Comparative Negligence Calculator
When an insurance company assigns you a percentage of fault, it directly reduces — or eliminates — what you can recover. This calculator shows exactly how your state's fault rules affect your case, and why that percentage is never final.
You can recover even if 99% at fault. Recovery reduced by your exact fault %.
Recovery barred if you are 51% or more at fault. Below that, proportional reduction.
51% fault = $0
Recovery barred at exactly 50% fault or more. Stricter than the 51% rule.
50% fault = $0
Any fault at all — even 1% — completely bars all recovery. Used in 5 jurisdictions.

ⓘ The same accident, the same injuries, the same fault percentage — but a wildly different outcome depending on where it happened. This is why the state of your accident and the fault percentage assigned to you are two of the most important factors in your case.

The Fault Percentage Is Not Final
Insurance companies assign fault percentages to minimize payouts — not to accurately reflect what happened. An experienced personal injury attorney can challenge the assigned percentage, present counter-evidence, and negotiate a lower fault finding that dramatically increases your recovery.
