Formula Used

Child Support Calculation Formula

The basic formula for child support is:

Child Support = (Gross Income × Percentage) ÷ Number of Children

The percentage used depends on your state's guidelines. For example, in many states, the standard percentage is 17% of the parent's gross income.

This calculator uses the standard percentage for your selected state. If no state is selected, it uses a default percentage of 17%.

Worked Example

Let's say you have two children and your gross monthly income is $3,000. Using the standard 17% percentage:

  1. Calculate 17% of $3,000: $3,000 × 0.17 = $510
  2. Divide by the number of children: $510 ÷ 2 = $255 per child

So your total monthly child support payment would be $510, with $255 going to each child.

Additional Considerations

While this calculator provides a good estimate, actual child support amounts may vary based on:

  • Your state's specific child support guidelines
  • Whether you have custody or visitation rights
  • Any deductions for health insurance, daycare, or other expenses
  • Special circumstances like disabilities or medical needs

Important Note

This calculator provides an estimate only. For official child support calculations, consult your state's child support agency or a qualified legal professional.
