FAQs

1. What does this calculator estimate?

It estimates a payroll child support deduction using disposable income, a protected earnings rate, a withholding cap, prior withholding, and requested support amounts.

2. Why is disposable income important?

Disposable income is the pay remaining after key deductions. It becomes the base for cap checks and protected income calculations in the estimate.

3. What is protected income?

Protected income is the amount the employee keeps after payroll withholding. The calculator subtracts this protected portion before deciding the maximum deductible amount.

4. Why can the result be lower than requested support?

The result can be lower when the protected income rule or withholding cap blocks the full request. The remaining balance appears as a shortfall.

5. Does the order scenario change the cap rate?

Yes. The scenario selector loads a suggested cap based on common payroll assumptions. You can still override the cap percentage manually.

6. Can I include arrears and medical support?

Yes. Separate fields are included for current support, arrears, medical support, and an admin fee so payroll teams can model fuller withholding requests.

7. What does prior child support withheld mean?

It represents support already deducted during the same payroll cycle. The calculator subtracts that amount from the remaining cap before estimating a new deduction.

8. Should this result replace legal payroll guidance?

No. This is a planning and review tool. Payroll teams should always confirm actual withholding requirements against the order, agency rules, and local law.
