Child support in California is calculated based on a statewide formula called the “California Guideline Child Support Calculator.” It takes into account factors such as each parent’s income, the amount of custodial time each parent spends with the child(ren), and other deductions and expenses, such as deductible interest, property tax payments, mandatory pension/retirement contributions, hardship deductions, among others. There is also a “High Income Earner” exception to the California Guideline Child Support calculation application, which is a complicated analysis and application process. Consulting with an attorney with Family Law experience is always recommended.
