Cost accounting

Cost accounting is a central element of managerial accounting.
Grenzplankostenrechnung (GPK)
Grenzplankostenrechnung is a German costing methodology, developed in the late 1940s and 1950s, designed to provide a consistent and accurate application of how managerial costs are calculated and assigned to a product or service. The term Grenzplankostenrechnung, often referred to as GPK, has best been translated as either Marginal Planned Cost Accounting or Flexible Analytic Cost Planning and Accounting.

The origins of GPK are credited to Hans Georg Plaut, an automotive engineer and Wolfgang Kilger, an academic, working towards the mutual goal of identifying and delivering a sustained methodology designed to correct and enhance cost accounting information. GPK is published in cost accounting textbooks, notably Flexible Plankostenrechnung und Deckungsbeitragsrechnung and taught at German-speaking universities today.
