Double declining depreciation =

Rate of double declining depreciation = 36%
Depreciation in year 2018 = $50,000
36% = $18,000
Book value at year end = $50,000 - $18,000 = $32,000
Depreciation for 2019 = $32,000
36% = $11,520
Book value at end of 2019 = $32,000 - $11,520 = $20,480
After this straight line method is followed.

Depreciation for 2020 = $5,160
Depreciation for 2021 = $5,160
Depreciation for 2022 = $5,160
