What this guide is best for
Direct answer: A settlement calculator returns a number from the handful of things you typed, and the things that actually move a settlement are mostly not among them. Treat the output as a prompt for questions, never as an estimate.
Best used when: You have run a figure through an online estimator and want to work out what it could and could not have known before you rely on it.
Quick answer
An online estimator takes four or five inputs and returns a figure to the dollar. The precision is decoration. Nothing the tool was given tells it which state's law applies, how fault will be allocated, whether treatment is finished, or whether the documents behind the medical total will survive scrutiny.
That does not make every calculator dishonest. It makes the output a formatted restatement of your own inputs, and there is a short way to check exactly how much it left out.
Timing: why an early estimate is the least reliable one
Most people reach an estimator in the first days after an incident, when the least is known. Treatment is ongoing, records have not been gathered, and time away from work has not been totalled.
The early days are urgent for a different reason. Photographs, witness details, the incident report and the first medical contact are all easier to capture now than to reconstruct later, and they are what any real figure will eventually be argued from.
Deadlines to bring a claim vary by state and by claim type, and no calculator knows yours. Take that question to qualified counsel for your own state.
What it asked for against what actually decides it
| What the tool asked you | What that line actually turns on | Knowable when you typed it? |
|---|---|---|
| Total medical bills | Whether the billed figure or the accepted figure is used, and whether treatment has ended | No, not until records and benefit statements are gathered |
| Type of accident | Which policies and which parties are actually in the claim | Rarely, at that stage |
| Injury severity, chosen from a list | A treating physician's written findings and prognosis | No |
| Whether you were at fault, yes or no | How a claimant's share of fault is treated, which is a state-law question and differs by state | No, and the tool did not ask which state |
| Days of work missed | Pay records, employer confirmation, and whether the absence is documented as related | Partly |
| Nothing was asked about | Available insurance limits, liens against the recovery, the identity of every defendant | These often set the ceiling |
Read the bottom row twice. A figure produced without any question about coverage or liens is a figure produced without the two constraints most likely to determine what is actually available.
A checklist for auditing any estimator
- Does it name a source for its method, or only assert one?
- If it multiplies a medical total by a factor, does it say where that factor comes from? No published authority for that convention is named anywhere in this site's sources.
- Did it ask which state the claim arises in? If not, it cannot have applied any state's rules.
- Did it ask about insurance limits or liens? If not, it has no ceiling and no deductions.
- Did it ask whether treatment has finished?
- Does the page say who operates it, and whether the operator sells or buys enquiries?
- What happens to the details you typed in — is there a stated retention and sharing policy?
- Does it present a range with a stated basis, or a single figure to the dollar?
Meanwhile, keep the documents. Photograph bills, records, correspondence and pay records as they arrive, and keep a dated timeline. Those are the inputs a real figure is built from.
Questions to ask a person, not a form
- Which line items in my claim are closed, and which are still open?
- Which state's law governs this claim, and what does that change?
- What insurance is available, and has anyone confirmed the limits?
- Which liens are expected against any recovery, and who negotiates them?
- What would you need to see before you would put any range on this at all?
The construction of the figure itself is set out in what a fair settlement figure is made of.
Cautions
Do not repeat a calculator's number to an insurer or an attorney as though it were a valuation. It anchors a conversation to a figure with nothing behind it, and it can anchor it low.
Be careful with a tool that asks for your phone number before it will show the result. At that point the number is the price of the enquiry, not the output of a method.
Slow down if a result arrives with urgency attached — a countdown, a warning that a figure expires, a prompt to call immediately. Be cautious about entering medical detail into any form that does not say who receives it.
What to do next
Run the audit checklist against whatever tool you used and note which rows it failed. Take those gaps — state, coverage, liens, whether treatment has ended — to a person who can answer them, and treat the calculator output as discarded once you have.
