n the 1980’s and early 1990’s, petitioner Paul Glover was the Vice President and General Counsel of the Chicago Truck Drivers, Helpers, and Warehouse Workers Union (Independent). The evidence showed Glover used his control over the union’s investments to enrich himself and his co-conspirators through kickbacks. When the malfeasance was discovered, he was tried in the United States District Court for the Northern District of Illinois. His first trial ended when the jury could not agree, but a second jury convicted him. The presentence investigation report prepared by the probation office recommended that the convictions for labor racketeering, money laundering, and tax evasion be grouped together under United States Sentencing Commission, Guidelines Manual §3D1.2 (Nov. 1994), which allows the grouping of “counts involving substantially the same harm.” The Government, insisting that the money laundering counts could not be grouped with the other counts, objected to that recommendation, and the District Court held a hearing on the matter. The money laundering counts, it ruled, should not be grouped with Glover’s other offenses. The ruling, as the trial court viewed it, was in conformance with decisions in those Courts of Appeals which had refused to group money laundering counts with other counts for various reasons.
On appeal to the Seventh Circuit, Glover’s counsel (the same attorneys who represented him in District Court) did not raise the grouping issue; instead, they concentrated on claims that certain testimony from his first trial should not have been admitted at his second trial and that he should not have been assessed a two-level increase for perjury at his first trial. A short time after argument on Glover’s appeal, a different panel of the Seventh Circuit held that, under some circumstances, grouping of money laundering offenses with other counts was proper under § 3D1.2. United States v. Wilson, 98 F. 3d 281 (1996). A month and a half later, the Seventh Circuit rejected both of Glover’s arguments and affirmed his conviction and sentence. 101 F. 3d 1183 (1996).
Glover filed a pro se motion to correct his sentence under 28 U. S. C. §2255 (1994 ed., Supp. III). The failure of his counsel to press the grouping issue, he argued, was ineffective assistance, a position confirmed, in his view, by the Court of Appeals’ decision in Wilson. The performance of counsel, he contended, fell below a reasonable standard both at sentencing, when his attorneys did not with any clarity or force contest the Government’s argument, and on appeal, when they did not present the issue in their briefs or call the Wilson decision to the panel’s attention following the oral

The District Court denied Glover’s motion, determining that under Seventh Circuit precedent an increase of 6 to 21 months in a defendant’s sentence was not significant enough to amount to prejudice for purposes of Strickland v. Washington, supra. As a result, the District Court did not decide the issue whether the performance of Glover’s counsel fell below a reasonable standard of competence. On appeal to the Seventh Circuit, the Government argued only that Glover had not suffered prejudice within the meaning of Strickland. See App. to Reply Brief for Petitioner 1a-22a. Citing Durrive v. United States, 4 F. 3d 548 (CA7 1993), the Government contended that even were the performance of Glover’s counsel ineffective, the resulting additional 6 to 21 months, under the law as established in the Seventh Circuit, would not constitute prejudice. App. to Reply Brief for Petitioner 21a. The Court of Appeals affirmed, relying on that theory. 182 F. 3d 921 (1999) (table). We granted Glover’s petition for certiorari. 530 U. S. 1261 (2000).
The Government no longer puts forth the proposition that a 6- to 21-month prison term increase is not prejudice under Strickland. It now acknowledges that such a rule, without more, would be “inconsistent with this Court’s cases and unworkable.” Brief for United States 18.
It appears the Seventh Circuit drew the substance of its no-prejudice rule from our opinion in Lockhart v. Fretwell, 506 U. S. 864 (1998). Lockhart holds that in some circumstances a mere difference in outcome will not suffice to establish prejudice. Id., at 369. The Seventh Circuit extracted from this holding the rule at issue here, which denies relief
The Seventh Circuit’s rule is not well considered in any event, because there is no obvious dividing line by which to measure how much longer a sentence must be for the increase to constitute substantial prejudice. Indeed, it is not even clear if the relevant increase is to be measured in absolute terms or by some fraction of the total authorized sentence. See Martin v. United States, 109 F. 3d 1177 , 1183 (CA7 1996) (Rovner, J., dissenting from denial of rehearing en banc). Although the amount by which a defendant’s sentence is increased by a particular decision may be a factor to consider in determining whether counsel’s performance in failing to argue the point constitutes ineffective assistance, under a determinate system of constrained discretion such as the Sentencing Guidelines it cannot serve as a bar to a showing of prejudice. Compare Spriggs v. Collins, 993 F. 2d 85 , 88 (CA5 1993) (requiring a showing that a sentence would have been “significantly less harsh” under the Texas discretionary sentencing scheme), with United States v. Phillips, 210 F. 3d 345 (CA5 2000) (finding prejudice under the Sentencing Guidelines when an error by counsel led to an increased sentence). We hold that the Seventh Circuit erred in engrafting this additional requirement onto the prejudice branch of the Strickland test. This is not a case where trial strategies, in retrospect, might be criticized for leading to a harsher sentence. Here we consider the sentencing calculation itself, a calculation resulting from a ruling which, if it had been error, would have been correctable on appeal. We express no opinion on the ultimate merits of Glover’s claim because the question of deficient performance is not before us, but it is clear that prejudice flowed from the asserted error in sentencing.
III
The judgment of the Seventh Circuit is reversed. The case is remanded for further proceedings consistent with this opinion.
It is so ordered.
