Child Maintenance Calculator
This section will help you to calculate how much child maintenance is likely to be due. Please note that this website can only give you a rough guide to how much you may be asked to pay or might expect to receive. It is intended only for guidance, to help parents who live apart make a decision about whether to apply to us for a calculation or to reach a private agreement. The amount of child maintenance worked out by our online calculator may be different from the child maintenance that we worked out and asked a non-resident parent to pay, or the amount that has been agreed in court as part of a consent order. This should not be used as grounds for appealing against our decision or for asking a court to change a consent order.
There are a number of circumstances which are not covered by the online calculator. These include when the non-resident parent's income is greater than £2000 per week, non-resident parents who receive a benefit, cases where maintenance will be shared between two or more parents with care and variations for exceptional circumstances.
The calculator does not apply to child maintenance calculated before March 2003.
