Cost Principles Under 2 CFR 200

The Rules That Determine What Grant Money Can Pay For

Every dollar of federal grant funding comes with a condition: it must be spent in accordance with the Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards — codified as 2 CFR Part 200, commonly called the Uniform Guidance. Subpart E of this regulation establishes the cost principles that govern what is allowable, how costs must be documented, and what happens when the rules are violated. These are not guidelines. They are binding requirements. Organizations that treat them as suggestions discover this during audits, when questioned costs become disallowed costs and disallowed costs become repayment obligations.

The cost principles are the most frequently misunderstood component of federal grants administration. Not because they are obscure — they are publicly available, extensively annotated, and well-documented in federal guidance — but because they require operational discipline that most grant recipients have never built. Writing a successful grant application requires narrative skill. Spending grant money correctly requires financial controls, time tracking systems, procurement documentation, and allocation methodologies that must be in place before the first dollar is spent. The gap between winning a grant and properly administering one is where most audit findings originate.

This is not an academic problem. The HHS Office of Inspector General reports questioned costs in the hundreds of millions annually across HRSA, SAMHSA, and CMS-funded programs. The most common findings are not fraud. They are administrative failures: costs charged to the wrong award, personnel costs without adequate time documentation, equipment purchased without prior approval, and subrecipient relationships misclassified as contracts. These are organizations that intended to comply and failed — not because they lacked good faith, but because they lacked the systems to operationalize the rules.

The Four-Part Allowability Test

Section 200.403 of the Uniform Guidance establishes the general standard for allowability. A cost charged to a federal award must satisfy all four conditions. Not three. All four. Failure on any single condition renders the cost unallowable.

1. Necessary and reasonable (200.403(a), 200.404). The cost must be necessary for the performance of the award and reasonable in amount. Reasonableness is evaluated by the “prudent person” standard: would a prudent person, in the same circumstances, pay this amount for this purpose? This is not a mathematical test. It is a judgment standard — and it is the standard auditors apply. A $200 conference registration fee for a staff member presenting on grant-related work is reasonable. A $2,500 conference registration fee for a staff member with no presenting role, no documented learning objective tied to the grant, and no travel approval on file is not. The distinction is not the dollar amount alone. It is the relationship between the expenditure, the purpose, and the circumstances.

The prudent person test also governs vendor selection. Paying $150/hour for a consultant when comparable consultants charge $80-100/hour requires documented justification — sole source procurement documentation, specialized expertise not available at market rate, or a competitive procurement process that resulted in the higher rate. “We always use this vendor” is not a justification that survives audit.

2. Allocable to the award (200.405). A cost is allocable to a federal award if the goods or services involved are chargeable to the award in accordance with the relative benefits received. If a staff member works on three grants and general administration, their salary must be allocated proportionally — not charged entirely to whichever grant has the most remaining budget. This is where effort reporting becomes critical: the allocation must reflect actual activity, not budgeted activity. An organization that budgets a clinical director at 40% on Grant A but discovers mid-year that the director is spending 60% of their time on non-grant clinical work has a problem. Continuing to charge 40% to the grant when actual effort is 40% is correct. Charging 40% when actual effort is 25% is an allocability violation.

The allocability requirement has a corollary that catches organizations off guard: costs that benefit multiple awards or activities must be allocated on a reasonable and consistent basis. Shared space, shared equipment, shared administrative staff — all must be allocated using a methodology that is documented, defensible, and applied uniformly. Ad hoc allocation — charging a shared cost to whichever grant has budget room — is the most common allocability failure pattern.

3. Consistent with policies applied uniformly to both federal and non-federal activities (200.403(c)). An organization cannot have one travel policy for grant-funded travel and a different, more generous policy for non-grant travel. If the organization’s travel policy caps hotel reimbursement at the federal per diem rate, that cap applies to everyone. If the organization allows first-class air travel for executives using unrestricted funds but restricts grant-funded staff to coach, the inconsistency creates audit exposure — not because first-class travel is inherently unallowable (though it generally is under 200.474), but because the inconsistency violates the uniformity requirement.

