Cost Of Delay in Missouri

Under Missouri law, the cost of delay on a money judgment is set at 9% per year. This rate is established by Mo. Rev. Stat. § 408.020, which governs the legal rate of interest, and is applied to judgments under the variable judgment rate statute (§ 408.040). The 9% figure is the fixed rate that accrues on the unpaid principal from the date the judgment is entered until it is satisfied. The statute does not require a separate motion; interest accrues automatically by operation of law. The worked example below demonstrates how this rate is applied over time. To estimate the interest owed on a specific judgment, use the DocketMath calculator with the official source linked for the exact statutory language.
