Activity-Based Costing for Management Decisions Training Course

Course overview

Traditional cost allocation based on direct labour hours, machine hours, or broad departmental rates can distort product, customer, channel, and service-line profitability. Managers then price contracts using misleading margins, retain loss-making customers, or make outsourcing decisions on incomplete cost information. This course equips finance professionals to replace broad averaging with an activity-based costing (ABC) model that traces overhead through the activities that actually consume resources.

Participants learn to define cost objects, map processes and activity pools, select defensible cost drivers, calculate activity rates, and assign costs to products, services, customers, and internal projects. The course covers both conventional ABC and time-driven activity-based costing (TDABC), including capacity cost rates, practical capacity, unused-capacity reporting, and scenario analysis. Participants also use ABC information for pricing, product mix, customer profitability, budgeting, process improvement, make-or-buy analysis, and performance reporting.

Instruction combines worked calculations, Excel model-building, facilitated review of cost-driver choices, and case material drawn from manufacturing, shared services, and customer-facing operations. Participants build an auditable ABC model with activity dictionaries, driver definitions, cost assignments, profitability reports, and management decision recommendations. They leave with a reusable model structure and an implementation plan for applying ABC in their own organisation.

The course is designed for experienced finance and operational professionals who need to produce decision-useful cost information rather than simply reconcile overhead to the general ledger. It is particularly valuable where indirect costs are material, product or customer complexity is increasing, or leaders need clearer evidence behind margin and resource-allocation decisions.

Course objectives

By the end of this course, participants will be able to:

• Map end-to-end processes into activities, resource pools, and defined cost objects for an ABC model
• Select and test cause-and-effect cost drivers using operational data and driver-quality criteria
• Calculate resource, activity, and cost-object rates in an auditable Microsoft Excel ABC model
• Assign indirect costs to products, customers, services, and projects using activity consumption measures
• Build a time-driven activity-based costing model using capacity cost rates and time equations
• Produce product, customer, and channel profitability reports that reconcile to source cost data
• Evaluate pricing, product mix, make-or-buy, and process-improvement decisions using ABC outputs
• Prepare an ABC implementation roadmap including data requirements, governance roles, and model controls

Benefits of attending

Target competencies

Who should attend

• Management Accountants — who need more reliable cost allocation and profitability analysis for management reporting
• Financial Controllers — who must govern costing models and defend margin information used in business decisions
• FP&A Managers — who translate cost and profitability data into budgets, forecasts, and investment recommendations
• Cost Accountants — who maintain product or service costing systems in overhead-intensive operations
• Operations Managers — who need visibility of activity consumption, process cost, and unused capacity
• Commercial and Pricing Managers — who require defensible customer, contract, and product margin evidence

Requirements and prerequisites

Participants should already understand basic management accounting concepts, including direct versus indirect costs, cost centres, overhead allocation, contribution margin, and budget-versus-actual reporting. Confidence using Microsoft Excel is required: participants should be able to use formulas, tables, filters, and PivotTables, although advanced macros or programming are not required. Familiarity with their organisation’s chart of accounts, operational volumes, and ERP cost reports will help participants apply the material quickly. No prior experience of activity-based costing, Power BI, SAP S/4HANA, or time-driven ABC is required.

Training methodology

The course uses instructor-led costing demonstrations followed by structured Excel workshops in which participants construct and test an ABC model. Short cases require teams to map activities, challenge weak cost drivers, calculate activity rates, and interpret profitability results for management decisions. Participants work with sample general-ledger extracts, operational-volume data, and capacity measures, then visualise selected outputs in Power BI. Daily review sessions connect calculations to practical governance issues, and the final day closes with an individual application plan for a live costing challenge.

Course outline

Day 1: ABC foundations and costing-model design

• Limits of traditional absorption costing and volume-based allocation
• ABC terminology: resources, activities, cost pools, drivers, and cost objects
• Identifying material indirect-cost distortions in products and services
• Defining the purpose and scope of an ABC model
• Process mapping techniques for finance and operational teams
• Designing an activity dictionary and activity hierarchy
• Establishing model boundaries, materiality thresholds, and reconciliation rules

Workshop: Participants map a selected operating process into resource pools, activities, cost objects, and an initial activity dictionary for a case organisation.

Day 2: Cost pools, drivers, and activity-rate calculation

• Extracting and cleansing general-ledger cost data for ABC
• Resource-driver analysis and first-stage cost assignment
• Selecting transaction, duration, intensity, and complexity cost drivers
• Testing driver causality, measurability, behavioural impact, and data availability
• Calculating activity cost pools and activity rates in Microsoft Excel
• Managing shared services, support functions, and reciprocal-service allocations
• Reconciling ABC assigned costs to the general ledger

Workshop: Participants build an Excel cost-pool and driver-rate schedule, then reconcile assigned activity costs to the case company’s ledger total.

Day 3: Profitability analysis and management decisions

• Second-stage assignment from activity pools to cost objects
• Product-line profitability and unit-cost analysis
• Customer, channel, and contract profitability modelling
• Order complexity, service levels, and cost-to-serve analysis
• Using ABC outputs in pricing and quotation decisions
• Product mix and discontinuation decisions using relevant costs
• Make-or-buy and outsourcing analysis with avoidable-cost logic

Workshop: Teams produce a customer and product profitability report, identify cross-subsidies, and present two pricing or portfolio recommendations.

Day 4: Time-driven ABC, capacity, and reporting

• Principles and use cases of time-driven activity-based costing
• Calculating practical capacity and capacity cost rates
• Building time equations for variable transaction complexity
• Measuring unused capacity and capacity-sustaining costs
• Comparing conventional ABC and TDABC model design choices
• Sensitivity analysis for driver volumes, rates, and demand scenarios
• Visualising ABC profitability and capacity results in Power BI

Workshop: Participants create a TDABC time equation and capacity report for a service operation, including unused-capacity cost and scenario results.

Day 5: Implementation, governance, and application planning

• Assessing data sources from ERP, operational systems, and time studies
• Configuring ABC data structures in SAP S/4HANA Controlling
• Model governance, ownership, documentation, and version control
• Driver-data validation and periodic model refresh procedures
• Communicating ABC findings to operational and commercial stakeholders
• Linking ABC to budgeting, rolling forecasts, and performance management
• Developing a phased ABC implementation business case and roadmap

Workshop: Participants complete and peer-review an ABC implementation plan containing scope, data requirements, stakeholders, controls, milestones, and decision priorities.