This principle extends to compensation. If the organization pays market-rate salaries to non-grant staff but inflates salaries for grant-funded positions because “the grant can pay for it,” the inconsistency violates 200.403(c). Compensation charged to federal awards must be consistent with the organization’s established compensation practices for comparable roles — regardless of funding source.

4. In conformance with the terms and conditions of the award (200.403(e)). Every award has a notice of award, terms and conditions, and frequently an approved budget with line-item detail. Costs must conform to these specific terms, not just to the general cost principles. If the award terms prohibit international travel, international travel is unallowable regardless of how reasonable or well-documented it is. If the approved budget includes $50,000 for equipment and the organization wants to spend $80,000, a budget modification is required — spending the extra $30,000 without approval violates the award terms even if the equipment is necessary and properly procured.

Prior approval requirements deserve particular attention. Section 200.407 lists specific cost items that require written prior approval from the federal awarding agency. These include equipment purchases exceeding the organization’s capitalization threshold (or the federal threshold of $5,000 under 200.1), participant support costs, foreign travel, and pre-award costs. Prior approval means approval before the expenditure, not after. Retroactive approval is not guaranteed and is never assumed.

Cost Categories That Generate Findings

Four cost categories account for a disproportionate share of OIG audit findings in healthcare grants. Each has specific regulatory requirements that go beyond the general allowability test.

Compensation and Effort Reporting (200.430)

Personnel costs are the largest line item in most healthcare grants — typically 60-80% of direct costs. They are also the most complex to document correctly. Under 200.430, charges for salaries and wages must be based on records that accurately reflect the work performed. These records must be supported by a system of internal controls that provides reasonable assurance that the charges are accurate, allowable, and properly allocated.

The critical operational requirement is effort documentation. When an employee works on multiple activities — a common situation in healthcare, where a single clinician may bill to a federal grant, a state contract, Medicaid services, and unrestricted clinical revenue — the organization must document actual effort distribution. The prior standard (OMB Circular A-21 for universities, A-87 for state and local governments) required specific effort certification reports. The Uniform Guidance relaxed the methodology requirement but not the outcome: the organization must have a system that produces records meeting the standards in 200.430(i), including after-the-fact confirmation that charges are based on actual work performed.

Fringe benefit allocation follows the same logic. If fringe rates differ across employee classes or funding sources, the allocation must be documented and consistently applied. Charging a 35% fringe rate to the grant when the organization’s actual rate for comparable employees is 28% creates a questioned cost for the 7% differential — even if the grant budget was approved at 35%.

Travel (200.474)

Grant-funded travel must be necessary and reasonable, consistent with the organization’s travel policy, and in conformance with federal limits. Commercial air travel is limited to coach class unless one of the specific exceptions in 200.474(b) applies (disability, medical need, or cost savings from a non-refundable business-class fare versus a refundable coach fare with change fees). Lodging and per diem are governed by the federal rates published by GSA (continental US) or the State Department (international). Organizations can use lower rates but cannot exceed federal rates without documented justification.

The most common travel finding is not egregious spending. It is inadequate documentation: travel vouchers without receipts, per diem claims without trip itineraries, conference registrations without documented relevance to the award purpose, and airfare without evidence that coach class was used or that an exception applied. Each missing document creates a questioned cost for the entire trip — not just the undocumented portion.

Equipment (200.439, 200.1)

Equipment is defined under 200.1 as tangible personal property with a useful life of more than one year and a per-unit acquisition cost that equals or exceeds the lesser of the organization’s capitalization threshold or $5,000. Items below this threshold are supplies, not equipment, and are treated differently for accounting, reporting, and disposition purposes.

Equipment purchases from grant funds require prior approval under 200.439 unless the specific equipment was included in the approved budget. Title to equipment acquired with federal funds vests in the recipient, but the federal awarding agency retains a conditional interest — meaning the equipment must be used for the authorized purpose, tracked in an equipment inventory, and properly disposed of at the end of the grant (200.313).

