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.
Multiply the current depreciable basis by the depreciation rate to find the year's depreciation. 1  In the first year of use, the depreciation will be $400 ($1,000 x 40 percent). 2  For the second year, the depreciable value is now $600 ($1,000 - 400) and the annual depreciation will be $240 ($600 x 40 percent).alculate the depreciation rate. 1  Sum the numbers of the years in the asset's depreciable life. 2  In the first year, divide the sum by the last number (5 / 15); in the second year the sum is divided by the second-to-last number (4 / 15) and so forth down the column to find the percentage of depreciation rate for each year.
