Key Concepts

Depreciation

The permanent, continuous, and gradual decrease in the book value of a fixed asset due to wear and tear, efflux of time, or obsolescence.

Straight Line Method (SLM)

A method where depreciation is calculated on the original cost of the asset and remains constant every year throughout its useful life.

Written Down Value (WDV) Method

A method where depreciation is calculated every year on the reduced balance (book value) of the asset, resulting in decreasing depreciation amounts over time.

Provision

A liability or loss of uncertain amount created for a known contingency, such as Provision for Depreciation or Provision for Bad Debts.

Reserve

Amounts set aside out of profits to strengthen the financial position of the business, which can be general or specific.

Important Formulas

Depreciation under SLM = (Original Cost of Asset - Estimated Scrap Value) / Estimated Useful Life of Asset
Rate of Depreciation (SLM) = (Annual Depreciation / Original Cost) * 100
Book Value = Original Cost of Asset - Total Depreciation Charged up to Date

Frequently Asked Questions

What is the main difference between SLM and WDV methods of depreciation?

In SLM, depreciation is calculated on the original cost and remains equal every year. In WDV, depreciation is calculated on the diminished book value, so the depreciation amount decreases every year.

Are provisions charged against profits or appropriated from profits?

Provisions are a charge against profits, meaning they must be provided even if the business incurs a net loss.

Why is depreciation considered a non-cash expense?

Because it represents the reduction in the value of an asset without any actual outflow of cash from the business.
