Understanding how fault affects your ability to recover damages in a personal injury case is crucial for anyone involved in an accident. The United States employs three distinct negligence systems that vary dramatically by state, and knowing which system applies in your jurisdiction can mean the difference between full compensation, reduced recovery, or no compensation at all. Our Comparative Negligence Calculator provides an interactive way to understand these complex legal principles and see exactly how your percentage of fault impacts potential compensation.
Whether you’re involved in a car accident, slip and fall, or any other personal injury claim, the question of comparative fault will likely arise. In some states, being even 1% responsible for your injuries bars you from recovering anything. In others, you can recover damages even if you’re 99% at fault. Most states fall somewhere in between, using modified comparative negligence systems with either a 50% or 51% threshold. This calculator helps you navigate these differences by allowing you to input your damages, adjust your fault percentage, and select your state to see real-time calculations of potential recovery. Understanding these principles empowers you to make informed decisions about settlement negotiations and litigation strategy.

How to Use This Calculator
Using the Comparative Negligence Calculator is straightforward and requires just three simple inputs. First, enter the total amount of damages in dollars—this includes medical expenses, lost wages, property damage, pain and suffering, and any other compensable losses from your accident. Second, use the slider to set your percentage of fault. This represents how much responsibility you bear for causing the accident or your injuries. You can adjust this from 0% (completely not at fault) to 100% (entirely at fault). Third, select your state or jurisdiction from the dropdown menu, which includes all 50 states plus Washington D.C.
Once you’ve entered this information, the calculator instantly displays your potential recovery amount. The tool automatically applies the correct negligence rule for your selected state—whether contributory, pure comparative, or modified comparative negligence. If your state’s law bars recovery at your fault level, you’ll see a clear alert explaining why. The results section shows your recoverable amount, breaks down the calculation, and identifies which negligence system applies. Below the calculator, you’ll find detailed explanations of each negligence system with complete lists of which states follow each rule, helping you understand the legal framework that determines your compensation.

Understanding Comparative Negligence
Contributory Negligence
The strictest standard. If you are found to be even 1% at fault for your injuries, you cannot recover any damages whatsoever. This is an all-or-nothing approach that remains in only a handful of jurisdictions.
States: Alabama, Maryland, North Carolina, Virginia, and Washington D.C.
Pure Comparative Negligence
In pure comparative negligence states, you can recover damages even if you’re 99% at fault. Your recovery is simply reduced by your percentage of fault. For example, if you’re 30% at fault for $100,000 in damages, you can recover $70,000.
States: Alaska, Arizona, California, Florida, Kentucky, Louisiana, Mississippi, Missouri, New Mexico, New York, Rhode Island, Washington
Modified Comparative Negligence (50% Bar)
In these states, you can recover damages only if you’re less than or equal to 50% at fault. If you’re 51% or more at fault, you cannot recover anything. Below the threshold, your recovery is reduced by your fault percentage.
States: Arkansas, Colorado, Georgia, Idaho, Kansas, Maine, Michigan, Nebraska, North Dakota, South Dakota, Tennessee, Utah, West Virginia
Modified Comparative Negligence (51% Bar)
Similar to the 50% rule, but you can recover if you’re exactly 50% at fault. You’re barred from recovery only if you’re 51% or more at fault. This is sometimes called the “not greater than” rule.
States: Connecticut, Delaware, Hawaii, Illinois, Indiana, Iowa, Massachusetts, Minnesota, Montana, Nevada, New Hampshire, New Jersey, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Texas, Vermont, Wisconsin, Wyoming
