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.

Please enter the non-resident parent's net weekly income. (Between £0 and £2000) e.g 193 etc.

You will find a calculator here to help you work out your weekly net income.
