Disclaimer: Please remember that these calculators are for informational and educational purposes only.

Each state has it’s own statutory guidelines that judges use to determine the amount of monthly child support paid by the non-custodial parent. More info here.

The amount of child support a court will order for any particular case may be different from the amount estimated by the calculator. The calculator is giving an estimated average of child support based on previous cases, and external resources. However, you should always check your actual court order before making a decision.

For the most part, these calculators assume that all of the children at issue will primarily live with one parent. They are not intended to estimate child support for joint physical custody or split custody arrangements. For resources on how to reduce stress as a single parent, check out this blog post.

These calculators do not take into account any possible adjustments for children who are not subject to the custody order, but who are living with one of the parents. Finally, these calculators may be based on older or outdated state guidelines or calculations and may not take into consideration state or federal tax implications on income. Make sure to check with your state's guidelines to know what the latest updates are.
