Fixed-Price with Economic Price Adjustment (FP-EPA)

A Fixed-Price with Economic Price Adjustment (FP-EPA) contract establishes a base fixed price with a defined contractual mechanism that allows the price to be adjusted up or down when specified economic conditions, such as labor cost changes or material price index movements, occur during performance.

What is a Fixed-Price with Economic Price Adjustment Contract?

FP-EPA is defined in FAR 16.203 and is used when there is serious doubt about the stability of market or labor conditions over the contract period. Rather than requiring the contractor to absorb potentially large economic fluctuations in a pure fixed price, or giving the government unlimited exposure through cost reimbursement, FP-EPA splits the economic risk through a predefined adjustment formula.

FAR 16.203 identifies three types of economic price adjustments:

Type 1, Established prices: The contract price is tied to a specific published catalog or market price. If the vendor's commercial catalog price changes, the contract price adjusts accordingly. Used for commercial products where price changes are public and verifiable.

Type 2, Labor or material cost indices: The contract price adjusts based on a published index, the Consumer Price Index, the Employment Cost Index, the Producer Price Index, or a commodity-specific index. The adjustment is applied to the portion of the price affected by the index.

Type 3, Actual labor or material costs: The contract price adjusts based on actual changes in the contractor's labor rates or material costs, typically demonstrated through certified payroll or material invoices. This is the most administratively intensive type.

Key design elements of an EPA clause:

• Adjustment trigger: the threshold (often 3-5%) below which no adjustment is made
• Adjustment ceiling: the maximum adjustment allowed over the contract life
• Adjustment period: when adjustments can be requested (annually, at option exercise, etc.)
• Downward adjustment: most EPA clauses allow both upward and downward adjustments

Why FP-EPA matters for government contractors

FP-EPA is most valuable for multi-year service contracts where labor is the dominant cost and wage escalation is unpredictable. A five-year service contract without an EPA clause requires the contractor to build escalation assumptions into the price at award, either underestimating and losing money if wages rise faster, or overestimating and losing the competition to a lower-priced competitor. An EPA clause shifts this risk to a shared, formula-based mechanism. For contractors bidding on multi-year service contracts, advocating for an EPA clause, or structuring the price to account for likely escalation, is essential to long-term contract profitability.

Example

A facilities management company wins a 5-year base contract with four option years for building maintenance at a federal complex. The contract includes an FP-EPA clause tied to the Employment Cost Index for the appropriate labor category. In year 3, the ECI increases 4.2%, above the 3% adjustment trigger. The contractor submits an EPA adjustment request with the relevant index data. The contracting officer verifies the calculation and approves a 1.2% price adjustment (4.2% increase minus the 3% trigger threshold). Without the EPA clause, the contractor would have absorbed the full wage increase against the original fixed price.

Frequently Asked Questions

Can an FP-EPA adjustment be downward?

Yes. Most EPA clauses work in both directions. If the relevant index decreases, the contract price may be reduced. This symmetry protects the government when economic conditions improve and ensures the mechanism truly reflects market conditions rather than ratcheting only upward.

Does an EPA clause require a contract modification?

Yes. Each EPA adjustment must be processed through a contract modification signed by the contracting officer. The adjustment is not automatic, the contractor (or in the case of downward adjustment, the government) must submit a request with supporting data, and the contracting officer must verify the calculation before modifying the contract price.

Are EPA clauses common in commercial item contracts?

Type 1 EPA (catalog price adjustment) is common in commercial item contracts where the vendor's published price list is the basis for the contract price. Types 2 and 3 are more common in long-term service and construction contracts where labor and material costs are the primary economic variables.

What is the difference between an EPA clause and an option year price escalation?

An EPA clause adjusts prices automatically based on a formula tied to external economic indices. An option year price escalation is a negotiated fixed percentage (e.g., 3% per year) built into the option year pricing at contract award. EPA clauses reflect actual economic changes; option year escalation reflects negotiated estimates. EPA clauses provide more accurate price adjustment but require more administrative effort.
