delivered the opinion of the Court.
In this appeal from an oil and gas billing dispute, we determine the accrual date for postjudgment interest when a remand for further proceedings requires new evidence. To resolve this question, we assess the Texas Finance Code, our rules of procedure, and our precedent. The Finance Code provides that postjudgment interest accrues from a money judgment’s date. But importantly, remanded cases such as
Here, the court of appeals remanded the case to the trial court so that it could assess the prejudgment interest based upon when the defendant received certain billings from the plaintiff. The trial court determined that such evidence was not in the record and that the record had to be reopened. Rather than obtain the additional evidence, the claimant instead waived its claim for prejudgment interest. The trial court then awarded post-judgment interest from the date of its original, erroneous judgment, and the court of appeals affirmed. We find no abuse of discretion in the trial court’s determination that new evidence was needed. But because the remand necessitated reopening the record for additional evidence, the Finance Code and our rules of proee-dure require that postjudgment interest accrue from the final judgment date rather than the original, erroneous judgment. Accordingly, we reverse the court of appeals’ judgment and remand for the trial court to enter judgment in accordance with this opinion.
I. Background
Castle Texas Production Limited Partnership (Castle) operates gas wells in which the Lawrence Allan Long Trust, the Charles Edward Long Trust, the Larry Thomas Long Trust, and the John Stephen Long Trust (collectively “the Long Trusts”
On remand, Castle made various motions beginning in March 2005, arguing that no new evidence was required for the trial court to recalculate prejudgment interest. When the trial court disagreed
II. Discussion
This appeal requires us to determine the date from which postjudgment interest begins to accrue when a remand requires further evidentiary proceedings. Prejudgment interest and postjudgment interest both compensate a judgment creditor for her lost use of the money due her as damages. Phillips v. Bramlett,
A claimant would prefer postjudgment interest to accrue from the date of the original, erroneous judgment for several reasons. First, postjudgment interest accrues on prejudgment interest
A. The Final Judgment Rule
To determine when post-judgment interest begins to accrue, we must interpret relevant statutes and our rules of procedure, which are issues we review de novo. Morris v. Aguilar,
We assess a judgment’s finality differently, depending upon the context. For example, the finality test for the purpose of appeal differs from the finality test for when a court’s power to alter a judgment ends or when the judgment becomes final for the purpose of claim and issue preclusion. Street v. Honorable Second Court of Appeals,
B. The “Can or Does Render” Exception
Texas Rule of Appellate Procedure 43.3 establishes a limited exception to the general rule that postjudgment interest accrues from the final judgment date. Rule 43.3 provides that, “[w]hen reversing a trial court’s judgment, the court must render the judgment that the trial court should have rendered, except when (a) a remand is necessary for further proceedings; or (b) the interests of justice require a remand for another trial.” Tex. R.App. P. 43.3. Though our precedents on postjudgment interest have involved this exception rather than the general post-judgment-interest accrual rule, such precedents nonetheless offer guidance about the rule’s purpose and contours.
We first interpreted the predecessor to Rule of Appellate Procedure 43.3 more than a half century ago. In D.C. Hall Transport, Inc. v. Hard, the jury rendered a verdict for the plaintiff, but the trial court granted the defendants’ motion for judgment notwithstanding the verdict.
We likewise applied the American Paper exception in Thornal v. Cargill, Inc.,
Most recently, in Bramlett, we summarized American Paper and Thomal as holding that “when an appellate court reverses a trial court’s judgment and renders judgment on appeal, postjudgment interest begins to run from the date of the trial court’s judgment, not the later date of the appellate court’s judgment.”
Thus, the general rule is that post-judgment interest accrues from the date of the judgment, which is the final judgment in a case where the trial court issues multiple judgments. Tex. Fin.Code § 304.005(a); Tex.R. Civ. P. 301. The exception is when the appellate court renders (or could have rendered) judgment, in which case postjudgment interest accrues from the date of trial court’s original, erroneous judgment. Tex.R.App. P. 43.3. But when an appeal instead results in a retrial or a remand for further proceedings where new evidence is required, postjudgment interest will accrue from the trial court’s subsequent judgment.
