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.
The straight-line method of calculating depreciation would be to divide the initial cost by the asset's useful life. So if a company buys a machine for $100,000, and its useful life is determined to be 10 years, it depreciates in value by $10,000 every year.
