Statute of Limitations Calculator

The Statute of Limitations Calculator helps you estimate the deadline to file a legal claim. Pick your case type and U.S. state, enter the date the incident happened or the date you discovered the harm, and the tool looks up the limitations period for that exact combination, counts forward to the filing deadline, and shows how much time is left on an animated timeline. It covers nine common claim types across all 50 states and Washington, D.C.

What Is a Statute of Limitations?

A statute of limitations is a law that sets the maximum time after an event within which you can start a lawsuit. Once the clock runs out, the court will normally refuse to hear the case — even a strong claim is lost simply because it was filed too late. The purpose is fairness: evidence fades, memories blur, and people deserve to move on without the indefinite threat of being sued. The length of the deadline depends on two things: the type of claim and the state whose law applies.

How the Filing Deadline Is Calculated

Calculating a statute of limitations deadline takes three short steps:

1. Find the limitations period for your claim type in your state — for example, two years for personal injury or four years for a written contract.
2. Identify the start date — usually the date of the incident, or, under the discovery rule, the date you discovered the harm.
3. Count that many years forward from the start date. The resulting date is the last day to file.

For instance, a two-year personal injury claim that arose on June 1, 2025 would generally have to be filed by June 1, 2027. The calculator handles fractional periods, such as a two-and-a-half-year medical malpractice deadline, by adding the matching number of months.

When Does the Clock Start? The Discovery Rule

For many claims, the clock starts on the day the harm happened. But for some claims a discovery rule applies, meaning the clock starts only when the injury was — or reasonably should have been — discovered. This often matters when harm is hidden, such as a surgical sponge left inside a patient, a slow-developing illness, or fraud that surfaces years later. Because the right rule depends on the claim and the state, this calculator lets you count from either the incident date or the discovery date so you can compare both.

Typical Limitations Periods by Case Type

The most common claim types and their usual ranges across states are below. The exact number varies by state — the calculator uses the value for the state you select.

What Can Pause or Extend the Deadline?

Several rules, collectively called tolling, can pause or extend a statute of limitations. The calculator does not account for these, so treat its result as a baseline only.

How to Use This Calculator

1. Choose the case type: Select the kind of claim, such as personal injury, contract, debt, fraud, or medical malpractice.
2. Choose your state: Pick the U.S. state or Washington, D.C. whose law applies to your claim.
3. Enter the start date: Enter the date of the incident, or the date you discovered the harm, and choose which one the clock should count from.
4. Review your deadline: See the filing deadline, the animated timeline of your filing window, the countdown of time remaining, and the urgency status.

Frequently Asked Questions

What is a statute of limitations?

A statute of limitations is a law that sets the maximum time after an event within which legal proceedings may be started. Once that period passes, a court will usually dismiss the case no matter how strong it is, so the deadline effectively ends your right to sue. The length of the period depends on the type of claim and the state where it is filed.

How is the filing deadline calculated?

The calculator looks up the limitations period for your case type and state, then counts that many years forward from your chosen start date. For example, a two-year personal injury claim that arose on June 1, 2025 would generally have to be filed by June 1, 2027. Fractional periods, such as two and a half years, are added as the matching number of months.

When does the statute of limitations clock start?

For many claims the clock starts on the date of the incident. For some claims a discovery rule applies, so the clock instead starts when the harm was, or reasonably should have been, discovered. This often matters for medical malpractice, fraud, and hidden defects. Which rule applies depends on the claim and the state, so this tool lets you count from either date.

What happens if the statute of limitations expires?

If you file after the deadline, the opposing party can ask the court to dismiss the case, and it usually will. There are exceptions that can pause or extend the clock, but you cannot rely on them. If your deadline is close or appears to have passed, contact an attorney immediately because some exceptions are time-sensitive themselves.

Can the statute of limitations deadline be extended or paused?

Sometimes. The clock can be paused, or tolled, in situations such as the injured person being a minor or legally incapacitated, the defendant leaving the state or concealing wrongdoing, or fraud being discovered late. Special shorter notice deadlines also apply to many claims against government agencies. These rules are complex and vary by state, so only an attorney can confirm your actual deadline.

Is this calculator legal advice?

No. This calculator provides general information using common default limitations periods, and it does not account for tolling, discovery rules, government-claim notice deadlines, or recent changes in the law. It is not legal advice and does not create an attorney-client relationship. Always confirm your specific deadline with a licensed attorney in your jurisdiction before relying on any date.
