Massachusetts parents pay the most child support in the country, according to a new study.

Research by CustodyXChange, an app that helps divorced, separated or single parents create schedules for childcare, showed that on average Massachusetts parents pay $1,187 per month in child support.

In Virginia, which has a comparable cost of living to Massachusetts, parents pay an average of $402 per month, according to the study.

The CustodyXChange looked at a hypothetical heterosexual couple with two children – ages 7 and 10 – for their research. In the scenario the mother has the children 65 percent of the time and makes $45,000 a year. The father makes $55,000 in the test family, according to CustodyXChange. The parental income and custody arrangement was selected based on previous research and typical parent incomes from the Pew Research Center.

In Massachusetts, this hypothetical father would pay $1,187 a month.

Based on these same variables states in the Rocky Mountain region awarded the lowest payments, while New England gave the highest. On average, the father living in New England would pay $928 per month. If the father lived in the Rocky Mountain region he would pay $556 per month, according to the study.
