the opinion of the Court.
Section 502 of the Foreign Relations Authorization Act, Fiscal Years 1986 and 1987, 99 Stat. 438 , note following 50 U. S. C. § 1701 (1982 ed., Supp. V), requires the Federal Reserve Bank of New York to deduct and pay into the United States Treasury a percentage of any award made by the Iran-United States Claims Tribunal in favor of an American claimant before remitting the award to the claimant. We are asked to consider in this case whether § 502 violates the Just Compensation Clause or Due Process Clause of the Fifth Amendment[1] or the Origination Clause of Article I, § 7.[2]

On November 14, 1979, President Carter issued Executive Order No. 12170, blocking the removal or transfer of all property of the Government of Iran subject to American jurisdiction. 3 CFR 457 (1980). One day later, the Secretary of the Treasury issued regulations invalidating any attachment affecting Iranian property covered by the Executive Order unless the attachment was licensed by the Secretary. 31 CFR § 535.203 (e) (1980). The regulations provided that any such license could be “amended, modified, or revoked at any time.” §535.805. On November 26, 1979, the President granted a general license authorizing judicial proceedings against Iran but not the “entry of any judgment or of any decree or order of similar or analogous effect . . . .” § 535.504(b)(1). A subsequently issued regulation made clear that the President’s license authorized prejudgment attachments. §535.418.
As part of the resolution of the diplomatic crisis, the United States and Iran entered into an agreement embodied in two declarations of the Government of Algeria commonly referred to as the Algiers Accords (hereinafter the Accords). App. 29-42. The Accords provided for the establishment in The Hague of an international arbitral tribunal, known as the Iran-United States Claims Tribunal (hereinafter the Tribunal), to hear claims brought by Americans against the Government of Iran. The establishment of the Tribunal was to
Prior to the Accords, Sperry had filed suit against Iran in the United States District Court for the District of Columbia and had obtained a prejudgment attachment of blocked Iranian assets, but the Executive Orders sustained in Dames & Moore invalidated that attachment and prohibited Sperry from further pursuing its claims against Iran in any American courts. Sperry therefore filed a claim against Iran with the Tribunal and also began settlement negotiations with Iran. In February 1982, Sperry and Iran reached an agreement requiring the payment by Iran to Sperry of $2.8 million. The Government of Iran gave the settlement final approval on July 8, 1982.
Sperry and Iran then filed a joint application with the Tribunal, which was granted, to have the settlement entered as an “Award on-Agreed Terms.” The entry of the settlement provided Sperry with a significant benefit, for it gave the settlement agreement the status of an award by the Tribunal, and under the Accords, all awards of the Tribunal are “final
We come now to the heart of this dispute. The Accords provided that “[t]he expenses of the Tribunal shall be borne equally by the two governments.” App. 41. On June 7, 1982, the Department of the Treasury issued a “Directive License” requiring the Federal Reserve Bank of New York to deduct 2% from each award certified by the Tribunal and to pay the deducted amount into the Treasury “to reimburse the United States Government for costs incurred for the benefit of U. S. nationals who have claims against Iran.” 47 Fed. Reg. 25243 (1982). When the Federal Reserve Bank of New York received Sperry’s award, it deducted the 2% charge over Sperry’s protest, deposited the charge in the Treasury, and paid Sperry the balance of its award.
Sperry filed suit in the United States Claims Court, contending that the 2% charge was unconstitutional and was not (as the United States argued) authorized by the Independent Offices Appropriation Act, 1952 (IOAA), 65 Stat. 290 , 31 U. S. C. §483a (1976 ed.).[4] The Claims Court held in an oral ruling on May 1, 1985, that the Directive License violated IOAA. App. to Juris. Statement 26a-51a. Congress reacted swiftly by enacting § 502, which specifically requires the assessment of a charge against successful American
