The amount of child maintenance to pay depends primarily on the paying parent's gross weekly income and the number of children who need support.
Standard child maintenance rates:
- For one child: 12% of gross weekly income
- For two children: 16% of gross weekly income
- For three or more children: 19% of gross weekly income
Income thresholds affecting rates:
- If gross weekly income is between £200 and £800, the above percentages apply directly (Basic rate).
- If gross weekly income is above £800 and up to £3,000, a Basic Plus rate applies, where the first £800 is charged at the basic percentage, and income between £800 and £3,000 is charged at a lower percentage (e.g., 9% for one child, 12% for two, 15% for three or more).
Reduced rate:
- If gross weekly income is below £200 but over £100, a reduced rate applies, which includes a flat £7 plus an additional percentage of the income over £100.
Nil rate:
- No child maintenance is required if gross weekly income is below £7 or under certain conditions such as being in full-time education, prison, or receiving specific benefits.
The Child Maintenance Service (CMS) can calculate the exact amount based on individual circumstances and manage payments either directly between parents or through the CMS system with possible fees. To get a precise figure, using an official child maintenance calculator or contacting the CMS is recommended. This system reflects the rules and percentages used in the UK.
