## 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:

**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.

**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.

**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.

**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.
