Questions We Get Asked
Are these legal tools free?
Yes. Each calculator runs entirely in your browser, costs nothing, and requires no sign-up.
Do the tools give legal advice?
No. Each tool produces a general estimate from the numbers you provide. It cannot account for the facts of your case, so it is not a replacement for advice from a licensed attorney.
Where do the numbers come from?
You provide the inputs, such as wages, medical bills, or attorney rates. Each tool documents its formula and assumptions on the page.
How accurate are the estimates?
They are rough planning estimates. Real outcomes depend on your state, the facts, and the parties involved, so treat the results as orientation only.
Important: This page is published for general research and education. It is not legal advice, and it does not create an attorney-client relationship. Statutes are amended often and may contain exceptions. Because outcomes depend on your own facts, speak with a licensed attorney in your jurisdiction about your situation. See the full disclaimer.
