Forecasting noncash expenses can be more difficult than cash expenses, but it is necessary for a financial forecast to be complete. Noncash expenses include depreciation, amortization, and other costs that cannot be converted to cash. These types of expenses usually increase over time as the value of assets depreciates or becomes obsolete. The higher the rate of depreciation, the higher the expense will be relative to the asset's value. Compare depreciation methods and determine which one(s) work best for your business.
