After an injury caused by someone else’s negligence, one of the first questions you probably have is: how much can I actually recover? The answer depends heavily on which state you live in — because each state has its own rule about what happens when you share some of the blame.

This page explains the three main negligence systems used across the United States and gives you a free calculator to estimate your potential recovery based on your state’s rules.

The Three Negligence Systems

Pure Comparative Negligence is used in states like California, New York, and Florida. Under this system, your damages are simply reduced by your percentage of fault. If you were 30% at fault and suffered $100,000 in damages, you recover $70,000. Even a plaintiff who is 90% at fault can still recover 10% of their damages.

Modified Comparative Negligence is the most common system. Most states use a threshold — either 50% or 51%. If your fault exceeds that threshold, you are completely barred from recovering anything. If your fault is below the threshold, your damages are reduced proportionally.

Pure Contributory Negligence is the harshest rule and is only used in a handful of states: Alabama, Maryland, North Carolina, Virginia, and Washington D.C. Under this rule, even 1% fault on your part can completely eliminate your right to recover. If you live in one of these states and share any blame, consulting an attorney is especially important — exceptions like the “last clear chance” doctrine sometimes apply.

How Attorney Fees Work

Most personal injury attorneys work on a contingency fee basis, meaning they charge a percentage of your recovery — typically around 33% — and collect nothing if you lose. This makes legal representation accessible even when you cannot afford hourly rates. The calculator estimates your net recovery after a standard 33% contingency fee.

Use the Calculator

Enter your total damages (economic and non-economic combined), your estimated percentage of fault, and your state. The calculator will apply your state’s specific negligence rule and show you an estimated recovery range.

Important: This calculator is for educational purposes only. It is NOT legal advice. Fault percentages in actual cases are determined by courts, juries, or negotiated settlements. Consult a licensed personal injury attorney in your state for advice on your specific case.

What the Calculator Cannot Tell You

This tool is intentionally simplified. Real personal injury cases involve factors the calculator cannot account for:

  • Disputed fault: The other party may argue your actual fault percentage is higher than you believe
  • Multiple defendants: Fault may be spread across several parties
  • Damage caps: Some states limit non-economic damages in certain case types (medical malpractice, for example)
  • Insurance policy limits: Even a large calculated recovery may be limited by the at-fault party’s coverage
  • Liens and subrogation: Medical insurers, Medicare, and Medicaid may have claims against your settlement
  • Punitive damages: In cases of egregious misconduct, courts may award additional punitive damages not reflected here

These factors make attorney consultation not just helpful but often essential. Most personal injury attorneys offer free initial consultations and only get paid if you recover — so there is no financial risk in getting a professional opinion.

Frequently Asked Questions

Can I still sue if I was partly at fault?

Yes, in most states — as long as your fault does not exceed the threshold. In pure comparative negligence states, you can always recover something. An attorney can help you understand how fault is likely to be apportioned in your specific case.

What if the other driver had no insurance?

Your own Uninsured Motorist (UM) coverage steps in. The same comparative negligence rules apply to UM claims. An experienced attorney can help you maximize recovery from your own policy.

How long do I have to file a claim?

Statutes of limitations for personal injury claims typically range from one to six years depending on the state and the type of claim. Government entity claims often require a “notice of claim” within just 30 to 90 days of the incident. Do not wait — contact an attorney promptly.
