How does the Child Support Agency calculate child maintenance?
The Child Support Agency (CSA) calculates an amount using rules set out by Child Support law. This amount is based on: • the net income of the non resident parent, and • the number of qualifying children the non resident parent lives apart from. You can get an idea of what your payments might be, using the Child Maintenance Options calculator. You could also use this figure as a starting point for a Private Agreement.
