Michigan Child Support Formula

Michigan's child support formula is a current manual-and-supplement workflow, not a loose private estimate. The official framework starts with the 2025 formula materials and the public MiChildSupport tool, then moves into court review if the case needs a different order.

How the Michigan formula is built

  1. 1Gather current income, parenting-time, health-care, and child-care facts for both parents.
  2. 2Apply the Michigan Child Support Formula using the 2025 manual and supplement baseline.
  3. 3Use the public MiChildSupport calculator to test the current formula result with the same basic framework.
  4. 4Separate formula output from the court-order process, because the public result is not itself a support order.
  5. 5If a different amount is requested, move into deviation analysis with a written record.

Required use rule

MCL 552.605 currently requires Michigan courts to apply the formula unless the court explains why using it would be unjust or inappropriate.

Current source set

Michigan Courts currently publishes both the 2025 manual and the 2025 supplement, so older formula summaries should be treated cautiously.

Calculator caution

MDHHS currently notes that the public MiChildSupport output is not itself a support recommendation or support order.
