Choose your state

Start with the state where you expect to file.

Support formulas, filing fees, and spousal-support rules change at state lines. After choosing a state, use its county pages to check local filing details and court contacts.

Why location changes the math

There is no single U.S. formula for divorce costs or support.

The numbers people usually look for—filing fees, child support, alimony, and total cost—depend on state law, the local court, and the facts of the case. These are the differences that matter most.

01

Child support formulas

California uses both parents’ net disposable income and parenting time. New York starts with combined CSSA income. Texas generally applies a percentage to the paying parent’s net resources. The same family numbers can lead to a different guideline in each state.

02

Alimony and maintenance

New York has income formulas and an advisory duration schedule. Texas limits court-ordered maintenance to specific eligibility paths and a statutory ceiling. California has no statewide formula for final spousal support; courts consider the §4320 factors.

03

Court filing fees

A California divorce petition usually costs $435–$450. New York says an uncontested divorce costs at least $335 in court fees. Texas starts with $350 in required district-court fees, with some child-related local fees added. Service and other expenses are extra.

04

Property and debt rules

California generally divides the community estate equally. Texas uses a just-and-right division of community property. New York uses equitable distribution. In every state, tracing separate property or valuing a home, pension, or business can add work and expense.

05

How much the spouses agree

The court filing fee does not show how much legal work a case may need. Disputes over parenting, income, property, or missing records can lead to discovery, temporary hearings, mediation, expert work, and trial preparation.

06

County rules and practical details

A statewide child-support formula stays the same, but counties may publish different filing instructions, local surcharges, service resources, and temporary-support practices. Always confirm the live fee schedule and filing method with the court handling your case.

Treat the result as a starting point, not an answer from a judge.

Use the calculators to organize the numbers you know, compare a few realistic scenarios, and make a list of questions before you pay for professional time. Every adjustable assumption remains visible.

Pause before relying on the result if income is disputed, records are incomplete, a business or pension needs valuation, safety is an issue, or the court may depart from a guideline. Those questions need evidence and advice tailored to the case.

  1. 01

    Recent income, parenting-time, court-fee, and professional-cost information will give you a better starting point.

  3. 03

    Check what moved the result

    Review the percentage, cap, duration range, or cost item, then change one uncertain input at a time.

    Use the linked guide and official sources before relying on the estimate for a financial or legal decision.

What a divorce may cost

The filing fee is only one part of the bill.

Court fees are usually the easiest costs to identify. Legal work, disputed issues, and the steps needed after judgment can create a much wider range. Listing those costs separately gives you a budget you can update when real quotes come in.

Where the numbers come from

The source links are part of the estimate.

For legal rules, we start with statutes, state court materials, support agencies, official forms, fee schedules, and county clerks. Suggested attorney or mediation costs stay editable because they are budget assumptions, not statewide averages. Every calculator shows its sources, effective dates, last review date, and important limits.

The current California, New York, and Texas material has not been reviewed by a licensed attorney. The calculators are educational estimates and the linked official material remains the controlling source.

Questions before you start

What to expect from the result

If you face a filing deadline, a safety concern, or a decision that could change your legal rights, check the current court rules and speak with a qualified professional in your state.

Which states have divorce calculators on this site?

California, New York, and Texas currently have calculators. Each state has a divorce cost estimator, a child support calculator, an alimony or maintenance calculator, step-by-step guides, county information, and links to the official rules we used.

Do I need to pay or create an account?

No. You can use every calculator and see the complete on-screen result without paying, signing in, or entering contact information. The optional detailed PDF request asks for your name, email, phone number, ZIP code, and consent to be contacted.

Can I use a calculator result in court?

No. These are educational tools, not court-certified calculations, legal advice, or evidence. A calculator cannot verify your income figures, resolve disputed facts, or predict whether a judge will depart from a guideline. Check court-filing numbers with your court, lawyer, or family-law facilitator before relying on them.

When were the state rules last checked?

The California, New York, and Texas materials were last checked on August 12, 2026. Each state page also shows its review date, the effective date of the rule set, and links to the statutes, court pages, or fee schedules behind the calculation.

Why does each state need a different calculator?

Because the legal starting points are different. California child support uses both parents’ net disposable income and parenting time. New York combines the parents’ adjusted CSSA income. Texas generally applies a percentage to the paying parent’s net resources. Filing fees and spousal-support rules also vary, so one national formula would give a misleading result.

What is included in a divorce cost estimate?

The estimator separates court filing fees, service, attorney time, mediation, other professional help, and follow-through costs such as deeds or retirement orders. You can replace the suggested amounts with real quotes. The result is a budget to work from, not a quote or a prediction of your final bill.

What information should I have ready?

Start with recent income figures for both spouses, the number of children, a realistic parenting schedule, and the county where the case may be filed. For a cost estimate, current quotes for legal help, mediation, service, or specialist work are more useful than the suggested amounts. You can still begin if some figures are uncertain and compare more than one scenario.
