There are usually six stages that the Child Maintenance Service follows when calculating a weekly child maintenance award. The first involves calculating the gross annual income of the supporting parent. This calculation is made with information sourced from HMRC and does not include student loans, student grants or tax credits.
The next stage is to assess whether there are other financial responsibilities, like pension payments or other child maintenance payments, that might affect the level of annual income, and then the final figure is converted into a weekly amount. The third stage in the process is to assess which rate is applicable. There are five levels of maintenance rates that can be applied, and they are all dependent on this gross weekly income.
