OPINION
I. INTRODUCTION
This appeal is brought by plaintiffs who settled a class action suit for private nuisance against a Sitka pulp mill. Plaintiffs sought $1 million in attorney’s fees under the common fund doctrine. The trial court declined to apply the common fund doctrine, apparently concerned that it conflicts with Alaska Civil Rule 82. Applying Rule 82, the court awarded only $500,000 to plaintiffs’ counsel, and plaintiffs appeal that award. We reverse the judgment of the superior cоurt and remand the case for determination of a reasonable attorney’s fee award under the common fund doctrine.
II. FACTS AND PROCEEDINGS
In February 1992, Larry Edwards, representing a class of shoreline property owners, sued the Alaska Pulp Corporation (APC) and its parent company for nuisance. Edwards complained about discharges into air and water from the defendants’ Sitka pulp mill.
The plaintiff class was represented by an attorney from Sitka, as wеll as law firms from Soldotna; Burlington, Vermont; and Washington, D.C. The plaintiffs retained their counsel under a 33⅞% contingency fee arrangement.
The parties litigated the case vigorously for several years before it settled. The parties contested a number of pretrial matters, including the addition of APC’s parent corporation as a defendant, class certification and an unsuccessful motion for decertification, a successful motion fоr change of venue from Juneau to Sitka, an initially unsuccessful motion for change of venue out of Sitka, and a change of venue from Sitka to Juneau based on responses to the jury questionnaire in Sitka. The parties engaged in pretrial discovery involving over 100,000 pages of documents, eighty depositions, and several disputes over the adequacy and confidentiality of responses. The defendants made several motions for summary judgment, all of which were denied completely or in part. The plaintiffs successfully challenged the constitutionality of a new statute that would have retroactively barred the suit.
APC closed its pulp mill on September 30, 1993. In September 1994, before trial began in Juneau, the parties reached a settlement agreement. The agreement required APC to establish a Sitka Alaska Permanent Charitable Trust (the Trust) to support educational and charitablе activities in Sitka. APC was to provide $3 million to fund the Trust, making an initial payment of $2 million followed by five annual installments of $200,000. The agreement stated that “[i]n no event shall any member of the class be entitled to receive any payment from the Settlement.”
The settlement agreement allowed the plaintiffs’ counsel to apply to the court for attorney’s fees and costs “in accordance with Alaska Rules [sic] of Civil Procedure 23,” and provided thаt any fees and costs awarded to plaintiffs’ counsel would be paid out of the Trust, to a maximum of $270,000 in costs and $1 million in fees. The agreement further limited funding for attorney’s fees and costs to no more than half of the initial endowment and subsequent net income of the Trust.
Following the settlement, the plaintiffs’ attorneys applied to the superior court for $1 million of fees under the common fund doctrine. In response, the defendants urged that under Alaska Civil Rule 82, counsel for the plaintiffs should receive either nothing, because they were not the prevailing party, *754 or $84,500. 1
Counsel for the plaintiffs calculated the value of their legal work at over $1.7 million; plaintiffs’ counsel also incurred $285,000 in costs. By comparison, the defendants incurred legal fees of $3.4 million, in addition to $1.07 million in costs. The superior court found that both the hourly rate and the time spent on the ease by plaintiffs’ counsel were reasonablе, in light of the complexity of the case and the quality of their work. The court noted that “[t]he number of lawyers plaintiffs used” limited costs, as' did “[t]he plaintiffsF] refusal to depose numerous witnesses.” The court implicitly held that Rule 82 and not the common fund doctrine applied to the award of attorney’s fees in the case:
The court finds that a federal court applying the common fund benefit doctrine or the lodestar method and Federal Rule of Civil Procedure 23(b), might well award attorney’s fees to Counsel in at least the amount Counsel are requesting. It would be inequitable not to award attorney’s fees, where a Trust Fund is generated for the benefit of an identifiable community.
However, the common fund benefit doctrine is more liberal in granting prevailing party status than Alaska Civil Rule 82. Hickel v. Southeast Conference, 868 P.2d [919] at 925 [(Alaska 1994) ] (“Unlike Alaska’s approach, the federal approach is extremely generous in granting prevailing party status.”).
