Opinion for the Court filed by DAVIS, Judge.
Appellants are federal employees who have received retroactive promotions and back pay because they were victims of sex discrimination prohibited by the Equal Employment Opportunity Act of 1972, Pub.L. No.92-261, 86 Stat. 103. 1 The issue is whether their back pay awards should have reflected an award of prejudgment interest or should have been adjusted by an inflation factor to account for the decline of the purchasing power of the dollar between the time of the discrimination and the time of the award. In the District Court, on cross-motions for summary judgment on this point, Chief Judge Bryant held that the court did not have authority to order the United States to pay either prejudgment *893 interest or a sum in addition to back pay to reflect inflation. We affirm.
The plaintiffs are five women who were employed as nursing assistants at the Clinical Center, National Institutes of Health. They brought this sex-discrimination action in March 1976, but no trial on the merits was held in the District Court. As the result of administrative decision or agreement of the parties, it was determined that they had each been denied promotion from a GS-4 to a GS-5 position as the result of sex discrimination. The parties settled the complaint that they were also discriminated against in consideration for promotion from GS-3 to GS-4. By the winter of 1976 each of the plaintiffs had received retroactive promotion and back pay. 2 The only question remaining for decision by the District Court was that now before us — addition of prejudgment interest or, alternatively, of an inflation factor.
Without such a supplement, appellants say, their awards give them an incomplete remedy, especially in view of the considerable time elapsed since their injuries occurred (see note 2, supra). They note that prejudgment interest has been awarded by some courts under Title VII in private-sector cases, 3 and urge that to deny this remedy to federal employees is to relegate them to second-class status. They argue that the automatic preclusion of an award of interest or an adjustment for inflation is contrary to the remedial provision of Title VII referring to “any other equitable relief as the court deems appropriate,” 4 as well as to the Congressional purpose, in adopting the Equal Employment Opportunity Act of 1972, to extend the protections of Title VII to federal personnel.
We take the other view because (a) there is a long-established, deeply-imbedded principle that interest is not allowed on monetary claims against the Federal Government unless Congress (or a contract) plainly authorizes such an addition, 5 and (b) in the light of this traditional doctrine we are not persuaded by the text, legislative history, or purposes of the 1972 extension of Title VII to federal workers that Congress has provided for this kind of relief to such employees.
There is no doubt as to the historical existence of an entrenched immunity of the Government from prejudgment interest, in the absence of authorization by Congress (or, in the case of a contract, the contracting parties). The Supreme Court has reiterated it many times for about a century.

See Tillson v. United States,
For this case it makes no difference whether one phrases this firmly-established rule as calling in all cases for some specific or express legislation authorizing interest
(see, e. g., United States v. Thayer-West Point Hotel Co.,
The same result must be reached for appellants’ alternative contention that they are entitled to increases in their back-pay awards to compensate for the loss of the dollar’s value due to inflation. We assume
arguendo
that interest and an inflation adjustment are distinct remedies,

but the settled governmental immunity from interest counsels against this similar supplementation (in the absence of clear Congressional authorization). Both interest and an inflation adjustment serve the same general end of compensating the recipient for differences in the worth of her award between the date of actual receipt and the date as of which the money should have been paid. If one is barred the other should also be; the same considerations govern.

Notes
. Section 11 of the Act added section 717 to Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e et seq. (1976). References to Title VII are to that Title as amended by the 1972 Act.
. According to the stipulation of the parties, appellants were entitled to and received back pay from the following dates:
a. Appellant Blake, August 22, 1971;
b. Appellant Hines, July 13, 1971;
c. Appellant Hill, January 12, 1969;
d. Appellant Jordan, November 2, 1969;
e. Appellant Riddle, April 20, 1970.
.
See, e. g., Chastang v. Flynn and Emrich Co.,
. 42 U.S.C. § 2000e-5(g) reads in pertinent part:
If the court finds that the respondent has intentionally engaged in or is intentionally engaging in an unlawful employment practice charged in the complaint, the court may enjoin the respondent from engaging in such unlawful employment practice, and order such affirmative action as may be appropriate, which may include, but is not limited to, reinstatement or hiring of employees, with or without back pay * * *, or any other equitable relief as the court deems appropriate (emphasis added).
. Only an “apparent exception” is the allowance in inverse eminent domain cases of interest as part of the constitutional measure of just compensation.
Smyth v. United States,
. Appellants point out that, in terms, this statute is limited to cases in the Court of Claims, and on that ground seek to distinguish the Supreme Court opinions cited above in the text, most of which were rendered in cases coming from the Court of Claims. But in construing this statutory limitation or its predecessors, the Supreme Court has invariably indicated that it is merely a legislative embodiment of the traditional legal rule.
E. g. Tillson,
. An old Attorney General’s opinion (on which appellants rely) puts it this way: “if Congress intend a party shall have interest, it can say so; and, unless it be said expressly, they must be words of very potent implication, which contradict effectually the general doctrine of the Government.” [7 Op. Att’y Gen. 523, 528 (1855)] (emphasis added).
. In extending Title VII to federal employees, Congress contemplated that there could be differences between the cases of private-sector employees and of federal workers. 42 U.S.C. § 2000e-16(d) (added by the 1972 Act) provides that “[t]he provisions of section 2000-5(f) through (k) of this title, as applicable, shall govern civil actions brought hereunder” (emphasis added).
. To prove this distinction, appellants offered the deposition of Patrick Jackman, chief of the Branch of Consumer Price Indexes of the United States Department of Labor. He seems to conclude that an inflation adjustment and interest are conceptually different, but are, as a practical matter, interrelated. Because of the disposition we make in this case, we need not attempt to solve this subtle economic puzzle.