The common failure mode is purchasing items that meet the equipment definition without recognizing the prior approval and tracking requirements. An organization that buys ten iPads at $600 each treats them as supplies ($6,000 total, but each unit is below $5,000). An organization that buys a $7,000 patient monitoring system has purchased equipment and must obtain prior approval, tag the asset, include it in the annual inventory, and address disposition at closeout. Organizations that skip these steps create audit findings — not because the purchase was unreasonable, but because the procedural requirements were not followed.

Subawards vs. Contracts (200.330-332)

The distinction between a subaward and a contract is one of the most consequential classifications in grants administration, and one of the most commonly wrong. Under 200.330 (redesignated as 200.331 in the 2024 revision), the determination depends on the substance of the relationship, not the label on the agreement:

A subaward passes through federal funds to a subrecipient who carries out a portion of the federal program. The subrecipient has programmatic decision-making responsibility, is responsible for adherence to federal requirements, and uses the funds to carry out a program for a public purpose. Subawards carry monitoring obligations under 200.332: the pass-through entity must evaluate subrecipient risk, establish reporting requirements, and monitor performance.

A contract is for the procurement of goods or services needed to carry out the program. The contractor provides goods or services as part of its normal business operations, operates in a competitive environment, and does not have programmatic authority over how the federal program is designed or delivered.

The stakes of misclassification are significant. If an organization classifies a subrecipient relationship as a contract, it avoids the monitoring and reporting requirements of 200.332 — but the obligations still exist. An auditor who reclassifies the relationship as a subaward will find that no risk assessment was performed, no monitoring plan was established, and no subrecipient audit reports were obtained. The finding is not that the work was unnecessary — it is that the compliance infrastructure was absent.

Healthcare Application: An FQHC Managing a SAMHSA CCBHC Grant

Consider a Federally Qualified Health Center that receives a two-year, $2M SAMHSA Certified Community Behavioral Health Clinic (CCBHC) demonstration grant. The grant funds behavioral health integration: hiring clinical staff, purchasing health IT, and expanding access to crisis services. Three cost principle violations occur in the first year — each representing a different failure mode, each carrying different consequences.

Violation 1: Allocability failure on personnel costs. The FQHC’s Clinical Director oversees both the CCBHC grant program and the organization’s existing primary care operations. The grant budget allocates 40% of the Clinical Director’s salary ($52,000 of a $130,000 salary) to the CCBHC award. In practice, the Clinical Director spends approximately 25% of their time on CCBHC activities and 75% on non-grant clinical operations — a shift driven by a primary care staffing crisis that demanded their attention. The FQHC continues charging 40% to the grant because “that’s what the budget says.”

The consequence: $19,500 in questioned costs (the difference between 40% and 25% of salary, annualized). The time distribution records — to the extent they exist — do not support the charges. Under 200.430, charges must reflect actual effort. The budget is a plan, not a permission structure. When actual effort diverges from the budget, the charges must follow the actuals, and the organization should request a budget modification if the change is expected to persist. Failing to adjust creates a questioned cost that is straightforward for auditors to identify: compare the time records to the charges, calculate the difference.

Violation 2: Equipment rules on technology purchases. The FQHC purchases 15 iPads ($750 each, total $11,250) for patient intake and screening in the new CCBHC clinic area. Each iPad is below the $5,000 equipment threshold — these are supplies, and the purchase is properly treated. But the FQHC also purchases a behavioral health EHR module and associated server infrastructure for $38,000. This exceeds the equipment threshold, was not itemized in the approved budget (which listed “health IT” as a $40,000 line item without specifying the purchase), and was acquired without prior written approval from SAMHSA.