Finding that the plaintiffs were the prevailing parties and that under Rule 82(b)(3) the length and complexity of the litigation justified a departure from' the scheduled amount of $84,500, the court relied upon Rule 82 in awarding $500,000 in attorney’s fees, as well as $270,000 in costs, to the plaintiffs’ counsel.
Counsel for the plaintiffs appeal the fee award. They claim that Rule 23, not Rule 82, governs attorney’s fees in this case and that the superior court should have applied the cоmmon fund doctrine to provide full reasonable attorney’s fees. Under the common fund doctrine, they claim, the court should have employed the lodestar method of calculating fees, which entitles them to $1 million, the amount of the settlement cap on attorney’s fees.
III. DISCUSSION
A. The Common Fund Doctrine Applies in Alaska.
The first question before us is whether the common fund doctrine is part of Alaska law.
2
That doctrine holds that “a litigant or a lawyer who recovers a common fund for the benefit of persons other than himself or his client is entitled to a reasonable attorney’s fee from the fund as a whole.”
Boeing Co. v. Van Gemert,
One rationale underlying the doctrine is the prevention of unjust enrichment. As explained by the United States Supreme Court, “persons who obtain the benefit of a lawsuit without contributing to its cost are unjustly enriched at the successful litigant’s expense.”
Boeing,
We applied the restitutionary principle of the common fund doctrine when we required an insurer to bear a proportionate share of the attorney’s fees for recovery of a workеrs’ compensation disbursement.
Cooper v. Argonaut Ins. Cos.,
APC’s principal argument against applying the common fund doctrine in Alaska is that the doctrine conflicts with Rule 82. Consideration of this contention requires a comparison of Rule 82 and alternative doctrines governing attorney’s fees.
Under the “American rule,” each party pays its attorney’s fees, regardless of who prevails.
See Alyeska Pipeline,
The common fund doctrine differs from exceptions to the American rule in that the doctrine is a mechanism for
fee-spreading,
not
fee-shifting;
the common fund doctrine requires reimbursement of fees “by the
prevailing
party, not the losing party.”
Bowles,
Alaska is the only state that does not follow the American rule. Alaska Judicial Council,
Alaska’s English Rule: Attorney’s Fee Shifting in Civil Cases
1 (1995). The purpose of this state’s fee-shifting provision, Civil Rule 82, is “to partially compensate a prevailing party for the expenses incurred in winning his case.”
Tobeluk v. Lind,
APC’s claim that Rule 82 preempts the common fund doctrine misunderstands the separate purposes served by the two rules. While the common fund doctrine is a fee-spreading mechanism which prevents unjust enrichment of those who derive benefit from the efforts of others, Rule 82 is a fee-shifting tool which provides partial reimbursement of a prevailing party’s legal fees.
Rule 82 was not intended to cap recovery of attorney’s fees under other doctrines. Despite the existence of Rule 82, Alaska has set attorney’s fee awards under other exceptions to the American rule.
Singh,
B. The Common Fund Doctrine Applies in this Case.
The parties dispute whether the settlement reached for the community in this case qualifies as a “common fund.” We conclude, as a matter of law, that the common fund doctrine is applicable to the case at hand. 7
The primary reasons for applying the common fund doctrine to this case are to prevent unjust enrichment and provide reasonable compensation to class counsel. In this case, the plaintiffs’ lawyers created a fund that would not otherwise exist. The fund contains a specified amount, and it benefits a limited community. 8 The benefit to the community is measurable when expenditures from the Trust are made for community activities. Thus the doctrine allows fees tо be spread among those benefited by the suit in proportion to the benefits they received. See John P. Dawson, Lawyers and Involuntary Clients in Public Interest Litigation, 88 Harv.L.Rev. 849, 916-22 (1975). Without application of the doctrine in this case, the fund’s beneficiaries would receive a clear benefit from the efforts of the plaintiffs’ attorneys whose work created the fund, while those attorneys would not be sufficiently compensated. We conclude that the facts in this case give rise to the unjust enrichment or free rider concerns that the common fund doctrine is intended to address, and that application of the doctrine to this ease is appropriate. 9
C. Determination of a Reasonable Fee under the Common Fund Doctrine.
Although courts may differ and the federal circuits are divided over how best to determine the amount of attorney’s fees under the common fund doctrine, all agree that a “reasоnable” attorney’s fee is the proper standard.