4 Title 31 was recodified in 1982, and IOAA is now to be found at 31 U. S. C. § 9701 (1982 ed.).
Sperry renewed its challenge to the deduction in the Claims Court, arguing that the 114% deduction authorized by §502 was unconstitutional. The Claims Court rejected the constitutional claims and dismissed Sperry’s suit. 12 Cl. Ct. 736 (1987). The Court of Appeals for the Federal Circuit reversed and held that § 502 was unconstitutional as it caused a taking of Sperry’s private property without just compensation. 853 F. 2d 904 (1988). The Court of Appeals likened the 114% deduction by the Federal Reserve Bank of New York to the permanent physical occupation by the Government of private property which, this Court held in Loretto v. Teleprompter Manhattan CATV Corp., 458 U. S. 419 , 441 (1982), is always a “taking” requiring just compensation. The Court of Appeals was unmoved by the United States’ argument that there was no taking given the benefits that Sperry had obtained from the Tribunal: “[W]e do not see the benefit of the Tribunal to Sperry when prior to the Accords it had secured the attachment of Iranian assets sufficient to cover its eventual award and, had the President not suspended American claims, would have had no need for the Tribunal.” 853 F. 2d, at 908 .
The United States invoked our appellate jurisdiction under the version of 28 U. S. C. § 1252 (1982 ed.) in effect before its

Sperry argues that the deduction is a part of Congress’ scheme to shift to American claimants against Iran those costs of settling the diplomatic crisis that should have been borne by the Nation as a whole. As we see it, however, Sperry has not identified any of its property that was taken without just compensation. To the extent the Court of Appeals’ decision may be read as concluding that Sperry suffered a taking of its property because its prejudgment attachment against Iranian assets was nullified by the Executive Orders implementing the Accords, see 853 F. 2d, at 907 , that conclusion is incorrect; we held in Dames & Moore v. Regan, 453 U. S., at 674, n. 6 , that American litigants against Iran had no property interest in such attachments. Nor did Sperry suffer the deprivation of its claim against Iran. Sperry presented its claim to the Tribunal and settled the claim for a substantial sum.[6] And we note that Sperry makes no claim that the gross amount of the award was less
5 Section 1252 permitted a direct appeal to this Court from “an interlocutory or final judgment, decree or order of any court of the United States . . . holding an Act of Congress unconstitutional in any civil action, suit, or proceeding to which the United States ... is a party.” Congress eliminated most of this Court’s appellate jurisdiction, including that based on § 1252, in Public Law 100-352, 102 Stat. 662 , which was enacted on June 27, 1988. However, § 7 of Public Law 100-352 provides that the statute “shall take effect ninety days after the date of the enactment of this Act,” i. e., on September 25,1988, and shall not “affect the right to review or the manner of reviewing the judgment or decree of a court which was entered before such effective date.” Id., at 664 . The judgment of the Court of Appeals was entered on August 10,1988, before the effective date of Public Law 100-352. The appeal is therefore proper. See also Duquesne Light Co. v. Barasch, 488 U. S. 299 , 307, n. 4 (1989).
6 Sperry’s ability to pursue its claim against Iran in another forum distinguishes this case from Gray v. United States, 21 Cl. Ct. 340 (1886). In the treaty at issue in Gray, the United States canceled American claims against France altogether. Id., at 393 .
As for the deduction itself, the United States urges that it is not a taking at all but is a reasonable “user fee” assessed against claimants before the Tribunal and intended to reimburse the United States for its costs in connection with the Tribunal. Sperry responds that the § 502 charge cannot be upheld as a user fee because there has been no showing that the amount of the deduction approximates the cost of the Tribunal to the United States or bears any relationship to Sperry’s use of the Tribunal or the value of the Tribunal’s services to Sperry. None of Sperry’s submissions is persuasive.
Section 502(a) specifically states that the deductions are made as “reimbursement to the United States Government for expenses incurred in connection with the arbitration of claims of United States claimants against Iran before [the] Tribunal and the maintenance of the Security Account. . . .” Given especially this specific declaration by Congress that the deductions are intended to reimburse costs incurred by the United States, the burden must lie with Sperry to demonstrate that the reality of § 502 belies its express language before we conclude that the deductions are actually takings. Cf. Pittsburgh v. Alco Parking Corp., 417 U. S. 369 , 375-376 (1974). That burden has not been met.
