What Is the Average Child Support Payment in California?

Child support is necessary for the raising and care of a child, along with providing for their basic needs, after their parents are separated. Both parents have an obligation to financially provide for their child, and support payments ensure that this happens. Parents who are starting a child support determination case often wonder, “What is the average child support payment in California?”

Child support payments can vary depending on circumstances. Because California uses a formula to decide child support payment amounts, it is useful to understand the factors that influence its calculations.

Average Child Support Payment In California

Hire a Child Support Lawyer

Child support agreements may be part of a divorce case, a child custody case between unmarried parents, or a paternity case. Whether parents decide the amount for support payments outside of court or not, the court must approve it. When you hire a child support lawyer, you gain an ally who can help you navigate a negotiation or court decision and can make the process much easier.

Parents Deciding Child Support Outside of Court

Similar to other family court orders, parents can negotiate a child support amount outside of court. They can then submit this agreement to the court for approval. This enables parents to have more control over how child support is assigned.

However, because it is a court order that affects children, the court must find that it is in the child’s interests. Parents who create an agreement must still know the amount of support that would be assigned based on the state formula. Because the support agreement must be in the child’s interests, parents must explain why deviations have been made from the formula. An attorney is essential to creating an effective and fair agreement.

How California Determines Child Support

Child support relies mostly on the income of each parent, the amount of time that the primary custodial parent spends with the child, and the number of children that each parent needs to support.

After decades of using the old method, California updated how child support payments were calculated, effective September 1st, 2024. The child support formula in California is now CS = K [HN – (H%) (TN)]. The components of the formula are:

  • K is the amount of parental income that is set aside for child support. This follows its own formula based on the combined disposable income of both parents and the time that parents have custody of a child.
  • HN is the net monthly disposable income of the higher-earning parent.
  • H% is the percentage of time that the higher-earning parent spends with custody of their children.
  • TN is the total net monthly disposable income.

The amount of child support for one child is determined based on these factors, but it can be more complicated if parents have different parenting time percentages with different children.

The court or parents can also alter the guidelines if the child has extraordinary needs, such as high medical costs, which are not considered in the basic costs of raising a child.

If the final amount is a positive number, then the parent who earns a higher amount pays the amount to the lower-earning spouse. If the amount is negative, the lower-earning spouse pays the absolute value of the amount as child support payments to the higher-earning spouse.

Determining Each Parent’s Income

To determine each parent’s net disposable income, deductions are made from each parent’s annual gross income. Deductions are made for:

  • State and federal income tax liability
  • Deductions attributed to retirement or disability benefits
  • Mandatory union dues and retirement benefits
  • Health insurance or health plan premiums for the parent and any children
  • Child or spousal support payments that are already being paid
  • Job-related expenses
  • Hardship deductions

When calculating a hardship deduction, it is applied to the annual gross income, not to the actual child support payment. Hardship deductions can be made for:

  • Extraordinary health expenses
  • Minimum basic living expenses for natural or adopted children who reside with the parent

The maximum hardship deduction allowed for children living with the parent cannot exceed the amount paid in support to any child not living with the parent. Once each parent’s net disposable income is determined, it can be divided by 12 to determine the monthly disposable income. From there, the value of K can be determined based on the sum of the parents’ net disposable incomes.

The Importance of the New K-Factor

With the addition of the K-factor to the new method for calculating child support in California, the courts can now take into account how much time each parent spends with their children and adjust child support payments accordingly. This change means that low-earning parents who have their children almost exclusively can receive higher child support payments.

Conversely, if a higher-earning parent cares for their children more often, they could receive payments from the lower-earning parent. Calculated as a percentage of time each parent spends with their children, the K-factor also takes into consideration several different factors, specifically:

  • Parenting time
  • Income of both parents
  • Additional expenses unique to each child, such as healthcare, education, or childcare costs

The addition of the K-factor was important for many reasons. It allows for a fairer system for determining child support, encourages parents to share the time requirements of parenting, provides a more transparent calculation to reduce conflict between parents, and meets each child’s optimal needs.

Changes for Multiple Children

If more than one child is being considered when calculating child support payments, the value of CS is multiplied by a predetermined multiplier. For instance:

  • 2 children, the multiplier is 1.6
  • 3 children, the multiplier is 2
  • 4 children, the multiplier is 2.3
  • 5 children, the multiplier is 2.5
  • 6 children, the multiplier is 2.625
  • 7 children, the multiplier is 2.75
  • 8 children, the multiplier 2.813
  • 9 children, the multiplier is 2.844
  • 10 children, the multiplier is 2.86

These multipliers use a formula of diminishing rates when calculating support for more than one child. This is because it does not cost exactly double to raise two children compared with only one child.

Child Support Changes in 2026

The Senate Bill 343 does more than just make changes to how child support is calculated in California. Other key aspects of the bill include:

  • Parents who were incarcerated have their child support obligations suspended for 10 months after their release.
  • Low-income parents, specifically those earning less than $2,773.33 per month, can receive a reduction in their child support obligations.
  • When a family’s circumstances change, they have the right to have their child support order reviewed.
  • Instead of each parent equally sharing the cost of medical and child care, these expenses are now distributed based on each parent’s financial capacity.
  • Local child support agencies are required to make appropriate efforts to determine a parent’s actual income before making determinations based on their earning capacity.
  • The requirement that the court create an expedited support order requiring child support payments under the statewide guidelines has been repealed.

FAQs

Q: How Much Should a Father Pay for Child Support in California?

A: A father should pay what is ordered by the court in child support if he is ordered to pay support. Both parents, regardless of gender, have an obligation to financially support their child, and either parent could be required to provide that support to the other if they separate.

A parent with less custody, who therefore shoulders less of the costs of raising a child, often pays child support. A parent with a higher income may also pay child support.

Q: What Is the Minimum Child Support in California?

A: There is no set minimum for child support in California, as it should depend on the income of each parent and the number of children who require support. Child support payments for one child can change drastically based on many factors.

These factors include custody of a child, the income of each parent, and other unique circumstances. An attorney can help a parent determine what a fair amount of support is for their child.

Q: How Does California Calculate Child Support?

A: California law has a formula for calculating child support, which considers the difference between both parents’ monthly disposable income, how much parenting time each parent has, and the amount of each parent’s income that is allocated for child support.

The state child support law then multiplies the number obtained from the formula by a set number, depending on the number of children who need support. Each child support calculation should be unique based on these many factors.

Q: How Much Is Child Support in California for 50-50 Custody?

A: If parents have 50-50 custody of their child, child support is typically reliant on the difference in the parents’ income. The parent who has a higher net monthly disposable income could likely pay the other parent child support.

That way, both parents pay a proportional amount for their child’s care. Often, although parents have 50-50 custody, a perfect split is not always practical, so one parent may have slightly more parenting time. This should also affect child support calculations.
