Before: MURPHY, P.J., and CAVANAGH and CONNOR, JJ.
CONNOR, J.
We granted defendants' application for leave to appeal from the February 14, 1990, order of the trial court denying defendants' motion for partial summary disposition that alleged that plaintiffs' action was time-barred for certain members of the plaintiff class. We reverse the trial court's order denying summary disposition.
On January 1, 1984, defendant City of Allen Park amended its retirement plan, increasing the level of benefits. Before that time, persons retiring, and particularly those terminating their service with the city and accepting a lump-sum distribution of vested benefits, received the money contributed by the city to the plan, plus interest at three percent a year. In this suit, plaintiffs contend that the rate of interest was much lower than the rate *105 of earnings actually generated by investments made by the defendant retirement board.
Plaintiffs filed this case as a class action involving two groups. One group is comprised of those employees who retired from city employment before July 1, 1983, and receive periodic pension benefits. This group is represented by plaintiffs Harris, Bessel, Miner, and Tauck (Harris group). The other group includes those former employees, represented by plaintiffs Sharp and Wigginton (Sharp group), who left city employment before retirement and received lump-sum payments of their contributions to the retirement system.
It is plaintiffs' claim that the interest from their contributions was used to increase the size of the retirement fund as a whole. This alleged misappropriation of contributed funds was then used to award increased pension benefits to those persons who retired from the city after June 1983 on the basis of changes in the terms of the retirement system that became effective in January 1984. It was alleged in plaintiffs' complaint that defendants breached contractual rights and violated fiduciary duties by not paying plaintiffs all the interest generated from their individual contributions to the retirement system.
Defendants filed a motion for partial summary disposition under MCR 2.116(C)(7), arguing that the six-year period of limitation for contract actions, MCL 600.5807(8); MSA 27A.5807(8), barred the actions of those plaintiffs who received lumpsum payments, the Sharp group, six years before this action was filed. Similarly, the defendants argued that any payments of periodic benefits to plaintiffs in the Harris group made six years before this case was filed would also be time-barred.
In opposition to the motion, plaintiffs argued that their cause of action did not accrue until *106 January 1, 1984, when the increased benefits to subsequent retirees went into effect. In support of their motion, plaintiffs relied upon the provisions of the city charter and collective bargaining agreements produced by defendants.
On the basis of plaintiffs' complaint, the trial court agreed that the cause of action did not accrue until January 1984. Accordingly, the motion for summary disposition was denied.
Defendants argued below that summary disposition was available under MCR 2.116(C)(7). When reviewing a motion under that rule, the plaintiff's well-pleaded allegations are accepted as true and are construed in the plaintiff's favor. Kassab v Michigan Basic Property Ins Ass'n, 185 Mich App 206, 210; 460 NW2d 300 (1990), lv gtd 439 Mich 864 (1991). If the pleadings demonstrate that a party is entitled to judgment as a matter of law, or if affidavits or other documentary evidence show that there is no genuine issue of material fact, the trial court must render judgment without delay. Paterek v 6600 Limited, 186 Mich App 445, 447; 465 NW2d 342 (1990). If no facts are in dispute, whether the claim is statutorily barred is a question for the court as a matter of law. Kassab, supra, p 211.
A claim accrues, for purposes of the statute of limitations, when suit may be brought. Smith v Dep't of Treasury, 163 Mich App 179, 183; 414 NW2d 374 (1987). For contract actions, the period of limitation generally begins to run on the date of the breach of the contract. In re Easterbrook Estate, 114 Mich App 739, 748; 319 NW2d 655 (1982). A plaintiff need not know of the invasion of a legal right in order for the claim to accrue. Thomas v Process Equipment Corp, 154 Mich App 78, 87; 397 NW2d 224 (1986).
In reviewing the arguments made in support of *107 summary disposition below and the documentary evidence offered, we believe the trial court incorrectly determined that plaintiffs' cause of action did not accrue until January 1984. Plaintiffs' action is based on allegations that retirees after January 1984 benefited from interest generated by plaintiffs' contributions to the retirement fund. The wrongful conduct alleged is not the payment of increased benefits to post-1984 retirees, but the misappropriation of interest earned by plaintiffs, which occurred well before 1984 according to plaintiffs' complaint. The cause of action accrued when the funds plaintiffs claim they were entitled to were not paid, not when defendants allegedly gave this misappropriated amount to post-1984 retirees by changing the terms of the retirement system. Accordingly, as a matter of law, the trial court should have granted partial summary disposition and dismissed those plaintiffs who received lump-sum payments before October 23, 1981 (six years before this action was filed), and those plaintiffs who retired from the system and are seeking damages for periodic pension payments made before October 23, 1981. However, not all individuals who retired from the system more than six years before this action was filed should have their claims barred. Pension benefits are similar to installment contracts and the period of limitation runs from the date each installment is due. Therefore, every periodic payment made that is alleged to be less than the amount due plaintiffs in the Harris group constitutes a continuing breach of contract and the limitation period runs from the due date of each payment. See Bishop v State of Florida, Division of Retirement, 413 So 2d 776, 778 (Fla App, 1982); Trustees for Alaska Laborers  Construction Industry Health & Security Fund v Ferrell, 812 F2d 512, 517 (CA 9, 1987).
*108 On remand, the trial court should determine which individual plaintiffs are now barred from this case in whole or in part because of the statute of limitations.
Reversed and remanded for action consistent with this opinion. We do not retain jurisdiction.