This Court has never held that the amount of a user fee must be precisely calibrated to the use that a party makes of Government services. Nor does the Government need to record invoices and billable hours to justify the cost of its services. All that we have required is that the user fee be a “fair approximation of the cost of benefits supplied. ” Massachusetts v. United States, 435 U. S. 444 , 463, n. 19 (1978). In that case, the Court upheld a flat registration fee assessed by the Federal Government on civil aircraft, including aircraft owned by the States, against a challenge that the fee
7 Sperry urges, however, that American Trucking Assns., Inc. v. Scheiner, 483 U. S. 266 (1987), compels invalidation of the deduction here. In that ease, the Court rejected Pennsylvania’s argument that flat truck registration fees and axle taxes did not violate the Commerce Clause because they were imposed as user fees to reimburse Pennsylvania for the costs of highway maintenance. The Court stated that “Pennsylvania’s flat taxes . . . discriminate against out-of-state vehicles by subjecting them to a much higher charge per mile traveled in the State, and they do not even purport to approximate fairly the cost or value of the use of Pennsylvania’s roads.” Id., at 290 . The reasoning of American Trucking Assns. cannot be extended outside the context of the Commerce Clause. The Court there was faced with particular constitutional restrictions on fees and taxes not present in this case, that a fee charged by a State not discriminate against out-of-state vehicles and not place an undue burden on interstate commerce. The flat taxes were objectionable because, even though they were facially neutral, their effect was to subject out-of-state vehicles, which traveled on average much fewer miles inside Pennsylvania than did in-state vehicles, to a much higher charge per mile traveled. The taxes failed what we have described as the “internal. consistency” requirement of the Commerce Clause. Id., at 282-287 ; see also Tyler Pipe Industries, Inc. v. Washington State Department of Revenue, 483 U. S. 232 , 247 (1987). There is no similarly exacting requirement under the Just Compensation Clause. On the contrary, the Just Compensation Clause “has never been read to require the . . . courts to calculate whether a specific individual has suffered burdens ... in excess of the benefits received” in determining whether a “taking” has occurred. Keystone Bituminous Coal Assn. v. DeBenedictis, 480 U. S. 470 , 491, n. 21 (1987).
8 In Webb’s Fabulous Pharmacies, Inc. v. Beckwith, the Court struck down a Florida statute appropriating interest on funds deposited into a court registry by an interpleader complainant. Florida law provided for both the deduction of a small percentage of the interpleader funds as a fee for services rendered by the clerk of the court and the deduction of interest earned on the funds. “It is obvious that the interest was not a fee for services, for any services obligation to the county was paid for and satisfied by the substantial fee charged . . . and described specifically ... as a fee ‘for services’ by the clerk’s office.” 449 U. S., at 162. We failed to discern any justification for the deduction of the interest other than the bare transfer of private property to the county. We expressed “no view as to the constitutionality of a statute that prescribes a county’s retention of interest earned, where the interest would be the only return to the county for services it renders,” id., at 165, a situation more analogous to the case at bar.
9 Sperry argues, however, that we should not even consider the amount deducted by the Federal Reserve Bank of New York because the deduction was akin to a “permanent physical occupation” of its property and therefore was a •per se taking requiring just compensation, regardless of the extent of the occupation or its economic impact. See Loretto v. Teleprompter Manhattan CATV Corp., 458 U. S. 419 , 441 (1982). The Court of Appeals agreed with Sperry. 853 F. 2d 904 , 906-907 (CA Fed. 1988). It is artificial to view deductions of a percentage of a monetary award as physical appropriations of property. Unlike real or personal property, money is fungible. No special constitutional importance attaches to the fact that the Government deducted its charge directly from the award rather than requiring Sperry to pay it separately. If the deduction in this case were a physical occupation requiring just compensation, so would be any fee for services, including a filing fee that must be paid in advance. Such a rule would be an extravagant extension of Loretto.
