All 50 US states. Most calculators let you pick your state and apply its own formula, limits or fee schedule; a few use national ranges with state rules for the largest states. Data is reviewed regularly and updated when state laws change. Some calculators also note county-level variations where they significantly affect results.

Child support is calculated using the official formula for your state. Most states use the Income Shares model, which combines both parents' incomes and divides responsibility proportionally. Texas and several others use the Percentage of Income model: 20% of net resources for one child, 25% for two, 30% for three, up to 40% for five or more. Delaware, Hawaii, and Montana use the Melson Formula. The child support calculator applies the correct model automatically.

A first-offense DUI typically costs between $10,000 and $25,000 over three years when all costs are included. This covers court fines ($500 to $2,500 depending on state), attorney fees ($1,500 to $5,000), mandatory DUI school ($300 to $1,500), license reinstatement fees ($100 to $500), ignition interlock device costs if required ($950 to $1,400 per year), and auto insurance rate increases of $1,500 to $3,500 per year for three or more years.

The personal injury calculator provides an estimate based on your medical bills, lost wages, and injury severity. Most settlements use the multiplier method: total economic damages multiplied by 1.5 to 5 depending on how severe and permanent the injuries are. The result is adjusted for your percentage of fault using your state's comparative negligence rules. The calculator gives a low, mid, and high estimate range.

State-specific data is reviewed several times a year and updated when new laws or fee schedules take effect, including the January and July dates when many states change their rules. DUI fine schedules, child support formulas, and personal injury statute of limitations data are cross-referenced against official state statutes and government sources. Each calculator page shows the date it was last reviewed.
