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.
How to Account for Depreciation and Amortization. Assume, for example, that a carpenter uses a $32,000 truck to perform residential carpentry work, and that the truck has a useful life of eight years. The annual depreciation expense on a straight-line basis is the $32,000 cost basis divided by eight years, or $4,000 per year. On the other hand, assume that a corporation pays $300,000 for a patent that allows the firm exclusive rights over the intellectual property for 30 years, and the firm's accounting department posts $10,000 of amortization expense each year for 30 years. Both the truck and the patent are used to generate revenue and profit over a particular number of years.
