22.1 Cost Principles, Indirect Rates and Realism

Cost Analysis Methodology & Public Cost Principles

When a public agency must procure complex custom systems, specialized professional services, or sole-source technologies where no commercial market exists, the buyer cannot rely on price analysis alone. The buyer must perform a cost analysis to evaluate the vendor's underlying cost accounting.

The Three Pillars of Cost Principles

Under public cost accounting standards—codified in Federal Acquisition Regulation (FAR) Part 31, 2 CFR 200 Subpart E (Uniform Guidance), and state public purchasing statutes—a cost element is allowable only if it satisfies three foundational considerations, alongside the other applicable cost-principle conditions:

1. Allowable: A cost must not be expressly prohibited by statute, administrative rule, or contract terms. For example, federal grant rules (2 CFR 200) and state procurement laws explicitly classify alcoholic beverages, entertainment, lobbying expenses, bad debts, certain financing costs, and political contributions as unallowable costs. Unallowable costs must be stripped completely from the contractor's proposal and indirect pools.
2. Allocable: A cost is allocable if it is assignable or chargeable to one or more cost objectives in accordance with relative benefits received. A direct cost must be incurred solely for the contract. An indirect cost must benefit the contract in reasonable proportion to other agency work.
3. Reasonable: A cost is reasonable if, in its nature and amount, it does not exceed that which would be incurred by a prudent person under the circumstances prevailing at the time the decision was made. The buyer examines whether the contractor exercised sound business prudence, followed established commercial practices, and complied with statutory obligations.

Analyzing Direct vs. Indirect Cost Elements

In conducting a cost analysis, the buyer examines the contractor's itemized proposal across two fundamental cost classes:

Direct Costs

Direct costs are those that can be identified specifically with a particular final cost objective (the specific contract project):

• Direct Labor: The buyer verifies proposed job classifications (e.g., Senior Systems Architect vs. Junior Programmer), audits the proposed hours against the Statement of Work, and verifies wage rates using payroll records, historical company averages, or Bureau of Labor Statistics (BLS) wage data.
• Direct Materials: The buyer evaluates the bill of materials, verifies parts quantities, and requests copies of supplier invoices or competitive catalog quotes to confirm parts pricing.
• Subcontract Costs: The buyer reviews the contractor's selection of subcontractors, ensuring that subcontractors were selected through competitive processes or that individual cost analyses were performed on sole-source subcontracts.
• Other Direct Costs (ODCs): Specific travel, equipment leasing, or project-dedicated software tools required exclusively for contract performance.

Indirect Costs (Overhead & G&A)

Indirect costs are costs incurred for common or joint business objectives that cannot be readily identified with a single final contract. Indirect costs are accumulated into logical cost pools and allocated to contracts across an established allocation base:

• Fringe Benefits: Payroll taxes, health insurance, retirement plans, and paid leave, typically allocated as a percentage of direct labor wages.
• Operational/Manufacturing Overhead: Factory depreciation, facilities maintenance, shop utilities, and supervisory labor, allocated as a percentage of direct labor dollars or machine hours.
• General and Administrative (G&A) Expenses: Executive management salaries, corporate legal, accounting, human resources, and general corporate insurance, typically allocated across total cost input.

Public buyers verify that indirect cost rates have been audited by a cognizant government audit agency (such as the Defense Contract Audit Agency [DCAA] or a state comptroller) or require the vendor to provide certified financial statements to verify indirect rate calculations.

Cost Realism Analysis

A critical subset of cost analysis is cost realism analysis. Cost realism evaluates whether the contractor's proposed cost elements are realistic for the work to be performed, reflect a clear understanding of contract requirements, and match the specific technical approach described in the proposal.

Cost realism prevents "buy-in" bidding—a predatory practice where a vendor deliberately submits an unrealistically low cost estimate to win a cost-reimbursement or multi-year contract, intending to later claim cost overruns or seek lucrative change orders once the government is locked into the vendor's technology.
