Depreciation

When a business buys a piece of equipment for $50,000 that will last 10 years, it would be misleading to record the entire $50,000 as an expense in year one. The equipment provides value over a decade, so the expense should be recognized gradually. That is what depreciation accomplishes. It matches the cost of the asset to the revenue it helps generate, following the matching principle in accounting. Several methods exist for calculating depreciation. Straight-line depreciation divides the cost evenly over the useful life: $50,000 over 10 years equals $5,000 per year. Declining balance methods front-load the expense, recognizing more depreciation in early years when the asset is newer and theoretically more productive. Units-of-production ties depreciation to actual usage rather than time. The choice of method affects reported profits and tax obligations. Many jurisdictions allow accelerated depreciation for tax purposes, letting businesses deduct more in early years and defer tax payments. This creates a difference between "book depreciation" (for financial reporting) and "tax depreciation" (for tax returns), which the accounting system needs to track separately. Asset management in an ERP ties depreciation to the broader fixed asset register. The system tracks each asset from acquisition through its useful life to disposal, calculating depreciation automatically each period and posting the journal entries to the general ledger.
