Costing methods around the world
Almost every industrial country has produced its own answer to one question: what does it really cost us to make and serve what we sell? This hub maps the major methods side by side, where each came from, how it works, and which business it suits.
There is no single best costing method, only the method that fits the decision. Standard costing (US/UK) values inventory and flags variances but can reward overproduction. ABC and its faster successor TDABC trace overhead to activities and customers, and are strongest for cost-to-serve and customer profitability. GPK, the German standard, separates fixed from proportional cost across hundreds of cost centres for marginal decisions. UEP, widely used in Brazil, unifies a multi-product factory into one effort unit. Throughput accounting ignores overhead allocation and manages by the bottleneck. Target costing, born at Toyota, works backwards from market price to an allowable cost at the design stage. Most modern profitability work uses TDABC because it scales, surfaces unused capacity and traces cost to the customer.
A method for every industrial tradition
France and Brazil, Germany, Japan, the United States and Britain, Israel. Each line of thought solved the costing problem for its own industry and its own decisions.
Seven answers to the same question
Standard costing
USA / UKPredetermined costs and variance analysis. The backbone of inventory valuation under IFRS and US GAAP.
Read the profileActivity-based costing
USATraces overhead to activities, then to products and customers, through cost drivers. Powerful but heavy to maintain.
Read the profileTime-driven ABC
USATwo parameters per resource group: a capacity cost rate and time equations. Scales and surfaces unused capacity.
Read the profileGPK
GermanyMarginal planned cost across many cost centres, with a strict split of fixed and proportional cost. Its cousin is RCA.

France / BrazilTurns a multi-product factory into a single-product factory by measuring everything in one effort unit.

IsraelThree measures, no overhead allocation, and decisions made by the constraint. From Goldratt’s Theory of Constraints.

JapanWorks backwards from the market price to the cost a product is allowed to incur, then engineers the design to meet it.

Match the method to the decision
- Value inventoryYou will use standard or absorption costing whatever else you do, because IFRS (IAS 2) and US GAAP require it.
- Unprofitable customersYou want cost-to-serve work, and that means TDABC (or ABC if small and stable). These trace cost all the way to the customer.
- Complex ERP plantA strong controlling culture with integrated ERP gets the cleanest marginal cost from GPK or RCA, cost centre by cost centre.
- Many shared productsFor one honest measure of output and productivity across shared operations, the UEP method earns its place.
- A single bottleneckWhen output is gated by one constraint and you make frequent mix and pricing calls, throughput accounting stops the wrong answer.
- Cost set at designIf cost is decided in the design studio before the factory runs, target costing is the only method that acts where cost is actually set.
Frequently asked questions
What is the most widely used costing method?
For external financial reporting, standard or absorption costing is effectively universal, because IFRS and US GAAP require inventory to carry a systematic share of production overhead. For management decisions the picture is regional: activity-based and time-driven activity-based costing dominate the Anglo-American and consulting world, Grenzplankostenrechnung is the standard in German-speaking countries, and the UEP method is widely taught and applied in Brazil.
Which costing method is best for customer profitability?
Time-driven activity-based costing (TDABC). It traces the cost of serving each customer through time equations and a capacity cost rate, scales to thousands of transactions, and shows unused capacity explicitly. Classic ABC does the same job but is slower and costlier to maintain, which is why TDABC replaced it for most large models.
Why does Germany use a different costing method?
German cost accounting grew out of a strong engineering and controlling tradition that prizes the strict separation of fixed and proportional cost and causal assignment across many cost centres. Grenzplankostenrechnung, developed by Hans-Georg Plaut and Wolfgang Kilger from the late 1940s, became the standard because it gives managers a clean marginal cost for pricing and mix decisions, and it fits the integrated ERP systems German industry runs.
Is UEP only used in Brazil?
The underlying idea is French. The production-effort unit comes from the GP method of the French engineer Georges Perrin. It was carried to Brazil by Franz Allora and developed there into the UEP method, which is now far more widely used and taught in Brazil than anywhere else, especially in multi-product manufacturing.
Can you combine costing methods?
Yes, and most mature finance functions do. A company will value inventory with standard or absorption costing for the statutory accounts, run TDABC or GPK for management decisions, use target costing during product development, and reach for throughput thinking when a bottleneck dominates. Resource consumption accounting (RCA) is itself a deliberate blend of German GPK and activity-based drivers.
