Frequently Asked Questions
Are these calculators accurate?
Our calculators use the same formulas that attorneys and courts use as starting points. However, legal outcomes depend on many case-specific factors. Use our results as informed estimates, not guarantees.
Do I need to create an account?
No. All calculators are completely free and require no sign-up, email, or personal information of any kind.
Which states do the calculators cover?
Our calculators cover all 50 US states. For child support, we use the Income Shares Model (41 states). For alimony and DUI, we provide state-category options since laws vary significantly.
Should I still hire an attorney?
Yes — always. Our calculators are educational tools to help you understand your situation, not substitutes for legal advice. Use them to be better prepared when you speak with an attorney.