The purpose behind the long-standing exception under Rule of Appellate Procedure 43.3 confirms the general rule that postjudgment interest should accrue from
We cannot agree with Castle that postjudgment interest should always accrue from the date of the trial court’s first judgment. Such an interpretation renders meaningless the Finance Code provisions and Rule of Civil Procedure 301, which require postjudgment interest to accrue from the final judgment date. Similarly, if postjudgment interest always accrues from the date of the original, erroneous trial court judgment, our precedents construing the rules of appellate procedure would have had no need to address whether the appellate court could or did render the judgment the trial court should have rendered. We must interpret statutes and rules of procedure to give them effect, and thus we decline to adopt Castle’s blanket rule that postjudgment interest accrues from the date of the original, erroneous trial court judgment in every proceeding. See City of Waco v. Lopez,
Having determined the parameters of the postjudgment-interest accrual rule and its exception, the parties here raise two related procedural questions: (1) which court decides whether the record must be reopened on remand, and (2) at what point should that decision be based? As a practical matter, the trial court should determine whether the record must be reopened on remand. While Rule of Appellate Procedure 43.3 requires a court of appeals to render the judgment the trial court should have rendered, the limited nature of appellate records can make this task impossible. Such was the case in Bramlett where we remanded for the trial court to enter judgment consistent with our opinion, and the trial court did not reopen the record in order to enter judgment.
Taken together, the Finance Code, our rules of procedure, and our precedent from D.C. Hall to Bramlett require the conclusion that postjudgment interest accrues from the date of the final judgment (rather than the original, erroneous judgment) unless the appellate court can or does render the judgment the trial court should have rendered. As the parties discussed at oral argument, however, our precedent and rules of procedure offer some methods through which courts and parties may affect postjudgment interest with severance, offers of proof, and bills of exception.
Under Texas Rule of Civil Procedure 41, a court may sever and proceed separately with a claim against a party and may sever different grounds of recovery before submission to the trier of fact.
C. The Courts of Appeals
Before the court of appeals’ decision at issue here, only two court of appeals’ opinions had substantively addressed the accrual date for postjudgment interest if the trial court must reopen the record on remand. Both courts of appeals held that postjudgment interest accrues from the date of the original, erroneous trial court judgment. The court of appeals here had previously addressed the issue in State Department of Highways and Public Transportation v. City of Timpson,
Likewise, Timpson relied upon Copper Liquor, as support for the conclusion that postjudgment interest accrues from the date of the original, erroneous trial court judgment.
The other court of appeals to have addressed the question before us was Gamma Group v. Transatlantic Reinsurance Co.,
D. Other Jurisdictions
Other jurisdictions often rely on their particular statutes, rules, and interpreting caselaw, so their relevance here is particularly weak. Nonetheless, we note that California appears to follow this general approach. See Stockton Theatres, Inc. v. Palermo,
Having construed the Finance Code and our rules of procedure to require post-judgment interest to accrue from the final judgment date unless the appellate court can or does render the judgment the trial court should have rendered, we turn to the facts of the case at hand. Castle counterclaimed against the Long Trusts for breach of the parties’ joint operating agreement by failing to pay their share of joint interest billings. The joint operating agreement provided for interest to accrue on joint interest billings not paid within fifteen days of their receipt.
As explained above, postjudgment interest accrues from the final judgment date unless the appellate court can or does render the judgment the trial court should have rendered. And the determination of whether the record must be reopened on remand is one for the trial court in the first instance to be made based upon the time of remand. Here, the trial court determined new evidence was required at the time of remand — a decision the court of appeals did not overturn. In re Castle,
Castle argues that new evidence was not needed because (1) the record included evidence of when the Long Trusts received joint interest billings, and (2) even without such evidence, the trial court had a duty to rule that Castle failed to carry its burden of proving prejudgment interest on the existing record. The Long Trusts argue that, although evidence existed that Castle was entitled to prejudgment interest, the remand required reopening the record for evidence of when the Long Trusts received the billings. We agree with the Long Trusts and hold that the trial court did not abuse its discretion in concluding that it needed additional evidence.
