A machine with a cost of $75,000 has an estimated residual value of $5,000 and an estimated life of 4 years or 18,000 hours. What is the amount of depreciation for the second full year, using the double-declining-balance method?

The answer is: $18, 750

Explanation:

The double-declining-balance (DDB) method entails computing depreciation of an asset at an accelerated rate. This method is employed when the asset loses value quickly and is expected to generate more revenue at the earlier stages of its useful life. The depreciation is higher at the beginning and lower close to the end of the asset's useful life. The depreciation is computed as follows:

Depreciation = 2 * straight line depreciation percentage * Book value at the beginning of the period

Machine cost: $75, 000

Residual Value: $5, 000

Estimated Life: 4 years/18, 000 hours

Straight line depreciation percentage : 100/4 = 25%

Depreciation Year 1 on DDB = 2 * 25% * $75, 000

= $37, 500

Depreciation Year 2 on DDB = 2 * 25% * ($75, 000 - $37, 500)

= $18, 750
