Accounting for Depreciation

Methods used to depreciate noncurrent assets

Depreciation is an accounting method used to allocate the cost of noncurrent assets over their useful life. It is important for businesses to understand and apply the appropriate methods of depreciation in order to accurately reflect the decrease in value of their assets over time. In this section, we will explore the various methods used to depreciate noncurrent assets.

Straight-line depreciation

The straight-line depreciation method is the most commonly used and simplest method of depreciation. It assumes that the asset decreases in value evenly over its useful life. The formula for calculating straight-line depreciation is:

Depreciation expense = (Cost of asset – Salvage value) / Useful life

Where:

 Cost of asset is the original cost of the asset

 Salvage value is the estimated value of the asset at the end of its useful life

 Useful life is the estimated number of years the asset will be used

For example, if a company purchases a machine for £10,000 with a salvage value of £2,000 and an estimated useful life of 5 years, the annual depreciation expense would be calculated as follows:

Depreciation expense = (£10,000 – £2,000) / 5 = £1,600

Therefore, the company would record a depreciation expense of £1,600 each year for the next 5 years.

Declining balance depreciation

The declining balance depreciation method is an accelerated depreciation method that assumes the asset loses more value in the early years of its useful life. This method allows businesses to deduct higher depreciation expenses in the earlier years, which can be beneficial for tax purposes. The formula for calculating declining balance depreciation is:

Depreciation expense = (Book value at the beginning of the year x Depreciation rate)

Where:

 Book value at the beginning of the year is the original cost of the asset minus accumulated depreciation

 Depreciation rate is a percentage determined by the useful life and the desired rate of depreciation

For example, if a company uses a declining balance depreciation method with a depreciation rate of 20% on a machine with an original cost of £10,000 and a useful life of 5 years, the depreciation expense for the first year would be calculated as follows:

Depreciation expense = (£10,000 – £0) x 20% = £2,000

Assuming no salvage value, the book value at the beginning of the second year would be £8,000 (£10,000 – £2,000), and the depreciation expense for the second year would be calculated as follows:

Depreciation expense = (£8,000 – £0) x 20% = £1,600

This process would continue for the remaining years of the asset’s useful life.

Units of production depreciation

The units of production depreciation method is used when an asset’s useful life is determined by the number of units it can produce or the number of hours it can be used. This method is particularly useful for assets such as vehicles or machinery that are used to produce goods or provide services. The formula for calculating units of production depreciation is:

Depreciation expense per unit = (Cost of asset – Salvage value) / Total estimated units of production

Depreciation expense = Depreciation expense per unit x Units produced or hours used

For example, if a company purchases a machine for £10,000 with a salvage value of £2,000 and estimates that the machine can produce 10,000 units, the depreciation expense per unit would be calculated as follows:

Depreciation expense per unit = (£10,000 – £2,000) / 10,000 = £0.80

If the company produces 1,000 units in a given year, the depreciation expense for that year would be:

Depreciation expense = £0.80 x 1,000 = £800

This method allows for a more accurate reflection of an asset’s decrease in value based on its actual usage.

Conclusion

Understanding the methods used to depreciate noncurrent assets is crucial for businesses to accurately account for the decrease in value of their assets over time. The straight-line, declining balance, and units of production methods each have their own advantages and disadvantages, and businesses should choose the method that best aligns with their specific circumstances. By applying the appropriate depreciation method, businesses can ensure that their financial statements

accurately reflect the true value of their assets and make informed decisions regarding future investments.
