What is Depreciation?

The systematic allocation of the cost of a tangible asset over its useful life, representing the decline in value due to wear, use, or obsolescence.

How It Works

Depreciation is a non-cash expense that spreads the cost of an asset over the years it generates revenue. Common methods include Straight-Line (equal amounts each year), Written Down Value/Declining Balance (higher in early years), and Units of Production (based on usage). Depreciation reduces taxable income and is governed by accounting standards (Ind AS 16, IAS 16) and tax laws (Income Tax Act schedules).

Formula

Straight-Line Depreciation = (Cost − Salvage Value) ÷ Useful Life

Real-World Example

A company buys machinery for ₹10,00,000 with a 10-year useful life and ₹1,00,000 salvage value. Annual depreciation = (₹10,00,000 − ₹1,00,000) ÷ 10 = ₹90,000 per year.

Frequently Asked Questions

Is depreciation a real expense?

Depreciation is a real accounting expense but not a cash expense — no money leaves the business when depreciation is recorded. It reflects the declining value of assets over time.

What is the difference between depreciation and amortization?

Depreciation applies to tangible assets (machinery, vehicles, buildings). Amortization applies to intangible assets (patents, trademarks, software licenses). The concept is the same — spreading cost over useful life.
