How to use this service

To use the calculator you'll need to know:

• the non-resident parent's net weekly income (there’s an online tool to help you work this out)
• the number of children the maintenance is to be paid for
• the number of nights, on average, the non-resident parent has the child for each year
• the number of other children living in the non-resident parent’s household

The calculator can give you an indication of the amount of maintenance that might be payable with an arrangement through the Child Support Agency.
