CMA Cost Allocation and Pricing Decisions Explained

CMA cost allocation assigns support department costs to the operating departments and products that use them, and pricing decisions then use those full costs to set a price that covers cost and earns a profit. Managers allocate support costs with a fair base, such as machine hours or headcount. Then they price with cost-plus markup, or they work backwards from the market price with target costing. This note works through both skills with full figures.

CMA cost allocation: why support costs must be assigned

CMA cost allocation assigns service department costs, such as maintenance and human resources, to operating departments using a fair allocation base. The goal is a full product cost that supports pricing, performance review, and make-or-buy decisions, so managers never price from direct cost alone.

Operating departments earn revenue. Support departments do not. However, products still consume support services. For example, machines need maintenance, and workers need hiring and payroll support. Therefore, leaving support costs unassigned understates product cost and overstates profit. In contrast, a sensible allocation gives managers a full cost they can trust for pricing.

Choose the allocation base first

The allocation base should reflect cause and effect. Maintenance usually follows machine hours. Human resources usually follows employee headcount. Building services often follow square footage. First, identify what drives the support cost. Then, pick the base that tracks that driver most closely. Finally, apply one consistent rate: total support cost divided by total base units.

Two rate designs matter for the exam. A single-rate method pools fixed and variable support costs into one rate. In contrast, a dual-rate method separates them: managers allocate fixed costs on budgeted capacity and variable costs on actual usage. The dual-rate method is fairer, because an operating department should not pay more fixed cost simply because another department used less capacity. Similarly, dual rates stop one department from shifting its variable cost onto others.

CMA cost allocation: the step-down method worked example

The step-down method allocates support costs in sequence. Managers rank the support departments, allocate the first one to all remaining departments, and then move on. As a result, later allocations include costs passed down from earlier steps. The method recognizes that support departments serve each other, which the direct method ignores.

Consider a company with two support departments and two operating departments. Maintenance costs $180,000. Human Resources costs $90,000. The operating departments are Machining and Assembly. Maintenance serves all three other departments, so managers allocate it first, using machine hours. Human Resources serves only the operating departments, so managers allocate it second, using employee headcount.

Support department	Total cost ($)	Allocation base	Rate
Maintenance	180,000	20,000 machine hours	$9.00 per machine hour
Human Resources	108,000	50 employees	$2,160 per employee

Apply the rates department by department

Maintenance allocates at $9.00 per machine hour. Human Resources uses 2,000 machine hours, so it receives $18,000. Machining uses 10,000 machine hours, so it receives $90,000. Assembly uses 8,000 machine hours, so it receives $72,000. The three amounts sum to $180,000, which proves the allocation.

Human Resources now carries $108,000: its own $90,000 plus the $18,000 passed down from Maintenance. Managers divide $108,000 by 50 employees and get $2,160 per employee. Machining has 30 employees, so it receives $64,800. Assembly has 20 employees, so it receives $43,200. The two amounts sum to $108,000.

Operating department	From Maintenance ($)	From Human Resources ($)	Total allocated ($)
Machining	90,000	64,800	154,800
Assembly	72,000	43,200	115,200
Total	162,000	108,000	270,000

The final totals check out. Machining absorbs $154,800 and Assembly absorbs $115,200. Together they equal $270,000, the sum of both support costs. Above all, note the order effect: managers allocated Maintenance first because it serves Human Resources. If they had reversed the order, the final totals would change, because Human Resources does not serve Maintenance.

How the step-down result differs from the direct method

The direct method skips inter-support service entirely. Under the direct method, Maintenance allocates only to operating departments: $180,000 divided by 18,000 machine hours gives $10.00 per machine hour, so Machining receives $100,000 and Assembly receives $80,000. Human Resources allocates $90,000 over 50 employees at $1,800 each, so Machining receives $54,000 and Assembly receives $36,000. The direct totals are $154,000 for Machining and $116,000 for Assembly. Compared with step-down, Machining gains $800 and Assembly loses $800. The difference looks small here, but with larger support costs it changes product costs, prices, and performance reviews. Therefore, the exam often asks candidates to explain why step-down beats direct: it recognizes real service flows between support departments.

