PER CURIAM.

Defendants appeal from an order of the circuit court awarding plaintiffs interest based on the entire amount of the jury's award of damages before it was reduced to reflect settlement amounts paid to plaintiffs and from the order of the circuit court ordering defendants to pay costs pursuant to MCR 2.405(D). We reverse.

This case arose from a multi-vehicle accident in which plaintiff Julie Freysinger was injured. A mediation panel valued plaintiffs' claim against all defendants at $8,000. Plaintiffs then served defendants with an offer of judgment in the amount of $50,000. Defendants rejected the offer of judgment, and plaintiffs subsequently rejected the mediation award.

Shortly before trial, other defendants who are not parties to this appeal settled plaintiffs' claims against them for a total of $100,000 and were dismissed from the action. The trial proceeded against defendants, and the jury found defendants liable to plaintiffs in the amount of $150,000. The circuit court and the parties agreed that the verdict would be decreased by the $100,000 settlement with the dismissed defendants. The circuit court held, however, that the judgment was set at $150,000 for purposes of calculating interest. The circuit court further held that, because defendants had rejected the offer of judgment, they were obligated to pay plaintiffs' costs pursuant to MCR 2.405(D).

I

Defendants contend that the circuit court erred in calculating interest on the entire verdict of $150,000. This Court has consistently held that interest recoverable in a civil action pursuant to MCL 600.6013; MSA 27A.6013 is not calculated on settlement amounts. Harvey v Security Services, Inc, 148 Mich. App. 260, 271-272; 384 N.W.2d 414 (1986); Rittenhouse v Erhart, 126 Mich. App. 674, 682; 337 N.W.2d 626 (1983), modified 424 Mich. 166; 380 N.W.2d 440 (1985); Silisky v Midland-Ross Corp, 97 Mich. App. 470, 476-477; 296 N.W.2d 576 (1980); Awedian v Theodore Efron Mfg Co, 66 Mich. App. 353, 358; 239 N.W.2d 611 (1976). See also Johnson v Woodson, 109 Mich. App. 76, 79; 310 N.W.2d 898 (1981). When a plaintiff accepts a settlement, the plaintiff waives the right to prejudgment interest on that amount of the total judgment. Harvey, supra, 272.

In this case, however, the circuit court interpreted MCL 600.6306; MSA 27A.6306 as requiring that interest be calculated upon the entire $150,000 before subtracting the $100,000 settlement. MCL 600.6306; MSA 27A.6306 provides, in pertinent part:

(1) After a verdict rendered by a trier of fact in favor of a plaintiff, an order of judgment shall be entered by the court. The order of judgment shall be entered against each defendant . . . in the following order and in the following judgment amounts:

* * *

(f) All taxable and allowable costs, including interest as permitted by section 6013 and 6455 on the judgment amounts.

* * *

(3) If there is an individual who was released from liability pursuant to section 2925d, the total judgment amount shall be reduced, as provided in subsection (5), by an amount equal to the amount of the settlement between the plaintiff and that individual.

We do not interpret MCL 600.6306; MSA 27A.6306 as altering the manner of calculation of interest under MCL 600.6013; MSA 27A.6013. Under MCL 600.6306(1); MSA 27A.6306(1), the judgment amount is calculated to include interest as that interest is permitted under MCL 600.6013; MSA 27A.6013. Then, proceeding to MCL 600.6306(3); MSA 27A.6306(3), the amount of the settlement is subtracted from the total judgment. In this case, the judgment amount is $150,000. To calculate interest on this amount pursuant to MCL 600.6013; MSA 27A.6013, the $100,000 settlement must be subtracted and the interest calculated upon only defendants' $50,000 liability. See Harvey, supra, 271-272; Silisky, supra, 476-477. The interest, calculated only on the $50,000 liability pursuant to MCL 600.6013; MSA 27A.6013, is then added to the total judgment amount, as required by MCL 600.6306(1); MSA 27A.6306(1). Then, proceeding to MCL 600.6306(3); MSA 27A.6306(3), the $100,000 settlement is subtracted from the total judgment, for a judgment against defendants in the amount of $50,000, plus interest on the $50,000 as calculated under MCL 600.6013; MSA 27A.6013. The circuit court therefore erred in ordering defendants to pay interest on the entire $150,000.

II

Defendants also contend that the circuit court erred in determining that plaintiffs were entitled to costs under MCR 2.405(D), also known as the offer-of-judgment rule. The purpose of imposing costs under MCR 2.405 is to encourage parties to settle before trial. Brooks v Gough, 189 Mich. App. 623, 625; 473 N.W.2d 771 (1991). MCR 2.405(D) permits the trial court to order a party rejecting an offer of judgment to pay the opposing party's actual costs as follows, in pertinent part:

(D) Imposition of Costs Following Rejection of Offer. If an offer is rejected, costs are payable as follows:

(1) If the adjusted verdict is more favorable to the offeror than the average offer, the offeree must pay to the offeror the offeror's actual costs incurred in the prosecution or defense of the action.

(2) If the adjusted verdict is more favorable to the offeree than the average offer, the offeror must pay to the offeree the offeree's actual costs incurred in the prosecution or defense of the action. However, an offeree who has not made a counter-offer may not recover actual costs.

Similarly, with respect to mediation, MCR 2.403(O) requires a party rejecting a mediation award to pay the opposing party's actual costs unless the verdict is more favorable to the rejecting party than the mediation evaluation. MCR 2.405(E) deals with the relationship between the mediation costs provision of MCR 2.403 and the offer-of-judgment costs provision of MCR 2.405(D), and provides:

(E) Relationship to Mediation. In an action in which there has been both the rejection of a mediation award pursuant to MCR 2.403 and a rejection of an offer under this rule, the cost provisions of the rule under which the later rejection occurred control, except that if the same party would be entitled to costs under both rules costs may be recovered from the date of the earlier rejection.

This Court has consistently interpreted MCR 2.405(E) as providing that, where there are rejections under both sections, the last rejection controls for purposes of determining costs. See Magnuson v Zadrozny, 195 Mich. App. 581; 491 N.W.2d 258 (1992); Rellinger v Bremmeyr, 180 Mich. App. 661, 669; 448 N.W.2d 49 (1989); Anderson v Howley, 171 Mich. App. 210, 212-213; 429 N.W.2d 646 (1988); Coy v Richard's Industries, Inc, 170 Mich. App. 665, 674; 428 N.W.2d 734 (1988). Application of MCR 2.405(E) does not require that the rejection of the mediation award and the offer to stipulate be made by the same party. Rellinger, supra, 669.

In this case, because the mediation valuation was rejected by plaintiffs after the offer of judgment was rejected by defendants, the provisions of MCR 2.405(D) do not apply. See Magnuson, supra, 585. Defendants were therefore not obligated to pay plaintiffs' costs under the offer-of-judgment rule. We are not unsympathetic to plaintiffs' argument that, under the facts of this case and with the benefit of hindsight, the last act of defendants was to reject a reasonable offer of settlement, while the last act of plaintiffs was to reject an unreasonable mediation award. The language of MCR 2.405(E) is clear and unambiguous, however, and we will not read additional provisions into the court rule.

Reversed.
