How to use this tool?
This calculator estimates monthly child support under simplified California guidelines. Follow these steps:
- Enter Parent 1's Monthly Gross Income – Input a non-negative dollar amount (e.g., 5000).
- Enter Parent 2's Monthly Gross Income – Input a non-negative dollar amount (e.g., 3000).
- Enter Parent 1's Timeshare Percentage – The percentage of time the child spends with Parent 1 (0–100). Parent 2's timeshare is automatically calculated as 100% minus this value.
- Enter Number of Other Children – Other children each parent supports (not from this relationship). Use a non-negative integer (e.g., 0).
- Enter Additional Expenses – Monthly costs like childcare or health insurance (non-negative dollar amount, e.g., 200).
- Click "Calculate" – The estimated support amount appears below, along with a formula breakdown.
Note: All monetary inputs are in US dollars. Timeshare must be between 0 and 100. The calculator uses a simplified 25% guideline for one child, with adjustments for other children and timeshare.
