What This Calculator Does

This child support guideline calculator estimates monthly child support obligations using the income shares model adopted by 41 states, which bases child support on both parents' incomes and the cost of raising children. It factors in parental incomes, number of children, custody percentage, healthcare premiums, and childcare costs to produce a proportional support estimate.

Real-World Use Cases

Common Mistakes to Avoid

• Using gross income instead of the guideline income definition. Most states use gross income minus certain deductions (union dues, other child support orders, mandatory retirement).

• Ignoring the custody parenting time adjustment. States adjust the base obligation when the non-custodial parent has significant parenting time (typically above 20%–35% of nights). Higher parenting time reduces the obligation.

• Treating this as a legally binding calculation. Income shares tables vary by state, and courts have discretion to deviate from guidelines for extraordinary expenses or circumstances.

• Not including self-employment income correctly. Self-employed parents use gross self-employment income minus legitimate business expenses, not net income after all deductions.
