不是按收入比例?

In 2000 the Government passed legislation setting out a new method for calculating child support. 

The new system operates broadly as follows:

·         The NRP(non residential parent) pays a percentage of net income to the parent with care (PWC/residential parent).  This is set at 15% for 1 child, 20% for 2 children and 25% for 3 or   more children.  Net income is your income minus tax, NI contributions and your full pension contributions.

·         The income of the PWC (residential parent) is not taken into account under any circumstances
