Child Support Calculators

First, enter your best estimate of the total amount of child support you’re owed. Next, enter the amount of current, on-going support you were supposed to receive and select how often you were supposed to receive it. Finally, select your state and hit “calculate!”

Most states allow interest to be added to the child support payments that are missed. You’ll probably be surprised by the impact the interest has on the amount you’re owed! Keep in mind, though, that this calculator can’t take into consideration any of the other important factors that influence how much you’re owed. Once you get started with Support Collectors, we’ll work with you to determine the correct amount.
