Double Declining Balance (DDB)

Overview

The Double Declining Balance (DDB) method is an accelerated depreciation technique that depreciates assets at twice the rate of the standard straight-line method. This means a higher percentage of the asset’s value is depreciated early in its useful life, which can provide greater tax benefits sooner. It contrasts with the straight-line method, where the asset’s value is depreciated evenly over its useful life.

Examples

Example Scenario

Consider a piece of equipment purchased for $10,000 with a useful life of 5 years. The straight-line depreciation rate would be 20% per year (100% / 5 years). For DDB, the rate applied is 40% (20% * 2).

Depreciation Schedule:

Year 1: Depreciation = ($10,000 * 40%) = $4,000
- Remaining Value: $10,000 - $4,000 = $6,000
Year 2: Depreciation = ($6,000 * 40%) = $2,400
- Remaining Value: $6,000 - $2,400 = $3,600
Year 3: Depreciation = ($3,600 * 40%) = $1,440
- Remaining Value: $3,600 - $1,440 = $2,160
Year 4: Depreciation = ($2,160 * 40%) = $864
- Remaining Value: $2,160 - $864 = $1,296
Year 5: Depreciation = ($1,296 * 40%) = $518.40
- Remaining Value: $1,296 - $518.40 = $777.60

Frequently Asked Questions

What are the advantages of using the Double Declining Balance method?

The main advantage is the upfront tax savings, as it allows businesses to write off more of the asset’s cost earlier in its life.

Is the Double Declining Balance method suitable for all types of assets?

No, it is particularly suitable for assets that lose their value quickly or have higher productivity in the early years of use.

Can the DDB method be applied to real estate?

Generally, buildings and real estate are depreciated using the straight-line method. The DDB method is not typically used for these types of assets.

How does the DDB method affect financial statements?

Initially, it will show higher expense charges, reducing net income in the early years. However, this levels out as the asset gets older.

Depreciation: The systematic allocation of the cost of a tangible asset over its useful life.
