## Introduction

Accumulated depreciation is a crucial concept in accounting and finance, reflecting the total depreciation expense allocated to a fixed asset since its inception. This guide will not only explain the essence of accumulated depreciation but also provide insights into its calculation using various methods.

## What is Accumulated Depreciation?

Fixed assets, such as vehicles, machinery, or buildings, have a limited useful life. Accumulated depreciation represents the total expense attributed to a fixed asset over its economic life. This ensures that the cost of the asset is matched with the revenue it generates over time.

## Methods of Calculating Accumulated Depreciation

Accumulated depreciation can be calculated using different methods, including:

1. Straight-Line Method:
• Formula: ((Cost of the Asset – Salvage Value) / Life of the Asset) × Number of Years
• Example: After 3 years, accumulated depreciation for a $25,000 toy machine with a 15-year life and$3,000 salvage value is $4,400. 2. Declining Balance Method: • Formula: (Current Book Value × Depreciation Rate) + Sum of Previous Years’ Depreciation • Example: After 2 years, accumulated depreciation for the same toy machine is$4,750.
3. Sum of the Year’s Digits Method:
• Formula: (Remaining Life Span/SYS × (Cost of the Asset – Salvage Value)) + Sum of Previous Years’ Depreciation
• Example: After 2 years, accumulated depreciation using this method is $5,316.67. 4. Units of Production Method: • Formula: (Asset Cost – Salvage Value) / Estimated Units Over Lifespan × Actual Units Produced • Example: After 2 years, accumulated depreciation, considering units produced, is$24,805.33.

Applicability of Accumulated Depreciation:

Applies to vehicles, machinery, tools, and buildings.

Not applicable to land, as land does not depreciate over time.

Calculating Accumulated Depreciation for a Building after 5 Years:

Example calculation using the straight-line method provided.

Finding the Current Book Value:

Book value equals the original cost minus accumulated depreciation.

Example Calculation:

If accumulated depreciation is $14,000 for a$20,000 asset, the current book value is \$6,000.

## Conclusion
