Child support tools

These tools answer the questions that come up around a child support calculation: how many overnights a schedule gives each parent, how much unpaid support and interest have built up, whether today's circumstances are different enough to ask for a change, and what an hourly or weekly wage comes to each month. Each one uses the same official state rules as the main calculator.

• Parenting time calculatorCount overnights a year from a two-week schedule and see where they fall under your state’s rule.
• Arrears and interest calculatorWork out unpaid child support and the interest your state charges on it.
• Modification calculatorCompare a current order with the new guideline amount and your state’s change threshold.
• Income converterTurn an hourly, weekly or biweekly wage into monthly and yearly income.
