Cost Realism Analysis

Cost realism analysis is the government's evaluation of a contractor's proposed costs on a cost-type or T&M contract to determine whether the proposed costs are realistic for the work to be performed, reflect a clear understanding of the requirements, and are consistent with the contractor's proposed technical approach, conducted under FAR 15.404-1(d) to identify proposals whose costs are too low to credibly perform the work.

What is Cost Realism Analysis?

Cost realism analysis is required for cost-reimbursement contracts and is optional but common on T&M contracts. The rationale is straightforward: on a cost-type contract, the government reimburses the contractor's actual costs regardless of whether those costs exceed the proposal. A contractor that wins by proposing unrealistically low costs still receives reimbursement at actual cost, the low proposal price does not constrain what the government ultimately pays. Cost realism analysis prevents the government from choosing an offeror whose low proposal reflects inadequate understanding of the work rather than genuine cost efficiency.

The evaluator reviews each offeror's proposed costs against three benchmarks: (1) the Independent Government Cost Estimate (IGCE), whether the proposed cost is in a reasonable range of the government's own estimate; (2) historical cost experience on similar efforts, whether proposed labor hours and material costs are consistent with what similar work has cost in the past; and (3) consistency with the technical approach, whether the proposed cost is adequate to accomplish what the technical proposal promises. An elaborate, high-capability technical approach proposed at costs that would not support the promised staffing level fails cost realism.

When cost realism concerns are identified, the contracting officer makes a "most probable cost" (MPC) determination, adjusting the offeror's proposed costs upward to what the government believes the work will actually cost. The MPC, not the offeror's proposed price, is used in the best-value trade-off analysis when comparing competing offers. An offeror with a low proposed cost but a high MPC may rank below a higher-proposing offeror whose costs were deemed realistic.

Why Cost Realism Analysis Matters for Government Contractors

A proposal that passes cost realism review requires credible labor hours and rates. Cutting hours to win on cost-type contracts is a losing strategy, the government adjusts the cost upward anyway and you win with a higher MPC than you proposed. The more effective strategy is proposing realistic costs with a compelling narrative for why your approach is efficient, fewer management layers, experienced personnel who complete tasks faster, reusable tools that reduce labor. Proposing realistic costs is also ethically important: proposing hours you know are insufficient creates a performance problem once the contract begins.

Example

Four firms compete on a $25M CPFF IT modernization task order. The IGCE is $24.8M. Firm A proposes $23.1M (reasonable range of IGCE, deemed realistic). Firm B proposes $19.4M, evaluators note the proposed staff of 12 is inadequate for the 47 deliverables listed in the technical approach; MPC adjusted to $24.2M. Firm C proposes $27.8M, evaluated as unrealistically high given the technical approach; nevertheless, passes realism (cost realism focuses on too-low proposals, not too-high). Firm D proposes $22.5M with 15 staff; rates appear below market for the required clearance levels; MPC adjusted to $23.9M. Firm A wins on best value with realistic costs and a strong technical approach.

Frequently Asked Questions

Does cost realism analysis apply to FFP contracts?

Generally no. On FFP contracts, the government accepts the price as submitted and the contractor bears cost overrun risk. Price analysis techniques (comparing to market, to the IGCE, or to other offers) are used instead of cost realism analysis. The rationale: if a contractor wins an FFP contract with an unrealistically low price, it absorbs the resulting losses, the government is protected by the fixed price. Cost realism is only relevant when the government will reimburse actual costs, creating a risk that low proposals result in higher actual government expenditure than a higher-but-realistic proposal would have.

Can a contractor improve its position if MPC adjustments make it look noncompetitive?

Yes, in limited circumstances. During discussions (if the procurement includes an opportunity for discussions), the contracting officer may inform offerors of cost realism concerns and allow them to revise their proposals. Revising the technical approach to require fewer resources (genuinely reducing the realistic cost), proposing more experienced personnel who will be more efficient, or demonstrating through detailed basis-of-estimate documentation that the proposed hours are achievable can all respond to cost realism concerns. Inflating hours post-discussions without changing the technical approach raises its own questions about proposal credibility.

How is cost realism analysis documented?

The contracting officer documents cost realism determinations in the price negotiation memorandum (PNM). For each offeror reviewed, the PNM should state: the proposed cost, the analysis methodology used (comparison to IGCE, historical data, cross-offeror comparison), identified realism concerns, and the MPC determination. This documentation is critical if an unsuccessful offeror protests the award, the GAO will review the cost realism analysis to verify it was conducted in accordance with the RFP evaluation criteria and FAR 15.404-1(d) requirements.

Is cost realism the same as price reasonableness analysis?

No. Price reasonableness asks whether the proposed price is too high, whether the government is paying more than it should for the work. Cost realism asks whether the proposed cost is too low, whether the contractor will actually be able to perform at the proposed cost. Both analyses may be conducted on the same procurement (reasonableness to protect against overpaying, realism to protect against unrealistic low proposals), but they answer opposite questions using different methodologies.
