Michigan Child Support Calculator
Michigan's current support workflow runs through the official public MiChildSupport calculator, the 2025 Michigan Child Support Formula materials, and the Friend of the Court review process. Use this page to prepare the right inputs before you rely on the official Michigan tool.
Before You Open the Official Michigan Tool
The public Michigan calculator works better when you organize the same inputs that drive a Friend of the Court support review.
Core inputs
- Current income information for both parents.
- Number of children and current overnights for each parent.
- Current health-care and child-care costs tied to the children.
Facts worth checking first
- Whether the case turns on updated wages, self-employment, or imputed income.
- Whether an existing order is being reviewed or a first support amount is being set.
- Whether the case may later need a deviation or modification analysis.

Official public tool
MDHHS currently makes the MiChildSupport Calculator available to the public, not just program staff.
2025 formula materials
Michigan Courts currently publishes the 2025 manual and supplement that support the current formula baseline.
Not a final order by itself
MDHHS currently states that the public calculator amount is not itself a support recommendation or a court order.
How Michigan child support is structured
- Start with current income and parenting facts. Michigan's formula work depends on the parties' current financial information and the number of overnights with each child.
- Run the Michigan Child Support Formula. The official public calculator and the 2025 formula materials are built around that same statutory formula framework.
- Separate estimates from orders. The public tool helps with calculation, but actual recommendations and orders still move through the Friend of the Court and court process.
- Check review and modification issues next. If an order already exists, review timing and modification thresholds matter just as much as the raw formula output.
Intent check
Need a Michigan alimony calculator or Michigan spousal-support overview instead? Use the Michigan spousal support page, because Michigan treats spousal support through separate statutes and orders rather than the child support formula.
Use the Official Michigan Tool With the Current Formula Materials Beside You
The cleaner your income, overnight, child-care, and health-care inputs are, the more useful the public MiChildSupport result becomes.