Castle claimed in the trial court that the existing record could substantiate when the Long Trusts received certain joint interest billings because the record included a letter from Castle to the Long Trusts that purportedly enclosed joint interest billings. But the letter Castle filed with the trial court failed to include the allegedly enclosed joint interest billings, and Castle does not argue that any other evidence in the record establishes when the Long Trusts received the billings. Thus, we cannot agree with Castle that the existing
Neither do we agree with Castle that the trial court had a duty to deny it recovery of prejudgment interest on the existing record. Castle relies on Texas Rule of Civil Procedure 270, which provides that a court may permit additional evidence to be offered at any time when it clearly appears necessary to the due administration of justice, except that “in a jury case no evidence on a controversial matter shall be received after the verdict of the jury.” Tex.R. Civ. P. 270. But, Rule 270 is not designed to prohibit the trial court from reopening the record when a court of appeals reverses and remands for further proceedings. The ability to remand a portion of a claim is instead governed by Rule of Appellate Procedure 44. 1, and Castle has not challenged the court of appeals’ decision to remand only the issue of prejudgment interest rather than the entirety of its claim. Tex.R.App. P. 44.1(b). Moreover, the record in 2001 included some evidence that Castle was entitled to prejudgment interest because the Long Trusts had not paid certain amounts owed on joint interest billings by the date of the original judgment. But this was not evidence as to the specific amount of prejudgment interest the Long Trusts owed under the joint operating agreement. Because evidence existed that the Long Trusts owed prejudgment interest, the court of appeals remanded for a recalculation. See Glover v. Tex. Gen. Indem. Co.,
Neither waiver nor severance affect our conclusion. After the trial court required additional evidence on Castle’s prejudgment interest claim, Castle waived the claim. But this waiver of prejudgment interest does not affect the date on which postjudgment interest accrues. Because the trial court did not possess a sufficient record on which to render a correct judgment on its claims in 2001, Castle is not entitled to postjudgment interest from the 2001 judgment. In 2009, Castle amended its pleadings to, for the first time, yield a sufficient record for the trial court to render a correct judgment. Castle is therefore entitled to postjudgment interest from the 2009 judgment.
Finally, the issue of severance does not affect our analysis. The court of appeals did not sever the portion of Castle’s claim it affirmed from the portion it remanded— as we did in Danziger. The court of appeals was familiar with severance, a procedure it implemented in severing the Long Trusts’ claim from Castle’s counterclaim in the first appeal.
III. Conclusion
In sum, under the Finance Code and our rules of procedure, postjudgment interest accrues from the final judgment date unless the appellate court can or does render the judgment the trial court should have rendered. If the trial court determines that it must reopen the record on remand based upon the record and pleadings as they existed at the time of the remand, postjudgment interest will accrue from the subsequent judgment. But if the court of appeals can or does render the judgment the trial court should have rendered, post-judgment interest accrues from the original, erroneous trial court judgment.
Here, the court of appeals remanded for the trial court to assess prejudgment interest based upon the date the Long Trusts received joint interest billings. The trial court determined it required additional evidence to decide that issue. Because there was insufficient evidence in the record establishing when the Long Trusts received the billings and because the trial court had no duty to deny Castle’s request for prejudgment interest on the existing record, we find no basis to conclude that the trial court’s ruling to reopen the record was an abuse of discretion. Accordingly, post-judgment interest must accrue from the trial court’s final judgment in 2009. We reverse the court of appeals’ judgment and remand for the trial court to render judgment for Castle, with postjudgment interest to accrue in accordance with this opinion.
Notes
. Larry T. Long, Sammy Adamson, and Allan Long are the trustees of the Long Trusts and filed suit and pursued this appeal in their official capacities as trustees. For ease of reference, this opinion refers to the trustees in their official capacity as the Long Trusts.
. The court also suggested a remittitur on damages and attorney's fees and, when Castle filed the remittitur, affirmed the trial court’s judgment as modified.
. The trial court subsequently entered a nunc pro tunc final judgment that made no substantive change to the March 2009 final judgment. No party contends the nunc pro tunc judgment has any effect on this proceeding.
. We previously granted review of this appeal and set the matter for oral argument in December 2012. Shortly before oral argument, Castle removed this proceeding to federal court because Castle and its parent corporation had filed for bankruptcy in December 2011. The federal bankruptcy court remanded this proceeding in July 2013, and we again set the matter for oral argument.

