Worked example: Alimony Child Support in Michigan

Example inputs

Below is a worked example for Michigan calculations using DocketMath’s alimony-child-support tool (jurisdiction-aware: US-MI). This walkthrough shows the mechanics and how changes to inputs affect the output.

Scenario (assumed facts for the example)

We’ll use a common “apples-to-apples” setup so you can compare how results react to input changes.

• Filing/judgment timing (relevant for retroactivity context, not the monthly amount itself)

  • Example dates: Judgment effective 01/15/2026
• Parties

  • Payor: John
  • Recipient: Mary
• Children

  • Number of children: 2
• Parenting time assumption

  • John: 30% overnights
  • Mary: 70% overnights
• Income assumptions

  • John gross annual income: $85,000
  • Mary gross annual income: $45,000
• DocketMath tool settings

  • Health insurance: $150/month (assume paid by John)
  • Retirement/special deductions: $0 (for simplicity in the example)
• Order framing

  • Start month for calculation: 02/2026
  • End month for calculation: 12/2026 (a 11-month sample window)

Input checklist

• Michigan jurisdiction selected (US-MI)
• Two children
• Parenting time split set at 30% / 70%
• Both incomes entered as annual amounts
• Health insurance monthly cost entered
• Calculation window selected (Feb 2026–Dec 2026)

Michigan time-period reference (general statute of limitations)

You may also see support issues tied to timing. Michigan’s general limitations period is 6 years under MCL § 767.24(1).

Michigan’s limitation note for this example:

• No claim-type-specific sub-rule was found, so the example uses the general/default 6-year period stated above.
• Source: https://www.michigan.gov

Reminder: This limitation note is about the timing/enforceability window for claims, not about how the tool computes the monthly support amount.

Example run

Now let’s run the scenario in DocketMath.

Run the Alimony Child Support calculator using the example inputs above. Review the breakdown for intermediate steps (segments, adjustments, or rate changes) so you can see how each input moves the output. Save the result for reference and compare it to your actual scenario.

Step 1: Open the tool and choose Michigan

Use:

• Primary CTA: alimony-child-support

Then confirm:

• Jurisdiction: **Michigan (US-MI)

Step 2: Enter the inputs

In DocketMath, enter:

Step 3: Review the output categories

DocketMath’s tool output is typically best reviewed in three layers:

1. **Child support component (monthly)
2. Alimony component (monthly) (if the tool includes alimony calculation outputs)
3. Total monthly support estimate (combined figure for the sample window)

Because this is a “worked example,” the important part isn’t only the headline number—it’s how each input tends to change the output.

Step 4: Results snapshot (what to look for)

After the run, focus on:

• Monthly totals for each component (child support and alimony, if present)
• Any month-by-month variation across the window (for example, if DocketMath reflects timing-based assumptions)
• The net effect of your parenting time and income differences

Practical “directional” expectations (for intuition as you review results):

• Higher payor income relative to recipient generally increases support.
• More parenting time for the payor generally reduces the payor’s net support burden.
• Health insurance add-ons often increase the monthly total (though exact treatment can vary by how the tool incorporates credits/additions).

Step 5: Timing reference (general SOL context)

If you’re tracking the enforceability window for unpaid amounts (not calculating the monthly number itself), Michigan’s general limitations period is:

• 6 years under **MCL § 767.24(1)

Sensitivity check

A worked example is most useful when you test “what if.” Below are three practical adjustments and the expected direction of change to look for in the DocketMath output.

To test sensitivity, change one high-impact input (like the rate, start date, or cap) and rerun the calculation. Compare the outputs side by side so you can see how small input shifts affect the result.

A. Change parenting time: 30% → 40%

Updated input: Payor overnights from 30% to 40% (increase by 10 percentage points).

Keep the rest the same:

• Payor income: $85,000
• Recipient income: $45,000
• Health insurance: $150/month

Expected direction to check:

• Child support typically decreases when the payor has more time.
• Total monthly support usually follows that direction, unless other model interactions or assumptions offset part of the change.

Checklist:

B. Change payor income: $85,000 → $95,000

Updated input: Payor annual income from $85,000 to $95,000 (+$10,000/year).

Keep the rest the same:

• Parenting time: 30% / 70%
• Recipient income: $45,000
• Health insurance: $150/month

Expected direction to check:

• Child support generally increases with higher payor income.
• Alimony estimates (if included in the tool) may also increase when the payor’s ability to pay relative to the recipient increases.

Checklist:

C. Change health insurance: $150/month → $250/month

Updated input: Health insurance monthly cost from $150 to $250 (+$100/month).

Keep the rest the same:

• Parenting time: 30% / 70%
• Payor income: $85,000
• Recipient income: $45,000

Expected direction to check:

• Total monthly support generally increases, because medical coverage is a tangible add-on affecting the monthly figure.
• The child support and/or alimony line items may shift depending on how the tool allocates or integrates insurance costs.

How to validate your numbers in DocketMath

To keep your testing clean and actionable:

• Run the baseline scenario first.
• Change one variable at a time.
• Compare:

  • Baseline vs. adjusted monthly child support
  • Baseline vs. adjusted monthly alimony (if present)
  • Baseline vs. adjusted total

Even two sensitivity runs usually reveal which inputs matter most for your specific set of assumptions.