It is not at all dispositive that the award to Sperry was more the result of private negotiations between Sperry and Iran than the Tribunal procedures placed at Sperry’s disposal. Sperry filed its claim with the Tribunal and had a formal award entered. Furthermore, Sperry may be required to pay a charge for the availability of the Tribunal even if it never actually used the Tribunal; Sperry received the “benefit from [the Tribunal] in the sense that the services are available for [its] use.” Massachusetts v. United States, supra,
1 — I I — f
We turn next to Sperry’s due process claims. Sperry urges that § 502 violates the Due Process Clause because the deductions apply to awards, such as Sperry’s, made by the Tribunal prior to the enactment of the statute. Our standard of review is settled:
“[Retroactive legislation does have to meet a burden not faced by legislation that has only future effects. Tt does not follow . . . that what Congress can legislate prospectively it can legislate retrospectively. The retroactive aspects of legislation, as well as the prospective aspects, must meet the test of due process, and the justifications for the latter may not suffice for the former.’ But that burden is met simply by showing that the retroactive application of the legislation is itself justified by a rational legislative purpose.” Pension Benefit Guaranty Corporation v. R. A. Gray & Co., 467 U. S. 717 , 730 (1984) (quoting Usery v. Turner Elkhorn Mining Co., 428 U. S. 1 , 16-17 (1976)) (citation omitted).
We agree with the United States that the retroactive application of § 502 is justified by a rational legislative purpose. Retroactive application of §502 ensures that all successful claimants before the Tribunal are treated alike in that all have to contribute toward the costs of the Tribunal. If Congress had made the application of § 502 prospective only, the costs of the Tribunal would have fallen disproportionately on the claimants whose awards, for whatever reason, were
Nor does §502 violate the equal protection component of the Due Process Clause[10] because it assesses a user fee only against claimants who have actually received an award from the Tribunal and not against all claimants before the Tribunal. The classification implicitly made by § 502 neither burdens fundamental constitutional rights nor creates suspect classifications, so again our standard of review is that of rationality. See United States Railroad Retirement Board v. Fritz, 449 U. S. 166 , 174-175 (1980). Congress could have rationally concluded that only those who are successful before the Tribunal realize a benefit therefrom sufficient to justify assessment of a fee. Congress could also have determined that assessing a user fee against all claimants would undesirably deter those whose claims were small or uncertain of success from presenting them to the Tribunal. This case is wholly unlike Rinaldi v. Yeager, 384 U. S. 305 (1966), where the Court was unable to discern any legitimate interest that was served by a requirement that the State be reimbursed for the cost of criminal trial transcripts by incarcerated prisoners unsuccessful in their appeals but not by other indigent appellants, even other unsuccessful ones who had not been incarcerated. Here the costs are imposed on only the successful claimants, not, as in Rinaldi, only the unsuccessful ones, a situation presenting entirely different considerations.
10 See Bolling v. Sharpe, 347 U. S. 497 , 499 (1954).
f — H <
As a final ground for affirming the judgment below, Sperry relies on an argument presented to, but not passed on by, the Court of Appeals, i. e., that § 502 was enacted in violation of the Origination Clause of Article I, § 7, which provides that “[a]ll Bills for raising Revenue shall originate in the House of Representatives; but the Senate may propose or concur with Amendments as on other Bills.” Sperry refers us to the legislative history of the Foreign Relations Authorization Act, which indicates that § 502 was added as a Senate amendment to a bill that contained no revenue-raising provisions when it originated in the House.
We do not reach the merits of this contention. In another case to be argued this Term, we have directed the parties to brief whether claims based on the Origination Clause present nonjusticiable political questions. See United States v. Munoz-Flores, cert. granted, post, p. 808; cf. INS v. Chadha, 462 U. S. 919 , 940-943 (1983); Baker v. Carr, 369 U. S. 186 , 217 (1962). Although this Court has on prior occasions appeared to address the merits of Origination Clause claims, see, e. g., Flint v. Stone Tracy Co., 220 U. S. 107 , 143 (1911); Millard v. Roberts, 202 U. S. 429 (1906); Twin City Bank v. Nebeker, 167 U. S. 196 (1897), it would be inappropriate for us to do so now, before we decide the threshold question of justiciability in Munoz-Flores. Furthermore, even assuming that Origination Clause claims are justiciable, we would benefit from the views of the Court of Appeals, which found it unnecessary to address the Origination Clause issue. Accordingly, the judgment of the Court of Appeals is reversed, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