. The Finance Code further defines contract interest as "interest that an obligor has paid or agreed to pay to a creditor under a written contract of the parties.” Tex Fin Code § 301.002(a)(1). Much of the present dispute has centered on the prejudgment interest set forth in the joint operating agreement between Castle and the Long Trusts, which is contract interest under the Finance Code.
. As addressed in Part II.B, infra, a trial court may, in appropriate circumstances, sever a rendered claim to make that ruling an appeal-able final judgment that accrues post-judgment interest from the date of severance.

. The court of appeals had addressed various factual determinations that were beyond our jurisdiction, so we could not refuse the writ and adopt that opinion as our own. D.C. Hall,
. Similarly to D.C. Hall, we reversed and remanded a take nothing judgment in Vassallo v. Nederl-Amerik Stoomv Maats Holland and instructed the trial court to enter judgment for the plaintiff.
. We recognize that the cause for a retrial might not be the fault of the claimant, and the record on retrial may be similar to the record from the initial trial. But even in such circumstances, the Finance Code requires interest to accrue from the date of the judgment, which is necessarily the final judgment. Tex. Fin.Code § 304.005(a). And the exception in Rule of Appellate Procedure 43.3 cannot apply to retrials because, under such circumstances, the appellate court cannot render the judgment the trial court should have rendered. See Tex.R.App. P. 43.3. While the Finance Code’s postjudgment interest accrual rule and the exception under our rules of procedure should achieve fairness in most circumstances, fairness is not the test mandated by our statutes and rules to be applied to the calculation of postjudgment interest in a case-by-case fashion. Rather, the parties' awareness of these principles, and the appropriate use of severance, offers of proof, and bills of exception as discussed below, should yield fairness in a predictable context to the greatest extent possible.
. If a party believes the trial court erred in its determination of whether it must reopen the record, such a decision is necessarily reviewable on appeal of the final judgment the trial court enters. Here, Castle disagreed with the trial court’s determination that it must reopen the record. As explained in Part II.E, infra, we hold that the trial court did not abuse its discretion in determining that it needed to reopen the record.
. We have held that a claim is properly severable if: "(1) the controversy involves more than one cause of action, (2) the severed claim is one that would be the proper subject of a lawsuit if independently asserted, and (3) the severed claim is not so interwoven with the remaining action that they involve the same facts and issues.” F.F.P. Operating Partners, L.P. v. Duenez,
. Rule of Civil Procedure 320 provides:
When it appears to the court that a new trial should be granted on a point or points that affect only a part of the matters in controversy and that such part is clearly separable without unfairness to the parties, the court may grant a new trial as to that part only, provided that a separate trial on unliquidated damages alone shall not be ordered if liability issues are contested.
TexR. Civ. P. 320.
.Rule of Appellate Procedure 44.1 provides: If the error affects part of, but not all, the matter in controversy and that part is separable without unfairness to the parties, the judgment must be reversed and a new trial ordered only as to the part affected by the error. The court may not order a separate trial solely on unliquidated damages if liability is contested.
TexJR.App. P. 44.1(b).
. The severed and remanded claim would necessarily have accrued postjudgment interest from the trial court's subsequent judgment date.
. In addition to Danziger, we also severed the disputed issue of attorney's fees from the remainder of a claim on which we rendered judgment in Great American Reserve Insurance Co. v. Britton,
. Parties may also affect postjudgment interest with offers of proof or bills of exception, which allow parties to include in the appellate record matters that do not otherwise appear in the record, such as excluded evidence. Tex.R. Evid. 103(a)(2); Tex.R.App. P. 33.2; Mack Trucks, Inc. v. Tamez,
.Following its decision in Briggs v. Pennsylvania Railroad Co.,
(a) When the Court Affirms. Unless the law provides otherwise, if a money judgment in a civil case is affirmed, whatever interest is allowed by law is payable from the date when the district court’s judgment was entered.
(b) When the Court Reverses. If the court modifies or reverses a judgment with a direction that a money judgment be entered in the district court, the mandate must contain instructions about the allowance of interest.
