Section 600.6013 - Interest on money judgment(1) Interest is allowed on a money judgment recovered in a civil action, as provided in this section. However, for complaints filed on or after October 1, 1986, interest is not allowed on future damages from the date of filing the complaint to the date of entry of the judgment. As used in this subsection, "future damages" means that term as defined in section 6301.(2) For complaints filed before June 1, 1980, in an action involving other than a written instrument having a rate of interest exceeding 6% per year, the interest on the judgment is calculated from the date of filing the complaint to June 1, 1980, at the rate of 6% per year and on and after June 1, 1980, to the date of satisfaction of the judgment at the rate of 12% per year compounded annually.(3) For a complaint filed before June 1, 1980, in an action involving a written instrument having a rate of interest exceeding 6% per year, the interest on the judgment is calculated from the date of filing the complaint to the date of satisfaction of the judgment at the rate specified in the instrument if the rate was legal at the time the instrument was executed. However, the rate after the date judgment is entered shall not exceed either of the following: (a) Seven percent per year compounded annually for a period of time between the date judgment is entered and the date of satisfaction of the judgment that elapses before June 1, 1980.(b) Thirteen percent per year compounded annually for a period of time between the date judgment is entered and the date of satisfaction of the judgment that elapses after May 31, 1980.(4) For a complaint filed on or after June 1, 1980, but before January 1, 1987, interest is calculated from the date of filing the complaint to the date of satisfaction of the judgment at the rate of 12% per year compounded annually unless the judgment is rendered on a written instrument having a higher rate of interest. In that case, interest is calculated at the rate specified in the instrument if the rate was legal at the time the instrument was executed. The rate under this subsection shall not exceed 13% per year compounded annually after the date judgment is entered.(5) Except as provided in subsection (6), for a complaint filed on or after January 1, 1987, but before July 1, 2002, if a judgment is rendered on a written instrument, interest is calculated from the date of filing the complaint to the date of satisfaction of the judgment at the rate of 12% per year compounded annually, unless the instrument has a higher rate of interest. In that case, interest shall be calculated at the rate specified in the instrument if the rate was legal at the time the instrument was executed. The rate under this subsection shall not exceed 13% per year compounded annually after the date judgment is entered.(6) For a complaint filed on or after January 1, 1987, but before July 1, 2002, if the civil action has not resulted in a final, nonappealable judgment as of July 1, 2002, and if a judgment is or has been rendered on a written instrument that does not evidence indebtedness with a specified interest rate, interest is calculated as provided in subsection (8).(7) For a complaint filed on or after July 1, 2002, if a judgment is rendered on a written instrument evidencing indebtedness with a specified interest rate, interest is calculated from the date of filing the complaint to the date of satisfaction of the judgment at the rate specified in the instrument if the rate was legal at the time the instrument was executed. If the rate in the written instrument is a variable rate, interest shall be fixed at the rate in effect under the instrument at the time the complaint is filed. The rate under this subsection shall not exceed 13% per year compounded annually.(8) Except as otherwise provided in subsections (5) and (7) and subject to subsection (13), for complaints filed on or after January 1, 1987, interest on a money judgment recovered in a civil action is calculated at 6-month intervals from the date of filing the complaint at a rate of interest equal to 1% plus the average interest rate paid at auctions of 5-year United States treasury notes during the 6 months immediately preceding July 1 and January 1, as certified by the state treasurer, and compounded annually, according to this section. Interest under this subsection is calculated on the entire amount of the money judgment, including attorney fees and other costs. In an action for medical malpractice, interest under this subsection on costs or attorney fees awarded under a statute or court rule is not calculated for any period before the entry of the judgment. The amount of interest attributable to that part of the money judgment from which attorney fees are paid is retained by the plaintiff, and not paid to the plaintiff's attorney.(9) If a bona fide, reasonable written offer of settlement in a civil action based on tort is made by the party against whom the judgment is subsequently rendered and is rejected by the plaintiff, the court shall order that interest is not allowed beyond the date the bona fide, reasonable written offer of settlement is filed with the court.(10) Except as otherwise provided in subsection (1) and subject to subsections (11) and (12), if a bona fide, reasonable written offer of settlement in a civil action based on tort is not made by the party against whom the judgment is subsequently rendered, or is made and is not filed with the court, the court shall order that interest be calculated from the date of filing the complaint to the date of satisfaction of the judgment.(11) If a civil action is based on medical malpractice and the defendant in the medical malpractice action failed to allow access to medical records as required under section 2912b(5), the court shall order that interest be calculated from the date notice was given in compliance with section 2912b to the date of satisfaction of the judgment.(12) If a civil action is based on medical malpractice and the plaintiff in the medical malpractice action failed to allow access to medical records as required under section 2912b(5), the court shall order that interest be calculated from 182 days after the date the complaint was filed to the date of satisfaction of the judgment.(13) Except as otherwise provided in subsection (1), if a bona fide, reasonable written offer of settlement in a civil action based on tort is made by a plaintiff for whom the judgment is subsequently rendered and that offer is rejected and the offer is filed with the court, the court shall order that interest be calculated from the date of the rejection of the offer to the date of satisfaction of the judgment at a rate of interest equal to 2% plus the rate of interest calculated under subsection (8).(14) A bona fide, reasonable written offer of settlement made according to this section that is not accepted within 21 days after the offer is made is rejected. A rejection under this subsection or otherwise does not preclude a later offer by either party.(15) As used in this section: (a) "Bona fide, reasonable written offer of settlement" means either of the following:(i) With respect to an offer of settlement made by a defendant against whom judgment is subsequently rendered, a written offer of settlement that is not less than 90% of the amount actually received by the plaintiff in the action through judgment.(ii) With respect to an offer of settlement made by a plaintiff, a written offer of settlement that is not more than 110% of the amount actually received by the plaintiff in the action through judgment.(b) "Defendant" means a defendant, a counter-defendant, or a cross-defendant.(c) "Party" means a plaintiff or a defendant.(d) "Plaintiff" means a plaintiff, a counter-plaintiff, or a cross-plaintiff.Amended by 2012, Act 609,s 3, eff. 3/28/2013.1961, Act 236, Eff. 1/1/1963 ;--Am. 1965, Act 240, Imd.
