Calculate Your Child Maintenance Payments

Understanding your child maintenance obligations is crucial. Our simple calculator will help you estimate the payments based on your income, the number of children you support, and the number of nights they spend with you.

How Child Maintenance is Calculated

The Child Maintenance Service (CMS) uses a standard formula to calculate child maintenance payments. The payments are based on your gross weekly income and the number of children you support. Here's a quick breakdown:

• One child: 12% of your gross weekly income
• Two children: 16% of your gross weekly income
• Three or more children: 19% of your gross weekly income

Adjustments for Nights Spent with Children

If the children spend a significant number of nights with the paying parent, the child maintenance payments can be reduced. The standard reduction is as follows:

• 52 to 103 nights: 1/7th reduction
• 104 to 155 nights: 2/7th reduction
• 156 to 174 nights: 3/7th reduction
• 175 or more nights: 50% reduction plus an extra £7 per week reduction

Using the Calculator

Simply enter your gross weekly income, the number of children you support, and the number of nights they spend with you each year in the fields above, and click "Calculate Maintenance" to see your estimated payments.

Additional Considerations

In certain cases, other factors might influence the amount you need to pay, such as if you are already paying for the care of other children or if you have shared custody arrangements. These calculations can sometimes be adjusted to reflect these situations.

Detailed Guide to Child Maintenance Calculation

Child maintenance is a critical part of ensuring that children receive the financial support they need when parents are separated. The CMS formula is designed to be fair and takes into account various factors. Let’s dive deeper into the specifics of the calculation:

Gross Weekly Income

Your gross weekly income is your income before tax and National Insurance are deducted. This includes wages, benefits, and other sources of income. The CMS uses this figure to determine your payment bracket.

Number of Children

The percentage of your income that you pay in child maintenance increases with the number of children you are supporting. For one child, it is 12%, for two children, it is 16%, and for three or more children, it is 19%.

Nights Spent with Children

If your children spend a significant amount of time with you, this can reduce the amount you need to pay. The CMS provides reductions based on the number of nights your children spend with you each year. The more nights they spend with you, the greater the reduction in your payments. Here’s how it works:

• 52 to 103 nights: 1/7th reduction
• 104 to 155 nights: 2/7th reduction
• 156 to 174 nights: 3/7th reduction
• 175 or more nights: 50% reduction plus an extra £7 per week reduction

Special Circumstances

There are various special circumstances that can further adjust the amount you need to pay:

• If you are paying for the care of other children, this can be factored into the calculation.
• If you have shared custody, where children spend an equal or significant amount of time with each parent, the payments can be adjusted accordingly.
• High income: If your income exceeds a certain threshold, the CMS can take additional steps to ensure that payments are fair and sufficient for the child's needs.

Income Cap

The CMS has a maximum income cap for calculating child maintenance payments. As of 2024, the maximum gross weekly income used for calculations is £3,000. This cap ensures that the payments remain reasonable and proportional to income.

Ensuring Minimum Payments

The CMS ensures that there is a minimum payment amount to guarantee that children receive at least a basic level of support. Even with reductions, the minimum weekly payment is maintained to support the child's basic needs.

Example Calculations

Let’s look at a few examples to illustrate how the calculator works in practice:

Example 1:

A parent with a gross weekly income of £600, supporting one child who spends 80 nights a year with them.

• 12% of £600 = £72
• 1/7th reduction for 80 nights: £72 - (£72/7) = £61.71
• Estimated Weekly Maintenance: £61.71

Example 2:

A parent with a gross weekly income of £1,200, supporting two children who spend 110 nights a year with them.

• 16% of £1,200 = £192
• 2/7th reduction for 110 nights: £192 - (2 * £192/7) = £137.14
• Estimated Weekly Maintenance: £137.14

Frequently Asked Questions

What happens if my income changes?

If your income changes significantly, it’s important to inform the CMS as soon as possible. Your payments may need to be recalculated to reflect your new income level. Keeping the CMS updated ensures that payments remain fair and accurate.

How are bonuses and overtime considered?

Bonuses and overtime can be included in your gross weekly income calculation. The CMS looks at your overall income, including any additional earnings from bonuses and overtime, to determine your payment bracket.

Can I appeal a CMS decision?

If you believe there has been a mistake in the calculation of your payments, you can request a mandatory reconsideration from the CMS. If you are still not satisfied with the decision, you can appeal to the Social Security and Child Support Tribunal.

What if I have shared custody?

In cases of shared custody, where children spend a significant amount of time with both parents, the CMS can adjust the payments to reflect the shared care arrangement. It’s important to provide accurate information about the number of nights the children spend with each parent.