Calculation of a reasonable fee under the common fund doctrine is an issue of first impression in Alaska. While we have considered various approaches to determining a proper fee award, these have arisen in the context of statutory schemes such as 42 U.S.C. § 1988. 10
*757
Courts have adopted three distinct approaches to arriving at the calculation of a reаsonable fee. The first, adopted in early Supreme Court common fund cases, is to award attorneys a percentage of the fund.
Pettus,
Under the “lodestar” approach, the court determines the number of hours an attorney rеasonably spent on the case and multiplies that number by a reasonable hourly rate to determine an initial attorney’s fee figure, which can then be adjusted for circumstances.
Lindy Bros. Bldrs., Inc. v. American Radiator & Standard Sanitary Corp.,
Under a third approach, the Fifth Circuit identified twelve factors for courts to consider and weigh.
Johnson v. Georgia Highway Express, Inc.,
From these three alternative approaches federal courts have developed a number of hybrid or “blended” approaches. The prevalent blended approach is the modified lodestar or lodestar/multiplier. In re Wash. Pub. Power Supply Sys. Sec. Litig., 19 F,3d 1291, 1294-95 & n. 2 (9th Cir.1994). Under this approach, the trial court determines the lodestar amount based on a reasonable hourly rate and the number of hours. The court then has discretion to determine a multiplier which is applied to the lodestar amount to establish the final attorney’s fee figure. Factors to be considered in determining whether to use a multiplier include the Johnson-Kerr factors, the risk to counsel in taking the case, achievement of extraordinary results, the quality of representation, and substantial delay in payment. Id. at 1301-05. 11
The federal circuits differ over this issue. The First, Sixth, Seventh and Ninth Circuits accept either the percentage or modified lodestar approach and leave the choice to trial judges’ sound discretion.
In re Thirteen Appeals Arising Out of the San Juan Dupont Plaza Hotel Fire Litig.,
In
Washington Public Power,
the Ninth Circuit upheld a trial court’s decision to award $32 million in attorney’s fees under a modified lodestar analysis to lawyers who recovered $687 million in settlements.
[I]n common fund cases, no presumption in favor of either the percentage or the lodestar method encumbers the district court’s discretion to choose one or the other. As always, when determining attorneys’ fees, the district court should be guided by the fundamental principle that fee awards out of common funds should be ‘reasonable under the circumstances.’
Id.
at 1296 (quoting
Florida v. Dunne,
We agree with the logic that the Ninth Circuit followed in Washington Public Power. Situations may exist where application of the lodestar or the percentage method will render an unfair result. For example, in a case in which an attorney recovers a small fund, application of the lodestar might cause attorney’s fees to devour most or all of the fund, while in a case in which an attorney quickly negotiatеs an enormous settlement, the percentage method might cause an inordinate windfall. 13 Giving trial courts the flexibility to decide between percentage and lodestar allows the fairest determination of reasonable attorney’s fees in each situation. We therefore hold that a trial court applying the common fund doctrine has the discretion to determine whether to apply the percentage of the fund method or thе modified lodestar method in order to calculate attorney’s fees.
Trial courts that choose to apply the percentage of the fund method frequently adopt 25% as a baseline percentage and then modify it according to circumstances.
14
We think this is a sound approach for trial judges who choose to use the percentage approach. One frequently-mentioned consideration is that the percentage may decrease as the size of the fund increases. In addition to the size of the fund, other considerations that may affect the percentage include the
Johnsorir-Kerr
factors, the time required to reach a settlement, whether class members have substantial objections to the settlement terms or the fee request, non-monetary benefits conferred by the settlement, the economies of scale involved in a class action, and the structure of the settlement.
