Straight Line Method

The Straight-line depreciation is a very common, and the simplest, method of calculating depreciation expense. In straight-line depreciation, the expense amount is the same every year over the useful life of the asset.

 Formula for the Straight-Line Method:

Depreciation Expense = (Cost – Residual Value) / Useful life or Rate%


Company A buys a car for R100 000. The depreciation rate is 20% per annum on a straight line method
