Following a divorce, when children factor in, child support becomes one of the biggest ongoing expenses parents face. These court-ordered payments provide for the continued care and maintenance of your children. They cover everything from everyday costs like food and shelter, to medical care and even education. Because they play such a vital role, there’s a child support formula to establish payment amounts.

In California, the child support formula takes into account a wide array of financial factors. This calculation considers things like the income of each parent, the amount of time each parent spends with the child(ren) in question, potential tax deductions, level of need, and more.

California state law requires the court to follow these guidelines in order to provide uniformity from case to case. 

Calculate Your Own Responsibility

To start your journey through the child support formula, you need a variety of information about income, taxes, and finances.

  • You need your most recent tax returns, paycheck stubs, and tax forms, like W-2s or 1099s.
  • any paperwork that documents disability or unemployment benefits,
  • health insurance premiums,
  • child care costs,
  • mandatory fees like union dues or retirement contributions,
  • job related expenses.
  • If you have child support payments for other children,
  • spousal support payments, or similar costs, collect those.

In addition to your personal information, you also need to enter the same data for the child’s other parent.

It may help to familiarize yourself with the child support formula ahead of time. That way you know what to collect and have ready when you plug in the numbers.


Breaking Down The Child Support Formula

In California, there is an actual mathematical child support formula. It looks remarkably similar to a problem from high school algebra:

CS = K [HN – (H%) (TN)]

Here’s What Each Piece Means:

  • CS: CS is the child support amount. Just like back in the day, this is the ultimate sum we’re trying to figure out. Think of it as “X equals” if that helps, and X, in this case, represents the payment amount.
  • K: K is the total of both parents’ income. Child support comes out of this total. Income includes monthly salary before taxes and money from other sources like bonuses or commissions. This also accounts for how much the parents earn and the amount of time the highest earner spends with the kids.
  • HN: HN means high net, which is total disposable income for the higher earning parent.
  • H%: H% represents the percentage of time the higher earning parent spends as the primary guardian responsible for the child. This depends on the parenting plan, custody arrangement, and visitation. For example, if this parent has the kids 25% of the time, H% equals 25.
  • TN: TN is the combined net monthly total of disposable income between the two parents.

While the child support formula looks complicated, and it is, this all serves to nail down the specific amount.

In a general sense, the larger the income gap between the two parents, and the less time the higher earning parent is responsible for the kids, the more child support that parent owes.
