Allocability

Allocability is one of the three cost-principle tests a US federal award recipient must satisfy before charging a cost to a federal grant or cooperative agreement under 2 CFR Part 200 (Uniform Guidance) — alongside allowability (§200.403) and reasonableness (§200.404). A cost can be perfectly reasonable in amount and otherwise allowable in kind, and still fail the allocability test if it cannot legitimately be assigned to the specific award being charged.

Operational definition

Under §200.405 of 2 CFR Part 200, a cost is allocable to a federal award if it is assignable to that award in accordance with the relative benefits received. This standard is met when a cost satisfies any one of three conditions:

1. Incurred specifically for the award. The cost exists only because of the award — for example, a reagent purchased solely to run an assay specified in the award’s scope of work.
2. Benefits both the award and other work, in proportions that can be reasonably determined. The cost supports multiple projects or activities, but the institution can approximate the relative benefit to each using a reasonable, documented method (e.g., square footage for a shared lab space, or percentage effort for a staff member split across two awards).
3. Necessary to the overall operation of the organization and assignable to the award in accordance with the applicable cost-accounting principles. This covers costs that support the institution broadly (and therefore cannot be traced to one project) but are still properly assignable to the award through an approved indirect cost allocation methodology rather than direct charging.

§200.405 also states the reverse constraint that governs most allocability audit findings: a cost allocable to one federal award may not be shifted to a different federal award — whether to cover a funding shortfall, avoid a restriction, or absorb an unspent balance before a project period closes. This is why allocability questions surface most often at year-end or project closeout, when institutions are tempted to move costs onto an award with remaining budget rather than the award that actually benefited from them.

How allocability differs from allowability and reasonableness

2 CFR 200 Subpart E treats allowability, reasonableness, and allocability as related but distinct tests, and a cost generally must clear all three (plus consistency of treatment) before it can be charged to a federal award:

• Allowability (§200.403) asks whether a cost is permitted at all under the applicable cost principles and the award’s own terms — is this type of cost allowed, is it treated consistently with how the institution treats similar costs elsewhere, does it conform to GAAP, and is it adequately documented? Allocability is itself one of the criteria §200.403 lists for allowability, which is why the two are so often discussed together — a cost cannot be allowable unless it is also allocable, but a cost can be allocable without being allowable (for example, a cost the award’s terms and conditions specifically exclude).
• Reasonableness (§200.404) asks whether the amount of the cost reflects what a prudent person would have paid under the circumstances prevailing when the decision to incur it was made — the “prudent person” standard. Reasonableness is about magnitude and judgment, not assignment.
• Allocability (§200.405) asks whether the cost can be assigned to this particular award, as opposed to another award, another activity, or general institutional overhead — the question addressed above.

A useful shorthand: allowability asks “is this kind of cost permitted,” reasonableness asks “is the amount defensible,” and allocability asks “does it belong on this award.” All three sit inside the same Subpart E framework alongside the consistency requirement, and a federal audit finding frequently cites more than one of them together — a cost shifted late in a project period to absorb unspent budget, for instance, typically fails allocability even if the underlying expense would have been both reasonable and allowable had it been charged to the award that actually benefited from it.

Worked examples

Example 1 — condition (1), incurred specifically for the award. A specialized antibody purchased only because a specific federal award’s aims require it, used exclusively on that project’s samples, is allocable to that award outright — it satisfies the award-specific condition directly.

Example 2 — condition (2), reasonably determinable proportional benefit. A postdoctoral researcher splits their effort across two federal awards. Their salary is allocable to each award in proportion to the percentage of effort actually certified against it (via effort reporting), not in whatever proportion is administratively convenient.

Counter-example — fails allocability despite being otherwise allowable and reasonable. Near the end of a federal award’s project period, an institution has unspent budget on Award A and a legitimate, reasonably priced piece of equipment it wants for a researcher who is also working on Award B, which has no remaining budget. Charging that equipment to Award A because it has funds available — rather than because Award A’s scope of work actually benefits from it — is exactly the cost-shifting §200.405 prohibits: the equipment cost is not allocable to Award A regardless of how reasonable its price was or how allowable that category of cost would otherwise be.

Why it matters for research administration

Allocability is a routine subject of Single Audit findings (under 2 CFR Part 200 Subpart F) and internal-controls reviews because it depends on institutional judgment and documentation rather than a fixed dollar threshold — unlike, say, a supplies capitalization limit. Sponsored-programs offices typically operationalize allocability through documented cost-allocation methodologies (e.g., an approved space-and-effort survey for indirect costs, or a subaward’s own certified effort report for a shared salary line), because “reasonably determined proportional benefit” under condition (2) has to be demonstrable on audit, not just asserted after the fact. This is also the direct link between allocability and an institution’s negotiated indirect cost rate (F&A rate): costs that are allocable to an award under condition (3) — necessary to the organization’s overall operation but not traceable to one project — are exactly the category of cost recovered through the indirect cost rate rather than direct-charged.

Related terms

• Uniform Guidance (2 CFR 200) — the umbrella framework Subpart E’s cost principles sit inside.
• Direct costs — costs charged directly to an award, which must independently satisfy allocability.
• Direct charging — the practice of assigning a cost directly to an award rather than recovering it through the indirect cost rate.
• Indirect Cost Rate (F&A Rate) — how costs allocable under condition (3) are typically recovered.
• MTDC (Modified Total Direct Cost) — the base to which an F&A rate is applied.
• Cost reimbursement — the funding model under which allocability, allowability, and reasonableness are actively tested at the point of each charge.
