Child maintenance calculator

Our calculator can give you an indication of the amount of child maintenance you might pay* or receive based on the rules for the Child Support Agency's (CSA's) current scheme.

Our calculator can help you work out net weekly income.

Does the parent without the main day-to-day care receive benefits? *

 
 

Please note:
The figure for child maintenance that our calculator provides is only an indication. This figure may be different from the final figure the CSA calculates if you choose to arrange child maintenance through the CSA.

This calculator doesn't apply to child maintenance calculated by the CSA before March 2003.

There are some circumstances which are not covered by the calculator. These include:

  • where child maintenance will be shared between two or more parents with the main day-to-day care
  • variations for exceptional circumstances.

See which benefits the CSA takes into account

Working Tax Credit is counted as part of net income if the parent without main day to day care's earnings are higher than their partner's earnings. When parents earn the same, we include half of the Working Tax Credit in the child maintenance calculation.
