The multiplier method is a rough starting point, not a guarantee. Slip-and-fall value depends most on proving the owner's fault and on the available insurance. An attorney is the only way to value your specific claim. This tool is not legal advice and RecordingLaw.com is not a law firm.
How the Estimate Works
No tool can predict a slip-and-fall settlement. This calculator applies the multiplier method (pain and suffering as a multiple of your medical bills), then does something the thin online calculators skip: it weighs how provable the owner's fault is. A spill the staff caused or knew about is worth far more than a hazard nobody can show the owner knew about. It then estimates your own comparative fault from a few plain questions and applies Missouri's rules.
Proving the Owner Was at Fault
Premises liability has four parts: a dangerous condition existed, the owner knew or should have known about it, they failed to fix it or warn you, and that caused your injury. The middle part — notice — is where most slip-and-fall cases are won or lost. Strong evidence (an incident report, photos of the hazard, surveillance video, cleaning and maintenance logs, prior complaints) is what turns a claim from a token offer into real money. A posted warning sign or cone works against you: it shows the owner did warn, and it makes the hazard "open and obvious," shifting fault onto you.
Missouri Premises-Liability Rules
Open-and-obvious hazards. In Missouri, an open-and-obvious hazard is only a comparative-fault factor (it reduces, not bars). Missouri does NOT make an open-and-obvious hazard an automatic bar to a premises-liability claim. Following the Restatement (Second) of Torts § 343A, the Missouri Supreme Court in Harris v. Niehaus, 857 S.W.2d 222 (Mo. banc 1993), held that a possessor of land can still be liable for a known or obvious danger where the possessor should anticipate the harm despite its obviousness. The obviousness of the condition does not negate duty outright; instead it bears on (a) whether the possessor should have anticipated the harm and (b) the plaintiff's own comparative fault. Because Missouri applies pure comparative fault, the visitor's failure to avoid an obvious hazard reduces but does not necessarily eliminate recovery. (The older absolute open-and-obvious defense was largely displaced after Missouri adopted comparative fault in Gustafson v. Benda, 661 S.W.2d 11 (Mo. banc 1983).)
Ice and snow. Missouri follows the natural-accumulation rule — a property owner generally owes NO duty to remove naturally accumulated ice or snow, so those claims are hard to win unless the accumulation was unnatural or the owner made it worse. Missouri follows the "Massachusetts Rule": a landowner generally owes NO duty to remove snow or ice that has accumulated naturally and is a condition general to the community. Notably, Missouri continues to apply this rule even though Massachusetts itself abandoned the natural/unnatural distinction in 2010. See Willis v. Springfield General Osteopathic Hospital, 804 S.W.2d 416 (Mo. App. S.D. 1991), and Maschoff v. Koedding, 439 S.W.2d 234 (Mo. App. 1969). Liability attaches only on recognized exceptions: (1) UNNATURAL accumulation created or worsened by the owner (e.g., snow piled so meltwater refreezes on a walkway); (2) NEGLIGENT removal that creates a new hazard (e.g., leaving black ice after clearing); or (3) a duty VOLUNTARILY ASSUMED by agreement or a consistent course of conduct of clearing the property.
Public property. If you fell on government property, Missouri requires a formal notice of claim — often within about 90 days, much shorter than the normal deadline. For the most common municipal slip-and-fall scenario — an injury from a defect or dangerous condition of a city street, sidewalk, thoroughfare, boulevard, or bridge — Missouri requires WRITTEN notice to the mayor within NINETY (90) days of the occurrence before suit may be maintained against the city: Mo. Rev. Stat. § 82.210 (applies to cities of 100,000 or more; notice to the mayor "within ninety days of the occurrence," stating the place, time, and character/circumstances of the injury, and that the claimant will seek damages). The Missouri Tort Claims Act waiver for dangerous conditions of public property (§ 537.600.1(2)) contains no separate notice deadline, so the 90-day § 82.210 city-notice requirement is120).
Your Fault & the Deadline to File
Missouri follows pure comparative negligence. Your award is reduced by your share of fault, but you can still recover something even if you were mostly at fault.