Camden I,
*759
Mindful that a trial court is acting as a court of equity in common fund cases, in determining a reasonable fee the court should exercise its discretion to avoid unjust enrichment of either counsel or beneficiaries. As Justice Frankfurter wrote about determining attorney’s fees from a common fund, “[a]s in much else that pertains to equitable jurisdiction, individualization in the exercise of a discretionary power will alоne retain equity as a living system and save it from sterility.”
Sprague,
On remand, the superior court could apply either a lodestar analysis or a percentage of the fund analysis, whichever it deems mоre appropriate.
IV. CONCLUSION
The superior court found that Civil Rule 82 and not the common fund doctrine governed attorney’s fees in this case. We hold that it erred. Therefore we REVERSE the judgment of the superior court and REMAND for determination of attorney’s fees under the common fund doctrine.
Notes
. The Rule 82(b)(1) schedule sets the amount of. reimbursable fees in this case at $84,500, based on the $3 million amount of the settlement and the fact that the case was contеsted but not tried.
. We review such legal questions
de novo. Moore v. State Dep't ofTransp.,
. The doctrine is sometimes stated slightly more broadly to include costs other than attorney's fees.
See City and County of San Francisco v. Sweet,
.The doctrine was further developed in
Sprague v. Ticonic Nat’l Bank,
. Although the doctrine initially developed in federal courts, nothing limits it to federal law. Most statеs apply the doctrine.
See,
e.g.,
Sweet,
. Although this case involves a settlement, in a case resolved by trial, a successful litigant could recover a fund from which fees would be paid under the common fund doctrine and still apply after trial for an attorney’s fee award under Rule 82 from the non-prevailing party. In such a case, Rule 82 would appropriately allow partial reimbursement for charges against the fund.
. Because this appeal involves an application for attorney’s fees from a fixed settlement fund, the parties may no longer be adversaries with respect to the issues in this case.
See In re Continental Ill. Sec. Litig.,
. The number of beneficiaries here is comparable to or smaller than that of beneficiaries in other common fund cases, such as derivative securities or toxic tort litigation.
See, e.g., In re “Agent Orange’’ Prod. Liab. Litig.,
. Not every case in which a party or a party’s counsel produces a benefit for others implicates the common fund doctrine. To determine whether the doctrine is applicable to a fact pattern, the Ninth Circuit employs a set of criteria that the U.S. Supreme Court applied in
Boeing
and
Alyeska Pipeline.
According to these criteria, "[t]he common fund doctrine is properly applied ... if ‘(1) the class of beneficiaries is sufficiently identifiable, (2) the bеnefits can be accurately traced, and (3) the fee can be shifted with some exactitude to those benefitting.’ ”
Paul, Johnson, Alston & Hunt v. Graulty,
.See, e.g., Singh,
. The court in
Washington Public Power
declined to extend to common fund cases the rationale of
City of Burlington v. Dague,
. The Fifth Circuit requires the lodestar method, while the D.C. and Eleventh Circuits require the percentage method.
In re Thirteen Appeals,
.
See Rawlings v. Prudential-Bache Properties, Inc.,
. While acceptable percentage awards have ranged from under 10% to 50%, the consensus seems to be that 20% to 30% (or 19% to 33%) is normally reasonable.

Monique Lapointe,
Attorney’s Fees in Common Fund Actions,

Procedural Solutions to the Attorney's Fee Problem in Complex Litigation,
26 U.Rich.L.Rev. 41, 47^18 & n. 37 (1991). The median and the most common figure seems to be 25% of the fund.
In re Pacific Enters. Sec. Litig.,
.Trial courts which elect to follow a percentage approach must exercise their independent discretion in arriving at a fair and reasonable fee award under the common fund doctrine. The percentage figures in lawyers’ contingent fee agreements with the class representatives “are not controlling on the court's determination of fees for the class recovery.” Alba Conte,
Attorney Fee Awards
61 (2d ed. 1993). However, at least one appellate сourt thought the contingency fee level worth consideration.