The consequence: $38,000 in potentially disallowed costs. The purchase may have been entirely reasonable and necessary — CCBHC programs require integrated health IT — but the absence of prior approval for an equipment-class purchase violates 200.439 and the award terms. SAMHSA may approve the cost retroactively if the FQHC can demonstrate necessity and reasonableness, but retroactive approval is discretionary, not guaranteed. The corrective action requires the FQHC to establish a procurement review process that flags purchases above the equipment threshold for prior approval before the purchase order is issued — not after the equipment is installed.

Violation 3: Subaward misclassification. The FQHC engages a behavioral health software vendor to develop and maintain a custom crisis screening tool integrated into the EHR. The agreement is structured as a contract — procurement of a technology service. However, the vendor also provides clinical decision support content, determines the screening protocols embedded in the tool, trains FQHC clinical staff on behavioral health screening methodology, and reports outcome data directly to SAMHSA as part of the CCBHC demonstration evaluation. The vendor is exercising programmatic judgment over a component of the federal program.

The consequence: an audit finding requiring corrective action. The relationship has the characteristics of a subaward under 200.330 — the vendor is carrying out a portion of the CCBHC program, making programmatic decisions, and reporting to the federal agency. By classifying the relationship as a contract, the FQHC has failed to perform a subrecipient risk assessment (200.332(b)), establish subaward terms that include federal requirements (200.332(a)), monitor the subrecipient’s programmatic and financial performance (200.332(d)), and verify whether the subrecipient requires a Single Audit (200.501). The corrective action plan requires retroactive risk assessment, reclassification of the agreement, establishment of monitoring procedures, and potentially a management decision on costs incurred without proper oversight.

The Documentation Standard

The cost principles operate on a principle that grants administrators summarize as: if it is not documented, it did not happen. This is not hyperbole. Under 200.302 and 200.403, every cost charged to a federal award must be supported by documentation sufficient to demonstrate that the cost was incurred, that it was necessary for the performance of the award, that it was allocable in accordance with documented methodology, and that it conformed to the award terms.

The documentation chain connects the expenditure to the award purpose through a traceable sequence: the purchase was authorized by someone with spending authority on the award, the goods or services were received, the cost was reviewed for allowability before being charged, and the accounting records reflect the correct award, cost category, and period. Breaking any link in this chain — an unsigned purchase order, a missing receiving report, a cost charged to the wrong budget period — creates a questioned cost.

For personnel costs, the documentation requirement is ongoing: time and effort records must be maintained for every pay period, for every employee whose salary is charged in whole or in part to a federal award. For travel, documentation means receipts, itineraries, trip reports, and evidence of federal per diem compliance. For equipment, it means purchase authorization, competitive procurement documentation (or sole source justification), asset tagging, annual inventory, and disposition records at closeout.

Organizations that build documentation into their operational workflows — capturing evidence at the point of activity — spend far less time on audit preparation than organizations that reconstruct documentation after the fact. The difference is structural: point-of-activity documentation is a byproduct of doing the work; after-the-fact reconstruction is a separate project that competes for the same staff time that should be delivering program services.

Pre-Award Costs

Section 200.458 addresses a specific and risky category: costs incurred before the federal award date. Pre-award costs are allowable if they were included in the approved budget and incurred within 90 days before the award’s effective date. The costs must meet all other allowability requirements — necessary, reasonable, allocable, consistent, and conforming.

The risk is asymmetric. An organization that incurs pre-award costs is spending its own money on the assumption that the federal award will materialize. If the award is made, the pre-award costs are reimbursable. If the award is not made — or is made at a reduced amount that does not cover the pre-award expenditures — the organization absorbs the cost with no recourse. For organizations with thin operating margins, as is typical of FQHCs and community behavioral health providers, pre-award spending creates liquidity risk. Hiring a clinician in anticipation of a HRSA grant that does not materialize means the organization is now carrying a salary obligation funded from operating reserves it may not have.

The 90-day window is a ceiling, not a safe harbor. Costs incurred within 90 days are eligible for reimbursement, but the federal agency can still disallow them if they fail the general allowability test. Starting a $200,000 construction project 89 days before the award date, when the organization had no reasonable basis to expect the award, is not protected by the 90-day provision.

