The child maintenance calculator is for use in the UK. You can use it if you are married, divorced, a civil partner or a co-habitant. You can even use it if you are a lawyer, mediator, arbitrator or judge (all users are welcome). An important feature of this calculator is that the results are clearly laid out so you and your co-parent can be assured of accuracy and transparency to aid discussions. The result will be automatically converted into a PDF document and sent to your inbox. Even better, you can ask the calculator to email the calculation to your co-parent, lawyer or mediator, if you so wish.
The Child Maintenance Calculator is based on the rules introduced by the Child Maintenance Service on 29th July 2013. It uses a gross income model and applies different rates (or a combination of rates) in 5 bands:
| Rate | Paying parent’s gross weekly income |
|---|---|
| Basic | £200 to £800 |
| Basic Plus | £800.01 to £3,000 (the first £800 of income is taken into account using the Basic rate) |
| Reduced | £100.01 to £199.99 |
| Flat | £7.00 to £100 (or receives benefits) |
| Nil | Less than £7.00 |
The parent who should be paying, or wishes to pay, child maintenance is referred to below as the “paying parent”.
The child support maintenance calculator is undergoing maintenance and will be restored as soon as possible.
