Pennsylvania Child Support Calculator 2026 – Rule 1910.16-3 Guidelines
Use our free Pennsylvania child support calculator for 2026 to estimate guideline support under 231 Pa. Code Rule 1910.16-3. Pennsylvania uses Income Shares model. Therefore, the court combines both parents’ monthly net incomes and consults the statewide basic support schedule. For example, the schedule matches combined income from $800 to $30,000 to a basic obligation. In addition, if combined income exceeds $30,000, Rule 1910.16-3.1 high-income formula applies. As a result, our calculator uses the current 2026 schedule and formulas for an accurate estimate.

How Pennsylvania Child Support Is Calculated in 2026:
Pennsylvania calculation has four steps. First, determine net income. Second, lookup basic obligation. Third, split proportionally. Finally, adjust for custody time. Because of this process, support reflects income shares and substantial custody. In addition, courts add
mandatory expenses.
Step 1 – Determine Monthly Net Income:
Everything begins with monthly gross income, which Pennsylvania defines broadly. Wages, salary, business profits, interest, rental income, dividends, pensions, Social Security, disability, workers comp, unemployment, and lump-sum windfalls like lottery all count. However, gross is averaged over six months to smooth bonuses. From gross, court subtracts mandatory deductions per Rule 1910.16-2 to get net: federal/state/local income taxes, FICA Social Security/Medicare/self-employment taxes, unemployment and Local Services Tax, mandatory retirement contributions only (not elective 401k), mandatory union dues only, and alimony paid to other parent in same case.
Therefore, voluntary retirement, student loans, credit cards are not deducted automatically. Instead, parent must raise them as deviation factor.

Step 2 – Lookup Basic Support Obligation Rule 1910.16-3
Court adds both parents’ net incomes to get combined monthly net income and consults statewide schedule. The schedule lists combined incomes along one axis and number of children along other. Intersection gives basic support obligation representing total amount both parents together owe. For example, at $5,000 combined, one child about $1,000, two children about $1,710. At $10,000 combined, one child $1,550, two $2,530. At $30,000 combined, one child $2,360, two $3,760. As income rises, basic obligation increases but at slower rate. Therefore, each parent’s share equals percentage of combined income multiplied by basic obligation.
Step 3 – Handle High Income Over $30,000
Standard schedule tops at $30,000 combined. When parents earn more, Rule 1910.16-3.1 applies. Court starts with obligation at $30,000 as presumptive minimum, then adds percentage of every dollar above $30,000. For instance, one or two children 4% of excess, three children 4.5%, four 5%, five 5.5%, six 6% up to 6.3% for six children. As a result, for $35,000 combined for one child, obligation = $2,360 + 4% of $5,000 = $2,560. Once formula produces number, court can adjust up or down based on child’s actual reasonable needs with expense statements. However, court cannot drop below presumptive minimum at $30k without strong justification.
Step 4 – Adjust for Custody Time 40%+ and Equal Custody
When obligor has children 40% or more overnights, presumption for reduction kicks in per Rule 1910.16-4(c). Logic: parent who has kids nearly half time buys groceries, heat, daily costs. Court applies specific formula to reduce. For example, our calculator applies 10% reduction for illustration; actual PA uses formula. When parents split 50/50 equal custody, higher-income parent pays support to lower-income parent per 1910.16-4(d). However, formula ensures neither party ends with disproportionate share after support. If standard calculation would give obligee more than half combined income, court adjusts downward so combined income split evenly. Therefore, equal custody
ensures higher earner pays but income evened. In addition, if multiple children have different custody schedules, court averages overnight percentages.
Pennsylvania Child Support Example
Suppose Parent 1 net $4,000 and Parent 2 net $3,000. Combined $7,000. For 2 children, basic obligation about $2,100. Parent 1 share 57.1% = $1,199, Parent 2 share 42.9% = $901. If Parent 2 is custodial with less than 40% obligor time, Parent 1 pays $1,199 plus pro rata childcare $400 x 57.1% = $228, total $1,427 per month. However, if Parent 1 has 40%+ time, reduction applies: $1,199 x 0.9 = $1,079. For equal 50/50 with same incomes, higher earner Parent 1 pays difference ensuring incomes evened after support. As a result, custody time matters greatly
Additional Expenses On Top of Base
Basic schedule covers ordinary living costs, but several recurring expenses get added separately and split proportionally. Childcare necessary for work or school is divided, reduced for federal childcare tax credit. Health insurance premiums covering children split: if obligor pays premium, obligee’s share subtracted from support; if obligee pays, obligor’s share added. In addition, unreimbursed medical, dental, related costs not covered by insurance can be divided or ordered direct to provider. Therefore, total obligation equals basic share plus add-on shares.

Frequently Asked Questions:
Income Shares per Rule 1910.16-3. Combine monthly net incomes, lookup basic obligation from schedule $800-$30k based on children, split proportionally by income percentage. Over $30k uses Rule 1910.16-3.1: base at $30k plus 4%-6.3% of excess.
Gross wages, salary, business profits, interest, rental, dividends, pensions, Social Security, disability, workers comp, unemployment, lump-sum windfalls averaged over six months.

Higher-income parent pays lower-income parent per 1910.16-4(d). Court ensures neither party ends with more than half combined income after support, adjusting downward if needed so income evened.

High-income formula per 1910.16-3.1: presumptive minimum is obligation at $30k, then add 4% for 1-2 children, 4.5% for 3, 5% for 4, 5.5% for 5, 6%-6.3% for 6 of every dollar over $30k, subject to reasonable needs.
Yes, added on top of basic. Childcare necessary for work/school divided after tax credit. Health insurance premiums covering children split: obligor’s payment reduces support by obligee share, obligee’s payment adds obligor share.
