How to calculate Alimony Child Support in Idaho

Quick takeaways

• In Idaho, DocketMath uses the framework from Idaho’s Child Support Guidelines and the Idaho spousal maintenance statute (Idaho Code § 32-705) to help you calculate guideline-driven amounts behind an “alimony + child support” workflow.
• The practical way to run the tool is to separate your inputs into:

  1. child support guideline inputs (driven by combined monthly gross income and the schedule), and
  2. spousal maintenance inputs (used under the Idaho § 32-705 workflow inside the calculator).
• Idaho’s guideline setup includes a combined monthly gross schedule that starts at $500 and includes checkpoints such as $800, $1,000, $2,000, $5,000, $10,000, $15,000, $20,000, and $25,000.
• For very high incomes, DocketMath uses a presumptive income cap set to $300,000 in the verified configuration.
• DocketMath enforces a minimum support order of $50 to prevent outputs from dropping below that floor.

Inputs you need

Before you open /tools/alimony-child-support, gather your information. Having the inputs ready helps you avoid rerunning the tool because one missing or incorrect number can change the result.

Income & household facts (needed for both parts of the workflow)

• Monthly gross income for each parent (the tool uses combined monthly gross for the Idaho child support guideline schedule)
• Number of children covered by the support calculation

Spousal maintenance inputs (needed for the “alimony” portion)

• Spousal maintenance context facts required by DocketMath’s Idaho workflow (the calculator will prompt you for what it needs based on the Idaho setup)
• Confirmation you’re using the Idaho setting (US-ID), so results are tied to the Idaho framework and outputs reflect the Idaho rules configuration

Sanity-check numbers (useful before running)

• Does your expected combined monthly gross land where you think it should on the guideline schedule? Common schedule checkpoints in the verified configuration include $500, $800, $1,000, $2,000, $5,000, $10,000, $15,000, $20,000, and $25,000.
• If you expect very high income, remember DocketMath applies an income cap at $300,000 (presumptive) in the guideline configuration—so the guideline amount won’t keep scaling in the same way past that point.

How the calculation works

DocketMath’s Idaho “alimony + child support” workflow is best understood as two coordinated calculations:

1. a child support guideline calculation anchored in Idaho’s Child Support Guidelines framework, and
2. a spousal maintenance calculation anchored in Idaho Code § 32-705.

1) Compute the child support guideline portion from combined monthly gross

Idaho’s child support guidelines use a schedule driven by combined monthly gross income. In the verified configuration, DocketMath includes schedule checkpoints such as:

• $500
• $800
• $1,000
• $2,000
• $5,000
• $10,000
• $15,000
• $20,000
• $25,000

As your combined monthly gross increases, the tool moves you to the corresponding schedule position used in its guideline engine.

2) Apply Idaho-specific guardrails inside the guideline calculation

DocketMath applies verified guideline configuration rules that can significantly affect outcomes:

• Presumptive income cap: $300,000
  If the guideline computation would otherwise go beyond this cap, the tool uses the configured cap behavior rather than continuing to scale indefinitely.
• Minimum support order: $50
  If the guideline-driven amount would otherwise fall below the minimum, DocketMath keeps the output from dropping under $50.

Practical impact: even if you focus only on the schedule table, the $300,000 presumptive cap and the $50 minimum can change the final guideline amount.

3) Compute the spousal maintenance (“alimony”) portion using Idaho Code § 32-705

For the spousal maintenance side, DocketMath routes your inputs through the Idaho Idaho Code § 32-705 workflow.

• The calculator will prompt for the spousal maintenance inputs it needs for the Idaho setup.
• The result is shown as a distinct component in the overall “alimony + child support” view, even though you’re entering information in a single run.

4) Present a combined output you can compare

In DocketMath, the final output is designed to be a combined view of:

• child support (schedule-driven by combined monthly gross with the verified cap/minimum rules), and
• spousal maintenance (driven by the Idaho § 32-705 workflow).

That structure makes it easier to test scenarios, such as:

• changing monthly income inputs,
• changing the number of children, or
• updating the spousal maintenance-related inputs and re-running.

Common pitfalls

These are common reasons people think the “alimony + child support” output is wrong after running DocketMath in Idaho:

1. Entering yearly income instead of monthly gross

   • Idaho’s schedule is keyed to combined monthly gross income. Enter monthly figures so the tool matches the guideline schedule mechanics.

2. Assuming the schedule scales forever at high income

   • DocketMath applies an income cap at $300,000 (presumptive). If you expected unlimited scaling, the output may appear lower than expected.

3. Overlooking the $50 minimum

   • If numbers are low enough, the minimum support order of $50 can control the result rather than the raw schedule math.

4. Updating only one set of inputs

   • Child support responds primarily to changes in combined monthly gross and number of children.
   • Spousal maintenance responds to changes in the spousal maintenance inputs the tool requests under Idaho Code § 32-705.
     If you adjust income and see no meaningful change in the “alimony” portion, check that the relevant spousal maintenance fields were updated too.

5. Working near schedule checkpoints

   • Because the schedule uses checkpoints (for example, around $800, $1,000, $2,000, $5,000, $10,000), small changes can shift the tool between schedule regions. Running a “one change at a time” comparison can reveal sensitivity.

Next steps

1. Open the calculator: /tools/alimony-child-support
2. Select Idaho (US-ID) in the jurisdiction setting so the tool uses the Idaho configuration.
3. Enter inputs in a consistent order:

   • monthly gross income for each parent
   • number of children
   • spousal maintenance-related inputs requested by the tool for the Idaho § 32-705 workflow
4. Run the calculation.
5. Do at least one sensitivity check:

   • change one income figure slightly and observe how the guideline-driven child support changes
   • update the spousal maintenance inputs and observe how the spousal maintenance portion changes
6. Save/export the scenario you want to compare, especially if you’re building a negotiation or budgeting range.
