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.
This method lets you deduct the same amount of depreciation each year over the useful life of the property. To figure your deduction, first determine the adjusted basis, salvage value, and estimated useful life of your property. Subtract the salvage value, if any, from the adjusted basis. The balance is the total depreciation you can take over the useful life of the property.
