OPINION
Appellants Willem and Marsha Onink appeal the district court’s application of the federal interest rate as defined by 28 U.S.C. § 1961(a) to an award of post-petition interest pursuant to 11 U.S.C. § 726(a)(5). This appeal presents the narrow but important issue of whether such post-petition interest is to be calculated using the federal judgment interest rate or is determined by the parties’ contract or state law. We conclude that 11 U.S.C. § 726(a)(5) mandates application of the federal interest rate. Accordingly, we AFFIRM.
Appellee Samuel Duke Cardelucci owns and operates several rubbish companies in Southern California. On January 15, 1993, a California state court jury found that Cardelucci had engaged in predatory pricing and was jointly and severally liable to the Oninks for unfair trade practices. The state court subsequently entered judgment in the amount of $5,423,825.50 plus interest calculated at the rate of 10% per annum in favor of the Oninks. The state court judgment was ultimately affirmed on appeal with the amount of damages modified to $5,273,147.50 plus interest at the applicable legal rate.
After judgment was entered in the state court action, Cardelucci filed a voluntary petition for relief under Chapter 11 in the United States Bankruptcy Court for the Central District of California. Cardeluc-ci’s Modification of Fourth Amended Plan of Reorganization provided for payment in full of the Oninks’ claim with post-confirmation interest at the rate of 5% and post-petition interest at a rate to be determined under the provisions of the Bankruptcy Code. During subsequent proceedings before the bankruptcy court regarding the Plan, the parties agreed that the Oninks were entitled to post-petition interest but disputed whether the applicable interest rate was California’s state statutory interest rate of 10% or the federal interest rate. The bankruptcy court held that the federal interest rate of approximately 3.5%, calculated pursuant to 28 U.S.C. § 1961(a), rather than the judgment rate provided for by state law, applied. Thereafter, the On-inks withdrew their objections to the Plan without prejudice to their right to appeal the interest rate determination and the bankruptcy court ordered the Plan confirmed. The Oninks appealed the bankruptcy court’s determination to the district court which affirmed the bankruptcy court’s ruling. This appeal followed.
This Court reviews de novo the district court’s decision on an appeal from a bankruptcy court.
In re Gruntz,
*1234 Where a debtor in bankruptcy is solvent, an unsecured creditor is entitled to “payment of interest at the legal rate from the date of the filing of the petition” prior to any distribution of remaining assets to the debtor. 11 U.S.C. § 726(a)(5). The question presented by this appeal is whether “interest at the legal rate” means a rate fixed by federal statute or a rate determined either by the parties’ contract or state law. The Bankruptcy Code does not define the term “interest at the legal rate” and there is a paucity of legislative history regarding this statutory provision.
Although no Court of Appeals has addressed this issue, bankruptcy courts have split over the correct interpretation of this phrase, finding that it either means one single rate as determined by 28 U.S.C. § 1961(a)(the “federal judgment rate approach”) or is based on a contract rate or applicable state law (the “state law approach”).

In re Beguelin,
The principles of statutory interpretation lend strong support to the conclusion that Congress intended “interest at the legal rate” in 11 U.S.C. § 726(a)(5) to mean interest at the federal statutory rate pursuant to 28 U.S.C. § 1961(a). Congress specifically chose the language “interest at the legal rate,” replacing the originally proposed language “interest on claims allowed.”

Ebben v. Comm’r,
The definite article “the” instead of the indefinite “a” or “an” indicates that Congress meant for a single source to be used to calculate post-petition interest.
See, e.g., American Bus Ass’n v. Slater,
Additionally, using the federal rate promotes uniformity within federal law. Upon the filing of the bankruptcy petition, creditors with a claim against the estate must pursue their rights to the claim in federal court and entitlement to a claim is a matter of federal law.
See Bursch v. Beardsley & Piper,
It has long been the rule that an award of post-judgment interest is procedural in nature and thereby dictated by federal law.
Hanna v. Plumer,
Lastly, applying a single, easily determined interest rate to all claims for post-petition interest ensures equitable treatment of creditors. An overriding policy consideration in an award of interest to a creditor is the balancing of equities among the creditors.
See Vanston Bondholders Protective Committee v. Green,
In addition to promoting fairness among creditors, application of the federal rate is the most judicially efficient and practical manner of allocating remaining assets. Calculating the appropriate rate and amount of interest to be paid to a myriad of investors has the potential to overwhelm what could otherwise be a relatively simple process pursuant to 11 U.S.C. § 726(a)(5).
See Beguelin,
The Court recognizes that these two interests, fairness among creditors and administrative efficiency, may be of limited relevance in certain bankruptcy proceedings. Where there are only a few unsecured creditors seeking post-petition interest and there are sufficient assets to pay all claims for all interest, there will be no concerns regarding equity among creditors or practicality. In those instances, a debt- or may receive a windfall from the application of a lower federal interest rate to an award of post-petition interest. Nonetheless “interest at the legal rate” is a statutory term with a definitive meaning that cannot shift depending on the interests invoked by the specific factual circumstances before the court.
See In re Thompson,
Appellants make a final argument that under the circumstances of this case, an award of interest pursuant to a federal statute violates substantive due process. Assuming,
arguendo,
that there is a substantive right to post-petition interest, Appellants’ substantive due process claim fails because the application of the federal interest rate to all claims is rationally related to the legitimate interests in efficiency, fairness, predictability, and uniformity within the bankruptcy system. While the instant case might lend itself to easy application of an alternate interest rate, “a classification does not fail rational-basis review because it ‘is not made with mathematical nicety or because in practice it results in some inequality.’ ”
Heller v. Doe,
AFFIRMED.
