Inputs you will need
Run this scenario in DocketMath using the Alimony Child Support calculator.
If you’re using DocketMath to estimate alimony and child support in New Jersey, the calculator can’t produce a meaningful estimate without key financial facts. Below is a jurisdiction-aware input checklist for US-NJ. Use this as a data-gathering plan before you click /tools/alimony-child-support.
Note: This article is for information only. It explains what inputs affect results and where to find them. It’s not legal advice and doesn’t replace advice from a qualified New Jersey family-law attorney.
Core inputs (most cases)
Start by collecting the basics for both parties:
Alimony-focused inputs to prepare
Alimony results often depend heavily on the parties’ financial picture and the relationship timeline, but you’ll still want these inputs ready:
Proof you should gather before running numbers
Even if the calculator is designed for speed, the best estimates usually come from clean documentation:
Statute timing note (general recordkeeping)
New Jersey’s general limitations period is 4 years, under N.J.S.A. 12A:2-725 (general/default period). The statute is commonly referenced for certain contract-related claims, not family support calculations specifically. However, if you’re organizing records to support a family-law matter, the 4-year general SOL is a practical planning reference for how long you may want to keep certain documents.

Where to find each input
To make data collection faster, here’s where most people typically locate each required input and what to look for.
| Input | Common place to find it | What to look for |
|---|---|---|
| Gross income (wages) | Pay stubs | YTD gross pay, regular vs. overtime, year-to-date bonuses |
| Bonuses/commissions | Employment statements, pay stubs | Whether they’re recurring or one-off |
| Self-employment income | Tax returns + profit/loss | Net income and adjustments |
| Parenting time | Existing custody schedule or proposed schedule | Number of overnights and weekdays/weekends |
| Number of children | Birth certificates / custody documents | Confirm names and birth dates for consistency |
| Health insurance premium | Employer benefits page or invoice | Premium amount paid per month |
| Childcare costs | Receipts/invoices | Monthly totals and dates of service |
| Existing support obligations | Prior orders, judgment documents | Monthly amounts and proof of current payments |
| Marriage length | Marriage certificate + timeline | Start date and separation date used in your worksheet |
| Major debts/obligations | Statements and billing records | Fixed monthly payments (auto, student loans, etc.) |
Quick organization method (10–15 minutes)
Consider creating one folder per topic:
- Income folder: pay stubs, W-2s, 1099s, tax returns
- Child folder: parenting schedule + childcare + insurance premiums
- Alimony folder: marriage timeline + employment details + debts
This reduces re-checking details after you run a first pass in DocketMath.
Pitfall: Running the calculator with missing income details is one of the fastest ways to get a misleading estimate. If you don’t have bonus history or childcare figures ready, plan for output changes once you add those facts.
Run it
Once your inputs are assembled, open DocketMath → /tools/alimony-child-support and enter the US-NJ information using the tool’s jurisdiction-aware logic.
Enter the inputs in DocketMath and run the Alimony Child Support calculation to generate a clean breakdown: Run the calculator.
Step-by-step workflow
How outputs typically change when you change inputs
Even before fine-tuning, these categories generally drive the biggest shifts:
- Income level and consistency
- Higher gross income for one party often increases the support expectation tied to that income difference.
- Parenting time
- More time with the children often changes the child support allocation logic.
- Insurance and childcare
- Added documented childcare costs and premiums may increase the child-related monthly total (depending on how the calculator structures categories).
- Existing support
- Prior obligations can alter the final estimate because they can change the financial baseline used.
Suggested “two-run” accuracy strategy
Run the tool twice:
- Run 1 (rough, documented averages)
Use the last 8–12 weeks of pay and your most recent childcare/insurance amount. - Run 2 (tighten with tax history)
Replace averages with YTD/annual figures or tax-return-based income if self-employment is involved.
This usually produces a more useful estimate without requiring perfect data on the first try.
Warning: Calculator results are estimates. New Jersey family-law outcomes depend on the full facts and procedural posture of the case, which a tool can’t fully capture.
