Reducing Balance Depreciation: Method of Depreciating Fixed Assets

Reducing balance depreciation is a method used to calculate the depreciation expense for fixed assets by applying a constant percentage to the asset’s book value each year. This method contrasts with the straight-line depreciation method, which allocates an equal depreciation expense each year.

1. Double Declining Balance Method

This method applies twice the straight-line depreciation rate to the declining book value of the asset.

2. 150% Declining Balance Method

This variant uses 1.5 times the straight-line depreciation rate.

Formula for Reducing Balance Depreciation

The general formula for calculating depreciation using the reducing balance method is:

Where the depreciation rate is calculated as:

Example Calculation

Suppose a machine costs $10,000, has a useful life of 5 years, and a residual value of $2,000. The depreciation rate would be:

Then the annual depreciation would be applied as follows: Year 1: $10,000 × 0.369 = $3,690 Year 2: $(10,000 - 3,690) × 0.369 ≈ $2,315$

Importance

The reducing balance method is significant for assets that lose more value in the earlier years of their useful life, providing a more realistic view of an asset’s declining utility. Commonly applied to machinery, vehicles, and equipment, it aligns the expense with the economic benefit derived from the asset.
