Why this is the magnet
Same statewide method. County where you file.
Arizona does not invent a different child support formula per county. Pinal County Superior Court applies the statewide income-shares Child Support Guidelines. Spousal maintenance uses the statewide Spousal Maintenance Guidelines under A.R.S. § 25-319. That accuracy is the product.

If you want a person
Decide what help you want.
Many people only need the calculator. If you want a conversation, a coordinator responds on a business day. Legal advice belongs with an independent attorney.
MyDivorceCalc coordinator
A MyDivorceCalc coordinator can discuss questions and next-step logistics, but cannot give legal advice. Responds within one business day.
Independent family law attorney
Legal advice belongs here. If you choose to consult an attorney, bring your estimate — the inputs and assumptions make the first conversation faster. MyDivorceCalc does not recommend or rank attorneys.
Using this site, running an estimate, or submitting a form does not create an attorney-client relationship.
Questions
Useful context before you begin.
The estimate is a planning tool, not a prediction of what a judge will order.
Read the methodology disclaimerIs this the official Arizona child support calculator?+
No. The Arizona Judicial Branch publishes the official calculator and worksheet. MyDivorceCalc is a free educational calculator using the same statewide income-shares Child Support Guidelines so you can see the order of magnitude before you use the court tool or talk with counsel.
Is the method different in Pinal County vs other Arizona counties?+
No. Arizona child support uses one statewide income-shares schedule under A.R.S. § 25-320 and the Arizona Child Support Guidelines. Pinal County Superior Court applies those same guidelines. The county is where the case is filed and heard — not a separate formula.
Do you have a spousal maintenance / alimony calculator?+
Yes — an educational estimator. Arizona uses statewide Spousal Maintenance Guidelines under A.R.S. § 25-319. We return published duration ranges and an illustrative monthly band, and we link the official statewide Spousal Maintenance Calculator for filing-quality figures.
Which counties are open?+
Pinal County and Maricopa County are both open. Arizona uses one statewide income-shares schedule — the county is where the case is filed and heard, not a separate formula.
Do I have to give my contact information to see a number?+
No. The estimate is shown after you enter the calculator inputs. Contact information is optional if you want a coordinator to follow up.
Is this legal advice?+
No. MyDivorceCalc is not a law firm. Using the site does not create an attorney-client relationship. Only a court can set child support or spousal maintenance. If you want legal advice, an independent Arizona-licensed family law attorney is the right person.
