Worked example: Alimony Child Support in Alabama
6 min read
Published April 15, 2026 • By DocketMath Team
Example inputs
Below is a worked example showing how DocketMath calculates alimony and child support in Alabama (US-AL). This example is designed to help you understand what to enter and how results respond to changes. It’s not legal advice—treat it as an educational walkthrough of how a jurisdiction-aware calculator can structure family-law numbers.
Scenario (Alabama)
Assume this situation:
- Filing context: Alabama divorce case with both child support and alimony
- Number of children: 2 (minors)
- Parent A (Payor):
- Gross monthly income: $6,500
- Other income/allowances: $0 (none entered)
- Health insurance contribution for children: $250/month
- Spends 50% of the time with the children (entered as shared custody)
- Parent B (Payee):
- Gross monthly income: $4,000
- Receives child care/other support: $0 (none entered)
- Child support-related costs:
- Child health insurance: $250/month (entered above)
- No daycare adjustment entered in this run
- Alimony assumptions (for the calculator):
- Type selected in DocketMath: Periodic alimony (not a lump sum)
- Start date: immediately (calculator uses it only to label the schedule)
- Length of term: 36 months (entered as the duration)
Inputs you’ll typically see in DocketMath for this calculator
Check the boxes below to match what this example uses:
- Parent A gross monthly income: $6,500
- Parent B gross monthly income: $4,000
- Number of children: 2
- Health insurance for children: $250/month
- Custody/parenting-time: shared custody
- Alimony type: periodic
- Alimony duration: 36 months
Why these fields matter
In DocketMath, the child support outcome is sensitive to:
- combined incomes (more income typically increases the baseline support),
- parenting-time / custody allocation (shared time often shifts how routine child costs are allocated),
- and health insurance adjustments.
Alimony output is sensitive to:
- the case framing for the alimony term (duration selection),
- the income gap you provide,
- and the calculator’s periodic-alimony logic.
Note: DocketMath’s jurisdiction awareness means Alabama-specific structures and rules are applied when available; however, real cases can involve additional evidence (expenses, debts, guideline deviations) that aren’t captured in a simplified calculator input screen.
Example run
You can reproduce this example by opening the tool here first: Alimony & Child Support calculator. Then enter the scenario values.
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-by-step entries (Alabama / US-AL)
- Select jurisdiction: **Alabama (US-AL)
- Choose both calculations: child support and periodic alimony.
- Enter incomes:
- Parent A: $6,500
- Parent B: $4,000
- Enter children:
- 2 children
- Enter health insurance:
- $250/month
- Enter custody:
- shared custody (50/50)
- Enter alimony:
- periodic
- duration: 36 months
What DocketMath reports (illustrative output format)
After you run the calculation, DocketMath typically provides results in two buckets.
1) Child support (monthly)
DocketMath outputs:
- **Child support guideline amount (monthly)
- Potential line items (e.g., health insurance adjustment) depending on how the tool is configured
For this example, the child support result is:
- Estimated child support: $1,725/month
(This is a calculator output for the entered facts above; your number will change with custody split and income inputs.)
2) Alimony (monthly)
For periodic alimony, DocketMath reports:
- Estimated periodic alimony: $900/month
- and a schedule implied through the selected duration
For this example:
- Estimated alimony: $900/month
- Total alimony term covered by entry: 36 months
Combined payment estimate
DocketMath then helps you interpret total monthly support as a simple sum:
- Total estimated monthly support:
- Child support $1,725
- Alimony $900
- = $2,625/month
Quick interpretation checklist
Use this checklist to sanity-check the reasonableness of changes:
Warning: If your parenting-time isn’t truly 50/50 (for example, 80/20), using a shared-custody entry can overstate or understate the child support portion.
Sensitivity check
To understand how DocketMath responds, adjust one variable at a time and watch the 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.
Sensitivity 1: Change custody split (shared → more time for Parent B)
Keep everything the same, but change parenting-time to Parent A has less time (e.g., 70/30). Enter that split (or the closest option available).
Expected effect (directionally):
- Child support generally tends to move upward for the parent who has less time, because the “more days” parent has higher routine cost burden.
Illustrative result:
- Child support increases from $1,725 → $1,980/month
- Alimony stays $900/month in this example because we did not change the alimony term inputs.
New combined estimate:
- $1,980 + $900 = $2,880/month
Sensitivity 2: Increase Parent A income by $500
Adjust Parent A gross monthly income from $6,500 → $7,000, keeping custody and health insurance unchanged.
Expected effect:
- More combined income typically increases guideline child support.
- Alimony often changes when the income gap changes, though the exact math depends on the calculator’s periodic-alimony logic.
Illustrative result:
- Child support: $1,725 → $1,910/month
- Alimony: $900 → $975/month
New combined estimate:
- $1,910 + $975 = $2,885/month
Sensitivity 3: Remove health insurance input ($250/month → $0)
Keep incomes, children count, and custody the same. Set health insurance for children to $0/month.
Expected effect:
- The child support portion typically adjusts because insurance is one of the measurable child-related expenses.
Illustrative result:
- Child support: $1,725 → $1,610/month
- Alimony: stays $900/month (in this simplified structure)
New combined estimate:
- $1,610 + $900 = $2,510/month
Sensitivity summary table (what changed)
| Change made | Child support (monthly) | Alimony (monthly) | Combined estimate (monthly) |
|---|---|---|---|
| Baseline (50/50 custody, $6,500 income, $250 insurance) | $1,725 | $900 | $2,625 |
| Custody shifts toward Parent B (70/30) | $1,980 | $900 | $2,880 |
| Parent A income increases to $7,000 | $1,910 | $975 | $2,885 |
| Health insurance removed | $1,610 | $900 | $2,510 |
