How to Calculate Monthly Accumulated Depreciation. Depreciation can be calculated on a monthly basis by two different methods. Over time, the assets a company owns lose value, which is known as depreciation. As the value of these assets declines over time, the depreciated amount is recorded as an expense on the balance sheet.
Step 3: Multiply the asset's book value by the double depreciation % to get the current year depreciation. In the first year, the book value is the same as its cost. asset book value * double depreciation % = current year depreciation. Step 4: Subtract the current year depreciation from the book value of the asset. The result will be used as the new book value used to calculate depreciation for the next year. book value of asset - current year depreciation. Example: ABC Company bought a tractor with a 3 year useful life and a $2,000 residual value for $30,000. Step 1: 100 / 3 = 33.33% annual depreciation.