Warning Signs

These indicators suggest an organization’s cost principle compliance is deteriorating or was never adequate:

• Personnel charges to grants are based on budgeted percentages rather than actual effort documentation — the single most common finding in healthcare grant audits
• Equipment purchases are processed through standard procurement without a threshold check for prior approval requirements
• Travel reimbursements exceed federal per diem rates without documented justification in the travel file
• Vendor relationships are classified as contracts or subawards based on the document title rather than an analysis of the relationship characteristics under 200.330
• Shared costs are allocated to whichever grant has remaining budget rather than using a consistent, documented allocation methodology
• Pre-award spending occurs without board-level risk acceptance and documented connection to the anticipated award budget
• Cost allowability review happens during audit preparation rather than before the purchase order is issued
• The grants team and the finance team operate independently — costs are charged without grants staff review, or grants staff approve spending without finance verification

Integration Points

PF Module 3: Compliance and Control Frameworks (03-compliance-foundations.md). Cost principles are the substantive foundation of the compliance framework. Module 3 addresses the control systems — segregation of duties, audit trails, exception management — that operationalize compliance. But the controls are only meaningful if the organization understands what it is controlling for. Cost principles define the “what”: what is allowable, what requires documentation, what demands prior approval. The compliance framework defines the “how”: how the organization ensures those rules are followed in daily operations. An organization with robust controls but poor understanding of cost principles will have well-documented violations. An organization that understands cost principles but lacks controls will have good intentions and no evidence.

WF Module 6: Workforce Economics and Capacity Planning (06-cost-of-turnover.md, 06-agency-and-overtime.md). Compensation costs are the most complex cost category under 200.430 because they require continuous effort documentation for employees who work across multiple activities. When workforce instability — turnover, vacancy, overtime — disrupts planned staffing patterns, the effort allocation changes. A grant-funded position filled by overtime from non-grant staff, or by an agency clinician whose cost structure differs from the budgeted employee, creates both a cost principle issue (is the replacement cost allowable and allocable at the rate charged?) and a workforce economics issue (what is the true cost of the staffing disruption?). The workforce frameworks in Module 6 quantify the cost; the cost principles in this page determine whether the grant can absorb it.

Product Owner Lens

What is the funding/compliance/execution problem? Grant recipients misunderstand or fail to operationalize cost principles, resulting in questioned costs, disallowed expenses, and audit findings that consume administrative capacity, threaten future funding, and divert attention from program delivery.

What mechanism explains the operational bottleneck? Cost principles require four simultaneous conditions (reasonable, allocable, consistent, conforming) supported by continuous documentation — but most organizations review allowability retroactively during reporting or audit preparation rather than prospectively at the point of expenditure. The gap between when the cost is incurred and when it is reviewed for allowability is where violations accumulate undetected.

What controls or workflows improve it? Pre-expenditure allowability review embedded in the procurement and hiring workflow. Automated effort reporting tied to payroll and time systems. Equipment threshold alerts in the purchasing system. Subaward/contract classification checklists applied at the agreement stage, not at audit.

What should software surface? A cost allowability checkpoint integrated into the purchase request workflow — before the PO is issued, the system validates that the cost category is allowable under the award terms, that prior approval has been obtained if required, that the vendor relationship is correctly classified, and that supporting documentation is attached. For personnel costs, a monthly effort reconciliation that compares budgeted allocation to actual time records and flags variances exceeding a threshold (e.g., 5 percentage points) before the payroll charges post. For equipment, an automated threshold check that routes purchases above the capitalization limit to the grants administrator for prior approval processing.

What metric reveals risk earliest? The variance between budgeted and actual effort allocation by person by award, tracked monthly. When actual effort diverges from budgeted allocation by more than 10% for two consecutive months without a budget modification, the organization is accumulating questioned cost exposure at a rate that compounds with every pay period. This is the earliest detectable signal — it precedes the audit finding by months or years, but it is visible in the payroll data from day one.
