Example inputs

Run this scenario in DocketMath using the Alimony Child Support calculator.

This worked example shows how DocketMath can calculate a combined look at alimony and child support in Maryland using a jurisdiction-aware workflow for the relevant time horizon. It’s a modeling walkthrough—not legal advice—and the actual outcomes in a Maryland case depend on the facts the court finds credible (income, needs, health insurance, time-sharing/parenting time, marital history, and whether support is ordered initially vs. modified later).

Scenario (Maryland)

Assume a Maryland court is considering support for a calendar year. We’ll use a simple set of numbers that are realistic enough to demonstrate how the math behaves:

  • Mother (payee):
    • Annual gross earned income: $80,000
  • Father (payor):
    • Annual gross earned income: $120,000
  • Children:
    • Number of children: 2
  • Parenting time (rough split):
    • Father has about 45% of overnights/time
  • Health insurance for children:
    • Monthly premium attributable to the children (estimated): $250
  • Alimony type being modeled:
    • A temporary support calculation example (the focus here is on the workflow and time horizon, not claim-specific eligibility rules)
  • Back-pay time horizon (important for recalculation and accounting):
    • We’ll use the general limitations period as a default timing rule in the model: 3 years under Md. Code, Cts. & Jud. Proc. § 5-106.

Note (limitations period): Maryland’s “general/default” limitations period is 3 years for the civil action covered by Md. Code, Cts. & Jud. Proc. § 5-106. In this content, no claim-type-specific sub-rule was identified beyond that general period, so the example uses the default 3-year horizon.

DocketMath inputs (what you would enter)

In DocketMath → /tools/alimony-child-support, you’d typically provide inputs such as:

  • Payor annual gross income: $120,000
  • Payee annual gross income: $80,000
  • Number of children: 2
  • Estimated parenting-time share for payor: 45%
  • Monthly child health insurance cost: $250
  • Time horizon for “lookback”/accounting: 36 months (3 years)

To keep the walkthrough concrete, we’ll compute:

  • Monthly child support output (from the calculator’s child support rules)
  • Monthly alimony output (from the calculator’s alimony model)
  • A combined monthly total
  • A combined total over 36 months (using the general 3-year period)

Example run

Here’s how the example run behaves in DocketMath. Because DocketMath is designed to be jurisdiction-aware, the Maryland timing rule used in this workflow is anchored to:

  • Md. Code, Cts. & Jud. Proc. § 5-106 (general limitations period): 3 years

Step 1: Calculate a monthly child support estimate

Using the provided income figures and child-related inputs, DocketMath produces an estimated monthly child support figure.

Example output (illustrative for workflow demonstration):

  • Estimated child support (monthly): $2,050

Step 2: Calculate a monthly alimony estimate

Next, DocketMath uses the same income inputs (plus any relevant alimony modeling assumptions that the tool captures) to estimate monthly alimony.

Example output (illustrative for workflow demonstration):

  • Estimated alimony (monthly): $1,150

Step 3: Combine monthly totals

DocketMath then gives a combined monthly estimate by adding the two support streams:

OutputMonthly estimate
Child support$2,050
Alimony$1,150
Combined monthly total$3,200

Step 4: Apply the Maryland general 3-year horizon

For time-based accounting in this worked example, DocketMath uses the general limitations period of 3 years:

  • 36 months total, driven by Md. Code, Cts. & Jud. Proc. § 5-106.

So the combined total over 36 months is:

  • $3,200/month × 36 months = $115,200

Warning: A limitations period can affect whether and how far back amounts can be pursued or accounted for, but it does not automatically determine the merits of any support claim. Also, actual court orders may start on a specific date (or be modified), which can change the effective “months owed.”

Quick sanity check on scale

If you want to confirm the numbers feel plausible:

  • Combined monthly ($3,200) × 12 months = $38,400/year
  • Over 3 years = $115,200, which stays consistent with the 36-month multiplier.

Sensitivity check

Small input changes can meaningfully shift outcomes. Below are the most common “knobs” people adjust when exploring scenarios in DocketMath—especially in Maryland workflows that blend child support and alimony modeling.

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.

1) Income gap: payor income up/down

Change only the payor annual gross income while keeping everything else constant.

What to try:

  • Payor income from $120,000$130,000 (+$10,000)
  • Payor income from $120,000$110,000 (−$10,000)

Expected direction (general modeling behavior):

  • Higher payor income generally increases the combined monthly total.
  • Lower payor income generally decreases the combined monthly total.
Payor gross incomeCombined monthly estimateCombined 36-month total
$110,000$3,000$108,000
$120,000 (baseline)$3,200$115,200
$130,000$3,400$122,400

2) Number of children

If you change the number of children, DocketMath recalculates child support using the tool’s jurisdiction-aware logic.

Example thought experiment:

  • Move from 2 children1 child (same incomes and parenting-time assumptions)

Expected direction:

  • Fewer children typically reduces child support, which reduces the combined monthly total.

3) Parenting-time share for the payor

Parenting-time affects how child support is allocated. Explore small increments like 45% → 50%.

Expected direction:

  • Increasing the payor’s time share may reduce the payor’s child support obligation (depending on how the tool applies the parenting-time credit/adjustment).

4) Health insurance monthly cost

Try adjusting the monthly child health insurance cost:

  • $250 → $300 (+$50/month)

Expected direction:

  • Higher insurance costs generally increase the child-support-related component (often by adding or adjusting a cost credit/exchange).

5) Time horizon: 3 years vs. a shorter lookback

This is where jurisdiction awareness shows up in a very concrete way in the calculator.

In this worked example, DocketMath uses:

  • 3 years (36 months) under Md. Code, Cts. & Jud. Proc. § 5-106.

To see what the horizon does, compare:

  • 36 months (baseline, Maryland general period)
  • 24 months (for modeling comparison only—this is not claiming a different Maryland legal period)

Effect on total (holding monthly total constant at $3,200):

  • 24 months: $3,200 × 24 = $76,800
  • 36 months: $3,200 × 36 = $115,200

Pitfall: The “3-year” number here is the general/default limitations period. If the case involves circumstances where a different limitations rule applies, the correct timing horizon could differ. This walkthrough uses the default because no claim-type-specific sub-rule was identified for this example.
