This calculator gives a rough, educational estimate of potential civil damages for false arrest or unlawful detention. It focuses on typical components in U.S. cases: lost income while you were detained, other economic losses, and an approximate amount for emotional distress and loss of liberty.
Courts do not use a single mathematical formula to set damages. Judges and juries weigh many facts and the law of the specific state or jurisdiction. Use this tool as a starting point for understanding how different factors can affect a rough estimate, not as a prediction of what any court will award.
False arrest (sometimes called false imprisonment or unlawful detention) generally refers to being restrained, arrested, or held without proper legal authority. In the United States, these situations may lead to:
This page is written primarily with U.S. law in mind. Laws, procedures, and available damages vary by country and by state. If your situation happened outside the United States, or in a specific U.S. state, you should speak with a local attorney for jurisdiction-specific advice.
The calculator combines three main pieces of information you enter:
In simplified form, the calculator follows this structure:
Where:
Lost income is estimated as:
Where is hours detained and is your hourly wage.
Non-economic damages are estimated by applying a rough multiplier to your economic losses. Higher multipliers reflect more serious emotional harm, longer detention, or more humiliating circumstances. The scale is typically interpreted as:
The calculator then adds these components together to produce a single rough estimate.
Reported verdicts and settlements vary widely, but the ranges below are often cited as broad, non-binding reference points for U.S. cases. They are not guarantees and do not replace professional legal analysis.
| Detention type | Approximate duration | Typical reported range (USD) |
|---|---|---|
| Brief street detention | 1โ4 hours | $5,000 โ $25,000 |
| Overnight jail | 12โ24 hours | $15,000 โ $50,000 |
| Multi-day detention | 2โ7 days | $30,000 โ $150,000 |
| Extended wrongful imprisonment | Weeks to months | $100,000 โ $1,000,000+ |
Your situation may fall outside these ranges depending on the facts, local law, available evidence, and any caps on damages.
When judges or juries decide damages in false arrest and unlawful detention cases, they usually consider a combination of factors, including:
Imagine the following scenario, using the default values in the calculator:
First, estimate lost income:
10 hours ร $25/hour = $250 in lost wages.
Economic losses are then:
$250 (lost wages) + $1,000 (other economic losses) = $1,250.
Using a multiplier of 3, non-economic damages are roughly estimated as 3 ร $1,250 = $3,750.
The total estimated damages would be:
$1,250 (economic) + $3,750 (non-economic) = $5,000.
This figure is a rough educational estimate. An attorney might adjust it up or down based on the specific facts, evidence, applicable law, and any statutory caps.
When you run the calculator, you will typically see:
Use this output to:
Do not use the result to decide whether to file a claim, settle, or reject a settlement offer without professional advice. Real-world outcomes can be higher or lower than this estimate.
| Aspect | Calculator estimate | Real-world court or settlement value |
|---|---|---|
| Method | Simple formula using your inputs and a chosen multiplier. | Fact-intensive analysis by lawyers, insurers, judges, or juries. |
| Data used | Hours detained, wage, economic losses, distress multiplier. | Police reports, medical records, witness testimony, expert opinions, local case law, and more. |
| Variability | Only changes when you adjust the inputs. | Affected by evidence strength, credibility, jurisdiction, and negotiation strategy. |
| Precision | Approximate educational number, not a prediction. | Final judgment or settlement figure, sometimes confidential. |
| Use case | Learning tool and rough planning aid. | Legally binding resolution of a dispute. |
This calculator is intentionally simplified. It relies on several important assumptions:
This tool is for general informational and educational purposes only and is not legal advice.
If you believe you were falsely arrested or unlawfully detained, you should consult a qualified attorney in your jurisdiction as soon as possible to evaluate your potential claims and any filing deadlines.
Yes. Dropped or dismissed charges often support false arrest claims, suggesting prosecutors found insufficient evidence. However, dismissal doesn't automatically prove false arrestโofficers may have had probable cause at arrest time even if prosecution couldn't prove guilt beyond reasonable doubt. The key is whether arrest was supported by probable cause when made, not whether charges stuck.
Qualified immunity protects government officials including police officers from liability unless they violated clearly established constitutional rights that a reasonable officer would have known. This defense bars many false arrest claims even when arrest was objectively unlawful, if the law wasn't clearly established. Recent reforms have limited qualified immunity in some jurisdictions, but it remains a significant hurdle in civil rights cases.
