Missouri prejudgment interest is claim-specific. Qualifying non-tort obligations may use the 9% rule in §408.020. The current numeric tort rate is withheld because §408.040 refers to the ‘intended Federal Funds Rate’ and the reviewed Federal Reserve publications do not establish whether that means a target-bound or effective-rate value. StatuteRates will not substitute a plausible number.
When Missouri prejudgment interest applies
Prejudgment interest is NOT freely available; it is claim-type restricted.
When it starts accruing
TORT (§ 408.040.2): accrues from a date 90 days AFTER the demand/offer was received (per certified-mail return receipt), OR from the date the demand/offer was rejected without a counteroffer, whichever is earlier.
Simple or compound
The current tort benchmark is unresolved, and this page does not provide a calculator method for that branch. Confirm the controlling order and statute for any non-tort calculation as well.
How the rate is set
Do not treat the two Missouri formulas as interchangeable or choose a target-bound/effective-rate proxy. Section 408.040.3 refers to the intended Federal Funds Rate plus five points for the tort judgment; subsection .4 separately addresses the prejudgment-interest portion after judgment. The numeric tort result remains unavailable pending authoritative clarification.
→ Compare with the Missouri post-judgment interest rate (interest after judgment)
Liquidated or contract claims may bear 9% under § 408.020. For qualifying tort claims, § 408.040.3 awards prejudgment interest within the subsection that sets the tort judgment rate at the intended Federal Funds Rate plus 5 points. Section 408.040.4 separately says the judgment for prejudgment interest bears Federal Funds plus 3 points after entry. Because those are distinct stages, this reference record does not flatten the tort rule into one headline percentage. Not legal advice.
