Child Support Paid/Contributed
PLEASE NOTE:  An important distinction exists between child support paid and child support contributed. The State of Arizona’s public policy recognizes that all children have a right to be supported by their parents. When a parent has multiple children living in different households, that parent’s income is distributed between all the children, which reduces the amount available to each child individually.

Paid
Arizona Child Support Guidelines Section 6.B.

Enter the total amount of court-ordered child support that you and/or the other parent (if you know this information) pay for children of other relationships, if actually being paid. This amount is deducted from the gross income of the parent paying that child support. Court-ordered arrearage payments are not included.

Child Support Paid is:

• an amount that has been ordered by a court; and
• an amount a parent pays to support a child for whom they are not the primary custodial parent; and
• actually being paid.

Contributed
Arizona Child Support Guidelines Section 6.C.

Enter the amount that you and/or the other party (if you know this information) contribute for children of other relationships for whom you are the custodial parent (the child lives in the same household with you). This amount is deducted from the gross income of the parent contributing that support. The adjustment amount you may request is determined by a Simplified Application of the Guidelines (example provided below).

Example:  A parent having gross monthly income of $2,000 is also the parent of a child who is not the subject of the child support case before the court and for whom no child support order exists. To use the Simplified Application of the Guidelines, locate $2,000 in the Combined Adjusted Gross Income column of the Schedule of Basic Support Obligations. Select the amount in the column for one child, $420.  Enter this amount in the calculator.

Child Support Contributed is:

• an amount of financial support for children of other relationships that has not been ordered by a court; and
• an amount a parent spends for children of other relationships for whom they are the primary custodial parent. For example, a parent remarries and has a child with the new spouse. That parent must support that child even though there no court order requires him or her to do so.

Support of Other Children
Arizona Child Support Guidelines Section 6.D.

You may ask the court to consider the financial obligation you have to support other natural or adopted children for whom there is no court order requiring you to pay support.  If you choose to do this, the adjustment amount you may request is determined by a simplified application of the guidelines (example provided below).

Example:  A parent having gross monthly income of $2,000 supports a natural or adopted minor child who is not the subject of the child support case before the court and for whom no child support order exists. To use the Simplified Application of the Guidelines, locate $2,000 in the Combined Adjusted Gross Income column of the Schedule of Basic Support Obligations. Select the amount in the column for one child, $420.  Enter this amount in the calculator.

Medical Insurance Costs for Child(ren)
Arizona Child Support Guidelines Section 9.A.

Enter the monthly dollar amount of the portion of the medical insurance cost that is or will be paid for medical insurance for the child(ren) included in this court order. The court is required to consider the cost for medical insurance, and may consider the cost of dental and vision insurance.

To determine the children’s portion of medical (dental/vision) insurance, follow this example.

Example:  Through an employment‑related insurance plan, a parent provides medical insurance that covers the parent, one child who is the subject of the child support case and two other children. Under the plan, the cost of an employee's individual insurance coverage would be $50. This parent instead pays a total of $170 for the "family option" that provides coverage for the employee and any number of dependents. Calculate the adjustment for medical insurance as follows: Subtract the $50 cost of individual coverage from the $170 paid for the "family option" to find the cost of dependent coverage. The $120 remainder then is divided by three ‑‑ the number of covered dependents. The resulting $40 is added to the Basic Child Support Obligation as the cost of medical insurance coverage for the one child.

Back

Childcare Costs
Arizona Child Support Guidelines Section 9.B.1.

Enter the amount of childcare costs that are actually paid or would be appropriate for the parents' financial abilities.   The calculator will automatically make an adjustment for the federal childcare tax credit for the dependent children at certain income levels (custodial parent only). This credit is available only to the custodial parent under federal tax law and it is accordingly available only to the custodial parent in the child support calculation.

Back

Extra Education Costs
Arizona Child Support Guidelines Section 9.B.2.

Enter the monthly dollar amount for reasonable and necessary expenses for private or special schools or necessary expenses to meet particular education needs of a child.  Both parents must agree to these expenses or the court must order them.

Number of Parenting Time Days Per Year
Arizona Child Support Guidelines Section 11

Please Note:  If you share equal custody with the other parent, please do not enter anything in this section.  Instead, see Guidelines Section 12.

Enter the number of parenting time (visitation) days indicated in a court order or parenting plan or by the expectations or historical practice of the parents (see below).  The calculator will automatically calculate the corresponding parenting time adjustment that the noncustodial parent may receive for parenting time that is or is expected to be exercised by that parent.

1. Each block of time begins and ends when the noncustodial parent receives or returns the child from the custodial parent or from a third party with whom the custodial parent left the child.   Third party includes, for example, a school or childcare provider.
2. Count 1 day of parenting time for each 24 hours within any block of time. To the extent there is a period of less than 24 hours remaining in the block of time, after all 24-hour days are counted or for any block of time which is in total less than 24 hours in duration:

1. A period of 12 hours or more counts as one day.
2. A period of 6 to 11 hours counts as a half-day.
3. A period of 3 to 5 hours counts as a quarter-day.
4. Periods of less than 3 hours may count as a quarter-day if, during those hours, the noncustodial parent pays for routine expenses of the child, such as meals.

Example One: Noncustodial parent receives the child at 9:00 p.m. on Thursday evening and brings the child to school at 8:00 a.m. on Monday morning, from which custodial parent picks up the child at 3:00 p.m. on Monday.

1. 9:00 p.m. Thursday to 9:00 p.m. Sunday is 3 days.
2. 9:00 p.m. Sunday to 8:00 a.m. Monday is 11 hours, which equals a half day.
3. Total is 3 ½ days.

Example Two:  Noncustodial parent picks the child up from school at 3:00 p.m. Friday and returns the child to school at 8:00 a.m. on Monday.

1. 3:00 p.m. Friday to 3:00 p.m. Sunday is 2 days.
2. 3:00 p.m. Sunday to 8:00 a.m. Monday is 17 hours, which equals 1 day.
3. Total is 3 days.

Example Three:  Noncustodial parent picks up child from soccer at noon on Saturday, and returns the child to custodial parent at 9:00 p.m. on Sunday.

1. Noon Saturday to noon Sunday is 1 day.
2. Noon Sunday to 9:00 p.m. Sunday is 9 hours, which equals ½ day.
3. Total is 1 ½ days.
