Cost Accounting: Fundamentals to Advanced with Excel Cases.

Identify fixed costs and variable costs, including mixed costs, with bakery examples like rent, insurance, and fixed salaries, and explain how costs affect budgeting, pricing, and profits through financial leverage.

Identify and analyze mixed costs, showing how fixed and variable components combine in electricity, maintenance, restaurant, and manufacturing examples to improve budgeting, pricing, and decision making.

Understand production costs: direct materials, direct labor, and manufacturing overhead capitalized as inventory and later becoming cost of goods sold, versus period costs including selling and administrative expenses expensed immediately.

Learn the difference between cost of goods sold and cost of goods manufactured, how each is calculated, and how they affect the income statement, balance sheet, and production planning.

See an Excel-based example that calculates cost of goods sold and cost of goods manufactured using beginning and ending inventories, direct materials, direct labor, and manufacturing overhead.

Apply job order costing to track the cost of each unique job—materials, labor, and overhead—to ensure profitability and accurate pricing.

Identify the three main components of job order costing: direct materials, direct labor, and manufacturing overhead; learn how overhead is allocated using an allocation base and a predetermined rate.

Build a practical Excel job order costing model for construction, detailing WBS-based tasks, direct material, direct labor, overhead, and budget-to-actual analysis.

Understand process costing in mass production by tracking department costs across batches through mixing, processing, and packaging to determine the average cost per unit.

Explore step-by-step process costing in real business contexts, covering physical flow analysis, equivalent units, total costs, unit cost, cost assignment to completed and in-progress units, and cost reconciliation.

Compute equivalent units in process costing by translating partially completed work into standardized measures, allocate costs with materials at 100% and conversion at 60% for ending work in progress.

Gather total cost data from beginning work in progress and current period costs, including direct and conversion costs; compute cost per equivalent unit and allocate to completed and in-progress units.

Explore a practical six-step process costing case in a juice mixing department, calculating equivalent units, cost per equivalent unit, and cost reconciliation using an Excel model.

Learn how to allocate overhead costs—indirect expenses like rent and utilities—across products using bases such as labor hours, machine hours, square footage, and direct materials, for true costs and pricing.

use direct labor hours to allocate overhead, compute total overhead and total labor hours, set an hourly rate, and allocate costs to products A and B for pricing.

Allocate overhead using the machine hours method by dividing 100,000 by 20,000 hours to set a 5 per hour rate, then apply 10 hours for product B to total 115.

use the square footage method to allocate 10,000 monthly net rent among marketing (25%), production (50%), and administration (25%), with allocations of 2,500, 5,000, and 2,500.

Discover activity-based costing by linking costs to activities and drivers, creating cost pools, and applying activity rates to products based on actual resource use.

Compare traditional costing and activity-based costing by showing how single time-based allocations distort costs; ABC uses multiple cost drivers to reflect setups, inspections, and machine use, yielding fairer product costs.

Cost drivers bridge activities and products by showing what causes each activity, with bakery oven cleaning as an example, guided by causal relationship, measurability, cost benefit, and visual impact.

Explore the four common cost driver types in activity-based costing—volume-based, transaction-based, duration-based, and intensity-based—with examples and guidance on when to apply each.

Explore activity-based costing to allocate overhead for standard brackets and custom engine molds, compute activity rates, compare ABC with traditional costing, and assess profitability.

Explore variable costing, separating variable costs (direct materials, direct labor, variable overhead) from fixed costs, understand contribution margin, and learn per-unit variable cost calculations for pricing decisions.

Explore how contribution margin reveals funds available to cover fixed costs and profit, and apply variable costing to strategic decisions, pricing, special orders, and make-or-buy choices.

Explore how variable costing affects income statement by including variable manufacturing costs in cost of goods sold, with fixed costs treated as expenses, shaping contribution margin and net operating income.

Absorption costing allocates both variable and fixed manufacturing overhead costs to each product, including factory rents and salaries, to provide a full cost view for pricing and reporting.

Compare absorption costing and variable costing, noting that absorption includes fixed and variable manufacturing costs for external reporting, while variable costing treats fixed costs as period costs for internal decisions.

Compare variable costing and absorption costing through a case study of 1000 units produced and sold, showing fixed overhead per unit and different profits.

This case compares absorption costing and variable costing when 1000 units are produced and 800 sold, showing higher profit under absorption due to fixed overhead allocated to inventory.

Case study shows units produced equal to units sold, with variable cost per unit $5, selling price $35, and fixed overhead $20,000; profits remain the same under both methods.

Explore budgeting basics and variance analysis, detailing how budgets project revenue and expenses, guide strategic planning, and benchmark performance across operation, capital, fixed, and flexible budgets.

Explain how to build an operation budget for the coming year, starting with the sales budget and linking revenue, costs, and cash flow to departments, materials, labor, overhead, and marketing.

Explore capital budgets as strategic financial planning for long-term investments, applying net present value, internal rate of return, payback period, and profitability index to select value-rich projects.

Explore variance analysis by comparing actual results to budgets, assess total, price, and other variances, and learn to take corrective actions for future planning.

Assess material variance by comparing actual and standard material costs, and analyze price and quantity variances to reveal purchasing, supplier changes, market fluctuations, and production efficiency.

Explore labor variance analysis by comparing actual and standard wage rates and hours, computing labor rate variance and labor efficiency variance to assess hiring decisions, wage negotiations, and productivity.

Explore overhead variance concepts, including fixed overhead variances (spending and volume) and variable overhead variances (spending and efficiency) with actual, budgeted, and standard variable overhead rate.

Explore the material price variance formula and labor variances in cost accounting, learn how to interpret actual versus standard costs, and analyze practical cases to explain variances.

Apply cost variance analysis to a chair factory, using Excel cases, by comparing standard and actual data for materials, labor, and overhead to compute price, quantity, and efficiency variances.

Explore sales variances through a concrete example, calculating price variance, volume variance, and contribution margin variance using standard and actual values. Identify unfavorable outcomes when actual results fall short.