Missouri follows PURE comparative fault: a plaintiff's recovery is reduced by their percentage of fault but is never barred, even if the plaintiff is more than 50% (or up to 99%) at fault. The Missouri Supreme Court adopted pure comparative fault for negligence in Gustafson v. Benda, 661 S.W.2d 11 (Mo. banc 1983), replacing the old contributory-negligence bar. For products liability it is codified at RSMo 537.765, which abolishes contributory fault as a complete bar and reduces compensatory damages proportionately. The dog-bite statute (273.036) likewise reduces, rather than bars, damages by the injured party's fault percentage.
Missouri generally requires a slip-and-fall lawsuit to be filed within 5 years of the fall (the statute of limitations). RSMo 516.120(4) sets a 5-year limitation for "any other injury to the person or rights of another, not arising on contract." This is the standard period for negligence-based personal-injury claims (auto, premises, dog bite). Note: wrongful death is 3 years (RSMo 537.100), and some intentional torts have a 2-year period (RSMo 516.140). Source: Harris v. Niehaus, 857 S.W.2d 222 (Mo. banc 1993) (open-and-obvious / Restatement (Second) § 343A); Gustafson v. Benda, 661 S.W.2d 11 (Mo. banc 1983) (pure comparative fault); Willis v. Springfield Gen. Osteopathic Hosp., 804 S.W.2d 416 (Mo. App. S.D. 1991) & Maschoff v. Koedding, 439 S.W.2d 234 (Mo. App. 1969) (natural-accumulation / Massachusetts Rule); Mo. Rev. Stat. §§ 82.210, 537.600, 516.120.
- Missouri uses PURE comparative fault (Gustafson v. Benda, 661 S.W.2d 11 (Mo. banc 1983)): a slip-and-fall plaintiff's recovery is reduced by their own percentage of fault but is never wholly barred, even if mostly at fault.
- Open-and-obvious is NOT an automatic defense. Under Harris v. Niehaus and Restatement (Second) § 343A, a landowner can still be liable for an obvious danger when the harm should have been anticipated; obviousness mainly goes to comparative fault.
- Naturally accumulated ice and snow generally creates NO landowner duty (Massachusetts Rule). Recovery requires an unnatural accumulation, negligent snow/ice removal, or a duty the owner voluntarily assumed.
- Falls on city streets or sidewalks require WRITTEN notice to the mayor within 90 days (Mo. Rev. Stat. § 82.210) before suing the municipality — a trap separate from the 5-year filing deadline.
- The general personal-injury statute of limitations is 5 years (Mo. Rev. Stat. § 516.120), but the 90-day municipal notice deadline can extinguish a claim against a city long before that.
Frequently Asked Questions
How much is my Missouri slip and fall claim worth?
No one can tell you a number in advance, and slip-and-fall is harder than a car accident because you must prove the owner was at fault. A rough estimate adds your economic damages and a pain-and-suffering multiplier, discounts it by how provable the owner's fault is, and reduces it for your share of fault under Missouri's pure comparative negligence rule. The available insurance also caps recovery — an attorney is the only way to value your specific case.
Does a "wet floor" sign hurt my Missouri claim?
Yes, usually. A posted warning shows the owner satisfied part of their duty to warn and makes the hazard "open and obvious," which shifts fault onto you. In Missouri, an open-and-obvious hazard is only a comparative-fault factor (it reduces, not bars). It reduces — and sometimes defeats — a claim, but not always (a hidden or inadequate sign may not help the owner).
Can I sue for a fall on ice or snow in Missouri?
It's difficult. Missouri follows the natural-accumulation rule, so a landowner generally owes no duty to remove naturally accumulated ice or snow. You'd usually need to show the accumulation was unnatural or the owner made it worse. This is general information, not legal advice — consult a Missouri attorney.
How long do I have to file in Missouri?
Generally 5 years from the fall. If you fell on public property, a much shorter notice-of-claim deadline (around 90 days) applies first. RSMo 516.120(4) sets a 5-year limitation for "any other injury to the person or rights of another, not arising on contract." This is the standard period for negligence-based personal-injury claims (auto, premises, dog bite). Note: wrongful death is 3 years (RSMo 537.100), and some intentional torts have a 2-year period (RSMo 516.140).
Is this calculator accurate?
It is a rough estimate to show the factors that drive value — not a prediction or an offer. Slip-and-fall outcomes vary enormously and depend on proving fault and on the available insurance. Treat any number here as a ballpark and consult a Missouri attorney.
