Method Comparisons and Units of Production

Depreciation method terms comparing straight-line, balance, production-unit, and depletion-linked approaches.

Method Comparisons and Units of Production covers depreciation method terms comparing straight-line, balance, production-unit, and depletion-linked approaches.

Use these pages when asset-cost allocation changes earnings, tax timing, cash-flow interpretation, capital intensity, or valuation adjustments. It sits inside Depreciation Methods and Conventions, so readers can move up when the broader accounting context matters.

Use the table below to choose the narrower accounting branch before applying a term to a statement line, model input, audit trail, tax schedule, covenant test, or management report.

What This Branch Covers

AreaUse it for
Depreciation, Depletion, and Amortization (DD&A)Cost-allocation measure covering depreciation of assets, depletion of resources, and amortization of deferred costs.
Depreciation vs DepletionDepreciation vs depletion compares cost allocation for tangible fixed assets with natural-resource assets in accounting, tax, and valuation analysis.
Diminishing-Balance MethodThe diminishing-balance method, also known as the reducing-balance method, is a technique used to calculate depreciation, which gradually reduces the value of an asset over time.
Equal-Instalment DepreciationStraight-line depreciation method that allocates equal expense to each period of an asset’s useful life.
Linear DepreciationLinear depreciation refers to depreciation charges that result in a straight line when plotted on a graph, indicating a constant amount is written off each year.
Production-Unit MethodThe production-unit method, also known as the units of production method, is a technique used for calculating depreciation.
Reducing Balance DepreciationReducing balance depreciation is a method of depreciating fixed assets by writing down a constant percentage of their remaining value each year.

What to Check

  • Asset cost, useful life, residual value, placed-in-service date, method, convention, and accumulated depreciation or amortization.
  • Book policy, tax method, depreciation schedule, impairment history, disposal record, and recapture calculation.
  • Effect on EBIT, EBITDA, taxable income, book value, deferred tax, capex, and maintenance-versus-growth spending analysis.
  • Whether the figure is book depreciation, tax depreciation, depletion, amortization, or noncash add-back.
  • Comparability across methods, asset ages, reporting periods, and capital intensity.

Common Mistakes

  • Treating depreciation as current cash spending.
  • Ignoring differences between book and tax depreciation.
  • Comparing EBITDA without considering replacement capex and asset age.
  • Assuming accelerated depreciation changes economic useful life rather than tax or earnings timing.

Depreciation and amortization content is educational and does not provide accounting, tax, audit, legal, investment, or valuation advice.
