operating expense. When a company calculates its profit, it subtracts expenses from revenue. By including depreciation as an expense, the company's net profit is reduced. While this means the profit shown on the income statement is lower, it also reduces the company's taxable income, which can lead to lower tax payments.
