How Nebraska Child Support Is Calculated
- Add both parents' net monthly income (annualized income divided by 12) to get combined monthly net income.
- Look up the combined income and number of children in Table 1 (Income Shares Formula) to get the basic child support amount.
- Each parent's share is their percentage of combined net income, multiplied by the Table 1 amount.
- The paying parent's obligation may not reduce their own net income below the Basic Subsistence Limitation ($1,330/month as of 2026) -- except that a minimum support amount (the greater of $50/month or 10% of the paying parent's net income) may still be ordered even if it dips below that limitation.
- This calculator models the standard primary-custody case (Worksheet 1) only. Joint Physical Custody (each parent has more than 142 parenting days/year) and Split Custody use entirely different worksheets and are not modeled here. The discretionary Visitation/Parenting Time reduction (up to 80% for extended periods) is also not modeled.
Nebraska Child Support Worksheet Walkthrough
Example (adapted from the guidelines' own illustration, updated for the current 2026 Basic Subsistence Limitation): Parent F has net monthly income of $1,500, Parent M has net monthly income of $500 (combined $2,000). There are three children, in Parent M's custody.
- Combined net monthly income: $1,500 + $500 = $2,000.
- Table 1 at $2,000 combined, three children: $712.
- Parent F's income share: $1,500 / $2,000 = 75%.
- Parent F's raw prorated share: $712 x 75% = $534.
- Basic Subsistence Limitation check: Parent F's own income ($1,500) minus the $1,330 limitation leaves only $170 available for support -- since $534 would leave Parent F with just $966 (below $1,330), the obligation is capped at $170.
- Parent F pays: $170/month.

FAQ
How is child support calculated in Nebraska?
Add both parents' net monthly income (annualized income divided by 12) to get combined monthly net income. Look up the combined income and number of children in Table 1 (Income Shares Formula) to get the basic child support amount. Each parent's share is their percentage of combined net income, multiplied by the Table 1 amount. The paying parent's obligation may not reduce their own net income below the Basic Subsistence Limitation ($1,330/month as of 2026) -- except that a minimum support amount (the greater of $50/month or 10% of the paying parent's net income) may still be ordered even if it dips below that limitation. This calculator models the standard primary-custody case (Worksheet 1) only. Joint Physical Custody (each parent has more than 142 parenting days/year) and Split Custody use entirely different worksheets and are not modeled here. The discretionary Visitation/Parenting Time reduction (up to 80% for extended periods) is also not modeled.
What is Nebraska's Basic Subsistence Limitation?
A paying parent's support, child care, and health care obligation may not reduce their own net income below $1,330/month (updated annually, Neb. Ct. R. § 4-218) or the applicable federal poverty guideline -- except that the separate minimum support amount (the greater of $50/month or 10% of net income) can still apply even if it dips below that floor.
How does Joint Physical Custody change Nebraska child support?
When each parent's parenting time exceeds 142 days per year, Nebraska applies a rebuttable presumption that support should be calculated using a different form (Worksheet 3), not the standard primary-custody worksheet this calculator uses. Between 109 and 142 days for one parent, using Worksheet 3 is at the court's discretion.
What is Nebraska's minimum child support amount?
Neb. Ct. R. § 4-209 sets minimum support at whichever is greater: $50/month or 10% of the paying parent's net income. This minimum can apply even in cases where it would otherwise reduce the paying parent below the Basic Subsistence Limitation.

This calculator does not model: the discretionary Visitation or Parenting Time Adjustment (§ 4-210 -- up to an 80% reduction during parenting time periods of 28+ days per 90-day period, entirely at the court's discretion, not a fixed formula); Joint Physical Custody (§ 4-212 -- when each parent's parenting time exceeds 142 days/year, a rebuttable presumption requires an entirely different Worksheet 3 calculation); or Split Custody (§ 4-211, a separate Worksheet 2 offset calculation). This calculator models the standard primary-custody case (Worksheet 1) only. Above the $20,000/month combined income shown in Table 1, Nebraska's guidelines do not provide an automatic extension formula -- courts determine the amount case-by-case.
