Cost Analysis Course

Lesson 1 • Cost Classification Systems

Covers the major ways costs are classified: by behaviour, traceability, and function. Correct classification is the prerequisite for every analytical technique introduced later.

Lesson 2 • What Cost Analysis Means

Defines cost analysis and its role in organisational decision-making. Establishes why systematic cost examination drives profitability and operational efficiency.

Lesson 3 • The Cost Analysis Process

Outlines the end-to-end workflow from data collection to insight delivery. Students gain a repeatable process model they will apply throughout the course.

Lesson 1 • Separating Mixed Costs

Teaches the high-low method and scatter plot analysis to isolate fixed and variable components of mixed costs. These techniques form the basis for more advanced regression analysis.

Lesson 2 • Regression-Based Cost Estimation

Applies simple and multiple regression to estimate cost functions with statistical rigour. Students interpret R-squared, coefficients, and p-values to validate their models.

Lesson 3 • Learning Curves in Cost Estimation

Introduces the learning curve effect where unit costs decline as cumulative output rises. Accurate learning curve modelling improves pricing and production cost projections.

Lesson 4 • The Relevant Range Concept

Defines the activity range within which cost behaviour assumptions hold valid. Misapplying cost functions outside the relevant range leads to significant forecasting errors.

Lesson 1 • Activity-Based Costing Fundamentals

Introduces ABC as a more accurate alternative to traditional overhead allocation by linking costs to activities. Students identify activities, assign costs to activity pools, and compute activity rates.

Lesson 2 • Principles of Cost Allocation

Explains why indirect costs must be allocated and the criteria for selecting allocation bases. Sound allocation principles prevent cross-subsidisation between products or departments.

Lesson 3 • Service Department Cost Allocation

Addresses allocation of support department costs to production departments using direct, step-down, and reciprocal methods. Method choice affects reported product costs significantly.

Lesson 4 • ABC Implementation and Analysis

Guides students through a full ABC implementation cycle and comparison with traditional costing results. Differences in product costs reveal cross-subsidisation and inform pricing decisions.

Lesson 1 • Process Costing Fundamentals

Explains cost accumulation for homogeneous mass-production processes using equivalent units. Students compute cost per equivalent unit and assign costs to completed and in-process units.

Lesson 2 • Hybrid and Operation Costing

Introduces operation costing for products sharing some processes but differing in others. Students design hybrid systems that blend job-order and process costing logic.

Lesson 3 • Spoilage, Waste, and Scrap

Distinguishes normal from abnormal spoilage and explains their different accounting treatments. Proper spoilage accounting prevents distortion of unit costs and period results.

Lesson 4 • Joint and By-Product Costing

Addresses cost allocation for processes that simultaneously produce multiple products from a common input. Students apply physical units, sales value, and net realisable value methods.

Lesson 1 • CVP Assumptions and Framework

Establishes the assumptions underlying CVP analysis and introduces contribution margin logic. Understanding these boundaries prevents misapplication of CVP results.

Lesson 2 • Sensitivity and Scenario Analysis

Applies what-if analysis to test how changes in price, cost, and volume affect break-even and profit. Sensitivity analysis quantifies risk and supports contingency planning.

Lesson 3 • Break-Even and Target Profit Analysis

Calculates break-even points in units and revenue and extends the model to target profit scenarios. These calculations anchor pricing, volume, and cost-reduction decisions.

Lesson 1 • Standard Cost System Design

Explains how standard costs are set for materials, labour, and overhead using engineering and historical data. Well-designed standards motivate efficiency without creating unachievable targets.

Lesson 2 • Overhead Variance Analysis

Decomposes overhead variances into spending, efficiency, and volume components for both variable and fixed overhead. Students reconcile applied overhead with actual overhead incurred.

Lesson 3 • Flexible Budgets and Performance

Contrasts static and flexible budgets and explains why flexible budgets enable fair performance evaluation. Students prepare flexible budgets at multiple activity levels.

Lesson 4 • Direct Cost Variance Analysis

Computes and interprets price and efficiency variances for direct materials and direct labour. Variance decomposition pinpoints whether cost overruns stem from price or usage issues.

Lesson 1 • Make-or-Buy and Outsourcing

Evaluates whether to produce internally or purchase from an external supplier using differential cost analysis. Students incorporate qualitative factors such as quality control and supplier risk.

Lesson 2 • Product Line and Segment Decisions

Determines whether to add, retain, or drop a product line or business segment using contribution margin and avoidable cost analysis. Common cost allocation distortions are identified and corrected.

Lesson 3 • Relevant Cost Concepts

Defines relevant costs as future, differential costs that differ between alternatives. Distinguishing relevant from irrelevant costs prevents sunk cost fallacies and misleading analyses.

Lesson 4 • Special Order Decisions

Analyses whether to accept a one-time order priced below the normal selling price. Students assess incremental costs, idle capacity, and strategic implications.

Lesson 1 • Value Chain and Cost Positioning

Maps the value chain to identify cost drivers and differentiation opportunities at each stage. Strategic cost positioning determines whether a firm competes on cost leadership or differentiation.

Lesson 2 • Kaizen Costing and Continuous Improvement

Applies incremental cost reduction targets to existing products during the manufacturing phase. Kaizen costing complements target costing by sustaining cost discipline after product launch.

Lesson 3 • Balanced Scorecard and Cost Metrics

Integrates cost metrics into a balanced scorecard framework linking financial, customer, process, and learning perspectives. Students design cost-related KPIs that align operational behaviour with strategy.

Lesson 4 • Life-Cycle Costing

Tracks all costs incurred across a product's full life cycle from design through disposal. Life-cycle perspective reveals that upstream decisions lock in the majority of total product costs.
