Build an economic price adjustment evidence file

Published by Federal Bid Partners LLC · October 26, 2026 · Pricing changes

An economic price adjustment request is strongest when a reviewer can reproduce the calculation. Begin with the clause and agreed EPA method that actually apply to your contract. GSAR 552.238-120 ties requests to the established method and allows the contracting officer to seek additional support or accept, reject, or negotiate the request. A cost increase alone does not establish an automatic right to a particular new price. Read GSAR 552.238-120.

Write a method card

Use one page to record the incorporated clause version, current agreed method, covered items, adjustment mechanism, timing provisions, and any applicable limits. Add the source document and page for each entry. If you cannot find the method, mark the issue unresolved and obtain clarification before building a complex pricing workbook. Do not substitute a generic online example for the agreement in your contract.

Fictional Meridian Training proposes moving a course price from $1,000 to $1,040. Its internal cost model shows higher instructor costs, but its contract's agreed method uses a specified index. The team keeps the business explanation and the contractual calculation in separate tabs. This makes the distinction visible: why management wants a change is one question; how the contract permits a change is another.

Make every number traceable

• Identify the exact approved baseline price and its unit.
• Capture the relevant source value and its publication date.
• Show the calculation in a readable line, including rounding.
• State whether the proposed change affects all items or a defined subset.
• Explain exclusions and any item-specific exceptions.
• Retain a dated copy of supporting material rather than only a changing web link.

For a purely illustrative calculation, $1,000 multiplied by 1.04 produces $1,040. This arithmetic does not establish that four percent is allowable under any real contract. Meridian's reviewer checks the input, period, rounding rule, and proposed effective date against its method. A second person repeats the calculation independently and records the result in the review note.

Keep the evidence current through negotiation

Use a change log when the requested rate or supporting information changes. Do not overwrite the original package and lose the explanation of what the contracting officer reviewed. Where GSAR 552.238-117 applies, accurate and complete pricing information matters, including relevant changes before negotiations finish. Check the clause in your contract rather than treating document preparation as a one-time event. Review GSAR 552.238-117.

Label each proposed price clearly until the executed modification establishes the approved outcome. Under 552.238-120, approved EPA requests apply to orders issued on or after the modification's effective date; the clause also addresses BPA treatment and catalog updates. Do not assume that every existing order automatically adopts a new rate. Check the effective-date provisions.

Close the loop

After execution, compare the approved rates, units, affected items, and effective date with your final proposed workbook. Record negotiated differences. Give the catalog owner and proposal team a controlled release note identifying the approved version and any unresolved questions. Retain the evidence file so a later administrator can reconstruct both the calculation and the approved result without relying on institutional memory.
