If you are a parent in California going through a divorce, or you were never married to your child’s other parent, you will likely face important questions about child support. Will you receive payments, or will you be required to pay? How much will the support amount be? Under what circumstances can it change or come to an end?
In California, the parent who earns more typically pays child support, but this is not always the case. Under California law, both parents have an equal, mutual responsibility to support their children according to their ability. When the parents are separated or divorced, one usually pays child support. The law assumes that the other parent meets their share by contributing “a significant portion of available resources” to pay directly for the child’s needs.
Like every state, California follows established guidelines designed to give both parents and judges a consistent framework for determining appropriate child support. As a general rule, the greater the difference between the parents’ incomes and the less time the higher-earning parent spends with the children, the more child support that parent will owe. However, the rules and formulas used to calculate support can be complex. While the state offers online calculators and helpful resources, it is important to first understand how the guidelines work.
The Formula
The formula for calculating child support can be found in Family Code § 4055. It is CS = K[HN – (H%)(TN)]. The components of the formula are as follows:
CS = child support amount.
K = amount of both parents’ income to be allocated for child support
HN = high earner’s net monthly disposable income.
H% = approximate percentage of time that the high earner has or will have primary physical responsibility for the children compared to the other parent
TN = total net monthly disposable income of both parties.
Child Support Example
Parents:
- Parent A (higher earner): $6,000/month net income
- Parent B: $3,000/month net income
- Combined income (TN): $9,000/month
Custody:
- Parent A has the child 30% of the time.
- Parent B has the child 70% of the time.
Step-by-Step Calculation
- HN (higher earner net) = $6,000
- H% (time share) = 30% → 0.30
- TN (total net income) = $9,000
- K (approximate factor): For one child, this is often around 0.20–0.25 (varies slightly)
We will use 0.22 for this example
CS = 0.22 × [6000 – (0.30 × 9000)]
CS = 0.22 × [6000 – 2700]
CS = 0.22 × 3300
CS = $726/month
Parent A would pay approximately $726 per month in child support to Parent B.
What Counts as Income When Calculating Child Support?
In California, child support calculations begin by determining each parent’s monthly gross income. This includes a wide range of earnings and financial benefits:
- Wages, salaries, commissions, bonuses, severance pay, and self-employment income
- Business income and rental property income
- Pensions and annuities
- Investment earnings, including interest and dividends
- Certain benefits, such as workers’ compensation, disability, Social Security, unemployment, and veterans’ benefits (if not need-based)
- Military housing and food allowances
- Spousal support received from a prior relationship (but not child support for other children)
From Gross Income to Net Disposable Income
Because California’s formula is based on net disposable income, certain expenses are deducted from gross income. These may include the following:
- Actual state and federal income taxes (not just withholding), plus Social Security and Medicare
- Mandatory payroll deductions (such as union dues, retirement contributions, or state disability insurance)
- Health insurance premiums for the parent and children
- Necessary job-related expenses (subject to court approval)
- Child support or spousal support paid for obligations outside the current case
- Approved expenses related to “extreme financial hardship,” such as high medical costs or uninsured catastrophic losses
When Can Child Support Be Modified?
To request a modification, you generally must show a “material change in circumstances.” Common examples include:
- A significant increase or decrease in either parent’s income.
- Job loss or change in employment.
- Changes in custody or parenting time.
- New child-related expenses (like childcare, education, or medical needs).
- One parent becoming incarcerated or disabled.
- Changes in tax filing status or financial obligations.
FAQs
Q: Is overtime or bonus pay included?
A: Yes. Overtime, commissions, and bonuses are typically included, especially if they are consistent or expected. Courts may average these earnings over time to reach a fair monthly figure.
Q: Is there a minimum or maximum child support amount?
A: There’s no fixed minimum or cap. The amount is based on the guideline formula, but courts may deviate in special circumstances, such as very high incomes or unique child needs.
Q: Does self-employment income count differently?
A: Yes. Self-employment income is calculated as gross receipts minus legitimate business expenses. However, courts may closely review deductions to prevent underreporting of income.
Q: Can a parent hide income to reduce child support?
A: Not legally. Courts can impute income if they believe a parent is underreporting earnings or is intentionally unemployed or underemployed. Financial records and lifestyle evidence may be used to determine actual income.
Q: Can parents agree to a different amount than the guideline?
A: Yes, but the agreement must be approved by the court. Judges will ensure the arrangement is in the child’s best interest and that both parents understand their rights.
Q: Do employee perks or benefits count as income?
A: Sometimes. If benefits such as a company car or housing significantly reduce living expenses, a judge may include their value as part of income.
