To use the child support calculator, select or enter the appropriate information next to each statement.

When you have completed the form, click on the calculate button to get an estimate of the amount of child support that the non-custodial parent will have to pay to the custodial parent in Michigan.

Disclaimer: Please remember that these calculators are for informational and educational purposes only. The amount of child support a court will order for any particular case may be different from the amount estimated by the calculator.

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.

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 Finally, these calculators may be based on older or outdated state guidelines or calculations and may not take into consideration state or federal tax implications on income.

These and many other factors can affect a child support order entered by a court.
