Pain & Suffering

Work out what the published multiplier and per-diem methods produce from your medical bills, projected treatment and lost wages — then apply your state’s comparative-negligence rule, its damage caps, and its filing deadline. The result is a range, with every step shown and cited.

Child Support

Every state sets child support with a published guideline formula — income shares, percentage of income, or the Melson formula. Pick your state to run its own math step by step, see which figures the statute actually uses, and open the official worksheet it comes from.

Property Tax Appeal

Work out how far your assessment sits above comparable sales, what a reduction would save at your local rate, and what each of the three routes to it costs — filing yourself, a flat-fee service, or a contingency service. Every county deadline is cited to the authority that sets it.

Five wings, one hub

Injury Settlement Math

How injury claims are valued on paper: the multiplier and per-diem methods described in published consumer-legal literature, plus your state’s comparative-negligence rule, damage caps, and filing deadline. Every estimate is a range, every state figure cites the statute it comes from.

Child Support Guidelines

Every state computes child support from a published guideline formula — income shares, percentage of income, or Melson. These calculators run your state’s own math step by step and link the official worksheet or calculator it comes from. Courts retain discretion to deviate.

Alimony & Custody Schedules

A handful of states publish a spousal-support formula; most list statutory factors instead, and we show which is which rather than inventing a number. The custody planner builds standard schedules, counts overnights, and hands that percentage to your state’s support calculator.

Will Requirements by State

What each state’s probate code actually requires to execute a valid will: witness count, notarization and self-proving affidavits, whether handwritten wills are recognized, and where electronic wills are authorized. Every cell cites the statute. Requirements only — we never draft documents.

Property Tax Appeals

Assessment appeals run on published deadlines and published math. Estimate how far your assessment sits above comparable sales, calculate what a reduction saves at your local rate, and look up your county’s protest window, hearing body, and official filing portal.

Child Support

Every state sets child support with a published guideline formula — income shares, percentage of income, or the Melson formula. Pick your state to run its own math step by step, see which figures the statute actually uses, and open the official worksheet it comes from.

Pain & Suffering

Work out what the published multiplier and per-diem methods produce from your medical bills, projected treatment and lost wages — then apply your state’s comparative-negligence rule, its damage caps, and its filing deadline. The result is a range, with every step shown and cited.

Car Accident

Estimate a car accident claim the way published consumer-legal literature describes it: economic damages, a severity multiplier or a per-diem figure, then your state’s fault rule and any statutory cap. Outputs a range with the arithmetic shown and the statute behind each adjustment cited.

Case File

A ten-point check of how complete your documentation is — the records, bills, photographs, timeline and deadline that any conversation about a claim starts from. It scores the paperwork, never the claim, and prints as a cover sheet you can take to a consultation.

Alimony

Only a handful of states publish a formula for spousal support. Some cap the amount without publishing a formula, and most publish a factor checklist and no number at all. Pick your state to see which of the three it is, run whatever math it does publish, and read the factors a court actually weighs.

Custody Planner

Build a parenting schedule from the standard rotations courts see most — 2-2-3, 2-2-5-5, 3-4-4-3, week-on-week-off, or every other weekend — then count the overnights exactly. The percentage carries straight into your state’s child support calculator, and the calendar exports and prints.

Will Requirements

What each state’s probate code requires to execute a valid will: the minimum age, how many witnesses must sign, whether a notary is needed, whether handwritten wills count, and where electronic wills are authorised. Sortable, every cell cited to the statute and dated when it was read.

Electronic Wills

Which states authorise electronic wills, which have passed an act that has not started yet, and which authorise nothing. The distinction matters: a post-dated statute is not law today, and signing under one before its operative date relies on a rule that has not begun.

Will vs Trust

Seven questions covering the factors estate planners commonly treat as reasons to look past a simple will — property in two states, a business, incapacity planning, contest exposure. It shows its scoring as you answer and cites your state’s small-estate threshold rather than hiding the reasoning.

Property Tax Appeal

Work out how far your assessment sits above comparable sales, what a reduction would save at your local rate, and what each of the three routes to it costs — filing yourself, a flat-fee service, or a contingency service. Every county deadline is cited to the authority that sets it.

Appeal Letter

Build a one-page notice of protest from your parcel number, the assessed value, the value you believe is correct, and your comparable sales. It states facts and requests a review — it makes no legal argument, and nothing you type leaves your browser.

What happens between your inputs and a number

Most legal calculators show you a figure and ask you to take the arithmetic on faith. Here is the whole path, in four steps.

  1. You enter the facts you already have

    Medical bills and days of treatment. Two incomes and the number of children. Overnights on a calendar. An assessed value and a sale down the street. Ordinary figures, typed into your own browser and sent nowhere.

  2. Your state's published formula runs on them

    Not our formula — the one the legislature, the judiciary, the child support agency, or the county already publishes. Income shares, percentage of income, or Melson. The comparative-negligence rule and the cap that applies where you live. Each step is shown, so you can follow the arithmetic instead of trusting it.

  3. It returns a range, not an answer

    Every estimate comes back low to high, because the published methods carry real uncertainty and one number would hide it. A range describes what a formula produces. It is not a prediction of a settlement, an award, or a court order — courts keep their discretion, and insurers use software this page cannot see.

  4. And it hands you the source of record

    Every result carries the statute, guideline, or county notice it came from, the date a human opened that document, and a link to go read it. Where the jurisdiction publishes its own calculator or worksheet, we point you at it and tell you to compare. When a figure passes its review date the page says so; when we cannot open a source, we publish nothing for that jurisdiction.

Verified, dated, cited

Every figure is transcribed from the legislature, court system, child support agency, or county assessor that published it, and stamped with the date we read it. See every source →
