Child Maintenance Calculator

This Child Maintenance Calculator can be used by parents in England & Wales as a tool to help them in discussions about the level of child support to be agreed after separation whether they be married, divorced, civil partners or co-habitants.

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:

Why use this maintenance calculator instead of the official govt one?

Good question. The UK government has provided its own calculator. That’s great, but it has the following major drawbacks:

  • It is not fully transparent. It only provides a basic summary. As a family law specialist, I know that there can be a high level of mistrust between parents after separation over their financial means. Our Child Maintenance Calculator displays more of the inputs in the calculation, such as the level of gross income entered or the level of pension contributions so both parents can be assured of reasonable accuracy. And if not, it can be quickly corrected.
  • There is no easy way to save or communicate the result of the government calculator to the other parent. Our Child Maintenance Calculator automatically converts the results into a clear PDF format which can be emailed directly to your inbox so you have a record of the result. Even better, you can ask the calculator to email the calculation to your co-parent, lawyer or mediator. Just let the person know they should be getting an email: some can get caught up by junk email filters.
  • The UK government’s child maintenance calculator has not been optimised for use on mobile devices (smart phones and tablets).
