The concept of straight line basis in capital budgeting refers to a method used to allocate the cost of an asset evenly over its useful life. It is a widely employed technique for calculating
depreciation expense, which is an essential component of capital budgeting. Capital budgeting involves evaluating and selecting investment projects that
yield long-term benefits for a company.
When a company acquires a tangible asset, such as machinery, equipment, or buildings, it incurs a cost that is spread over the asset's useful life. The straight line basis method assumes that the asset's value decreases at a constant rate over time. Under this approach, the cost of the asset is divided equally by the number of years it is expected to be useful.
To calculate depreciation using the straight line basis, the following formula is applied:
Depreciation Expense = (Cost of Asset - Salvage Value) / Useful Life
The cost of the asset represents its original purchase price, including any additional costs incurred to make it operational, such as installation or transportation fees. The salvage value refers to the estimated residual value of the asset at the end of its useful life. The useful life is the estimated period during which the asset will generate economic benefits for the company.
By using the straight line basis, companies can allocate the cost of an asset in a systematic and consistent manner over its useful life. This approach provides several advantages in capital budgeting:
1. Simplicity: The straight line basis is straightforward and easy to understand. It does not require complex calculations or assumptions about varying depreciation rates.
2. Even allocation: This method ensures that the cost of the asset is distributed evenly over its useful life. It allows for a more accurate representation of the asset's contribution to revenue generation throughout its lifespan.
3. Predictability: The straight line basis provides a predictable pattern of depreciation expenses, which aids in financial planning and budgeting. Companies can anticipate and incorporate these expenses into their
cash flow projections.
4. Comparability: Since the straight line basis is a commonly used method, it facilitates the comparison of financial statements across different companies and industries. It enhances the
transparency and consistency of financial reporting.
However, it is important to note that the straight line basis has limitations. It assumes a linear decline in the asset's value, which may not reflect its actual pattern of depreciation. Some assets may experience higher depreciation in the early years and lower depreciation in later years. Additionally, the straight line basis does not consider the time value of
money, as it assumes an equal allocation of costs over time.
In conclusion, the concept of straight line basis in capital budgeting involves allocating the cost of an asset evenly over its useful life. This method simplifies depreciation calculations, ensures even allocation of costs, provides predictability, and enhances comparability. While it has its limitations, the straight line basis remains a widely used approach in capital budgeting for its simplicity and consistency.
