Child maintenance calculator


Use the calculator to agree on a child maintenance amount if you’re arranging it yourselves, or to get an idea of the statutory amount the government would work out for you.

What you need to know:

  • the calculator gives an estimate (it won’t cover variations for exceptional circumstances)
  • you need information about your income
  • if you have children with more than 1 person, you must make a separate calculation for each person you want to have a child maintenance agreement with
