What this calculator does

DocketMath’s Alimony & Child Support Estimator for Louisiana (US-LA) helps you generate a rough estimate of potential support amounts using the inputs you provide—then shows how changes to those inputs can move the numbers.

Use it to model questions like:

• What happens if gross monthly income changes by $1,000?
• How does how many children you’re supporting affect the estimate?
• What if the custody split (or time-sharing) you enter is different from what you’re considering?
• How do health insurance and child care amounts you enter affect the estimate?
• If a request involves support for a spouse, how might the estimate change with factors you choose to include?

This guide also walks you through a step-by-step example, highlights common Louisiana scenarios, and provides accuracy tips so your inputs are consistent and defensible.

When to use it

You’ll get the most value from the DocketMath estimator when you’re in a phase where estimating is useful for planning—such as:

• Before filing or responding to a petition (to understand ballpark ranges).
• During settlement discussions (to test “what-if” positions).
• When updating information (e.g., a job change, a new child-care arrangement, or a custody schedule change).
• After a temporary order to sanity-check whether a new set of facts appears to move the estimate in a reasonable direction.
• Preparing documentation for an attorney or mediator—so you can quickly identify which inputs matter most.

Recommended timing checkpoints (practical approach)

• Gather income documents (pay stubs, W-2s, recent tax returns).
• Confirm the child-related numbers (child-care invoices, insurance premiums).
• Clarify the time-sharing concept you’ll enter (even if it’s an approximation at first).

A caution tied to timing—why calendars matter

Louisiana has multiple prescription (limitations) rules that can affect how claims are treated, depending on the type of claim and procedural posture. For example, Louisiana’s prescription framework includes deadlines such as:

• La. Rev. Stat. Ann. § 9:2800.9 with a 1-year period (exception O2), and related references in La. Code Crim. Proc. arts. 571–572 (3 years—exception O2; 1 year—exception P2 depending on the cited subsection).
• La. Rev. Stat. § 9:5605(E) includes a 1-year deadline (exception M5).
• La. Civ. Code art. 3493.11 includes a 2-year period (exception M6).
• La. Code Crim. Proc. art. 572 includes a 0.5-year period (exception V1).
• La. Code Crim. Proc. art. 571 includes a 1-year period (exception P2).

Those deadlines are not a substitute for legal analysis of your situation, but they’re a reminder: support-related issues often become time-sensitive once a dispute begins. Keep timelines documented.

Step-by-step example

Below is a concrete example of how to use the DocketMath calculator inputs and interpret results. This example is intentionally simplified so you can map it directly to your data.

Example: Modeling potential monthly child support (Louisiana)

Assume you want a rough estimate for a household with:

• 2 children
• One parent (Parent A) has $5,000 gross monthly income
• The other parent (Parent B) has $3,000 gross monthly income
• You approximate a shared schedule that you enter as a mid-range custody split (you’ll use the custody/time-sharing input that matches your planning assumption)
• Parent paying support also has:

  • $250/month child-care costs
  • $120/month health insurance premium attributable to the children

Step 1: Start the DocketMath tool

Go to the primary CTA: **Alimony & Child Support Estimator

Step 2: Enter the basic facts

Checkboxes or selection controls in the tool typically include items like:

• Number of children: 2
• Income for Parent A: $5,000/month
• Income for Parent B: $3,000/month
• Custody/time-sharing input: choose the option closest to your scenario (or enter your best estimate)

Step 3: Add child-related costs (if the tool asks)

Enter:

• Child-care: $250/month
• Health insurance: $120/month

If the tool includes optional switches (e.g., “include child-care” or “include health insurance”), turn them on only if the costs are truly part of your situation.

Step 4: Review the output structure

The calculator should display one or more estimated results, commonly:

• An estimated monthly child support figure
• Potential related components depending on what you entered
• Sometimes an estimate for spousal support as well (if you toggle/enter alimony-related fields)

Interpret the number as a planning estimate, not a binding order.

Step 5: Run quick “what-if” tests

Change one variable at a time to see how sensitive the outcome is:

• Increase Parent A income from $5,000 → $5,500
• Keep custody and costs the same
• Note how the estimate moves

This is one of the best ways to understand what the court (or negotiators) would likely see as the “big levers” in your fact pattern.

Common scenarios

Louisiana households vary widely. The estimator is most useful when your inputs reflect the scenario you’re modeling. Here are frequent situations people try to run through DocketMath:

Scenario 1: New job or overtime changes income

• Input what you know now: base pay vs. variable overtime
• If overtime is consistent (e.g., historical pattern over multiple pay periods), consider whether the tool has a way to approximate consistent income

Scenario 2: Health insurance premium changes

• Enter the premium amount you actually pay or the portion attributable to the children
• If the plan is provided through a different employer after job change, rerun the estimate with the updated number

Scenario 3: Child-care arrangement starts or ends

• If you currently pay child-care, include it
• When a new arrangement begins, rerun the estimate rather than keeping the old number

Scenario 4: Custody/time-sharing is not yet final

• Enter your best working approximation (you can run multiple versions)
• Use separate runs for different plausible schedules to see how much the estimate swings

Scenario 5: Two different alimony requests under discussion

If you’re modeling alimony-like requests:

• Use the estimator’s alimony sections only if you have corresponding fields available
• Run a baseline estimate first, then add/modify alimony inputs and compare

Tips for accuracy

You’ll get better estimates when your inputs are consistent and grounded in actual records. Use these tips to tighten accuracy:

1) Use monthly amounts, not yearly averages

If your tool expects monthly figures, convert carefully:

• If you have annual income data, divide by 12
• For hourly or variable pay, base your estimate on the most relevant recent period you can support

2) Reconcile “gross” vs. “net”

Many support frameworks begin with gross income concepts (the exact legal treatment can be nuanced). For estimation:

• Enter gross monthly income if the tool labels it as gross
• If you only have net pay, look for an input path that accepts net and be consistent across runs

3) Document your child-care and insurance numbers

If the tool allows cost inputs, make sure they match what you can show:

• child-care receipts or invoices
• the insurance premium and the portion attributable to children

4) Choose the custody/time-sharing input closest to reality

Even if your schedule isn’t final, pick a consistent baseline:

• Run Version A with the schedule you expect soonest
• Run Version B with the alternate schedule you’re likely to negotiate

5) Keep a small change log

Create a simple checklist for each run:

This makes it much easier to explain your own numbers during settlement discussions.
