Inputs you will need
If you’re using DocketMath to estimate alimony and/or child support in Michigan (US-MI), you’ll want to gather a consistent set of inputs first. This checklist is built to help you collect the numbers DocketMath typically needs so your estimate reflects your situation as closely as possible.
Note: This content is informational and helps you prepare inputs for a calculation tool. It is not legal advice and does not guarantee any court outcome.
Alimony inputs (Michigan)
Check what you can document with pay stubs, benefit statements, or other records:
Practical tip: For irregular income (bonuses/commissions), DocketMath-style estimates are usually more reliable when you use a time window average instead of a single month.
Child support inputs (Michigan)
Gather these for each child and for each parent:
Timing and documentation inputs
Michigan estimates depend heavily on which months your figures represent. Before you run DocketMath, collect:
Statute reminder about repayment lookback (use as planning context)
Michigan has a general 6-year statute of limitations for certain claims relating to support obligations, referenced in MCL § 767.24(1).
- General SOL period used here: 6 years
- Clarity point: for purposes of this article, no claim-type-specific sub-rule was found, so the general/default period is described as the baseline.
- Citation: MCL § 767.24(1)

Where to find each input
Use the sources below to reduce back-and-forth while you fill in DocketMath.
Most inputs live in the case file, contracts, or docket entries. Dates usually come from the triggering event notice; rates and caps come from governing documents or statute; and amounts come from the ledger or judgment. Record the source for each value so the run is reproducible.
Income
- Pay stubs (last 2–3 months): gross wages, overtime, deductions (to the extent you need consistency for monthly figures)
- Employer statements / year-to-date summaries: bonus or commission patterns
- Tax returns (most recent): self-employment income averages and business-related income context
- Benefit statements: retirement/pension amounts and disability income
If you’re unsure what to enter: aim for consistent monthly figures. When income varies, averaging across recent months generally produces a more stable estimate than relying on one high- or low-income paycheck.
Parenting time / schedule
- Custody agreement or parenting plan (current or proposed)
- Your calendar totals (count overnights per parent over a year, then use an annual average if the schedule varies by season)
Practical tip: If your schedule changes (school breaks/holidays), total it for the year rather than guessing a rough percentage.
Childcare and medical costs
- Childcare invoices / provider statements (monthly)
- Health insurance premium notices (monthly)
- Medical bills for uncovered expenses
Convert to a monthly average if they don’t occur every month
Keep receipts or statements if you plan to refine the numbers later. Clean documentation can make it easier to update the estimate.
Extraordinary expenses
- Bills and statements for transportation, therapy, specialty care, or other regularly recurring items
- Work-linked costs when they relate to employment (if applicable to your situation)
Warning (practical): Try not to guess childcare/medical figures. Small differences can meaningfully affect estimates, especially across multiple children and time periods.
Run it
Once your inputs are gathered, you can run DocketMath using the tool name alimony-child-support for Michigan (US-MI).
Enter the inputs in DocketMath and run the Alimony Child Support calculation to generate a clean breakdown: Run the calculator.
Recommended run order (to keep things organized)
Run child support first using:
- number of children
- each parent’s gross monthly income
- parenting time/overnights
- childcare
- medical/insurance inputs (if requested)
Run alimony next using:
- each spouse’s gross (and/or net) monthly income
- overtime/bonuses/commissions (if you can average them)
- self-employment income inputs
- health insurance costs for the spouse (if prompted)
This order helps prevent mixing household numbers that should be modeled separately.
How outputs can change based on inputs
Use this as a quick “what changed and why” guide when you revise values:
| Input you adjust | Common direction of effect (estimate) | Why it changes |
|---|---|---|
| More parenting time credited to a parent | Often lowers that parent’s child support amount | Greater shared time typically reduces the assumed cost burden |
| Higher childcare costs | Often increases child support | Childcare is usually treated as an added/allocated cost |
| Higher gross income for a parent | Often increases that parent’s child support obligation | Support calculations scale with income |
| Updating medical/insurance premiums | Often increases or decreases support | Covered vs. uncovered costs and insurance allocations can shift the totals |
| Switching from averaged irregular income to current income | Can materially change estimates | Bonus/commission timing can affect the monthly average |
If you’re thinking about timeframes (repayment context, not advice)
If your goal involves enforcement or retroactive adjustments, remember Michigan’s general 6-year baseline referenced in MCL § 767.24(1). For this article, we treat it as the default general period because no claim-type-specific sub-rule was identified for this content.
