​Michigan Child Support Formula


As part of its responsibilities, the Friend of the Court Bureau developed a formula guideline for figuring child support obligation amounts. The law requires courts to use this formula when setting or changing child support obligations.
The child support formula is reviewed and changed periodically and its figures updated for economic changes. When these changes occur, the bureau issues a new Michigan Child Support Formula Manual. Michigan's guideline consists of the manual and its most current supplement or schedules.


Comments and Suggestions

The Friend of the Court Bureau collects public comment for the purpose of reviewing potential changes to the formula manual. We welcome anyone's input and always look to improve the manual. We encourage public comment to identify problems and to gather suggestions for improvement.
To appropriately document your issues, please make sure that all comments and suggestions are written, and: (1) clearly and concisely state your issues, (2) refer to specific manual provisions or language, (3) suggest specific changes or language changes, (4) include examples or comparisons on the effect of your proposed changes, and (5) include any related documentation or research.