CMA cost allocation: pricing decisions that use full cost

Allocation matters because pricing starts from full cost. Cost-plus pricing adds a markup to unit cost. The markup must cover profit and any costs the unit cost omits. First, build the unit cost from direct materials, direct labor, variable overhead, and fixed overhead. Then, apply the markup. Finally, test the price against the market: a price above what customers will pay will not sell, however carefully managers costed the product.

Take a product with direct materials of $30, direct labor of $25, variable overhead of $15, and fixed overhead of $10 per unit. The full unit cost is $80. With a markup of 25% on cost, managers add $20 and set a price of $100. This calculation is simple, and that simplicity explains its popularity. However, it hides a trap that the exam loves: markup on cost differs from markup on price. A 25% markup on price means the price must satisfy a different equation: price equals $80 divided by 1 minus 0.25, which gives $106.67. Managers who confuse the two underprice by $6.67 per unit.

Target costing works backwards from the market

Target costing reverses the logic. Instead of costing first and pricing second, managers take the market price as given and derive the cost they can afford. The formula is simple: target cost equals target price minus desired profit. For example, suppose the market price for a product is $120 and the company wants a profit of 20% of price. Desired profit is $24, so target cost is $96. If current cost is $110, managers face a cost gap of $14 per unit. They must redesign, renegotiate materials, or simplify the product to close that gap. If they cannot close it, they should not launch at that price. In contrast to cost-plus pricing, target costing forces discipline before launch, not after.

Special orders: accept only when incremental revenue beats incremental cost

Special orders test whether managers understand relevant cost. Suppose a buyer offers to take 1,000 units at $55 each, while the regular price is $100. The variable cost is $40 per unit, the company has spare capacity, and the order will not affect regular sales. Incremental revenue is $55,000. Incremental cost is $40,000. The order adds $15,000 of profit, so managers should accept it. Fixed overhead does not enter the decision, because the company incurs it whether or not it accepts the order. However, the answer flips if capacity is tight: accepting the order would then displace regular sales, and managers must count the lost contribution from those sales as an opportunity cost. Similarly, a special price that leaks into the regular market can destroy more profit than the order creates.

Exam pitfalls that cost marks

• Allocating on the wrong base. A base must track the cost driver. Machine hours suit maintenance, not headcount. A weak base produces a full cost nobody trusts.
• Forgetting the step-down order. Managers must allocate the department that serves the most other departments first. A reversed order changes every downstream figure.
• Double counting support costs. Each support dollar allocates once. After managers allocate a department, its balance must reach zero, and the operating totals must sum to total support cost.
• Mixing markup on cost with markup on price. A 25% markup on cost gives $100 on an $80 cost. A 25% markup on price gives $106.67. Read the question wording twice.
• Counting fixed cost in a special order. With spare capacity, only incremental variable cost matters. Fixed cost stays fixed, so it cannot change the decision.
• Ignoring the cost gap in target costing. A target cost is a commitment, not a wish. If current cost exceeds target cost by $14, managers must name how they will remove $14, or decline the launch.
• Using allocated cost as if it were cash. Allocated overhead is an accounting assignment, not a cash flow. Managers should never approve a cash decision, such as closing a department, on allocated cost alone.

Quick revision checklist

Before you close this topic, make sure you can do each of the following without looking back: pick an allocation base that tracks the cost driver; explain single-rate versus dual-rate allocation; run a step-down allocation and prove that operating totals sum to total support cost; explain why step-down differs from direct; price with cost-plus markup and convert between markup on cost and markup on price; derive a target cost from market price and desired profit and state the cost gap; and judge a special order on incremental revenue versus incremental cost, including the opportunity cost when capacity is tight.
