In early July 2019, Masterton Ltd is considering the acquisition of some machinery for $1 320 000 (GST inclusive) to be used in the manufacture of a new product. The machinery has a useful life of 10 years, during which management plans to produce 500 000 units of the new product. The residual value of the machinery is $100 000.

The following projections were made in order to select a depreciation method to be used for the machinery.

year ended 30 June units of output repairs and profit

maintenance before depriciation

2020 50000 70000 350000

2021 45000 60000 340000

2022 55000 90000 355000

2023 58000 95000 360000

2024 60000 100000 380000

In calculating the profit before depreciation, all expenses have been deducted, including the repairs and maintenance expense.
